iphone 3gs restored with custum frm using windows, help needed
my iphone 3gs 3.1.2 old boot room was stuck on recovery mode after installing some files from cydia. i tried blackra, irecovery and redsnow 9.2 to boot it but i wasn't lucky. i decided to restore it to 3.1.2, unfortunately i didn't get the 3.1.2 ECID from cydia. i don't have a mac neither.
i googled for iPhone2,1_3.1.3_7E18_Custom, got it & restored the unit; the restore process completed successfully. now, im sure that the modem version is still on 05.11.07 but the iphone is not activated yet.
now i need your help to downgrade it to 3.1.2 plz.
is it possible?
