Default Re: I need bios dump for Microsoft Surface 4

Anything that is able to read bios. I am using fptw. But it cant be used to read whole bios. I use it to read bios region only but that is where the password is. And it cant be used to write bios (otherwise unlocking 4 would be very easy aswell) because there is write protect.

The surface does not turn on.
Nor with an original dump, though, the reading doesn't seem to be flawed.
Do you have an idea?

Unfortunately not good, the original dump doesn't turn on either.
"Copia_ClearPWD" downloaded at second post
turns on but does not recognize the windows update, nothing works.
I'm clueless.

remove the bios chip from the system board before writing or reading.

Yes I made a mistake, I didn't remove it from the motherboard, unfortunately the dump became faulty.
I found another biost for everything that works except Me and Touch.
Some solution would be good for a touch controller.

Can't use anything from the faulty backup that can help?

Thanks.
Power-up time has been accelerated, something has been installed and updated.
I deleted the "internal driver" Me and Touch driver from the control panel, no longer trying to install unsuccessfully at startup.

Bios touch controller firmware : 0.0.0.0
Bios model name: Oem product (so you can find the necessary drivers for the next installation?)

I think the wrong program (ch341 1.34) caused the faulty backup, only v1.18 can read properly write to W25Q128FV.
With 1.18, writing is also successful.
