X1 Yoga 3rd (20LE)

[drjlt]

Hello,

Anyone has a clean BIOS for X1 Yoga 3rd, type 20LE (seems not to matter)?

I have a bricked laptop after flashing with the CH341a in Windows. Now I try to flash with Ubuntu using flashrom, which seems to be more stable and easier to use.

I'm not sure that my original dumps were correct.

Either that, or the machine has other electrical problems?

Thanks in advance.

Hi, this is one of the initial reads.

Re: X1 Yoga 3rd (20LE)

btw, now the power button lights up for a second before everything is turned off. The power button becomes unresponsive until the reset button is pressed (or battery disconnected).

I hope to find a good copy of the BIOS to try and rule out other electrical problems.

I flashed the .bin extracted from Lenovo's official BIOS (linux version) in Windows using NeoProgrammer, although that file is 9MB and flashrom refuses to flash it to the chip.

Correction:
I just realized that the 9MB bin from Lenovo is only half of the BIOS called "System Firmware N25ET60W"; there's also an "Embedded Controller Firmware N25HT33W". Should I combine them?

X1 Yoga 3rd Gen (Type 20LE)

Thank you very much for the BIOS file.

Unfortunately, even after flashing and verified with flashrom, the same symptom remains for this machine:

Press power button, it lights up half a second and becomes unresponsive.

Must have other issues on the board. As I see the board has been repaired or replaced before (some screws half stripped and antenna cables not fixed properly), it could be electrical.

Anyway, thanks again for the file. Someone else may also find it useful!
