RAISECOM MSG1500 X.00 is a 2.4/5 GHz band 11ac (Wi-Fi 5) router.
Apart from the general model, there are two ISP customized models:
China Mobile and China Telecom.
Specifications:
- SoC: Mediatek MT7621AT
- RAM: 256MiB DDR3
- Flash: 128MiB NAND
- Ethernet: 5 * 10/100/1000Mbps: 4 * LAN + 1 * WAN
- Switch: MediaTek MT7530 (SoC)
- WLAN: 1 * MT7615DN Dual-Band 2.4GHz 2T2R (400Mbps) 5GHz 2T2R (867Mbps)
- USB: 1 * USB 2.0 port
- Button: 1 * RESET button, 1 * WPS button, 1 * WIFI button
- LED: blue color: POWER, WAN, WPS, 2.4G, 5G, LAN1, LAN2, LAN3, LAN4, USB
- UART: 1 * serial port header (4-pin)
- Power: DC 12V, 1A
- Switch: 1 * POWER switch
MAC addresses as verified by vendor firmware:
use address source
LAN C8:XX:XX:3A:XX:E7 Config "protest_lan_mac" ascii (label)
WAN C8:XX:XX:3A:XX:EA Config "protest_wan_mac" ascii
5G C8:XX:XX:3A:XX:E8 Factory "0x4" hex
2.4G CA:XX:XX:4A:XX:E8 [not on flash]
The increment of the 4th byte for the 2.4g address appears to vary.
Reported cases:
5g 2.4g increment
C8:XX:XX:90:XX:C3 CA:XX:XX:C0:XX:C3 0x30
C8:XX:XX:3A:XX:08 CA:XX:XX:4A:XX:08 0x10
C8:XX:XX:3A:XX:E8 CA:XX:XX:4A:XX:E8 0x10
Since increment is inconsistent and there is no obvious pattern
in swapping bytes, and the 2.4g address has local bit set anyway,
it seems safer to use the LAN address with flipped byte here in
order to prevent collisions between OpenWrt devices and OEM devices
for this interface. This way we at least use an address as base
that is definitely owned by the device at hand.
Notes:
1. The vendor firmware allows you to connect to the router by telnet.
(known version 1.0.0 can open telnet.)
There is no official binary firmware available.
Backup the important partitions data:
"Bootloader", "Config", "Factory", and "firmware".
Note that with the vendor firmware the memory is detected only 128MiB
and the last 512KiB in NAND flash is not used.
2. The POWER LED is default on after press POWER switch.
The WAN and LAN1 - 4 LEDs are wired to ethernet switch.
The WPS LED is controlled by MT7615DN's GPIO.
Currently there is no proper way to configure it.
3. At the time of adding support the wireless config needs to be set up
by editing the wireless config file:
* Setting the country code is mandatory, otherwise the router loses
connectivity at the next reboot. This is mandatory and can be done
from luci. After setting the country code the router boots correctly.
A reset with the reset button will fix the issue and the user has to
reconfigure.
* This is minor since the 5g interface does not come up online although
it is not set as disabled. 2 options here:
1- Either run the "wifi" command. Can be added from LuCI in system -
startup - local startup and just add wifi above "exit 0".
2- Or add the serialize option in the wireless config file as shown
below. This one would work and bring both interfaces automatically
at every boot:
config wifi-device 'radio0'
option serialize '1'
config wifi-device 'radio1'
option serialize '1'
Flash instructions using initramfs image:
1. Press POWER switch to power down if the router is running.
2. Connect PC to one of LAN ports, and set
static IP address to "10.10.10.2", netmask to "255.255.255.0",
and gateway to "10.10.10.1" manually on the PC.
3. Push and hold the WIFI button, and then power up the router.
After about 10s (or you can call the recovery page, see "4" below)
you can release the WIFI button.
There is no clear indication when the router
is entering or has entered into "RAISECOM Router Recovery Mode".
4. Call the recovery page for the router at "http://10.10.10.1".
Keep an eye on the "WARNING!! tip" of the recovery page.
Click "Choose File" to select initramfs image, then click "Upload".
5. If image is uploaded successfully, you will see the page display
"Device is upgrading the firmware... %".
Keep an eye on the "WARNING!! tip" of the recovery page.
When the page display "Upgrade Successfully",
you can set IP address as "automatically obtain".
6. After the rebooting (PC should automatically obtain an IP address),
open the SSH connection, then download the sysupgrade image
to the router and perform sysupgrade with it.
Flash back to vendor firmware:
See "Flash instructions 1 - 5" above.
The only difference is that in step 4
you should select the vendor firmware which you backup.

Commit f4a79148f8cb ("ramips: add support for ipTIME AX2004M") was
reverted due to KERNEL_LOADADDR leakage, and it seems the problem can be
mitigated by moving the variable definition into Device/Default. By this,
KERNEL_LOADADDR redefined in a device recipe will not be leaked into the
subsequent device recipes anymore and thus will remain as a per-device

Device is the same as Xiaomi Mi Router 4A Gigabit, except of:
- 5G WiFi is MT7663
- addresses of leds, wifi and eth ports are slightly changed
Specs:
SoC: MT7621
CPU: 2 x 880 MHz
ROM: 16 MB
RAM: 128 MB
WLAN: MT7603, MT7663
MAC addresses:
WAN **** factory 0xe006 (label)
LAN *:f7 factory 0xe000
2.4 GHz *:f8 factory 0x0000+0x4 (mtd-eeprom+0x4)
5 GHz *:f9 factory 0x8000+0x4 (mtd-eeprom+0x4)
Installation:
Factory firmware is based on a custom OpenWrt 17.x.
Installation is the same as for Xiaomi Mi Router 4A Gigabit.
Probably the easiest way to install is to use the script from
this repository: https://github.com/acecilia/OpenWRTInvasion/pull/155
In a more advanced case, you can do everything yourself:
- gain access to the device through one of the exploits described
in the link above
- upload sysupgrade image to /tmp
- overwrite stock firmware:
# mtd -e OS1 -r write /tmp/sysupgrade.bin OS1
Recovery:
Recovery procedure is the same as for Xiaomi Mi Router 4A Gigabit.
Possible options can be found here:
https://openwrt.org/inbox/toh/xiaomi/xiaomi_mi_router_4a_gigabit_edition
One of the ways is to use another router with OpenWrt:
- connect both routers by their LAN ports
- download stock firmware from [1]
- place it inside /tmp/test.bin on the main router
- configure PXE/TFTP on the main router
- power off 4Av2, hold Reset button, power on
- as soon as image download via TFTP starts, Reset can be released
- blinking blue wan LED will indicate the end of the flashing process,
now router can be rebooted

H3C TX180x series WiFi6 routers are customized by different carrier.
While these three devices look different, they use the same motherboard

Compatibility mode is used to guarantee the connection of old devices
that only support WiFi4 or WiFi5.
TFTP + TTL Installation:
Although a TTL connection is required for installation, we do not need
to tear down it. We can find the TTL port from the cooling hole at the
bottom. It is located below LAN3 and the pins are defined as follows:
|LAN1|LAN2|LAN3|----|WAN|
--------------------
|GND|TX|RX|VCC|
1. Set tftp server IP to 192.168.124.99 and put initramfs firmware in
server's root directory, rename it to a simple name "initramfs.bin".
2. Plug in the power supply and wait for power on, connect the TTL cable
and open a TTL session, enter "reboot", then enter "Y" to confirm.
Finally push "0" to interruput boot while booting.
3. Execute command to install a initramfs system:
# tftp 0x80010000 192.168.124.99:initramfs.bin
# bootm 0x80010000
4. Backup nand flash by OpenWrt LuCI or dd instruction. We need those
partitions if we want to back to stock firmwre due to official
website does not provide download link.
# dd if=/dev/mtd1 of=/tmp/u-boot-env.bin
# dd if=/dev/mtd4 of=/tmp/firmware.bin
5. Edit u-boot env to ensure use default bootargs and first image slot:
# fw_setenv bootargs
# fw_setenv bootflag 0
6. Upgrade sysupgrade firmware.
7. About restore stock firmware: flash the "firmware" and "u-boot-env"
partitions that we backed up in step 4.
# mtd write /tmp/u-boot-env.bin u-boot-env
# mtd write /tmp/firmware.bin firmware
Additional Info:
The H3C stock firmware has a 160-byte firmware header that appears to
use a non-standard CRC32 verification algorithm. For this part of the
data, the u-boot does not check it so we can just directly replace it
with a placeholder.

Notice:
Since the stock firmware is based on OpenWrt and the configuration

Xiaomi Mi Router CR6606 is a Wi-Fi6 AX1800 Router with 4 GbE Ports.
Alongside the general model, it has three carrier customized models:
CR6606 (China Unicom), CR6608 (China Mobile), CR6609 (China Telecom)
Specifications:
- SoC: MediaTek MT7621AT
- RAM: 256MB DDR3 (ESMT M15T2G16128A)
- Flash: 128MB NAND (ESMT F59L1G81MB)
- Ethernet: 1000Base-T x4 (MT7530 SoC)
- WLAN: 2x2 2.4GHz 574Mbps + 2x2 5GHz 1201Mbps (MT7905DAN + MT7975DN)
- LEDs: System (Blue, Yellow), Internet (Blue, Yellow)
- Buttons: Reset, WPS
- UART: through-hole on PCB ([VCC 3.3v](RX)(GND)(TX) 115200, 8n1)
- Power: 12VDC, 1A
Jailbreak Notes:
1. Get shell access.
1.1. Get yourself a wireless router that runs OpenWrt already.
1.2. On the OpenWrt router:
1.2.1. Access its console.
1.2.2. Create and edit
/usr/lib/lua/luci/controller/admin/xqsystem.lua
with the following code (exclude backquotes and line no.):
```
1 module("luci.controller.admin.xqsystem", package.seeall)
2
3 function index()
4 local page = node("api")
5 page.target = firstchild()
6 page.title = ("")
7 page.order = 100
8 page.index = true
9 page = node("api","xqsystem")
10 page.target = firstchild()
11 page.title = ("")
12 page.order = 100
13 page.index = true
14 entry({"api", "xqsystem", "token"}, call("getToken"), (""),
103, 0x08)
15 end
16
17 local LuciHttp = require("luci.http")
18
19 function getToken()
20 local result = {}
21 result["code"] = 0
22 result["token"] = "; nvram set ssh_en=1; nvram commit; sed -i
's/channel=.*/channel=\"debug\"/g' /etc/init.d/dropbear; /etc/init.d/drop
bear start;"
23 LuciHttp.write_json(result)
24 end
```
1.2.3. Browse http://{OWRT_ADDR}/cgi-bin/luci/api/xqsystem/token
It should give you a respond like this:
{"code":0,"token":"; nvram set ssh_en=1; nvram commit; ..."}
If so, continue; Otherwise, check the file, reboot the rout-
er, try again.
1.2.4. Set wireless network interface's IP to 169.254.31.1, turn
off DHCP of wireless interface's zone.
1.2.5. Connect to the router wirelessly, manually set your access
device's IP to 169.254.31.3, make sure
http://169.254.31.1/cgi-bin/luci/api/xqsystem/token
still have a similar result as 1.2.3 shows.
1.3. On the Xiaomi CR660x:
1.3.1. Login to the web interface. Your would be directed to a
page with URL like this:
http://{ROUTER_ADDR}/cgi-bin/luci/;stok={STOK}/web/home#r-
outer
1.3.2. Browse this URL with {STOK} from 1.3.1, {WIFI_NAME}
{PASSWORD} be your OpenWrt router's SSID and password:
http://{MIROUTER_ADDR}/cgi-bin/luci/;stok={STOK}/api/misy-
stem/extendwifi_connect?ssid={WIFI_NAME}&password={PASSWO-
RD}
It should return 0.
1.3.3. Browse this URL with {STOK} from 1.3.1:
http://{MIROUTER_ADDR}/cgi-bin/luci/;stok={STOK}/api/xqsy-
stem/oneclick_get_remote_token?username=xxx&password=xxx&-
nonce=xxx
1.4. Before rebooting, you can now access your CR660x via SSH.
For CR6606, you can calculate your root password by this project:
https://github.com/wfjsw/xiaoqiang-root-password, or at
https://www.oxygen7.cn/miwifi.
The root password for carrier-specific models should be the admi-
nistration password or the default login password on the label.
It is also feasible to change the root password at the same time
by modifying the script from step 1.2.2.
You can treat OpenWrt Router however you like from this point as
long as you don't mind go through this again if you have to expl-
oit it again. If you do have to and left your OpenWrt router unt-
ouched, start from 1.3.
2. There's no official binary firmware available, and if you lose the
content of your flash, no one except Xiaomi can help you.
Dump these partitions in case you need them:
"Bootloader" "Nvram" "Bdata" "crash" "crash_log"
"firmware" "firmware1" "overlay" "obr"
Find the corespond block device from /proc/mtd
Read from read-only block device to avoid misoperation.
It's recommended to use /tmp/syslogbackup/ as destination, since files
would be available at http://{ROUTER_ADDR}/backup/log/YOUR_DUMP
Keep an eye on memory usage though.
3. Since UART access is locked ootb, you should get UART access by modify
uboot env. Otherwise, your router may become bricked.
Excute these in stock firmware shell:
a. nvram set boot_wait=on
b. nvram set bootdelay=3
c. nvram commit
Or in OpenWrt:
a. opkg update && opkg install kmod-mtd-rw
b. insmod mtd-rw i_want_a_brick=1
c. fw_setenv boot_wait on
d. fw_setenv bootdelay 3
e. rmmod mtd-rw
Migrate to OpenWrt:
1. Transfer squashfs-firmware.bin to the router.
2. nvram set flag_try_sys1_failed=0
3. nvram set flag_try_sys2_failed=1
4. nvram commit
5. mtd -r write /path/to/image/squashfs-firmware.bin firmware
Additional Info:
1. CR660x series routers has a different nand layout compared to other
Xiaomi nand devices.
2. This router has a relatively fresh uboot (2018.09) compared to other
Xiaomi devices, and it is capable of booting fit image firmware.
Unfortunately, no successful attempt of booting OpenWrt fit image
were made so far. The cause is still yet to be known. For now, we use
legacy image instead.

Installation
Connect to one of LAN (yellow) ethernet ports,
Open router configuration interface,
Go to Toolbox > Firmware,
Browse for OpenWrt factory image with dlf extension and hit Apply,
Wait few minutes, after the Power LED will stop blinking, the router is
ready for configuration.
Known issues
Some USB 2.0 devices work at full speed mode 1.1 only
MAC addresses
factory partition only contains one (binary) MAC address in 0x4.
u-boot-env contains four (ascii) MAC addresses, of which two appear
to be valid.
factory 0x4 **:**:**:**:b9:84 binary
u-boot-env ethaddr **:**:**:**:b9:84 ascii
u-boot-env wanaddr **:**:**:**:b9:85 ascii
u-boot-env wlanaddr 00:AA:BB:CC:DD:12 ascii
u-boot-env iNICaddr 00:AA:BB:CC:DD:22 ascii
The factory firmware only assigns ethaddr. Thus, we take the
binary value which we can use directly in DTS.
Additional information
OEM firmware shell password is: SitecomSenao

Installation

Using the webcmd interface
--------------------------
Warning: Do not update to the latest Wavlink firmware (version
20201201) as this removes the webcmd console and you will need to
use the serial port instead.
You will need to have built uboot/sqauashfs image for this device,
and you will need to provide an HTTP service where the image can
be downloaded from that is accessible by the device.
You cannot use the device manufacturers firmware upgrade interface
as it rejects the OpenWrt image.
1. Log into the device's admin portal. This is necessary to
authenticate you as a user in order to be able to access the
webcmd interface.
2. Navigate to http://<device-ip>/webcmd.shtml - you can access
the console directly through this page, or you may wish to
launch the installed `telnetd` and use telnet instead.
* Using telnet is recommended since it provides a more
convenient shell interface that the web form.
* Launch telnetd from the form with the command `telnetd`.
* Check the port that telnetd is running on using
`netstat -antp|grep telnetd`, it is likely to be 2323.
* Connect to the target using `telnet`. The username should
be `admin2860`, and the password is your admin password.
3. On the target use `curl` to download the image.
e.g. `curl -L -O http://<some-other-lan-ip>/openwrt-ramips-mt7620-\
wavlink_wl-wn579x3-squashfs-sysupgrade.bin`.
Check the hash using `md5sum`.
4. Use the mtd_write command to flash the image.
* The flash partition should be mtd4, but check
/sys/class/mtd/mtd4/name first. The partition should be
called 'Kernel'.
* To flash use the following command:
`mtd_write -r -e /dev/mtd<n> write <image-file> /dev/mtd<n>`
Where mtd<n> is the Kernel partition, and <image-file> is
the OpenWrt image previously downloaded.
* The command above will erase, flash and then reboot the
device. Once it reboots it will be running OpenWrt.
Connect via ssh to the device at 192.168.1.1 on the LAN port.
The WAN port will be configured via DHCP.
Using the serial port
---------------------
The device uses uboot like many other MT7260a based boards. To
use this interface, you will need to connect to the serial
interface, and provide a TFTP server. At boot follow the
bootloader menu and select option 2 to erase/flash the image.
Provide the address and filename details for the tftp server.
The bootloader will do the rest.
Once the image is flashed, the board will boot into OpenWrt. The
console is available over the serial port.

Previous supported device YOUKU yk1 is actually Youku YK-L1. Though they look
really different, the only hardware difference between the two models is flash
size, YK-L1 has 32 MiB flash but YK-L1c has 16MiB. It seems that YK-L1c can
compatible with YK-L1's firmware but it's better to split it to different models.
It is easy to identify the models by looking at the label on the bottom of the
device. The label has the model number "YK-L1" or "YK-L1c". Due to different flash
sizes, YK-L1c that using previous YK-L1's firmware needs to apply "force update"
to install compatible firmware, so please backup config file before system upgrade.

The SERCOMM NA502 is a smart home gateway manufactured by SERCOMM and sold
under different brands (among others, A1 Telekom Austria SmartHome
Gateway). It has multi-protocol radio support in addition to LAN and WiFi.
Note: BLE is currently unsupported.
Specifications
--------------
- MT7621ST 880MHz, Single-Core, Dual-Thread
- MT7603EN 2.4GHz WiFi
- MT7662EN 5GHz WiFi + BLE
- 128MiB NAND
- 256MiB DDR3 RAM
- SD3503 ZWave Controller
- EM357 Zigbee Coordinator
MAC address assignment
----------------------
LAN MAC is read from the config partition, WiFi 2.4GHz is LAN+2 and matches
the OEM firmware. WiFi 5GHz with LAN+1 is an educated guess since the
OEM firmware does not enable 5GHz WiFi.
Installation
------------
Attach serial console, then boot the initramfs image via TFTP.
Once inside OpenWrt, run sysupgrade -n with the sysupgrade file.
Attention: The device has a dual-firmware design. We overwrite kernel2,
since kernel1 contains an automatic recovery image.

This device is very similar to the EA7300 v1/v2 and EA7500 v2.
Installation:
Upload the generated factory image through the factory web interface.
(following part taken from EA7300 v2 commit message:)
This might fail due to the A/B nature of this device. When flashing, OEM
firmware writes over the non-booted partition. If booted from 'A',
flashing over 'B' won't work. To get around this, you should flash the
OEM image over itself. This will then boot the router from 'B' and
allow you to flash OpenWRT without problems.
Reverting to factory firmware:
Hard-reset the router three times to force it to boot from 'B.' This is
where the stock firmware resides. To remove any traces of OpenWRT from
your router simply flash the OEM image at this point.

J1: pin1 (square pad, towards rear)=3.3V, pin2=RX,
pin3=GND, pin4=TX. Settings: 57600/8N1.
Note regarding dual system partitions
-------------------------------------
The vendor firmware and boot loader use a dual partition scheme. The boot
partition is decided by the bootImage U-boot environment variable: 0 for
the 1st partition, 1 for the 2nd.
OpenWrt does not support this scheme and will always use the first OS
partition. It will set bootImage to 0 during installation, making sure
the first partition is selected by the boot loader.
Also, because we can't be sure which partition is active to begin with, a
2-step flash process is used. We first flash an initramfs image, then
follow with a regular sysupgrade.
Installation:
Router (ALLY-R1900K)
1) Install the flashable initramfs image via the OEM web-interface.
(Alternatively, you can use the TFTP recovery method below.)
You can use WiFi or Ethernet.
The direct URL is: http://192.168.3.1/07_06_00_firmware.html
a. No login is needed, and you'll be in their setup wizard.
b. You might get a warning about not being connected to the Internet.
c. Towards the bottom of the page will be a section entitled "Or
Manually Upgrade Firmware from a File:" where you can manually choose
and upload a firmware file.
d: Click "Choose File", select the OpenWRT "initramfs" image and click
"Upload."
2) The Router will flash the OpenWrt initramfs image and reboot. After
booting, LuCI will be available on 192.168.1.1.
3) Log into LuCI as root; there is no password.
4) Optional (but recommended) is to backup the OEM firmware before
continuing; see process below.
5) Complete the Installation by flashing a full OpenWRT image. Note:
you may use the sysupgrade command line tool in lieu of the UI if
you prefer.
a. Choose System -> Backup/Flash Firmware.
b. Click "Flash Image..." under "Flash new firmware image"
c. Click "Browse..." and then select the sysupgrade file.
d. Click Upload to upload the sysupgrade file.
e. Important: uncheck "Keep settings and retain the current
configuration" for this initial installation.
f. Click "Continue" to flash the firmware.
g. The device will reboot and OpenWRT is installed.
Extender (ALLY-00X19K)
1) This device requires a TFTP recovery procedure to do an initial load
of OpenWRT. Start by configuring a computer as a TFTP client:
a. Install a TFTP client (server not necessary)
b. Configure an Ethernet interface to 192.168.1.x/24; don't use .1 or .6
c. Connect the Ethernet to the sole Ethernet port on the X19K.
2) Put the ALLY Extender in TFTP recovery mode.
a. Do this by pressing and holding the reset button on the bottom while
connecting the power.
b. As soon as the LED lights up green (roughly 2-3 seconds), release
the button.
3) Start the TFTP transfer of the Initramfs image from your setup machine.
For example, from Linux:
tftp -v -m binary 192.168.1.6 69 -c put initramfs.bin
4) The Extender will flash the OpenWrt initramfs image and reboot. After
booting, LuCI will be available on 192.168.1.1.
5) Log into LuCI as root; there is no password.
6) Optional (but recommended) is to backup the OEM firmware before
continuing; see process below.
7) Complete the Installation by flashing a full OpenWRT image. Note: you
may use the sysupgrade command line tool in lieu of the UI if you prefer.
a. Choose System -> Backup/Flash Firmware.
b. Click "Flash Image..." under "Flash new firmware image"
c. Click "Browse..." and then select the sysupgrade file.
d. Click Upload to upload the sysupgrade file.
e. Important: uncheck "Keep settings and retain the current
configuration" for this initial installation.
f. Click "Continue" to flash the firmware.
g. The device will reboot and OpenWRT is installed.
Backup the OEM Firmware:
-----------------------
There isn't any downloadable firmware for the ALLY devices on the Amped
Wireless web site. Reverting back to the OEM firmware is not possible
unless we have a backup of the original OEM firmware.
The OEM firmware may be stored on either /dev/mtd3 ("firmware") or
/dev/mtd6 ("oem"). We can't be sure which was overwritten with the
initramfs image, so backup both partitions to be safe.
1) Once logged into LuCI, navigate to System -> Backup/Flash Firmware.
2) Under "Save mtdblock contents," first select "firmware" and click
"Save mtdblock" to download the image.
3) Repeat the process, but select "oem" from the pull-down menu.
Revert to the OEM Firmware:
--------------------------
* U-boot TFTP:
Follow the TFTP recovery steps for the Extender, and use the
backup image.
* OpenWrt "Flash Firmware" interface:
Upload the backup image and select "Force update"
before continuing.

Installation:
------------
Install the OpenWrt factory image for C6U is from the
TP-Link web interface.
1) Go to "Advanced/System Tools/Firmware Update".
2) Click "Browse" and upload the OpenWrt factory image:
openwrt-ramips-mt7621-tplink_archer-c6u-v1-squashfs-factory.bin.
3) Click the "Upgrade" button, and select "Yes" when prompted.
Recovery to stock firmware:
--------------------------
The C6U bootloader has a failsafe mode that provides a web
interface (running at 192.168.0.1) for reverting back to the
stock TP-Link firmware. The failsafe interface is triggered
from the serial console or on failed kernel boot. Unfortunately,
there's no key combination that enables the failsafe mode. This
gives us two options for recovery:
1) Recover using the serial console (J1 header).
The recovery interface can be selected by hitting 'x' when
prompted on boot.
2) Trigger the bootloader failsafe mode.
A more dangerous option is force the bootloader into
recovery mode by erasing the OpenWrt partition from the
OpenWrt's shell - e.g "mtd erase firmware". Please be
careful, since erasing the wrong partition can brick
your device.

image at 10.10.10.3
- Type "ATNR 1,initramfs-recovery.bin" at the "ZLB>" prompt
- Wait for OpenWrt to boot and ssh to root@192.168.1.1
- Sysupgrade to the OpenWrt sysupgrade image
NOTE: ATNR will write the recovery image to both primary and recovery
partitions in one go.
Booting from RAM:
- Halt boot by pressing Escape on console
- Type "ATGU" at the "ZLB>" prompt to enter the U-Boot menu
- Press "4" to select "4: Entr boot command line interface."
- Set up a tftp server to serve the OpenWrt initramfs-recovery.bin
image at 10.10.10.3
- Load it using "tftpboot 0x88000000 initramfs-recovery.bin"
- Boot with "bootm 0x8800017C" to skip the 380 (0x17C) bytes ZyXEL
header
This method can also be used to RAM boot OEM firmware. The warning
regarding OEM applies! Never boot an unknown OEM firmware, or any OEM
firmware with a SIM in any slot.
NOTE: U-Boot configuration is incomplete (on some devices?). You may
have to configure a working mac address before running tftp using
"setenv eth0addr <mac>"
Unlocking the bootloader:
If you are unebale to halt boot, then the bootloader is locked.
The OEM firmware locks the bootloader on every boot by setting
DebugFlag to 0. Setting it to 1 is therefore only temporary
when OEM firmware is installed.
- Run "nvram setro uboot DebugFlag 0x1; nvram commit" in OEM firmware
- Run "fw_setenv DebugFlag 0x1" in OpenWrt
NOTE:
OpenWrt does this automatically on first boot if necessary
NOTE2:
Setting the flag to 0x1 avoids the reset to 0 in known OEM
versions, but this might change.
WARNING:
Writing anything to flash while the bootloader is locked is
considered extremely risky. Errors might cause a permanent
brick!
Enabling management access from LAN:
Temporary workaround to allow installing OpenWrt if OEM firmware
has disabled LAN management:
- Connect to console
- Log in as "root"
- Run "iptables -I INPUT -i br0 -j ACCEPT"
Notes on the OEM/bootloader dual partition scheme
The dual partition scheme on this device uses Image2 as a recovery
image only. The device will always boot from Image1, but the
bootloader might copy Image2 to Image1 under specific conditions. This
scheme prevents repurposing of the space occupied by Image2 in any
useful way.
Validation of primary and recovery images is controlled by the
variables CheckBypass, Image1Stable, and Image1Try.
The bootloader sets CheckBypass to 0 and reboots if Image1 fails
validation.
If CheckBypass is 0 and Image1 is invalid then Image2 is copied to
Image1.
If CheckBypass is 0 and Image2 is invalid, then Image1 is copied to
Image2.
If CheckBypass is 1 then all tests are skipped and Image1 is booted
unconditionally. CheckBypass is set to 1 after each successful
validation of Image1.
Image1Try is incremented if Image1Stable is 0, and Image2 is copied to
Image1 if Image1Try is 3 or larger. But the bootloader only tests
Image1Try if CheckBypass is 0, which is impossible unless the booted
image sets it to 0 before failing.
The system is therefore not resilient against runtime errors like
failure to mount the rootfs, unless the kernel image sets CheckBypass
to 0 before failing. This is not yet implemented in OpenWrt.
Setting Image1Stable to 1 prevents the bootloader from updating
Image1Try on every boot, saving unnecessary writes to the environment
partition.
Keeping an OpenWrt initramfs recovery as Image2 is recommended
primarily to avoid unwanted OEM firmware boots on failure. Ref the
warning above. It enables console-less recovery in case of some
failures to boot from Image1.
