Re: Please help with unlocking BIOS password from bin file Lenovo X380

Hi . Finally I have CH431A.

I have a X380 yoga mainboard (DTZS1 LA-F421P). I don't know if it is password locked. It starts, nothing in display and then it sounds a melody. (According to the Lenovo acoustic identification app, the error is: 0285: TCG-compliant functionality-related error (might be the TPM initialization failure), I have seen it is frequently related to bios upgrade problems
)

I have followed the procedure of patching the bios.

https://www.badcaps.net/forum/showthread.php?t=87588

Surprisingly, mainboard works with patched bios, no melody, lenovo logo appears and I have followed the procedure:
...
STEP 6: Press space bar 2x when asked
STEP 7: Turn off machine
STEP 8: Restore original BIOS

But, after i restored the original bios, again nothing in display and a melody.
What can I do? Is the original bios corrupt? If so, why does the patching work? can I download a standard one, where can I get it? And what about the CRC?

My original bios:

update: I was impatient and I downloaded to mainboard the bios that is in post #35 of this thread

https://www.badcaps.net/forum/showpo...6&postcount=35

It works!!! I have tried Linux and Windows 10 and apparently everything works.

However, something annoying happens. The laptop takes 30 seconds, with a black screen, until it starts to boot and the Lenovo logo appears on screen. It also takes a long time to resume from suspend.

I have checked the model in the BIOS, 20LJ-S34P0Y. The same is on the sticker in laptop cover. So that shouldn't reflect the installed bios.

Have I downloaded maybe a bios from another model? What else could be happening?

update 2:

I have been trying upgrading and downgrading several bios versions through lenovo repository for X380 yoga. I have reset the bios to default, I have tried changing many parameters (quick boot, lan boot,...), but the laptop still takes 30 seconds until the first Lenovo logo appears to access the bios. I have done all the diagnostic tests on the board and it passes fine. Also, when I suspend and resume in Windows or Linux, it takes 15 seconds to wake up.

Any idea what could be the problem?

update 3:

Maybe the problem (Long time to boot until seeing the Lenovo logo) is related this. ME (Intel Management Engine) firmware is missing in the BIOS.

Could this have anything to do with flashing the BIOS?

X380 Yoga Laptop (ThinkPad) - Type 20LJ

A doubt. Is it required to flash it again with CH431A or would there a way to do it via software?

Can you use FPTW64 -greset as I have read in another guide?
