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.

Power: 802.11af/at PoE; DC 12V,1A
Antennas: AX820(indoor): 4dBi internal; HWAP-AX820(outdoor): external
Flash instructions:
The "OpenWRT support" version of the AX820 comes with a LEDE-based
firmware with proprietary MTK drivers and a luci webinterface and
ssh accessible under 192.168.1.1 on LAN; user root, no password.
The sysupgrade.bin can be flashed using luci or sysupgrade via ssh,
you will have to force the upgrade due to a different factory name.
Remember: Do *not* preserve factory configuration!
MAC addresses as used by OEM firmware:
use address source
2g 44:D1:FA:*:0b Factory 0x0004 (label)
5g 46:D1:FA:*:0b LAA of 2g
lan 44:D1:FA:*:0c Factory 0xe000
wan 44:D1:FA:*:0d Factory 0xe000 + 1
The wan MAC can also be found in 0xe006 but is not used by OEM dtb.
Due to different MAC handling in mt76 the LAA derived from lan is used
for 2g to prevent duplicate MACs when creating multiple interfaces.

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.

Previously, grub2 was hardcoded to always look on "hd0" for the
kernel.
This works well when the system only had a single disk.
But if there was a second disk/stick present, it may have look
on the wrong drive because of enumeration races.
This patch utilizes grub2 search function to look for a filesystem
with the label "kernel". This works thanks to existing setup in
scripts/gen_image_generic.sh. Which sets the "kernel" label on
both the fat and ext4 filesystem variants.

At least since gcc 7.3.0 (OpenWrt 18.06) lwr/lwl are used in the
assembly of LzmaProps_Decode. While the decission made by the compiler
looks perfect fine, it triggers some obscure hang on lantiq danube-s
v1.5 with MX29LV640EB NOR flash chips.
Only if the offset 1 is used, the hang can be observed. Using any other
offset works fine:
lwl s0,0(a1) - s0 == 0x6d000080
lwl s0,1(a1) - hangs
lwl s0,2(a1) - s0 == 0x0080xxxx
lwl s0,3(a1) - s0 == 0x80xxxxxx
It isn't clear whether it is a limitation of the flash chip, the EBU or
something else.
Force 8bit reads to prevent gcc optimizing the read with lwr/lwl
instructions.

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.

nearly identical, except the Extender lacks a USB port and has a single
Ethernet port.
Specification:
- SoC: MediaTek MT7621AT (2C/4T) @ 880MHz
- RAM: 128MB DDR3 (Nanya NT5CC64M16GP-DI)
- FLASH: 128MB NAND (Winbond W29N01GVSIAA)

- UART: through-hole on PCB.
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.

WARNING!!
ISP managed firmware might at any time update itself to a version
where all known workarounds have been disabled. Never boot an ISP
managed firmware with a SIM in any of the slots if you intend to use
the router with OpenWrt. The bootloader lock can only be disabled with
root access to running firmware. The flash chip is physically
inaccessible without soldering.
Installation from OEM web GUI:
- Log in as "supervisor" on https://172.17.1.1/
- Upload OpenWrt initramfs-recovery.bin image on the
Maintenance -> Firmware page
- Wait for OpenWrt to boot and ssh to root@192.168.1.1
- (optional) Copy OpenWrt to the recovery partition. See below
- Sysupgrade to the OpenWrt sysupgrade image and reboot
Installation from OEM ssh:
- Log in as "root" on 172.17.1.1 port 22022
- scp OpenWrt initramfs-recovery.bin image to 172.17.1.1:/tmp
- Prepare bootloader config by running:
nvram setro uboot DebugFlag 0x1
nvram setro uboot CheckBypass 0
nvram commit
- Run "mtd_write -w write initramfs-recovery.bin Kernel" and reboot
- Wait for OpenWrt to boot and ssh to root@192.168.1.1
- (optional) Copy OpenWrt to the recovery partition. See below
- Sysupgrade to the OpenWrt sysupgrade image and reboot
Copying OpenWrt to the recovery partition:
- Verify that you are running a working OpenWrt recovery image
from flash
- ssh to root@192.168.1.1 and run:
fw_setenv CheckBypass 0
mtd -r erase Kernel2
- Wait while the bootloader mirrors Image1 to Image2
NOTE: This should only be done after successfully booting the OpenWrt
recovery image from the primary partition during installation. Do
not do this after having sysupgraded OpenWrt! Reinstalling the
recovery image on normal upgrades is not required or recommended.
Installation from Z-Loader:
- Halt boot by pressing Escape on console
- Set up a tftp server to serve the OpenWrt initramfs-recovery.bin
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.
