Question: Actually i'm on ARHD 6.2.1 ICS ROM from xda Member mike. Later i want to try ICS MIUI ROM :-) My Question is, if i want to downgrade to this ROM after all, do i need to chage firmware again? At the moment i'm on 11.68.3504.00U_11.21.3504.13_2 (needed for ICS)
All you need to do is flash let's say eng hboot 1.17 for it to bootup without looping. Or anything below 1.23.
