X1 Nano Gen1 Stuck at Self Healing backup progressing 100%

[darthcloud]

I started the BIOS update from KDE Discover Updates so not sure what was my original version.

I recall the BIOS update process at one point did a memory training step IIRC.
After that it got to the "BIOS Self Healing backup progressing" screen.

It got stuck at 100%, I let the laptop run for an hour+ at that screen and it didn't progress futher.
Turning the laptop off & on again resulted in going back to the "BIOS Self Healing backup progressing" screen and getting stuck again at 100% all the time.

I tried the pinhole reset with no success, remove battery didn't help either, also removed the NVMe card didn't help. The laptop was basicly a brick.

In the end I had to desolder the GD25R256D serial flash IC from the motherboard and reflash it with a BIOS image I found online with my minipro programmer.

That did revive the laptop!

Here the logs I got back from fwupdmgr after fixing it:

I made a dump of the BIOS chip in the bad state before rewriting it in case you want to take a look.

Wowsa, well done for managing that. There's not many of us that can do hot-air rework these days :) Could you upload the old image somewhere please (e.g. zip on github) and Mark can ask the ODM to look.

Kudos on recovering the system.
Internal ticket LO-3432 created - I've asked the FW team for input on what caused the problem.

[ChiWei-Chen]

Thanks for reporting this.
The FW team has added a restriction in the metadata to prevent this jump. Also, the latest BIOS 1.64 has been released to the stable channel.

Updated everything from fwupd in the shell this time one by one.

Everything worked fine this time. On BIOS 1.64 now.

Thank you!!

Uploaded all the reports.
