Topic: Bricked e4200 v1 SPI programmer recovery ?
hi folks.i have a bricked e4200.i tried serial but i cant interrupt the cfe so if i get it right i have to erase somehow the nvram to recover it.jtag could be an option but i dont have jtag adapter / parallel port but i do have a ch341 spi programmer and spare winbond flash chips too
can you help me how to apporach it?
firstly do i have to desolder the flash chip to write it?
does it enough to clear the chip and write just the cfe on it than continue in serial?
or may i need a full flash dump?
