I'm owning a Semi untethered 5.01 iphone 4 now and I have my SHSH saved in cydia for 4.3.x using tinyumbrella but I missed the 5.0 SHSH... (Cause I upgraded my phone from 4.3.3-> 5.0.1 straight away)....
Just wondering, is it possible for me to :
1. downgrade back to 4.3.3? (I think should be no problem)
2. downgraded to 4.3.3 and upgrade back to 5.0? (possible?)
I was hoping if I could restore my phone to 5.0 for waiting the untether release. Any advice are welcome.

QUOTE(huiqing88 @ Dec 6 2011, 02:06 PM) For 1, it's possible if you had the SHSH. But not sure whether the cellular network will have problem or not due to the Baseband/iOS version mismatch (needs confirmation on this). For 2, not possible. No way to go iOS 5.0 ever again. I see.. just curious, the IP4 I owned is factory unlock set by Digi. If I need to downgrade my firmware I also need to do the downgrade for baseband too? (now is 04.11.08 and 4.3.3 should be 4.10.01) |

QUOTE(huiqing88 @ Dec 6 2011, 02:52 PM) Baseband can't be downgrade. That's why I worry it might have mismatch issue after the downgrade. (Last time I upgrade my 4.1 to 4.3.3 without updating baseband, then the phone signal will be forever 1 bar. This is what we call firmware/baseband mismatch.) I see... anyone also in the same situation like me? care to share your experience in downgrading from IOS5.01 to 4.3.3 and whether have baseband issue? |

QUOTE(bv2427 @ Dec 6 2011, 05:10 PM) Had a problem with my USB, couldn't charge with PC, only can be detected when the phone was in restore/DFU mode. So I was forced to restore. I saw a vid that had the solution to downgrade from iOS5 to 4.3.3. I did try it on my iPod touch with great success, but for the iPhone 4, I think cos my baseband got updated which is why it cannot downgrade to 4.3.3, even with custom IPSWs and what not. Couldnt detect the carrier. I think the way to have upgraded to iOS5, then downgrade to 4.3.3 is to preserve the baseband before updating, not sure about this tho.
Added on December 6, 2011, 5:17 pmCurrently on semi-tethered. Pretty stable. But don't install CameraLocker (iOS 5 Cydia tweak), that was the reason behind my random reboots. So far after uninstalling it, no reboots. QUOTE(latworx @ Dec 6 2011, 05:38 PM) i dunno if my case is cause by the downgrade. after go to 4.3.3 from 5.0, i cant mod the carrier logo, where the logo didnt change as usual. and after a day, the carrier files got prob, where my phone can't connect to edge@3g. then go back to 5.0, things back to normal. and now, i'm quite worry to downgrade back to 4.3.3 QUOTE(huiqing88 @ Dec 6 2011, 05:45 PM) Oh ya one very important thing to note before you downgrade to 4.3.3... You can't restore your 5.0 backup to 4.3.3... iTunes will not allow Hence you'll lose all of your backup settings/SMS/Contacts/Emails/Bookmarks etc... Thanks for all the reply! its very helpful. I don't think I will restore to 4.3.3 then to avoid all the hassle. |
