I know beta 1 was downgradeable. Anyone with beta 2 tried?
They will all be downgradeable. You just have to put your iDevice in DFU mode and click restore in iTunes, since Apple is still signing iOS 4.3.3 and its baseband.
Nice! Thanks for the quick response. Silly question - why then could we not downgrade previous betas since Apple was still signing the current version back then?
you don't even have to put it in DFU mode, I'm restoring 4.3.3 right now
I think the baseband changed? but I'm not sure
i hate when i sound like a dumb noob but i too was wondering how to downgrade beta 2 to 4.3.3. Im using itunes beta 2 and i put my phone in DFU mode but after a long wait, i get the dreaded 1603 error. Any help on what to do?
I downgraded my iPhone and iPad last night using iTunes 10.5 beta 2 on my iMac. Here's what I did:
1) Put the device into recovery mode (not DFU mode) which I did because I was too lazy to locate the firmware myself
2) When iTunes started up telling me I had a device in recovery mode, I clicked Restore and confirmed that I wanted to restore.
3) There is no step 3: That's all I did and it worked fine
Been to beta 2 and back twice now, and will be staying on beta 2 as it's far smoother than 4.3.3 from my experience.
I got a copy of iOS 5 Beta and Beta 2 from a Friend who's a Developer. So they are legit copies with updated hard ware numbers. I am trying to go back to 4.3.5 for a couple reasons...
1. iOS 5 is buggy and most apps don't work that i use on a regular basis
2. It expired today and I can't get a copy of Beta 3 for a week or so, so my phone is useless..
I try and follow your steps to go back to iOS 4, and it says that I am not eligible for the requested build.
Apple isn't signing 4.3.3 anymore, you MUST downgrade to 4.3.5
maybe other people should have said the most recent public iOS release a.k.a. 4.3.5 not 5b4
