X220T was flashed with non tablet bios

#1 Post by derick » Mon Dec 25, 2017 5:22 pm

Hello, after mistake, I flash non tablet bios 1.43 into X220T and my tablet is not working as tablet anymore. (Work as x220 laptop only). I think, EC controller was flashed with wrong non tablet FW. How I can reflash it back, to tablet version? Thanks for answers.

The way you went one way should work the other way, I would think.

If the Lenovo flasher won't do it, try Winphlash. Sometimes it is bundled together with the Lenovo files.

I tried it. I reflash Bios back to 1.37 version, but controller was not changed. Also FL2 file only was flashed, but no success.

If it lets you, flash to an older version BIOS with different EC.
Then reflash with the proper 'new' BIOS/EC.

This version 1.37 has older EC FW (1.23). I look to bios file and Lenovo says (in readme), that Bios for x220 and X220T is the same.
