Re: T470 bios needed
I'm not sure my solder skills are up to it.
isn't the fact it starts reading a sign the spi communication is ok?
Can the reason be it hangs, it is corrupt?Comment

Re: T470 bios needed
No, if it was "corrupt", the laptop wouldn't turn on.
It's just the crappy chinese clip doesn't make a good contact at some of the chip legs, or/and the cable has become unsoldered on one of the pins (the cable is also thin and crappy), that's why.
Edit; You have to read the chip, then erase it, then program it with the patched dump, then erase it again and program it again with the original dump. I just don't see how it's going to happen with that crappy clip...

Re: T470 bios needed
Yeah, i get mixed reactions from different usb ports. Maybe the chip is drawing to much power. got a 90% read one time.
The laptop doesn't realy turn on.
The keyboard illumination and power button briefly turn on, then everything shuts down.
I'll try to desolder it tomorrow.
If i get succesfull reads, schould i flash the bios posted in the beginning of this thread?
Thx for the advice so far

Re: T470 bios needed
Oops my mistake - I did not read the whole your first post because of the obviously smaller archive, thought the goal was unlocking but that doesn't change the meaning of what I said, the chip very rarely happens to defect, the much more likely cause of your problems is what I already told you.Yeah, i get mixed reactions from different usb ports. Maybe the chip is drawing to much power. got a 90% read one time.

BTW what do you mean by "corrupted in a bad flash" - during the Windows update, or something else?

Re: T470 bios needed
yes, during a windows 'system' update.
when i saw it reboot into a flash, i scrambled for my charger, because i didn't want the battery to die, but i must have bumped it or so.
It's my old work laptop, but the password was already removed. was running perfectly until the windows update went wrong.Comment

Hi, I have an MSI PRO B660M-G DDR4 board with damaged BIOS and i need a bios dump from a real board, along with MAC, UUID and Serial Number info (eg. a BIOS screenshot and pictures from the board stickers).
I need to reconstruct the bios on my board, based on another bios image form a real board - meaning a bios image containing MAC address, UUID and Serial number. A stock BIOS is not suffiecient, as it is impossible to discover where the MAC, UUID and SerialNumber are stored. Tried with a similar board, but there are too much differences, and the stock BIOS is missing a lot of...11-17-2023, 10:56 AM -

Hi everyone,
I'm trying to recover a Fujitsu Lifebook E5513 (most likely 2023 model) that was bricked during a BIOS update. The update was interrupted (probably due to power loss), and now the laptop is stuck in a boot loop showing "PBB rollback" / "SBB rollback" messages.
BIOS access (F2) and Boot Menu (F12) are no longer possible – the system instantly reboots after the rollback messages.
I extracted the official BIOS update package from Fujitsu (contains FJNB2FD.CAP, ~18.7 MB) and tried tools like UEFIExtract, but it seems to only contain...
