Writing sector failed
I'm trying to flash a bk7231N smart switch but I have write fails. Changing baud rate only changes the point at which the error occurs, this is the log:

Tried also the change usb port but nothing changed, do you have any idea?
I am getting the exact same issue

Flashing a BK7231N CB3S
Tried multiple programmers and usb ports.
Same with aubess smart swich (2 of them). both itchiptool and openbeken fail to flash. Can't revert to stock for now. EDIT: Revived one by lowering baud, managed to flash obk. WIll try the other one in a second. No luck with the second device. Second day update: revived the second one with a different laptop. Failed at first with baud rate 115200 and 921600 (wich worked on the first aubess on the other computer), finished flashing with baud 1500000. Same cp2102 adapter. Had to resolder one of them to rewrite rf because mac was C8:47:8C:00:00:00 on both.
Same for me, I'm not able to revive my Aubess smart switch beceuse I can't flash the dump.
Failed to write previously flashed tuya smoke detector. Maybe some online dependency is broken?
The same for me wit smart plug Smart Socket Chip BK7231N Firmware: OpenBK7231N_QIO_1.17.614.bin
