iPhone 3G (MB046LL) stuck in recovery mode. All restore techniques failing halfway.
iPhone 3G (Model MB046LL)
Originally on iOS 4.2.1
Originally on baseband 05.15...(04?)
Jailbroken successfully once using PwnageTool on 1/22/2011. Unconfirmed whether SHSH blobs exist.
The tl;dr version:
I believe I'm stuck in recovery mode on my iPhone 3G (Model MB046LL), with the iTunes logo and USB graphic below. Whenever I connect to iTunes, it also tells me I'm in recovery mode.
No matter what I do - restore the normal way in iTunes, or restore from a custom IPSW file - halfway through the restore attempt, the phone reboots itself and iTunes throws an error message with error 1015, saying that the phone could not be restored.
My intention is to get this phone working again, jailbroken or not.
How I got here:
1.) First, I successfully jailbroke the phone using the instructions here:
iClarified - iPhone - How to Jailbreak and Unlock Your iPhone 3G Using PwnageTool (Mac) [4.2.1]
The phone was originally on iOS 4.2.1 with the 05.15 baseband.
In step 6, the page instructions say, "During this process you can update your baseband to the 06.15 version. If you are on 05.14 or 05.15 or higher you will need to do this to unlock." I chose "Yes" hesitantly, since I was on 05.15 but wanted the unlock.
I made it to the end with Cydia on the screen and the phone usable. It was sluggish with multitasking enabled though, so instead of diving into the plist file, I decided to start this process over from scratch. At that point, I was stuck at error 1015 in iTunes.
2.) So I tried to get out of this by following the instructions here:
iClarified - iPhone - How to Jailbreak and Unlock Your iPhone 3G Using RedSn0w (Mac) [4.2.1]
I used redsn0w 0.9.6rc8, as linked from the tutorial, but it always fails on "Installing Activation Bundles" and reboots back to the iTunes logo screen. The first time around, I checked the iPad firmware option. The second time, I did not. The outcome was the same in both cases.
This phone has never been jailbroken before, so there are no SHSH blobs (unless that very first successful jailbreak automatically created one for me). But remember, I was going from 4.2.1 to 4.2.1 again.
Again, all I want to do is to have this phone operational again, even if not jailbroken. I'm open to ideas. Thanks for reading all the way through!
