Removal of Jailbreakme 2.0 Jailbreak

Hi all.

My understanding of Userland jailbreaks like this one is that they hang around in your backup files. For example if you factory restored your iphone and then loaded your backup back onto the phone the jailbreak would be restored.

AFAIK Jailbreakme 2.0 is a userland exploit.

The faq says just restore your iphone to get rid of it, but I assume that means dont use your backup file? Has anyone tried this yet??

I would like to give it a go, but if it doesnt work out or gives me problems i dont want to have to lose all my app data to get rid of it, or go back to a really old backup file.

In the past i've always used redsnow/pwnage tool so removal was only a wipe/restore backup away.

Any help would be great,

thanks
 
ALL jailbreaks leave traces in the filesystem. They only differ in what exploit they use to gain read/write permission in the first place. So yea any backups created after a jailbreak will contain traces, but these traces are harmless.

Restore stock FW and set up as new phone. All gone.
 
Thanks,

this is what i suspected.

Its a shame you cant backup app data seperatly and restore to a non JB phone.
 
Hi guys

Today I first made a backup of my iPhone 4 in iTunes. Then I jailbroke it via jailbreakme.com and tested some apps from cydia and rock. Tried FaceTime over 3G etc. Then I decided I didn't want to go the jailbreak road so I restore my device in iTunes and applied the backup I did before jailbreak. Now that my phone is back into non-jailbreak state. Are there any traces of the jb? I don't ask because of security. Just don't want unused stuff laying around.

Thanks
 
you should always backup your iPhone in iTunes before doing any jailbreak. remember these jailbreaks are hacks and while most times you have no issues there is always a chance you will lose data when you do this. comex himself said to backup your iPhone before you use jailbreakme.modmyi.com. then you will always have a clean backup if you ever need it.
 
Even if you restore to a backup made while jailbroken, it won't re-jailbreak your phone. It'll just put some plist files and other traces of jailbreaking back.
 
I dont know if you guys got me right but as i said i did my backup before jbreak and this is the pne i restored so is my root partion or not? Thanks
 
if you wiped the phone and restored from backup which was done before jailbreak.... why are you concerned about jailbreak being left behind when you restore from the pre-jailbreak backup? you cant restore what isn't there :p

Makes me wonder if I totally got rid of the jailbreak or not.

Your info in iTunes that was saved before the jailbreak is clean. This will keep track of all of the apps & contacts & etc. at that time. If you jailbreak & decide to restore from the save in iTunes, it will restore to a non-jailbroken state. Any of the data that the JB put in should be removed or overwritten by the stock firmware. I had a JB app that wasn't working properly, so I removed it. Then, it wouldn't download correctly. Figuring that there was some sort of error, I decided to restore & rejailbreak. I decided to upgrade to 4.0.1 instead of back to 4.0. The JB & everything else I had from Cydia was gone. I then jailbroke again, & I'm back with fewer add-ons. The app I wanted doesn't work with 4.0.1, but I figured that might happen.

To make a long story short, if you decide to get rid of the JB, the Apple firmware will make any little lines of JB code inoperable.

Sigh. I'm not trying to restore something that's not there. I ask if the restore formats or wipes everything so that there are not files from the jb laying around doing nothing because being it my phone or MacBook I hate when there's stuff left that I don't use. So my concern is about my valuable diskspace
