OpenWrt Factory Firmware: Use this file the first time you flash OpenWrt onto the router as it came from the “factory.”
OpenWrt Sysupgrade Firmware: Use this file to upgrade an OpenWrt “system” to a newer OpenWrt version.
OEM Stock Firmware: Use this file to restore the router to the “stock” firmware as it shipped from the manufacturer.

Install OpenWrt

For Archer C7 (confirmed for v1.1, v2, v2.1 and V5 (fw1.0.11) installing OpenWrt is confirmed to work by simply uploading the OpenWrt firmware in the stock OEM's firmware-upgrade page.

Please note however that this page will refuse to install firmware uploaded with a long filename. To bypass this limitation, download the relevant factory-flash BIN-file and then rename the file to firmware.bin before uploading.

For older stock firmware version for the Archer C7 V5, installing OpenWrt is only possible through TFTP server, (V18.06.1 confirmed) Make sure to upgrade the stock firmware first if you want to use the manual firmware upload feature which can be easier than setting up a TFTP server.

It is possible to install OpenWrt over TFTP on this model. The same method also works for restoring back to the stock firmware.

generic.flashing.tftp

Connect one of the LAN ports (might need to be specifically port 1) to a machine running a TFTP-server. Configure the server machine with IP 192.168.0.66/24 [1]. The router will run as a TFTP client at 192.168.0.88.

Obtain a stock firmware or a 'factory' OpenWrt image. Store the firmware on the TFTP server as ArcherC7v2_tp_recovery.bin. Replace the v2 with your hardware version number if you don't have a v2.

To start the TFTP recovery process on the router, press and hold the WPS/Reset Button and then power up the router. Keep the WPS/Reset button pressed until the WPS LED turns on (it's the LED with two arrows pointing in different directions).

Note: For Archer C7 v2, there is a combined WPS/Reset button. For Archer C7 v4 and v5, you must use the dedicated “Reset” button near the power button.

If everything went right, you should see a read request in your TFTP server. The flash operation takes about 3 to 5 minutes.

Archer c7 v5 back to the original software I also had this problem and I can upload any software to C7v5. I just tested today, I know a lot of users have this problem. It has always been tftp over time that it has timed out. It is known that in the network card we set the ip address: 192.168.0.66 mask 255.255.255.0

Now use this tool: tftpd32

Everything is almost set, you just need to unpack the access path (i.e. in tftp you press BROWSE and you choose in the main directory i.e. (tftpd32) is the original C7v5 soft tplink, while in other directories there are softs (ddwrt, gargoyle, openwrt) that with an unoriginal software you can upload a second soft, but using a browser. For example, I uploaded the soft ddwrt from the directory (ddwrt factory) then you need to upload the second from the same directory through the soft browser (tplink_archer-c7-v5). Uploading software: once you have the network card set up. fire up tftpd32 select the soft you want connect the router to your computer using a lan (router turned off from the power button at the back) now turn on the button on the back and simultaneously hold the reset for about 7 seconds. it will start loading soft into the router, wait about 10-15 minutes for the lights to light up.

[1] The TFTP server may need to be at 192.168.1.66 - see https://forum.openwrt.org/t/tp-link-archer-c7-v1-v2-jtag-u-boot-recovery-using-st-link-v2-usb-adapter-clone-known-as-baite/39582/43

Archer C7 v1, v2 and v3 should all be possible to recover from damaged u-boot via JTAG, for v1 JTAG recovery is confirmed.

TP-Link Archer C7 v1/v2 JTAG u-boot recovery using ST-Link v2 USB adapter clone known as Baite

Download Versaloon firmware (md5 ed4f8fee72e27a4297248d572c784583) for the adapter and flash it to the device following this procedure:

Get an USB-UART adapter, in this case CP2102 was used and connect it to Baite as shown in the photo.

UART-Baite Pinout

Plug in the USB-UART adapter to your PC and flash Versaloon firmware by issuing these commands:

Important: Do not plug in Baite adapter to USB port at this point!

stm32flash -k /dev/ttyUSB0
stm32flash -u /dev/ttyUSB0
stm32flash -o /dev/ttyUSB0
stm32flash -w Versaloon-STM32F103C8_Baite.bin -v /dev/ttyUSB0

Note: this was done on ubuntu 16.04.6, other OS may recognize USB-UART different than ttyUSB0, -k and -u parameters disable flash read/write protection, -o erases flash and -w writes firmware to it

Disconnect the USB-UART adapter from Baite and verify that the new firmware is running properly by plugging in Baite to your PC. lsusb should display 0483:a038 STMicroelectronics ID.

Disconnect Baite from PC and proceed with JTAG connection to the router. You need to connect 5 pins to the board: TCK, TMS, TDI, TDO and GND.

Wiring schematics:

Baite-Archer Pinout

Next plug in Baite to your PC, and short CS pin of the SPI flash chip on router to one of the router's GND pins. Power on router and remove the object used to short CS pin after few seconds (when ethernet LEDs go off)

Now run the actual debug program, OpenOCD:

openocd -f interface/vsllink.cfg -f target/ath79.cfg

It should display the following content:

it's because versaloon have some bugs. Simply run again:

openocd -f interface/vsllink.cfg -f target/ath79.cfg

If dumping image exits to prompt

> dump_image boot.bin 0x9f000000 0x20000

it may indicate problems with JTAG wiring (unconfirmed) or bug in openocd (i've compiled master version, you can try older/stable openocd release) First several attempts to read flash this way worked for me, even with adapter khz 150, but later it always failed (no matter if set khz to 1, 10 ,50, 80 or 100), sometimes it managed to read part of flash and then the process was interrupted. Slow flash reading still works, e.g: flash read_bank 0 blk1 0x00010000 0x10000

Note: When u-boot is partially damaged (but still no output on serial console) it is required to pull CS pin of the SPI flash to GND, in order to enter JTAG mode. When u-boot is completely erased, or damaged from the first sector in flash then CS pin remains low on bootstrap (after initial transition from high to low) and it is not required to short GND pin to CS for JTAG to work.

On Archer C7 v1, the Wi-Fi driver (ath10k) causes a boot loop. This 5 GHz Wi-Fi card is unsupported anyway, so the ath10k driver has been removed from release images:

Another solution would be to remove or replace the mini-PCIe card of the 5 GHz Wi-Fi.

See FS#1743 and PR1349 for context and details.

If the image is not downloaded fully, or fails while downloading: Set the anticipation window of your TFTP server to 1024 bytes. This can be done in Tftpd32 by going to Settings > TFTP.

In some cases, TFTP downloads fully, but the image is not flashed on the Archer C7. That is, the leds continue cycling through the same on/off pattern.

If you had a serial connection, you would probably see output like this showing the file was rejected:

Bytes transferred = 16252928 (f80000 hex) original_product_id = ffffffff original_product_ver = ffffffff original_resvered_id = ffffffff original_special_id = ▒▒▒▒▒▒▒▒▒▒▒▒ recovery_product_id = c7000002 recovery_product_ver = 01 recovery_resvered_id = 00 recovery_support_list = compare special,ret:0 auto update firmware: product id verify fail! Autobooting in 1 seconds

The normal thing is to hook up the serial interface and do some extra commands so the file isn't rejected. A simpler thing is to modify the binary you're using, to match the expected id info above. The stored information in NVRAM is corrupted above..it is all F's. Another possible corruption is all 0's. I used a hex editor (like Flexhex in Windows) and modified locations 0x40 thru 0x47, (which had the 0xc7000002, at least for a OpenWrt binary) and also 0x48 thru 0x4f. I modified those locations to also be all F. (total of 16 bytes of F).

I then renamed the binary as described elsewhere, in my case ArcherC7v2_tp_recovery.bin and redid the TFTP process. The TFTP worked, and the file “took”. This was all done without seeing the serial output..just guessing at a typical corruption/mismatch.

The led lights stop flashing if the file is accepted and loaded. That's when you know you've modified the bin with the correct id to match the corrupted values.

I've examined a number of binaries. All seem to have C7000002 00000001 in those 16 bytes. This includes the stock binaries from TP-Link. I think this explains how the TFTP process can accept either stock or OpenWrt bins if there is no NVRAM corruption. It's not some kind of exact version information for the specific binary? Somehow the value being compared gets corrupted though. In my case, all I did was aggressive/unknowing reset. I wonder if the corruption is related to trying a 30/30/30 reset?

More detail: I got back to OpenWrt with the above all F mod to a OpenWrt factory .bin. I wanted to then get back to TP-Link oem and modified (with F's) a (bootloader) stripped .bin, specifically Archer-C7-V2-FW0.0.3-stripped.bin. I loaded that with the OpenWrt webgui.

This got me to oem firmware, but every time I tried to then load more firmware with the TP-Link webgui, it failed complaining about “versions” and failed. This was true whether or not I mod'ed the .bin with F's as above.

I finally was successful loading another TP-Link oem .bin by doing another TFTP reset recovery using an unmodified ArcherC7v2_en_3_14_2_up_boot(150304).bin as the source (renamed to ArcherC7v2_tp_recovery.bin). Remember to wait for the TP-Link firmware to update after the TFTP completes. It takes a couple minutes?.

The unmodified TP-Link oem .bin successfully took, and resulted in this status in the TPLink status web page:

Firmware Version: 3.14.2 Build 150304 Rel.58409n Hardware Version: Archer C7 v2 00000000

It's interesting that the recovery firmware has a 1 in the second group of 8 bytes in the .bin. But that 1 doesn't show up in the status above? it seems like it's the same in all .bins. The “Hardware Version” status reports all 0's after the obvious C7 and 2. I'm not sure the TP-LINK firmware gets that Hardware Version. Especially if it's locked to the hardware, not the firmware?? Or can firmware change it?

I include all this detail, because the path from using modified OpenWrt .bins (with F's) to similarly modified TP-Link oem .bin (stripped) to using unmodified TP-Link oem firmware (not stripped), was more of a hassle than I expected. It's possible the 2nd “.bin with bootloader” from TP-Link overwrote some NVRAM locations that the initial boot-stripped TP-Link .bin didn't, because now I can load a variety of unmodified TP-Link oem .bins from the TP-Link webgui, when I couldn't before.

It was critical that the unmodified second TP-Link .bin was loaded using the TFTP recovery mechanism, not the webgui. The last TP-Link oem I loaded resulted in this version status. I used the oem webgui to load ArcherC7v2_en_us_180114.bin

Firmware Version: 3.15.3 Build 180114 Rel.39265n Hardware Version: Archer C7 v2 00000000

Pro tip: Sometimes you need your computer to have a 192.168.0.x ip address, and sometimes 192.168.1.x. You can speed up the process of setting up the 192.168.0.66 TFTP server, and testing 192.168.0.1 or 192.168.1.1 responses, by having two laptops plugged into the back of the Archer C7. One setup manually for a 192.168.0.x ip, and the other setup for a 192.168.1.x ip.

This way, rather that constantly wrestling with changing your IP address on a single computer, you just use whichever laptop has the right IP address for whatever the recovery step needs. I actually had a Windows computer acting as the TFTP server, and a Linux laptop for the 192.168.1.x work. I also could unplug them and enable their wifi for internet access when necessary for getting binaries or reading.

Also note: the latest firmware from TP-Link may complain about versions when loading alternate firmware or earlier oem versions from its webgui. I found I had to revert to ArcherC7v2_en_3_14_2_up_boot(150304).bin with TFTP recovery in order to experiment with DDWRT after all this. I successfully loaded DDWRT firmware with the TP-Link oem webgui when I used that particular oem version. I forget if I was able to use the webgui on the newest TP-Link firmware to load OpenWrt originally. In any case, the oem version mentioned works for that.
