iphone 4 baseband downgrade - GSM-Forum

dado89 · 02-06-2012, 13:33

i got a new iphone 4 in the shop from usa. i need to unlock it to serbian operators

it has the basbeband 4.11.08

i got the gevey ultra+ card but it unlocks just to 4.10. basebands.

i tried downgrading it in a lot of ways but always get errors in the itunes with or without the tinyumbrella.

any help would be nice.
tnx in advice.

there is no way to downgrade your baseband don't waste time on it wait for the new gevey sim if it comes in future.

u cant downgrad it and u cant use gevey sim
just factory unlock

try to find out what operator phone is locked on, then search IMEI & Factory codes service, you might get lucky, NO way to unlock 4.11.08 by any other way at the moment
