Hiyas all,

I have an iPhone4 with iOS 4.0.1 unlocked via jailbreakme.com.

I had some problems with my carrier settings, and tried to factory reset my phone, to see if the problem would be solved. Sadly, I was not aware of the fact that this is not a "healthy" thing to do on an jailbroken iPhone4, so right now my device is just stuck into the boot process.

I can put the device into DFU mode, but unfortunatelly, when I bought my phone, it was already too late to save the SHSH 4.0.1, so I can't really restore the firmware to this version.

So, I have two questions:

1) Why can't I factory reset an iPhone4+jailbreakme.com to factory settings?

2) Is there anything I can do restore my iPhone to a working condition (besides waiting for an updated pwnagetool, which would allow me to build a custom 4.1 firmware)?

Thanks in advance,

Domingos

This is a difference in expectations - the feature "erase all content and settings" works as advertised, however people aren't well educated on SHSH and how that can be used to force users onto the latest iOS version.

Did you save a SHSH at all? 4.0.2 for example?

Also, as you have an iPhone 4 - you might be able to take advantage of the "feature" in TinyUmbrella to block baseband upgrade when restoring to iOS 4.1 (which Apple will sign right now).

I haven't fully thought this through - if it is possible for your phone in it's current situation - to use this feature. So don't rush into trying it straight away.

"Yes" and "No". I have saved a SHSH, but I believe its 4.1, so the only restore I can do will remove my unlocked baseband.

I was not aware of this "feature".

That might work for me, as I can wait to be jailbroken again. Right now I only need a working iPhone (that is, one which is activated and unlocked).

One thing is that was I not able to figure how to use this option with TinyUmbrella. I'm running version 4.1.5 on windows, is there a diferent version I should use?

Again, thanks in advance,

Domingos

Nothing like doing some research in advance.

The Firmware Umbrella: TinyUmbrella with 4.1 Support

and

iPhone 4.1 Upgrade: Retain Original Baseband Unlock [Tutorial] | The Apple Press

Lets see if this works for me.

Luckily, I was wrong, and in fact I had SHSH 4.0.2 saved (I also saved the version 4.1 now).

Now I successfully restored my iPhone to 4.02, while (in theory) still retaining my unlocked baseband.

Right now I'm still finding some issues while trying to activate my iPhone (which is kinda strange, since I have an unlocked baseband). I'll try to lend a simcard from a friend, to see if it solves my problem.

Thank you all, and see ya.
