Which chip(s) did you dump?
And which chip(s) did you flash with which file(s)?
I attempted a straight OEM 2022 BIOS update. But I clicked the EC update (unbeknownst to me the Tower motherboard has had no EC update since launch, so I was flashing the Thinkcentre Tiny EC). It hung and has not posted since. No beeps, nothing. The EC chip is 1MB, while most dumps I can find are 128KB. Iāve tried various 4mb+8mb āME cleanedā images. Black screen, no beeps. The last one had all 3 images (Badcaps .net), and it tries a reboot as though it was resetting the ME or training the RAM, but still no POST. I have to believe the checksums arenāt lining up and the ME isnāt happy.
Just a warning not to skip dumping all 3 chips before attempting anything. Even a Lenovo BIOS update.
Well, Iās still taken a dump after the brick. But if several images are already triedā¦
Thereās a reference tp EC firmware for tiny versus other formats here:
