T470 bios needed

[Andreasbest]

Unpatched bios, updated to 1.79 + clean Corp LP C 11.8.94.4494 ME firmware

At first it didn't work either BUT i was very curious and i decide to remove everything from the board, first i removed both RAM sticks, laptop powered on with beeping, then i insterted again the RAM and everything worked

Thank you SMDFlea for once again!

Hello.
I came to a very weird situation with a T470.
Laptop worked great but locked, backed up the BIOS, successfully verified it, patched it with Autopatcher, boot successfully and completed the DXE procedure, flashed back the old unpatched bios and now only the green led of power button turns on and nothing else.
Tried CMOS reset but no luck. No physical damage around BIOS chip, i was very careful and checked MB on microscope.
Any ideas?

Both bios attached
S/N: PF-10A0VQ

Thank you in advance!

Dear hoaca388 you are always on the mark. Thank you brother, all worked fine. Even Markus1741 thanks for your bin file, I did not try it but surely yours too might work well. Thanks for all the help.

Dear Friends., working on a Lenovo T470. All required voltages are present & the require Amps (.95mili amps), Also goes through the start process, turns off & then turns on but no display or any beeps. I think the BIOS Bin files are corrupted & has to be re-build. Can some pls. re-build the Bin File, Original Bin uploaded. Thanks in advance.

Hello.
This laptop starts normally, the power button lights green, and the fan turns on. A few seconds later the power button light goes out and the fan stops spinning, the laptop never boots and the screen stays black. The laptop was working untill a windows BIOS update failed, I'm looking for a clean BIOS bin file or a clean up of the corrupted BIOS dump. Any help would be greatly appreciated Thank You.

I'm new to flashing anything for Lenovo. What do you mean when you clean/clear the ME? How is that process done?

search here on the website, you'll surely find it, if you're still looking, read the rules...

After a few hours of work and attempts, I succeeded to bring the laptop back to life, with the original bios fixed.
I read the dump after starting the laptop, to backup it this new generated and repaired file, and for to be able to post it here for other users, too.

Hello! hoaca388 when I want to load the file in XGecuPro, it gives me an error that the file is not good or missing.

[bogdandan77]

Thank you very much, hoaca388, for the answer and support!
I don't know if your 20JV model is compatible with 20HE. I compared the two files a little bit and they have a lot of differences in the lines of code. But I will still try your file in the next few days and I will come back with an feedback.
