    I downloaded the evasi0n jailbreak about a week ago. Didn't like it, so I googled ways to uninstall it directly from my iPhone. I figured out away and Cydia is gone. There's an app icon for "Respring" and the dock doesn't show. What can I do to fix this? I backed it up to iCloud before Jailbreaking but I downloaded other apps in the meantime. What to do?

    DFU, restore as NEW, but if you are going to load a backup make sure is of one BEFORE you did the jailbreak.

    Also, Cydia is NOT the jailbreak, is just an app. If you delete it alone then your phone is still jailbroken.

    I don't get why you googled it when you could of just come here.

    I wouldn't get my new apps back though, would I?

    Just re-download from the Apple app store. Unless you're talking about apps you installed from Cydia...

    But like the others have said, if you want to get rid of the jailbreak, you MUST restore your phone through iTunes.

    Just out of curiosity, what don't you like about the jailbreak?

    Lagginess, lack of free apps, no need for further customization. Mainly lag.

    Interestingly, when I do google some type of question regarding the iPhone it does pretty quickly link me here to a related thread...

    What apps do you have installed? I've got quite a few on my iPhone 4s and i don't have any lag. Anyway, before assuming it's the jailbreak that is slowing things down, have you done some troubleshooting? It's quite possible that it is an App that is causing issues of you just have a problem with your iOS install BECAUSE of the jailbreak. A reinstall, setup as a new device, and re-jailbreak would probably fix it.

    Here is what I've got installed:

    Activator - Free, but I could do without this, but it is part of DashboardX.
    AdBlocker - Not free, but nice.
    AdBlocker Networks - Free.
    AntiTint - Free
    BlurriedNCBackground - Free.
    Browser Changer - Free.
    DashboardX - Not free, but awesome.
    f.lux - Free, and this right here is one of the main reasons why I jailbreak.
    iCleaner - Free.
    Jukebox - Not free, but a neat little tweak.
    NCSettings - Free, and this is another one I jailbreak for.
    Nitrous - Not free, but I like Chrome better than Safari and it speeds things up.
    NoCoverflow - Free.
    OmniStat - Free.
    Springtomize 2 - Not free, but awesome.

    Lagginess? Weird. I'm on a 4s and feels the same to me. Define fee apps? Are you talking about theming?

    Its not the jail-break that causes lag... period.

    Its the conflicting or badly written tweaks.

    Some suffer from using winter board.

    Personally i suffer no lag on my iphone 5.

    Like, when entering a passcode, there's lag. When opening an app, there's lag. Maybe it was a Cydia app causing the lag but who knows. It's restoring now.

    I don't have any backups from before the jailbreak. What to do?

    Actually you can restore your backup you have once you dfu-restored the phone with a fresh ios install.

    A itunes backup only contains the plist or settings files for jb tweaks and apps, small and of no consequence.

    The dfu-restore will bring back the file structure to a fresh no jailbroken state. Your apps-store apps will reinstall with your backup.

    Like said by others, any lag won't be from the jailbreak or cydia (just an app) but from some badly written or incompatible theme or jb tweak/app.

    My 4s is loaded with jb apps and tweak and no lag whatsoever.

    So I can restore it from a backup that was created today and there would be no jailbreak?

    You either do or do not have a backup from before the jailbreak. Which is it?

    Nope, you need to do a DFU-restore of the ios first and than do an itunes backup restore, 2 different things.

    1st is the firmware/ios
    2nd is settings, contacts, txt, pic, music, etc

    The jailbreak alters the device file-structure, that is why a DFU-restore f the ios is required firts.

    Do not.

    ----------

    Yeah, I did a DFU, connected it to iTunes, restored it, restored my phone from the settings pane, and now waiting...

    I never recommend what TriJet told you, especially if the jb tweaks where causing issues to your device, but to each its own.

    IF it was me, DFU and restore as NEW since you got no backups before the jailbreak.

    A DFU restore is not needed to remove a jailbreak. The whole NAND is wiped and started out as fresh with a simple regular restore. The only time a DFU restore is needed is if you cannot get your device into Recovery mode or iTunes does not see it when in normal operation mode.

    As there will be no jailbreak tweaks be installed the plist for those files will not have any function. But yes the most complete way is a setup as NEW, but that takes a bit longer.

    It's a bit more technical, DFU skips the iBoot bootloader allowing different iOS version to be restored (when SHSH's available and possible like on 5.x and previous), normal restore takes the latest firmware version only. As to avoid any conflict from the jailbreak DFU-restore is the best option.

    As the OP does not have a pre-jailbreak BU he can either go the long way or take his current BU. Problems only appear if jailbreak tweaks are reinstalled that are not compatible with the installed firmware and cause boot-loops. As he does not intend to jailbreak it really does not matter.

    yeah, but if you really want vanilla w/o flavorless additives that is the way it should be done :)

    DFU does not skip the iBoot. iBoot is loaded over USB as defined in the USB DFU protocol. With iOS devices, it's in the form of a special IPSW that is within iTunes' resource files. The OP is not downgrading his firmware. He wants the newest and without the jailbreak. A regular restore will work. With a normal restore, there is no conflict with a jailbroken device. Even on a device like the old bootrom 3Gs with a custom flashed NOR. The normal iTunes restore wipes that out and replaces it with stock as well.

    I usually don't argue with 601's and above, because most of the time they are more knowledgable than i am.

    However, all my source tell me that in DFU-mode iBoot is bypassed and that is the reason that different than last firmware is allowed on the device.

    @Intell, do you have a good technical website explaining this in detail?

    ps hijacking the threat a bit, but might be an interesting read for some of us.

    There's really no good one source for it. However, in some versions of iTunes Apple has included a Recovery.ipsw for the iPhone 2G and iPod Touch 1G. Other versions of this Recovery.ipsw are downloaded as needed. DFU mode, as defined by the USB protocol, is extremely basic. It can't do anymore more than ping the computer with information. iTunes intercepts these pings. On Windows it does this by hijacking Windows' USB stack to listen for the ping. If detected, it then loads the appropriate DFU mode drivers. On Mac OS X, this is built into the IO kext for USB control. Once iTunes loads, it downloads the special Recovery.ipsw onto the device. This IPSW is an extremely basic iBoot ramdisk that simply provides an iBoot for interacting with the device. While the onboard iBoot may be bypassed, iBoot still runs in the form of an IPSW. But on all iOS devices, as long as the onboard iBoot is able to start the device into Recovery mode. iTunes can preform a restore that is just as complete and through as a DFU mode restore.
