TP-Link WA850RE v2.0 Bricked

Note that excessive heat form soldering could damage some components if you are not careful. don't keep soldering and re-soldering (I see indent marks on the board from the solderer, so be careful, never let the solderer touch the board, certainly anywhere other than the soldering points, and also not for longer than necessary.

Baud rate seems to be the usual, though I'm not sure if it's also that for this particular device. It wouldn't harm to try other baud rates.

I don't know if you have to to bridge points, but I wouldn't try anything like that until I'm 100% sure.

Check with the guys in this topic Bricked TL-WA850RE v2 to see if any of them faced a similar problem if they go t to that point.
