Lenovo T470s Bios

Hi, I'm trying to update my laptop bios with a password and I don't care about data on disk.

Laptop: Lenovo T470s
Type 20JT-S0VY00
Bios: 25Q128JVSQ
Programmer: CH341APro
Software: NeoProgrammer and AsProgrammer

1. I read twice with incorrect chip configuration the Bios
2. I compared them and were equals
3. I patched with lenovo_autopatcher
4. Write patched bios
but I suppose that as I readed wrong on step 1, it will not work anymore.

After that, I look on internet for a lot of different bios versions and write them without luck.

What I'm doing wrong?
How could I recover this laptop?

Thanks in advance

Re: Lenovo T470s Bios

I don't think you misread the bios file, maybe writing the bios file to the chip is faulty if you use the CH341A with a clamp. Or you can try cleaning the ME area of the original file.

Try this 16mb file. there is nothing to do with your 1mb EC.

Hi Thx a lot, but it is not working ... I flash the bios, but when I plug the PSU, the power button light up for a moment and stays dead ... not possible to power up. From time to time the cooling fan turns on for a moment and then turns off. All BIOS files do the same behavior. I have used the NeoProgrammer with Ch341a and XGecu TL866II plus ... same result. Am I doing something wrong? Hopefully, I haven't destroyed the motherboard
Or should I desolder the bios chip for programming?

Re: Lenovo ThinkPad T470s BIOS

Try anyone of the zip attachments, all should work as they are in original form & only asked for P/W removal or not booting up fast... One Should work.

I used a patched one and it displayed hardware id and I pressed enter and space bar a couple times and shut it off.

Can i flash it with any non patched bios now and it should work?
