The RavPower WD03 is a battery powered SD card reader and a USB port.
Specifications:
SOC: MediaTek MT7620N
BATTERY: 6000mah
WLAN: 802.11bgn
LAN: 1x 10/100 Mbps Ethernet
USB: 1x USB 2.0 (Type-A)
RAM: PM Tech PMD708416CTR-5CN 32 MB
FLASH: Holtek HT66F40 - 8 MB Flash
LED: Power button and 4 leds to indicate power level of the
battery (could not get control of that)
INPUT: Power, reset button
OTHER: USB SD-Card reader with card detect on GPIO#42
Tested and working:
- Ethernet
- 2.4 GHz WiFi (Correct MAC-address)
- installation from tftp
- OpenWRT sysupgrade (Preserving and non-preserving)
- LEDs
- Buttons
Installation:
- Download the sysupgrade image
- Place it in the root of a clean TFTP server running on your computer.
- Rename the image to "kernel" — be sure there is no file extension.
- Plug the WD03 into your computer via ethernet.
- Set your computer to use 10.10.10.254 as its IP address.
- With your WD03 shut down, hold down the power button until the first
white LED lights up.
- Push and hold the reset button and release the power button. Continue
holding the reset button for 30 seconds or until it begins searching
for files on your TFTP server, whichever comes first.
- The WD03 (10.10.10.128) will look for your computer at 10.10.10.254
and install the kernel file. Once it has finished installation of the
kernel file, it will search for a (nonexistent) rootfs file — when it
begins searching for this file, shut down the WD03 by holding the
power button normally.
- Start up your WD03 normally.

- 5200 mAh battery
The ramdisk image (not the squashfs sysupgrade image) can be flashed
through the web interface (named "GoAhead") of the factory firmware.
However, as the factory firmware does not cleanly unmount the rootfs
before flashing, the device may hang instead of rebooting after
successful write. Power cycling the device gets you in OpenWrt where
the squashfs image may be flashed through normal sysupgrade procedure.

The previous fw version require the replacement of the stock bootloader
with u-boot. This prevent an easy stock restore of the original fw.
Now a proper fw util has been developed to manage the stock jboot
bootloader. Therefore make sense have a fw image for the stock
bootloader.
The old fw configuration (u-boot) is not compatible with the new one
and will not be supported anymore.
So at the end 2 image can be generated:
1) factory image with jboot bootloader
openwrt-ramips-rt305x-dwr-512-b-squashfs-factory.bin
2) sysupgrade image with jboot bootloader

Errata:
- While there are three ethernet ports, the third requires support for
the second GMAC. This will come in kernel 4.14.
- The first hard drive slot has a clearance issue with the two fan

jumper wires.
- Using this device as a NAS is problematic with the 4.9 kernel as many
/dev/sdX reads throw silent errors. The current theory behind this is
some kind of unhandled DMA mapping error in the kernel. This is not an

The VAR11N-300 is a tiny wireless-N device with a hardwired Ethernet
cable, one extra Ethernet port, and an internal antenna, based on the
MediaTek MT7620n chipset.
Specs:
- MT7620n WiSoC @ 600MHz
- 32 MB SDRAM
- 4 MB SPI flash
- 2T2R 2.4GHz WiFi-N
- 1 attached 10/100 Ethernet cable (LAN)
- 1 10/100 Ethernet port (WAN)
- 1 attached USB / barrel 5vdc power cable
- 5 LEDs (see notes below)
- 1 reset button
- 1 UART (3 pads on board)
Installation:
The stock firmware does not support uploading new firmware directly,
only checking the manufacturer's site for updates. This process may be
possible to spoof, but the update check uses some kind of homebrew
encryption that I didn't investigate. Instead, you can install via a
backdoor:
1. Set up a TFTP server to serve the firmware binary
(lede-ramips-mt7620-var11n-300-squashfs-sysupgrade.bin)
2. Factory reset the device by holding the reset button for a few
seconds.
3. Open the web interface (default IP: 192.168.253.254)
4. Log in with the "super admin" credentials: username `vonets`,
password `vonets26642519`.
5. On the "Operative Status" page, click the text "System Uptime", then
quickly click the uptime value.
6. If successful, an alert dialog will appear reading "Ated start", and
the device will now accept telnet connections. If the alert does not
appear, repeat step 5 until it works (the timing is a bit tricky).
7. Telnet to the device using credentials "admin / admin"
8. Retrieve the firmware binary from the tftp server: `tftp -l lede.bin
-r lede-ramips-mt7620-var11n-300-squashfs-sysupgrade.bin -g
<tftp-server-ip>`
9. Write the firmware to flash: `mtd_write write lede.bin /dev/mtd4`
10. Reboot
Tested:
- LAN / WAN ethernet
- WiFi
- LAN / WAN / status LED GPIOs (see notes below)
- Reset button
- Sysupgrade
Notes:
LEDs:
The board has 5 LEDs - two green LEDs for LAN / WAN activity, one blue
LED for WiFi, and a pair of "status" LEDs connected to the same GPIO
(the blue LED lights when the GPIO is low, and the green when it's
high). I was unable to determine how to operate the WiFi LED, as it
does not appear to be controlled by a GPIO directly.
Recovery:
The default U-boot installation will only boot from flash due to a
missing environment block. I generated a valid 4KB env block using
U-boot's `fw_setenv` tool and wrote it to flash at 0x30000 using an
external programmer. After this, it was possible to enter the U-boot
commandline interface and download a new image via TFTP (`tftpboot
81b00000 <image-filename>`), but while I could boot this image
sucessfully (`bootm`), writing it to flash (`cp.linux`) just corrupted
the flash chip. The sysupgrade file can be written to flash at 0x50000
using an external programmer.

The following has been tested and is working:
- Ethernet switch
- miniPCIe slot (tested with modem and Wi-Fi card)
- miniSIM slot
- sysupgrade
- reset button
- USB 2.0 port*
Due to a missing driver (MMC over GPIO) this is not supported:
- microSD card reader
* Warning:
USB buses in miniPCIe and regular A-type socket are connected together,
without any proper analog switch or USB HUB.
Installation:
This board might come with a different firmware versions (MediaTek SDK,
PandoraBox, Padavan, etc.). If your board comes with PandoraBox, you can
install LEDE using sysupgrade. Just SSH to the router and perform forced
sysupgrade (due to a board name mismatch). The default IP of this board
should be: 192.168.1.1 and username/password: root/admin. In case of a
different firmware, you can use web based recovery described below.
Use the following command to perform the sysupgrade (for the 128MB
RAM/16MB flash version):
sysupgrade -n -F lede-ramips-mt76x8-u7628-01-128M-16M-squashfs-sysupgrade.bin
Recovery:
This board contains a Chinese, closed-source bootloader called Breed
(Boot and Recovery Environment for Embedded Devices). Breed supports web
recovery and to enter it, you keep the reset button pressed for around
5 seconds during boot. Your machine will be assigned an IP through DHCP
and the router will use IP address 192.168.1.1. The recovery website is
in Chinese, but is easy to use. Click on the second item in the list to
access the recovery page, then the second item on the next page is where
you select the firmware. In order to start the recovery, you click the
button at the bottom.
SDXC/GPIO header (J3):
1. SDXC_D3 / I2C_SCLK
2. SDXC_D2 / I2C_SD
3. SDXC_D1 / I2S_DI
4. SDXC_D0 / I2S_WS
5. SDXC_CMD / I2S_CLK
6. SDXC_CLK / GPIO0
7. SDXC_CD / UART_RXD1
8. UART_TXD1
9. 3V3
10. GND
Other notes:
1. The board is available with different amounts of RAM and flash. We
have only added support for the 128/16 MB configuration, as that seems
to be the default. However, all the required infrastructure is in place
for making support for the other configurations easy.

2. The manufacturer offers five different wireless cards with MediaTek
chipsets, based on MT76x2, MT7603 and MT7615. Images of the board all
show that the miniPCIe slots are dedicated to specific Wi-Fi cards.
However, the slots are generic.
3. All boards we got access to had the same EEPROM content. The default
firmware reads the Ethernet MAC from offset 0xe000 in factory partition.
This offset only contains 0xffs, so a random MAC will be generated on
every boot of the router. There is a valid MAC stored at offset 0xe006
and this MAC is shown as the WAN MAC in the bootloader. However, it is
the same on all boards we have checked. Based on information provided
by the vendor, all boards sold in small quantities are considered more
as samples for development purposes.

TP-Link TL-WR840N v5 is simple N300 router with 5-port FE switch and
non-detachable antennas, based on MediaTek MT7628NN (aka MT7628N) WiSoC.
Specification:
- MT7628N/N (580 MHz)
- 64 MB of RAM (DDR2)
- 4 MB of FLASH
- 2T2R 2.4 GHz
- 5x 10/100 Mbps Ethernet
- 2x external, non-detachable antennas
- UART (J1) header on PCB (115200 8n1)
- 1x LED (GPIO-controlled), 1x button
* LED in TL-WR840N v5 is a dual-color, dual-leads type which isn't
(fully) supported by gpio-leds driver. This type of LED requires both
GPIOs state change at the same time to select color or turn it off.
For now, we support/use only the green part of the LED.
Orange LED is registered so you can later use it for your own purposes.
Flash instruction:
Unlike TL-WR840N v4 flashing through WEB UI works in v5.
1. Download lede-ramips-mt76x8-tl-wr840n-v5-squashfs-sysupgrade.bin image.
2. Go to 192.168.0.1
3. Flash the sysupgrade image through Firmware upgrade section of WEB UI.
4. Wait until green LED stops flashing and use the router.
Notes:
TFTP recovery is broken since TP-Link reused bootloader code for v4 and
that does not take into account only 4 MB of flash and bricks the device.
So do not use TFTP Recovery or you will have to rewrite SPI flash.
They fixed it in later GPL code,but it is unknown which version of
bootloader you have.
After manually compiling and flashing bootloader from GPL sources TFTP
recovery works properly.

TP-Link Archer C20 v1 is a router with 5-port FE switch and
non-detachable antennas. It's very similiar to TP-Link Archer C50.
Also it's based on MediaTek MT7620A+MT7610EN.
Specification:
- MediaTek MT7620A (580 Mhz)
- 64 MB of RAM
- 8 MB of FLASH
- 2T2R 2.4 GHz and 1T1R 5 GHz
- 5x 10/100 Mbps Ethernet
- 2x external, non-detachable antennas
- UART (J1) header on PCB (115200 8n1)
- 8x LED (GPIO-controlled*), 2x button, power input switch
- 1 x USB 2.0 port
* WAN LED in this devices is a dual-color, dual-leads type which isn't
(fully) supported by gpio-leds driver. This type of LED requires both
GPIOs state change at the same time to select color or turn it off.
For now, we support/use only the blue part of the LED.
* MT7610EN ac chip isn't not supported by LEDE. Therefore 5Ghz won't
work.
Factory image notes:
These devices use version 3 of TP-Link header, fortunately without RSA
signature (at least in case of devices sold in Europe). The difference
lays in the requirement for a non-zero value in "Additional Hardware
Version" field. Ideally, it should match the value stored in vendor
firmware header on device.
We are able to prepare factory firwmare file which is accepted and
(almost) correctly flashed from the vendor GUI. As it turned out, it
accepts files without U-Boot image with second header at the beginning
but due to some kind of bug in upgrade routine, flashed image gets
corrupted before it's written to flash. So, to flash this device we must
to prepare image using original firmware from tp-link site with uboot.
Flash instruction:
Until (if at all) TP-Link fixes described problem, the only way to flash
LEDE image in these devices is to use tftp recovery mode in U-Boot.
There are two ways to flash the device to LEDE:
1) Using tftp mode with UART connection and original LEDE image
- Place lede-ramips-mt7620-ArcherC20-squashfs-factory.bin in tftp
server directory
- Configure PC with static IP 192.168.0.66/24 and tftp server.
- Connect PC with one of LAN ports, power up the router and press
key "4" to access U-Boot CLI.
- Use the following commands to update the device to LEDE:
setenv serverip 192.168.0.66
tftp 0x80060000 lede-ramips-mt7620-ArcherC20-squashfs-factory.bin
erase tplink 0x20000 0x7a0000
cp.b 0x80060000 0x20000 0x7a0000
reset
- After that the device will reboot and boot to LEDE
2) Using tftp mode without UART connection but require some
manipulations with target image
- Download and unpack TP-Link Archer C20 v1 firmware from original web
site
- Split uboot.bin from original firmware by this command (example):
dd if=Archer_C20v1_0.9.1_4.0_up_boot(160427)_2016-04-27_13.53.59.bin of=uboot.bin bs=512 count=256 skip=1
- Create ArcherC20V1_tp_recovery.bin using this command:
cat uboot.bin lede-ramips-mt7620-ArcherC20-squashfs-factory.bin > ArcherC20V1_tp_recovery.bin
- Place ArcherC20V1_tp_recovery.bin in tftp server directory.
- Configure PC with static IP 192.168.0.66/24 and tftp server.
- Connect PC with one of LAN ports, press the reset button, power up
the router and keep button pressed for around 6-7 seconds, until
device starts downloading the file.
- Router will download file from server, write it to flash and reboot.

The ZBT WE1026-5G
(http://www.zbtlink.com/products/router/WE1026-5G.html) is the follow-up
to the ZBT WE1026 and is based on MT7620. For the previous WE1026, the
ZBT WE826 image could be used. However, as the name implies, the -5G
comes equipped with a 5GHz wifi radio. As the WE826 only has a 2.4GHz
radio, the addition of 5GHz means that a separate image is needed for
the WE1026-5G. I suspect that this image will also work on the previous
WE1026, but I don't have a device to test with.
The WE1026-5G has following specifications:
* CPU: MT7620A
* 1x 10/100Mbps Ethernet.
* 16 MB Flash.
* 64 MB RAM.
* 1x USB 2.0 port.
* 1x mini-PCIe slots.
* 1x SIM slots.
* 1x 2.4Ghz WIFI.
* 1x 5GHz wifi (MT7612)
* 1x button.
* 3x controllable LEDs.
Works:
* Wifi.
* Switch.
* mini-PCIe slot. Only tested with a USB device (a modem).
* SIM slot.
* Sysupgrade.
* Button (reset).
Not working:
* The 5GHz WIFI LED is completely dead. I suspect the issue is the same
as on other devices with Mediatek 5Ghz wifi-cards/chips. The LED is
controlled by the driver, and mt76 (currently) does not support this.
Not tested:
* SD card reader.
Notes:
* The modem (labeled 3G/4G) and power LEDs are controlled by the
hardware.
* There is a 32MB version of this device available, but I do not have
access to it. I have therefor only added support for the 16MB version,
but added all the required infrastructure to make adding support for the
32MB version easy.
Installation:
The router comes pre-installed with OpenWRT, including a variant of
Luci. The initial firmware install can be done through this UI,
following normal procedure. I.e., access the UI and update the firmware
using the sysupgrade-image. Remember to select that you do not want to
keep existing settings.
Recovery:
If you brick the device, the WE1026-5G supports recovery using HTTP. Keep the
reset button pressed for ~5sec when booting to start the web server. Set the
address of the network interface on your machine to 192.168.1.2/24, and
point your browser to 192.168.1.1 to access the recovery UI. From the
recovery UI you can upload a firmware image.

- 256MB DDR3 RAM
- 128MB NAND flash
- 1+2 x 1000M Ethernet
- 1x USB 3.0 port
- reset button
- yellow, blue, red leds
Installation through telnet/ssh:
- copy lede-ramips-mt7621-mir3g-squashfs-kernel1.bin and
lede-ramips-mt7621-mir3g-squashfs-rootfs0.bin to usb disk or wget it
from LEDE download site to /tmp
- switch to /extdisks/sda1/ (if copied to USB drive) or to /tmp if
wgetted from LEDE download site
- run: mtd write lede-ramips-mt7621-mir3g-squashfs-kernel1.bin kernel1
- run: mtd write lede-ramips-mt7621-mir3g-squashfs-rootfs0.bin rootfs0
- run: mtd erase kernel0
- run: reboot
Originally stock firmware has following partitions:
- ...
- kernel0 (primary kernel image)
- kernel1 (secondary kernel image, used by u-boot in failsafe routine)
- rootfs0 (primary rootfs)
- rootfs1 (secondary rootfs in case primary fails)
- overlay (used as ubi overlay)
This commit squashes rootfs0, rootfs1 and overlay partitions into 1, so
it can be used by LEDE fully for package installation, resulting in 117,5MiB.
This device lacks hw watchdog, so adding softdog instead (stock does the same).

The WMDR-143N is a small module originally used as a Wifi client
in some Loewe smart TV sets. It is sold cheaply at german surplus
shops. The module contains a RT3662 SOC.
Specifications:
- 500 MHz CPU Clock
- 1x 10/100Mbps Ethernet (pin header)
- 32 MB of RAM
- 8 MB of FLASH
- 2T3R 2.4/5 GHz (SOC internal)
- 3 Antennas on PCB
- UART pads on PCB (J3: 1 = +3.3V, 2 = RX, 3 = TX, 4 = GND), TX
and RX are 3,3V only! The square hole is pin 1
- Power supply pads on PCB (J6: 1 and 2 = +5V, 3 and 4 = GND)
The square hole is pin 1
The original firmware has two identical kernel/rootfs images and
two "Factory" calibration data blocks in flash. The LEDE image
leaves only the first "Factory" block in place and uses both
"Kernel" blocks and the redundant "Factory" block together to gain
enough space for the jffs2 partition.
Flash instructions:
You need UART and Ethernet connections to flash the board. Use
the LEDE "sysupgrade.bin" image with tftp.
Apply power to the board and in the first 5 seconds, hit 2 to
select TFTP upload. The bootloader asks for board- and server IP
addresses and filename.
Alternate method: With the vendor firmware running, assign an IP
address to the ethernet port, tftp the firmware image to
/tmp and write to mtd4 ("KernelA").

It uses one MT7615D radio chip with DBDC mode enabled. This mode allows
this single chip act as an 2x2 11n radio and an 2x2 11ac radio at the
same time. However mt76 doesn't support it currently so there is no
wireless available.
Specification:
- SoC: MediaTek MT7621AT
- Flash: 16 MB
- RAM: 128 MB
- Ethernet: 1 x WAN (10/100/1000Mbps) and 4 x LAN (10/100/1000 Mbps)
- Wireless radio: MT7615D on PCIE0
- UART: 1 x UART on PCB - 57600 8N1
Issue:
- Wireless radio doesn't work due to the lack of driver.
Flash instruction:
Using UART:
1. Configure PC with a static IP address and setup an TFTP server.
2. Put the firmware into the tftp directory.
3. Connect the UART line as described on the PCB.
4. Power up the device and press 2,then follow the instruction to
set device and tftp server IP address and input the firmware
file name.U-boot will then load the firmware and write it into
the flash.

TP-Link TL-WR840N v4 and TL-WR841N v13 are simple N300 routers with
5-port FE switch and non-detachable antennas. Both are very similar
and are based on MediaTek MT7628NN (aka MT7628N) WiSoC.
The difference between these two models is in number of available
LEDs, buttons and power input switch.
This work is partially based on GitHub PR#974.
Specification:
- MT7628N/N (580 MHz)
- 64 MB of RAM (DDR2)
- 8 MB of FLASH
- 2T2R 2.4 GHz
- 5x 10/100 Mbps Ethernet
- 2x external, non-detachable antennas
- UART (J1) header on PCB (115200 8n1)
- TL-WR840N v4: 5x LED (GPIO-controlled), 1x button
- TL-WR841N v13: 8x LED (GPIO-controlled*), 2x button, power input
switch
* WAN LED in TL-WR841N v13 is a dual-color, dual-leads type which isn't
(fully) supported by gpio-leds driver. This type of LED requires both
GPIOs state change at the same time to select color or turn it off.
For now, we support/use only the green part of the LED.
Factory image notes:
These devices use version 3 of TP-Link header, fortunately without RSA
signature (at least in case of devices sold in Europe). The difference
lays in the requirement for a non-zero value in "Additional Hardware
Version" field. Ideally, it should match the value stored in vendor
firmware header on device ("0x4"/"0x13" for these devices) but it seems
that anything other than "0" is correct.
We are able to prepare factory firwmare file which is accepted and
(almost) correctly flashed from the vendor GUI. As it turned out, it
accepts files without U-Boot image with second header at the beginning
but due to some kind of bug in upgrade routine, flashed image gets
corrupted before it's written to flash.
Tests showed that the GUI upgrade routine copies value of "Additional
Hardware Version" from existing firmware into offset "0x2023c" in
provided file, _before_ storing it in flash. In case of vendor firmware
upgrade files (which all include U-Boot image and two headers), this
offset points to the matching field in kernel+rootfs firmware part
header. Unfortunately, in case of LEDE factory image file which contains
only one header, it points to the offset "0x2023c" in kernel image. This
leads to a corrupted kernel and ends up with a "soft-bricked" device.
The good news is that U-Boot in these devices contains well known tftp
recovery mode, which can be triggered with "reset" button. What's more,
in comparison to some of older MediaTek based TP-Link devices, this
recovery mode doesn't write whole file at offset "0x0" in flash, without
verifying provided file in advance. In case of recovery mode in these
devices, first "0x20000" bytes are always skipped and "0x7a0000" bytes
from rest of the file are stored in flash at offset "0x20000".
Flash instruction:
Until (if at all) TP-Link fixes described problem, the only way to flash
LEDE image in these devices is to use tftp recovery mode in U-Boot:
1. Configure PC with static IP 192.168.0.66/24 and tftp server.
2. Rename "lede-ramips-mt7628-tl-wr84...-squashfs-tftp-recovery.bin"
to "tp_recovery.bin" and place it in tftp server directory.
3. Connect PC with one of LAN ports, press the reset button, power up
the router and keep button pressed for around 6-7 seconds, until
device starts downloading the file.
4. Router will download file from server, write it to flash and reboot.
To access U-Boot CLI, keep pressed "4" key during boot.
