[patch snipped] No issues here, and it does seem to have fixed the RAM size detection on my Redmi AC2100. It's always been a very sporadic failure here, so I'll be keeping an eye on it to see if there are any further misdetections. :) In any case, feel free to add my Tested-by: Rui Salvaterra <rsalvaterra@xxxxxxxxx> Thanks, Rui
