HP Pro x360 Fortis 11 inch G9 Doesnt boot after flashing bios

[kenkaniff]

Product Name: HP Pro x360 Fortis 11-inch G9
System BIOS: U94 Ver.01.08.00 10/06/2023
Serial Number: 5CG31946F5
SKU Number: 85W05EC#AK8
Motherboard: ANOLE10-MV-TRIPOD / 6050A3332901-MB-A01 / 2021-11-09

This motherboard has 2 similar chips. One is on the front marked with BIOS SKT "Winbond 25Q256JVEN" and one on the back marked with U351 "Gigadevice 25B256EYIG". I ignored the one on the back and only desoldered front chip. Made a backup, made sure the reading was the same with another 3 backups.

I needed to remove bios password so i followed this guide https://www.badcaps.net/forum/troubl...y-bios-patcher

Script run succesfully so i flashed the bios with modified bios file and at the end verified the flash is good.

After soldering back the chip, computer went into a bootloop(always blackscreen tho), power led flashed blue and white each 2 times and then power button led lit up as it was trying to boot, cpu was also getting hot which means it at least communicated. But after that nothing, just bootlooping till it turned off. And i probably did something i shouldnt have(held win key+b) and it did booted a bit differently and after that when i desoldered bios chip and tried to verify the chip content was changed.

So now i tried to write original locked bios and and verified a good write before soldering. But now when i try to boot even with original bios the power led(next to power jack) flashes 1 blue 1 white 1 blue 1 white then turns off, then flashed 1 blue 1 white 1 blue 1 white and turns off the computer completely. Cant even turn it on anymore. Also the cpu doesnt get hot/warm anymore, so probably not even communicating anymore.

Could you please help me fix this issue? Added original locked bios in attachments

if it doesn't work with your original bios perhaps you read your bios chipset with errors, that's why is recommended to read bios chipset 3-4 times and compare results, when you have 2 identical it means you have a good backup.
I found errors in ME_Region, I cleaned it and put it in mpm. Try it.

Worked perfectly, thank you

I think i somehow corrupted bios content before making the backups, because that is exactly what i did and do everytime - i make like 4/5 backups and compare them with hxd. In my case they all came back identical.

you are welcome. Maybe didn't work because of ME_Region being faulty.
