Bios Mods -The Best BIOS Update and Modification Source

I crashed my EFI Bios of my B113 (Motherboard, Q1VCZ-LA 8941P, HM77, i3-2377M, without Windows)

Long story, I was only able to update until 1.09, I tried to get 2.22 working somehow. (for UEFI Boot, win10)

I found a file from another user and sucessfully flashed it but it had a bios password lock. (stupid idea just to use this file...)

Ok, tried to update same official version, 2.22 with Acer/InsydeFlash tool in Windows. This crashed at 48%, Display went corrupted and finally off. After 15 minutes I rebooted, no boot, Power LED is on, Fan starts, and after a while it starts again.

Normal recovery procedere (Fn+ESC, bios.fd) doesn't work anymore, 1.09, 2.21, 2.22.

So, any ideas? I just soldered 8 wires to the U17 winbond w25Q32BVSIGg chip and tried some hotflashing with an Asrock H77m-itx and the file above. Not really successfull. still no boot.
My next idea is ordering a flashed bios chip or buy a Bios programmer and try...
Next to U17 is U18 located: winbond 25Q80BVSIG, what is this about?

Does someone has a full Bios file and some Dos flasher? (Flash-it?!?)

original bios file:
1.09

2.22

I think LAN MAC address is already gone, may I can write a different address from an old LAN adapter card.

I hope I can get it somehow back to life. Btw: I'm working in IS, and first time I forgot to make a backup... I know, shi* happens...

EDIT:
found "flashrom" tool, my "Hotflash" H77 Board is not supported, ME is locked.
Now installed a Raspberry PI2 and now playing around with SPI programming. I guess this can be cheaper than buying a dedicated programmer.
Now I need a full Bios dump. Or any other ideas?

Please read your Eeprom Chips (Both 32 and 80) Full Dump Firmware then upload
them here and I will rebuild It for You !
I will reupload Patched It and You write back to Eeprom Chip !
Let me know
Regards

Please make a Tutorial using the Raspberry PI2 and I will stick here like this one

It seems that BusPirate and RaspBerry PI are the best Programmer actually !

Are You sure your Chipset is HM77 and not NM70 as there are two Firmware for two
Chipset !
Let me know
Regards

Thank you very much! I will try to get the pi working tomorrow.
Should be HM77 south bridge. Cpu-z told it once it was still alive and it has SLJ8C on the die.

Ok I will wait your news !
Regards

Good afternoon, Pi and flashrom did it
I will gather all information into one step by step guide.

bios.rom (4MB)
Datei von filehorst.de laden

ec.rom (1MB)
Datei von filehorst.de laden



Regards!

Hi mate, does the download work for you? Would be great if you could bring back life.

You're right mate !
But You wrote EC.rom and It's wrong so I had to check all Firmware Original . . .

1. Extract It
2. Extract Regions
3. Compare with yours files
4. Look for Eeprom Chips size involved (thanks You sticked photos)
5. Rebuild all

Here You go :

P.S. We have to replace your DMI Data !

About regions, what to compare with which tool?
Thanks a lot!

Hi mate,
let me know before if It worked !
Regards
