Hi BDMaster, Hi everybody,
I tried to mod my yoga 2 11" bios 92CN35WW by myself with no success for now...
I have a CH341A SPI programmer and read eeprom chip.
Opened the file with Andy's tool 2.59, allowing user mod in advanced options (4 changes only) :
Modified bios lock module 11D378C2-B472-412F-AD87-1BE4CD8B33A6_744.ROM (21 kB)
offset 1AA0 replaces 74 09 with 74 00
offset 1AA9 replaced 75 31 with EB 31
I then flashed the patched bios to Eeprom but it bricked my laptop.
Flashing backup bios file unbricked it fortunately.
I also tried to only modify the wlan pid (same module offset 128A) with the same result : bricked laptop.
So, is there something I'm missing here, like bad tools, bad method or something ?
Any help would be appreciated, please, I'm stuck !
If you need the bios file let me know...
Thanks for reading
