Thanx for the helpful answer.
Am not totaly noob, but i asked this because there is no clear thread explaining that downgrading from stock 4.5.141 to any older versions will cause to brick your phone.
Many are saying that using the pudding will help. also other threads are saying downgrading from 2.3.4 with an unlocked bootloader will cause a brick.
Now am confused.
I just want to downgrade from a stock to a stock Rom, without unlock BL & without Custom ROMs.
If you have an idea, if downgrading from ATT 4.5.141 to an older SBF (ex. 4.5.91) Using RSD is possible without brick, please help.
Or any one can help?
Thanx.
