Hi,
I need your help because I tried to unbrick my wireless router TP-Link WR940N V4 but something went wrong and now it restarts all time. The only way is to connect to the board serial port !!

Then,I have connected my TTL adaptor to the 3 pinholes installed on the board for Serial connection and made solder a couple of wire. Unfortunately my welds are badly made and I don’t have messages or texts displayed on my serial monitor (Putty).

As it is no more possible to make new solder (no more contact) , do you know if it is possible to find / connect Rx and Tx somewhere else that on “serial” pinholes ?
Perhaps it is possible to connect directly to serial Flash memory (25G32) or somewhere else ?

Thanks in advance for your help.
