when flashed this bios laptop stuck on surface logo. I have found the the latest UEFI ROM from microsoft, but it's not the full size of the bios region (Bios Region after opening in FIT tool is 10MB). does someone know how to build it to the bios dump? also attached the ME region came from microsoft. and also the EC rom (which came separated, maybe the EC is programmable? or has additional chip for EC rom?)

All files you get from Microsoft are not BIOS.

Original bios error what ?

original bios error, laptop turn on, but no display. after flashing Surface pro 4 i7 8g x911788-009 W25Q128(8K BIT OTP) BF.BIN ----- show display but stuck on surface logo. of course i cleaned ME region. still stuck on logo, can not boot to usb nothing boots

also tried Surface Pro 4 different bioses from this website, all gave no display (probably same model, but different motherboard)

i think the problem is not only bios. i think there are more eeprom, that need to reprogram. i took this dump from this chip near the EC chip. i think it's the EC rom. can you confirm? do you have a dump?

i think you only care file 16MB

 

[macabi170]

i think you only care file 16MB

but i tried so many bioses, but it just gives me surface Logo. i put windows PE USB drive with LED. and it blinking, which means the surface is working and loading windows, but only shows the logo

Hang logo display ?

 

[ThienBui]

Hang logo display ?

try more BIOS this

 

[macabi170]

try more BIOS this

tried this also, same result. hang at logo. not really hang, because usb with PE windows is blinking which means it works in the background and loads the windows, but doesn't show anything else than logo

 

[macabi170]

i put another Windows PE USB drive, which has windows logon sound. and i hear the logon sound which means, the machine is booting and working in the background. it makes me highly suspect it is the EC rom which is bad too.

do you have the EC dump?

it's a W25D40V chip

i no have, but i sure problem not from it

 

[macabi170]

i no have, but i sure problem not from it

don't be sure.

the problem was after w big windows update, which updated the Bios rom, the EC rom, the Touch rom, the SAM (Surface System Aggregator) rom and the ME region.

all of them got corrupted during the update, i don't know why. maybe micro$oft, tries to kill these surfaces.

i have reflashed the bios with a good bios dump from this forum, and clear ME myself.

now the surface turn on stuck on logo.

but, windows is working in the background, i connected with RDP.

the only FW i can't fix is EC rom and TOUCH rom.

I need a good dump for them.

please help me find a good EC dump, because i have 2 surfaces with the same problem

All the BIOS I have provided above is problematic, depending on which device you need to identify.

my Surface pro 4 motherboard is x911788-009.

i don't think all the bios is problematic. i think the EC rom is bad
