How to restore a jailbroken iPhone 4 [5.0.1]

[msdmn]

Hello !

I have an officially unlocked & jailbroken iPhone 4 running 5.0.1 that needs to be restored because it behaves in a weird way from time to time.

My concern is to be able to rejailbreak it after the restore.

Is this possible ? Even if an upgrade is unavoidable ?

The SHSHs for firmwares 5.0.1 & 5.1 are saved according to Cydia.

Thanks a lot

Wait a few more days till the 5.1.1 jb comes out.
Then restore to that and jb it.

Ok,

Thanks for your answer !

So there is no way a backup/restore can be done without the firmware being upgraded ?

As stated above, if you can wait might as well save some time and just do 5.1.1. But if you really need to restore download the latest redsnow. There you can verify your shsh blobs, stitch them, and create custom firmware.

Well just note, whether you wait or not, the method is still the same.

If you have shsh blobs for 5.0.1 then you can restore to that by using the latest redsnow but I'd wait a few more days to be JB on the latest 5.1.1 instead of 5.0.1
Up to you though.
