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.

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
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?...Leave a comment:

Yep, the full aliexpress package.

Re: T470 bios needed
I found an other one ; 25Q128FVSQ
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
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:
