modem fm: 4.10.01
sun cellular on gevey sim
sir viardomi earlier tinanong ko kung pwede ko gawin ios 5 ang ip4 ko na naka gevey sim and you said i should use the "custom ipsw" and preserve the baseband,
so far di ko pa nagagawa busy kasi sa work. unang tanong ko po ay pwede ba na straight to ios 5.1.1 build 9B208 for ip4 gsm or dapat up one level from my current version until i reach 5.1.1?
2nd question po, pwede ko ba gamitin ang SAM to unlock my gevey sim ip4? if pwede should i change my sim tray to original o pwede ko gmitin ang gevey sim tray with the gevey chip or dapat iremove?
Sir, unfortunately you are relying on BB 4.10.01 to unlock your device via gevey, kaya po kailangan pa rin ng custom firmware. You also can't update firmware one level lower than 5.1.1 9B208 like 5.0.1 because it will require you an SHSH blobs and signing for 5.0.1 is already closed. Lastly, SAM unlock no longer works, it will only work if you have a saved SAM activation unlocking module. Kung hindi nyo po nasubukan mag-unlock using SAM from the time na working pa ito at wala po kayong na save na SAM module, di po ito gagana.
Advise ko lang po sir, please preserve your baseband by using a custom firmware and save your SHSH blobs if you need to downgrade anytime. There is currently no baseband downgrade for iPhone 4 and you are one of the lucky ones to have that baseband.
The original GEVEY™ Ultra unlocks your GSM iPhone 4 and will work for iOS version 4.1, 4.2, 4.2.1, 4.3, 4.3.1, 4.3.2, 4.3.3, 4.3.4, 4.3.5, 5.0*,5.0.1*,5.1* and 5.1.1* and must have modem firmware 1.59.00, 2.10.04, 3.10.01, 4.10.01.
I hope that helps...
