Lenovo M900 Tiny Bricked

Read the posts on this thread and next time provide machine info as the linked forum also requests it.

Win key is @ 0xfb1200

EDIT: Then rebuild from Lenovo update image, procedures in upper post by lbf6.
What’s strange is not booting with the working_1.bin, as this image seems ok… , (your dump is indeed corrupted), so we wonder if there’s another issue
