Stock Firmware -> RedSnow JB -> Stock Firmware

[Dammit Cubs]

I wanted to know if this was an option:

if I installed the Redsnow exploit onto my iphone 4 and then I decided I didn't want it and wanted to wait because lets say I didn't like the tethered option.

How do I return the phone back to stock as if JB never happened? Is that possible?

If you have your shsh blobs saved from a prior firmware, say 4.1 then you would simply do a restore to that firmware, there are specific instructions all over the web on how to do this.

The reason why i ask is. I must of done something wrong when my old iphone 4. I erased the contents and tried to do a restore, but itunes gave me an error and I stuck with a bricked phone.

I didn't want that same scenario 6 months down the road.

How did you erase the contents?

WHat error did iTunes show?

How is your iPhone bricked?

I did it within the phone under erase all contents. Im starting to think that was the reason.

I don't know the exact error. I had another problem with my lockbutton just randomly failing and the apple store accepted it.

I think brick is a poor choice of words. I should of said, it was unrecoverable with my knowledge because using DFU mode + restore caused the itunes error every time.

Never erase all content after a jailbreak.

Never erase all content after a jailbreak.

+1.

It is the absolute worst thing to do, it will give you all sorts of problems. What you need to do is simply restore to 4.2.1 and get a fresh start. I would start phone as new, not from a backup, to get rid of all jailbroken traces on your phone. You can go to 4.1 if you have your 4.1 blobs saved in cydia.
