Full Flash Dump .bin for Archer C20 V5 / V4 or C50 to Debrick

Olá Pessoal,
Estou precisando de um backup da flash Winbond 25064fvsig de um TP-Link Archer C20 v5, pois ao tentar subir o firmware da OpenWrt, acabei matando o roteador de forma que não é possível consertar via TFTP nem via Serial rx tx, aparentemente o bootloader foi corrompido. As versões dumpeadas V4 do C20 ou C50 também são bem vindas caso alguém tenha. Obrigado!

Hi Folks,
I'm looking for a backup of the Winbond 25064fvsig flash from a TP-Link Archer C20 v5, because when trying to upload the OpenWrt firmware, I bricked the router in a way that, it is not possible bring to life it by TFTP or Serial rx tx, the bootloader has apparently corrupted. The dump from V4 versions of the C20 or C50 are also welcome if anyone has one. Thank you!
