Hello @StupidMe,
Despite your chosen name, you're not that stupid in fact. The situation you are into is the one that I feared for myself one day, if I wanted to reinstall the original TP-Link. That's why I ordered a serial cable for recovery just in case...
First thing first: Have you seen this video on Youtube: https://youtu.be/Fi0pC_ON5Vo ? This is a step-by-step to recover your Archer. For the firmware, try the one from FriedZombie, because apparently you must use a stripped firmware when going back to stock TP-Link, unlike the one used in the video which is an unstripped one. The rest of the procedure in the video is fine.
So setup your TFtpd, use FriedZombie's firmware, and please report back so we know that your problem is fixed. Be sure to view the video completely to understand what you have to do. Your report will be important because you'll be another documented proof that we need to use a stripped firmware.
EDIT: @Hophead confirmed that using stripped firmware worked for him - See further in this thread.
Regards
