Good day.
I'm seeking information, advice, or fix for a BIOS upgrade that is always failing on a Thinkpad X12 Detachable Gen 1 (Wistron 19835-1). The failure is indicated as "An unexpected error has occurred, and the process did not complete." as shown in (1) whenever I try upgrading the BIOS via the provided official BIOS bootable CD or BIOS Utility (Windows) update releases, practically EVERY version released for this unit as can be downloaded in (2).

Hello everyone,
I am requesting urgent assistance to unbrick my laptop, a rebranded TongFang GK7MRFR chassis. The laptop is completely dead following a faulty in-OS EC flash attempt.

Motherboard: CH580

I can view and edit the content of the BIOS .bin file with AMIBCP BIOS editor.
The BIOS files I'm working with are from badcaps.net and those are CLEAN BIOS files (anyone can find it with the search string: RZ09-0421).

Hello everyone,
I need a BIOS for the Thinkpad L13 Yoga Gen 4.
S/N: PW05KQH7
Type Number: 21FR-0005GE
A recent BIOS update from Lenovo has bricked the laptop.
Currently there is no charging light.
According to Lenovo's website, the BIOS version R26ET41W/EC R26HT28W (r26uj08w) has been withdrawn due to issues with the system failing to power on after the BIOS/EC update.
