I managed to brick my TP-Link Archer C7 v2 (EU version) (when reverting to stock from openwrt and clicked upload without unzipping the file first) and now all lights illuminate, flash, repeat.
I've tried multiple times to use the TFTP (setup at tftp server on my machine with IP address of 192.168.0.66) to flash a valid image to it (tried both OpenWRT and stock).
I followed the below instruction
Set static IP of 192.168.0.66/24
Run TFTPD32 server with proper directory/image (renamed to ArcherC7v2_tp_recovery.bin) and network interface selected
Hold WPS button while powering on. It does the expected thing and illuminates WPS light/etc.
The TFTPD progress bar indicating the transfer moves to 100% (far too quickly—within 5 seconds), then the router immediately reboots and starts brick-dance-bootlooping again. Furthermore, the log does not show the extended communication that I typically see when flashing devices with TFTP.
I'm confident I'm using the correct images of stock firmware (the same images I've successfully flashed multiple times before.) From what I understand, if the router can enter the "WPS light illuminated" mode, it should be recoverable via this process. It seems unlikely I've caused irreparable damage.
I saw some posts that I require to hex edit (using a hex editor) the stock firmware (containing the word boot) header and cut out the boot.
I opened a the latest stock firmware with a hexeditor, but I honestly do not have any idea where to find the HWID and edit it this is all new to me, is there a thread which could help me with the hex editor?
