Re: Lenovo ThinkPad T470s BIOS
anyone got a BIOS file I can use for my T470s 20HF-0047GE PC-0L6NAM?
Reason for request. After "normal" BIOS update the laptop did not start anymore. Not even into the BIOS.
I was hoping to get it back working by flashing it via AsProgrammer but need a working bios dump for that.Comment

Re: Lenovo ThinkPad T470s BIOS
Thankts! Worked fine for me although using a clamp.
Seems it was necessary to delete the BIOS first from the chip as otherwise the re-read was consistently (write-read always returned the same files so flashing via the clamp seemed to work) different from the original file.Comment

Re: Lenovo ThinkPad T470s BIOS
Thank you, hoaca388 for this bin file. I used it for flashing my T470s 20HF. This laptop can only boot to see some flashes of the keyboard light after the late BIOS update using Think Vantage from Lenovo. Now I can at least boot into BIOS setup page after flashing this BIOS file with a new bought CH341a programmer. And thanks to @dahnking for the confirmation of working.
However, after some other fixes (patching with BIOS AutoPatcher by @Knucklegrumble ), I finally got into my Windows 10 system. Then, I found that the Fn key not working, but the Esc key worked for the function of Fn key. I think this may be because of the type does not match.
Still, thanks a lot.Comment

I've tried a few programmers with the CH431A Pro, and the only one that could detect the chip was AsProgrammer, but it only seems to support the W25Q128BV and W25Q128FV chips. Any help?
[Edit] I've found this one, and it programmed it properly!Last edited by justShowMeTheDownload; 11-25-2023, 01:14 PM.Comment

Well, the site wouldn't let me attach anything, my account is too new, I guess.
It says, "Upload failed. You are not allowed to upload files with the extension 7z."Last edited by justShowMeTheDownload; 11-27-2023, 01:12 AM.

I still need help with this, restoring the backup of the bios doesn't fix the problem, I cannot upload it here, nor post a link to it. I feel cornered, I really need this machine to work.
Also, if I do not enter bios, I get two errors:
0271: Check Date and Time settings.
0183: Bad CRC of Security Settings in EFI variable.Last edited by justShowMeTheDownload; 11-27-2023, 01:53 PM.Comment

Okay, I've tried it again today with a different programmer, and it works! And the password is down too!!!
For future users that might struggle with this too, I've used NeoProgrammer, downloaded from here.Comment

Need Clean BIOS/EC Bin File for Lenovo ThinkPad Yoga 11e - Stuck with 0275 Error CMS
Hello everyone,
I am attempting a repair on a Lenovo ThinkPad Yoga 11e that is currently stuck at boot with the error: "0275 error CMS" even after setup new bios battery and will not allow me to enter the BIOS/Setup.
This is a critical issue that I believe requires flashing the BIOS chip directly using a programmer (e.g., CH341A/RT809H), as standard software updates or resets are not possible.
I have opened the laptop and identified the main BIOS chip... -
