Hi
Coming from this thread: Lenovo M900 Tiny Bricked - #72 by MeatWar I decided it’s maybe better to make my own, to not hijack such an old thread.
I have a similar Problem:
After doing a BIOS Update, during flashing, it got stuck and froze, update was via Lenovo Vantage. after multiple hours I powered the system off, which is now in a state of immediate power-on, but no display/beeping at all.
BIOS Recovery procedures did not work like described here: English Community-Lenovo Community
and my own one here:
After my Ch341a programmer finally arrived, I backe dup the existing broken firware multiple times, and pulled a working bios from another same device I had lying around.
Broken model Info:
Thinkcentre M900 Tiny 000GMZ
Machine Type 10FM
Serial Number S4T54658
ProductID: 10FM000GMZ
I attatched my full dumps in the zip.
Sadly when just programming the working_1.bin to the broken unit, it does still not POST. After that I noticed, that after programming then veryfing or reading then comparison I get errors/another hash.
So I tried unprocted → erase → program → verify, but it still didn’t POST.
Any ideas what parts I’m missing/doing wrong?
I’d really need that computer fixed.
Thankful for any tips/advice!
