Member: 1418143 Status: Offline Thanks Meter: 353 | How To Downgrade iPhone 4 iOS 5.1 Baseband 4.12.01 to 4.11.08 And Wait For Unlock [Gu If you have an iPhone 4 (carrier locked) and you’ve upgraded to iOS 5.1 then the damage has already been done. You have updated your iPhone 4′s baseband to 4.12.01 which is not unlockable. You cannot go back to any unlockable modem firmware of iPhone 4 like 1.59.00, 2.10, 3.10 or 4.10 but there’s still a hope for you guys to go back on iOS 5′s baseband 4.11.08, there’s no unlock solution available for baseband 4.11.08 (as of this writing) but there’s a hope for 4.11.08 unlock because all dev teams and hardware unlock manufacturers are working on an unlock solution. Baseband 4.12.01 on the other hand is a new baseband and developer are not familiar with it right now. So there’s a good chance that you will get your iPhone 4 baseband 4.11.08 before than baseband 4.12.01 unlock. You can downgrade your iPhone 4′s iOS 5.1 baseband 4.12.01 to 4.11.08 and wait for unlock which is the best option available right now. You must do it quickly because Apple will stop signing iOS 5.0.1 any moment and you won’t be able to downgrade your baseband after that. If you think “something is better than nothing” then get your iPhone 4 back on iOS 5.0.1 (baseband 4.11.08) and wait for an unlock. Note: The window of baseband downgrade is very short you must do it ASAP. How To Downgrade iOS 5.1 Baseband 4.12.01 to 4.11.08: Things you will need during this process: Step 1: Connect your iPhone 4 to computer via USB cable and make a back up of your data (recommended) Step 2: Turn off your iPhone and put it in DFU mode To enter DFU mode:
This was it folks, though your iPhone 4 will remain locked but you have a better chance of getting it unlocked on baseband 4.11.08. I found this post usefull for us ( unlockers ) so just copy/paste it / source : how to arena blog as you see in picture my own blog is : http://smartphonologie.********.com/#axzz1oVcdKdMO |
