"unknow image" for xx20 when pulled from Lenovo website and applaying me_cleaner on it

[tlaurion]

Hello @corna !

I managed to do a PoC to be able to build totally reproducible builds for Heads on xx30 linuxboot/heads#703 and trying to replicate the same process to xx20 without success.

wget  https://download.lenovo.com/ibmdl/pub/pc/pccbbs/mobiles/83rf46ww.exe
innoextract ./83rf46ww.exe
me_cleaner.py -r -t -O me.bin app/ME7_5M_UPD_Production.bin

outputs : Unknown image

Why is that?
