nice nice any other programs or ways to flash this chip or just impossible

From older to new threads on the subject… take some readings, its general guidance, some ICs are hard to deal with, due to motherboard circuit design to the SPi

etc…

EDIT: Even if the whole flash operation is successful, make a new dump/reading again and HEX compare it to the source.

i got verification errors on all of them except the last so far gonna try that now thanks for the help btw

you might also ensure your clip is seated correctly and also consider using a continuity checker or check the resistance on the wires

I’ve had the wires partially break close to the clip side/near the shrink wrap and cause signal issues

also if you have a black ch341a those output too much voltage, you need an adapter or to use a green one

I believe the user knows the IC specs…anyway its an 1.8v IC
(1.65 to 2.0 volt for read, erase, and program operations)
