Re: T470 bios needed
They probably assume it will be 8MB. Also sometimes it has the same package as the BIOS chip (SOP8/SOIC8).

Re: T470 bios needed
25Q80JV is the most famous spi chip around here.
I don't understand why rookies likes him the most, probably because of the number 80 on the marking.
Edit:
Yes it is, that's the right one. Are you using a clip to read the chip?

seems to be the right size, but the read freezes (neo 2.2.0.10)
Current programmer: CH341 Black
SPI ID: EF4018

Currently selected: W25Q128FV [3.3V] 128 Mbits, 16 Mbytes

Re: T470 bios needed
101.4 KB is far away from a good read. Try again be more careful.
Use NeoProgrammer V2.2.0.10

Re: T470 bios needed
I got my t470 20HE corrupted in a bad flash (no boot).
The winbond is a 25Q80JV 8Mb chip, but all I see here is 16Mb files for this bios.
I used Neo programmer and a ch341 to read the bios.
Am i missing something?
is there a way to extract a bin file from a bios update?Leave a 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...
