So, i kinda spend significant ammount of the last couple of days trying to flash a new bios, and or unlocking the current bios password with little to no results.
The whole thing started with it being the 8fc8 bios, i found the tools to unlock that but i needed a bios dump. So i pursued that, im at a point where i dessoudered the chip, and succesfully soudered it to the ch341, dumped whatever was on it.
However, the tools supposed to unlock the 8fc8 say that there is no 8fc8 hex inside. And when i followed diffrent tutorials to just flash a new bios onto the chip i got stuck on the step when you need to find the exact line on the new bios that your old bios starts with.
That prompted me to go down google/forums rabbit hole of searching and trying diffrent things, UEFItool says that this bin may be corrupted, i got lost in tabs i opened in the browser and i relised that in fact i was out of my depth like couple of hours ago.
it all kind led me to belive that the bios dump that i have is either corupted, im not reading it correctly, both, or neither and i in fact have no idea what im talking about.
It would be ideal if i could have the opportunity to actually understand the proccess and what and where i did wrong.
Does anyone have any idea if that dump is in fact correct and intact or am i missing something obvious.
Laptop Dell Latitude 5431
service tag DK55WV3
Laptop was booting before dissasembly with no obvious flaws, other then being blocked by that password.
Chip is i belive winbond 25r128jvsn
I was using NEOProgrammer to read the IC, bin in the attachment.
Clues and help would be appriciated,
