    Hi Guys,

    Now that we know 6.1.3 is unjailbreakable at the moment, those of us with iPhone 4S or 5 devices who have saved blobs - are we able to do a clean restore of 6.1.2 if 6.1.2 is already installed?

    I gave it a go the other night and only got "iPhone is not eligible for the requested build", even with the hosts set to Cydia or using TinyUmbrella's TSS server.

    I guess that there is no way to restore to a factory 6.1.2 now for a clean jailbreak?

    Cheers,
    Nick

    No, well known that blobs don't work on 6.x for A5+ devices.

    Lucky I backed up my LaunchDaemons folder before removing the software update plists!

    Well, all current jailbreakers are terrified of being forced to go to 6.1.3. Install just one wierd Cydia app, and blammo! you now have to install 6.1.3 to unbrick.

    Really?
    Why you place your device into safe mode and simply delete the offending tweak?

    there's always the chance that one of the tweaks will mess up some sort of system files (or whatever it does that doesn't use mobile substrate) and cause your device to not even be able to boot up in normal, safe mode, or mobile substrate disabled and the only way out is to restore

    I have always been curious why the "Erase All Contents and Settings" feature doesn't work after a jailbreak. This would be so great if that still worked, anyone could just easily, right from the phone, go back to a stock version of whatever version of ios they sre currently on.

    I believe the reason it doesn't work because Cydia modifies the file system when you first run it after a jailbreak.

    Makes sense, but why couldn't someone build in a way that it changes it back somehow?

    my guess is that the original file system is not compatible with the way how cydia packages can be installed. And I don't think there was such a button to "erase all contents and settings" in the earlier iOS's. I'm not too certain about this last part though

    i did some googling and found this for you: http://forums.macrumors.com/showthread.php?p=13994720#post13994720

    looks like it needs to change permissions from read only to read and write as well as move the files elsewhere so this essentially means you are missing all the system files when you click erase all content and settings.

    it erases everything in the "media" partition but has missing necessary files that are supposed to be in the "system" partition to boot up which explains why it gets stuck at the reboot loop. or, that's one way you could look at it.

    Interesting, it's amazing what's involved in something that can seem so simple looking at it from the users end. I just plug my phone in and click the Jailbreak button, nothing to it:D. Thanks for the info.

    Truth! It actually is pretty worrisome.
