iphone4 stopped working, only dfu mode or plug into itunes mode

[Melei]

I recently jailbroke, a few days later my phone simply stopped working and only goes into DFU mode. I tried a myriad of recovery methods. I didn't back up my iphone info. I have no idea what to do I can only enter DFU mode, nothing else. It doesn't register under tinyumbrella, not that I would know how to use that program anyways. Once while in DFU mode, I manually installed 4.2.1 but during the end when it looks like my iphone is almost finished with recovery it says BLAH BLAH IT UNEXPECTEDLY DOESN'T WORK(10) ((

If it was me I'd try a restore in iTunes to get the phone back up and running.

If it comes back up you can just JB it again.

Hang out though someone with more experience might be able to help you get it back up and running without losing the stuff that isn't backed up.

PS... you should always, always back up in case something goes wrong.

I tried restoring through itunes as well and still a no-go. I also just tried jailreaking again with limera1n to no avail. It says successful jailbreak but my iphone is still on the " usb to itunes" screen.. thanks for the advice though.

Exactly what happened when you tried the restore? What errors etc. did you get?

[Melei]

the iphone could not be restored. An error occurred.(21)

Dunno if you have tried this, but I just googled that error.

Two people fixed it by doing this...

Step by step for mac users..

1. Go to Disk Utility: you can just type this in spotlight or open Finder, click on Applications, open the Utilities folder, double click Disk Utility

2. Click Macintosh HD

3. Click Repair Disk Permissions: this will take awhile but I didn't have to delete anything from my laptop after this

4. Once permissions have been repaired, unplug iPhone from the laptop.

5. Reboot iTunes.

6. Plug iPhone back and turn it on.

7. Restore and update.

8. Fixed with no loss of files.

tried that as well, now I'm getting the 1013 error at the very end of the "verifying firmware" part..

Are you restoring to 4.2.1? It should verify the firmware if your downloading it through iTunes. If your trying to restore to 4.1 then you need SHSH's for that firmware.

When you got the the connect to iTunes page after you tried jailbreaking with limerain I'm assuming you were on 4.1? If so did you try tinyumbrella to kick it out of recovery...?

[Melei]

when i kick it out of recovery with tiny umbrella it shows the apple logo for a minute and then goes right back to recovery mode.

and yes im doing 4.2.1, still won't verify through itunes
