TP-Link RE650 v2 is largely similar to v1 that
is already supported by OpenWrt. Notable differences
is differnt SPI Flash - 8 MB instead of 16 MB
(from cFeon instead of Winbond) and a different
configuration of PCIE connections to wifi chips.
Otherwise it's largely the same product as v1
Hardware specification:
- SoC 880 MHz - MediaTek MT7621AT
- 128 MB of DDR3 RAM
- 8 MB - cFeon QH64A-104HIP
- 4T4R 2.4 GHz - MediaTek MT7615E
- 4T4R 5 GHz - MediaTek MT7615E
- 1x 1 Gbps Ethernet - MT7621AT integrated
- 7x LEDs (Power, 2G, 5G, WPS(x2), Lan(x2))
- 4x buttons (Reset, Power, WPS, LED)
- UART pinout - GND, RX, TX, labeled in the middle of the PCB,
requires soldering because they're not through holes.

TFTP recovery to stock firmware:
I didn't try recovering back to the stock firmware, however,
if there is such process for other RExxx devices, it seems like
it could be similar here.

OrayBox X3A is a 2.4/5GHz dual band AC router, based on MediaTek MT7621.
Specification:
* SoC: MT7621
* RAM: DDR3 128 MiB
* Flash: 16 MiB NOR (XM25Q128)
* Wi-Fi: (single chip hosting both 2.4G and 5G)
* 2.4GHz: MT7615
* 5GHz: MT7615
* Ethernet: 3x 1000Mbps
* Switch: MT7530
* LED:
* Ethernet LEDs: On the back of the router, hardware-controlled.
* Status LEDs: One "pixel-like" RGB LED in the front of the router,
which is actually made up of 3 individual LEDs (with
dedicated GPIO pins) with the color of Red, Green,
and Blue.
The OEM firmware only lights up one color at a time to
indicate status, but that's very boring, and the colors
actually look great when combined, so I've improvised a
little and made them indicate netdev activities.
My test results:
GPIO 13/14/15
000 white (actually more like bright green or cyan
because the brightness of the green LED is
higher than red and blue)
001 bright purple
010 bright green
011 red
100 bright cyan
101 blue
110 green
111 off

Installation via SSH (does not void your warranty):
1. -----UNLOCK SSH-----
1.1 Set computer IP to DHCP mode, load 'http://10.168.1.1/cgi-bin/luci' in
your browser. Password is 'admin'.
1.2 Click the "备份且导出" (backup and export) button, and download the
config file.
1.3 Open the downloaded file with 7zip, navigate to '/etc/config/'.
1.4 Edit the file './system'. Change the '0' into '1' under
"config sys 'ssh'".
1.5 Save the file.
1.6 Upload the file by clicking the "导入且恢复" (import and recover)
button. The router will automatically reboot.
2. -----FLASH THE OPENWRT FIRMWARE-----
2.1 Use any scp tool to upload the 'sysupgrade' firmware to the '/tmp/'
folder to your router. It should be root@10.168.1.1 and the password
is 'admin'.
2.2 SSH into the router, also root@10.168.1.1 and the password is 'admin'.
2.3 **IMPORTANT** Type command 'dd if=/dev/mtd3 of=/tmp/firmware.bin', to
backup the stock firmware. Since the OEM does not provide firmware
download on their website, this is the only way to get it.
2.3 **ALSO IMPORTANT** Use any scp tool to download your backed-up stock
firmware from '/tmp/' to your local drive. Then you'd better use a hex
reading tool to have a rough look at it to make sure nothing is
corrupt. Or u can just back up again and cross check the MD5.
2.4 Type command 'mtd write /tmp/XXX.bin firmware', and it should flash
the firmware.
2.5 Verify that nothing went wrong. If you're confident, type 'reboot' and
reboot the router.
Revert to stock firmware:
1. load stock firmware using mtd (make sure u have a backup).

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.

This is another MT7621 device, very similar to other Linksys EA7300
series devices.
Installation:
Upload the generated factory.bin image via the stock web firmware
updater.
Reverting to factory firmware:
Like other EA7300 devices, this device has an A/B router configuration
to prevent bricking. Hard-resetting this device three (3) times will
put the device in failsafe (default) mode. At this point, flash the
OEM image to itself and reboot. This puts the router back into the 'B'
image and allows for a firmware upgrade.
Troubleshooting:
If the firmware will not boot, first restore the factory as described
above. This will then allow the factory.bin update to be applied
properly.

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.

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'

Installation:

(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.

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.

This device has 2 partitions for the firmware called firmware and
alt_firmware. To successfully flash and boot the device, the device
should have been running from alt_firmware partition. To get the device
booted through alt_firmware partition, download the OEM firmware from
Linksys website and upgrade the firmware from web GUI. Once this is done,
flash the OpenWrt Factory firmware from web GUI.
Reverting to factory firmware:
1. Boot to 'alt_firmware'(where stock firmware resides) by doing one of
the following:
Press the "wps" button as soon as power LED turns on when booting.
(OR) Hard-reset the router consecutively three times to force it to
boot from 'alt_firmware'.

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.

[fix device definition title]
Signed-off-by: Adrian Schmutzler <freifunk@adrianschmutzler.de>
While we mostly use the ucidef_set_led_* functions directly in 01_leds
we still have the set_wifi_led function in parallel for several old
devices. This is not only inconsistent with the other definitions,
it also links to the wlan0 interface instead of using a phy trigger
which would be independent of the interface name (and is used for
all newer devices anyway). Apart from that, the standard names
"wifi" and "wifi-led" are not very helpful in a world with different
radio bands either.
Thus, this patch removes the set_wifi_led function and puts the
relevant commands into the cases explicitly. This makes the
mechanism used more evident and will hopefully lead to some future
improvements or at least prevent some copy-pasting of the old
setups.

In ramips, it's not common to use an alias for specifying the WiFi
LED; actually only one device uses this mechanism (TL-WR841N v14).
Particularly since the WiFi LEDs are typically distinguished between
2.4G and 5G etc. it is also not very useful for this target.
Thus, this patch removes the setup lines for this mechanism and
converts the TL-WR841N v14 to the normal setup.

Like in the previous patch for ath79 target, this will remove the
"devicename" from LED labels in ramips as well.
The devicename is removed in DTS files and 01_leds, consolidation
of definitions into DTSI files is done where (easily) possible,
and migration scripts are updated.
For the latter, all existing definitions were actually just
devicename migrations anyway. Therefore, those are removed and
a common migration file is created in target base-files. This is
actually another example of how the devicename removal makes things
easier.

To boot to intramfs image in RAM:
1. Setup TFTP server to serve intramfs image.
2. Plug Ethernet cable into WAN port.
3. Unplug power, hold reset button and plug power in.
Wait (~25 seconds) for beep and then release reset button.
The SFP LED will be lit in RouterBoot, but will not be lit in OpenWRT.
4. Wait for a minute. Router should be running OpenWrt,
check by plugging in to port 2-5 and going to 192.168.1.1.
To install OpenWrt to flash:
1. Follow steps above to boot intramfs image in RAM.
2. Flash the sysupgrade.bin image with web interface or sysupgrade.
3. Once the router reboots you will be running OpenWrt from flash.

- RouterOS assigns a different MAC address for each port
- The first address (E01 on the sticker) is used for wan (ether1 in OEM).
- The next address is used for lan2.
- The last address (E06 on the sticker) is used for sfp.
