Surface Pro 6 - Physically Broken Bios Chip

[Evostar]

Hi Everyone and thank you for having me!

I recently own a 2nd hand i5/8GB/256GB Black Edition Surface Pro 6, which was an upgrade from my Pro 4 which had display issues.

Issues arose with the Surface 6 when I got home and went to do my usual clean and custom Wim image of W11Home I debloated.

fire up the recovery usb > cmd > diskpart > see disk 0 > clean..... (worst mistake this time around)

Well little did I know I can't actually write to the efi partition anymore due to a setting in the uefi. no worries ill disable it! So I restart enter the uefi procedure and I'm in!!!,,,.... wait! what!!! password?!... (I hadn't seen the before due to my Surface 4 not having one..)

Any way I found a way to bypass the efi by using a FFU DISM backup of a fresh install on my Surface 4 and then Applying it to my Surface 6 from the USB recovery, all goes well and I go on my way happy for a few days...

To be honest though, that password is just bugging me... I just want it gone, is I go down the rabbit hole of looking into flashing the bios to remove the password lockout.

So I heat her up take her off the board, and pull out my cheapo Chinese black 341a I had from a long while back.

what could go wrong at this point?

I'll tell you... I drop the programmer with my chip installed to floor by accident whilst moving across the room. and well lets just say I am so angry at myself. so close to having a backup but then breaking the thing just before.

So my question is...

How Can I salvage this chip to get a dump of my bios?

here is the pic of the disaster board....



thanks for listening.

Hi!, and thank you! (first 6 bios I could find) but surely it can't be that easy using a random bios file?

I need to try dump my broken chip for the serial etc data?

which pins on the bios chip are used for programming. (with y luck its both those that are broken....)

All 8 pins, but the chip broke, that's impossible.

Re: Surface Pro 6 - Physically Broken Bios Chip

yikes... ok I will stop chasing that route.

I write down my windows key and took photos of my system about screen. assuming I could as best try transfer manually as much detail as possible to new chip by editing..

I will keep reading and broken my knowledge. before I attempt

thanks for your quick reply mate

appreciated.
