Hello, I'm having trouble booting my T480s after a BIOS flash. I'm using a Pi Pico 2040 (serprog) with flashprog.
I dumped the stock BIOS three times, the checksum was the same. I added the usual patches, and how the laptop won't turn on: attempting to power on for a second (display powers up, keyboard lights up), power LED blinking three times, fan spins every few seconds.
Reflashing the stock firmware didn't help. I tried reflashing after using me_cleaner on the stock image, still nothing. Tried some BIOS images from around this forum, nothing. I even tried Coreboot, nothing.
The diodes and SMD components close to the BIOS chip seem to be okay, I checked with a multimeter.
The model code is S0L8-S6RF00, serial number PC-12ZR7C, i5-8350U
I'm attaching the stock BIOS and the modded one, thank you.Last edited by xugopef@mailapps.online; 10-09-2025, 05:44 PM.Comment

Update: it's indeed a hardware issue, the clip knocked off the two 33 ohm resistors on the bottom!
I got it to boot with some bodge wires, not ideal but better than dead. I might get a new motherboard later since I ripped some pads and I don't trust the wire, and recycle this one as a server (I wanted one for Home Assistant Voice anyway).
Thanks a lot for all the help!Comment

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.
I have successfully used a CH341A programmer and can read/write/verify both flash chips, but using my backups/extractions has failed to restore power. The root cause is likely a corrupted Intel Management Engine (ME) region or an incompatible EC/BIOS pairing. System & Hardware Details- Barebone / Chassis: TongFang GK7MRFR

Hello. I am asking you for a hint on how to solve the problem with my touchbook Panasonic CF53-2 standart model. After setting up the BIOS, the laptop displays the wrong image until Windows loads. (More precisely, it displays, but distorted, instead of the Panasonic image immediately after turning it on, it displays what is in photo #1 in the attached file) Then the image appears when Windows starts loading and then there are no problems with the screen until the reboot. If you enter the BIOS, just a black screen. If you connect an external screen, the image on it is the same as on the built-in... -
