How to un-jailbreak iOS 9.3.3 with Cydia Eraser

Delete Cydia

Saurik has officially updated Cydia Eraser this week with support for iOS 9.3.3, which means anyone who jailbroke with the Pangu jailbreak tool now has a way to un-jailbreak their devices without using iTunes to restore and update their device.

In this tutorial, we’ll show you how and why to use Cydia Eraser to un-jailbreak your iOS 9.3.3 device.

Why use Cydia Eraser instead of iTunes?

If you want to remove your iOS 9.3.3 jailbreak, you have two choices: 1) use iTunes, or 2) use Cydia Eraser. Preferably, option 2 is better, and here’s why…

When Apple stops signing iOS 9.3.3, which is going to be soon because iOS 9.3.4 was just released, iTunes is going to force you to install iOS 9.3.4 if you try restoring through iTunes. This means that when you unjailbreak your device with iTunes in the near future, you aren’t going to be able to re-jailbreak it again.

Another factor to keep in mind is that if you’re un-jailbreaking your device so you can sell it, restoring it to factory settings on a jailbreakable firmware may increase the value of the device if sold to the right buyer.

Both Cydia Eraser and iTunes are going to put you on the “Hello” screen where you have to set up your device like you did for the first time when you bought it, but only Cydia Eraser is going to let you restore back to a fresh installation of the jailbreakable firmware that you have without forcing you to update when Apple stops signing the iOS 9.3.3 firmware.

So without further ado, if you want to know how Cydia Eraser works, let’s get right into it!

How to use Cydia Erase to un-jailbreak

If you’re ready to un-jailbreak your iOS 9.3.3 device and put yourself back at an out-of-the-box iOS 9.3.3 feeling once more, you can follow these steps:

1) Download and install Cydia Eraser from Cydia.

2) Launch Cydia Eraser from the Home screen.

3) Tap on the red erase all data, unjailbreak device button at the bottom of the app.

3) When you get the confirmation prompt below, tap on the blue Erase All button.

4) Cydia Eraser will begin doing its thing. Depending on how loaded your device is with files and jailbreak add-ons, this could take a bit. For our partially-stock jailbroken device, this process took about 5 minutes.

5) Keep an eye on the progress bar at the bottom of the display, as it will continue to keep you updated on the progress of the process:

6) When Cydia Eraser finishes its thing, you’ll see a black screen with a loading bar, and shortly after, a black screen with an Apple and a loading bar. This is iOS simply setting things up so you can activate your device.

7) When finished, you should see the “Hello” screen. Just follow the steps you see on the screen to set up and activate your device.

8) And just to confirm that you’re on iOS 9.3.3 after using Cydia Eraser, head over to Settings > General > About and you’ll see that your device was restored to iOS 9.3.3:

And that’s all there is to it!

What to do now?

Now that your device has been un-jailbroken and is on a fresh installation of iOS 9.3.3, you don’t have to worry about bugs with your jailbreak anymore.

You’re now free to re-jailbreak, or leave your device as it is. If you were planning on selling it, just turn it off when you see the “Hello” screen in Step 7 and leave it at that.

Wrapping up

With this useful tool now in support of iOS 9.3.3, you can officially un-jailbreak and re-jailbreak on demand without the need to worry about Apple closing iOS signing windows for iOS 9.3.3.

    Is there a tutorial on iDB for how to backup and restore JUST iMessages/SMS? I like to do clean restores, but I dont want to lose my messages. the only “normal” way to do it is through a full restore from backup which I don’t want to do.

    I used to have a link to a good guide on which files to save and put back, and how to change the security settings after putting them back on the restored phone, but I can’t find it.

    • leart

      nah, before iOS 9 it was possible with ibackupbot… now it is not.. the app don’t have access anymore to modify or partially restore the backup… before it was very possible … I used sms, notes and even app datas from different backups even from different iOS and restored those data to a single device .. for jailbroken device have no idea. it should be possible

      I guess since 8.3 the access to iOS apps on the device it’s closed (without jailbreak) . and probably is the same for sms or messages

      • nova voter

        I found it. It worked. I’m all set.

      • Saudor

        it should be still possible. (it definitely was in 8.3 when they locked it down)

        the sms.db files and whatnot are stored in a different area separate from the app sandboxes. (if anything, the location might have changed)

      • leart

        I give up.. tried ibackupbot when i got a iphone 6 in 8.3 and it worked to install sms, data and notes from ios 7-6-8… but when i got the iphone 6splus in ios 9, didn’t worked anymore.. just restored from the backup i prepared for iphone 6 in ios 8.3 but it was impossible to make changes to a device on ios 9… I mean without jailbreak… I quit jailbreaking ..

      SSH into your iphone in

      var/mobile/library and copy the entire SMS folder.
      if you have read/write problems, set permission to 777.

      Restore new ios (must be jailbreakable), ssh into same path and copy the entire sms folder.

      If you want to change your iPhone you can use iMazing on mac that let you clone info from an iPhone to another (you can chose what to and what not to clone). You can ssh, save app data,music etc with it. It’s an iTunes like but with way less restrictions!!

      Maybe for next time if I m too late ^^

    Saurik is a genius .. this tool is what we dreamed for a long time in the past.
    I remember that i changed the device when I messed iOS 5.1.1 back in 2013 and purchased another one in 6.0.1 just to be jailbroken 😀

  • Blip dude

    This whole time I kept thinking “Great, only works on 9.3.3” only to find out that yes I can use it on 9.3 as well.

    Another upside, technically speaking, there is no longer a real need for a PC to Jailbreak and Un-Jailbreak as long the Airplane mode trick still works when installing the Pangu app from the Jailbreakme9 website still works (Again, technically speaking), and Cydia eraser encounters no issues.

  • Alberti

    I’ve removed Jailbreak with Cydia Easer, but why i cannot download Version 9.3.4 in my iPhone?

    • Alberti


      • Try it in iTunes.

      • Julio Hernandez

        Why would you wanna update to 9.3.4?

  • (JailbreakQA) King Shoot

    If anyone is confused, Cydia Eraser is the new name for Cydia Impactor, which allowed you to do the same on iOS 8.1 through 9.0.2.

  • Guava Angel Rosas

    Amazing work from Saurik..thank gosh this tool is now available!

  • Mark S

    So I imagine this works on all 9.x version up to 9.3.3 now?

  • Clubpiee

    Help needed getting error ipad mini ios 9.0.2

  • Juan Ricarte

    I’m currently jail broken on iOS 8.3. I downloaded the IPSW for 9.3.3. Do I upgrade by using Cydia Eraser to take it back to 8.3 then update? Or just update on desktop using ISPW straight from JB 8.3 to 9.3.3?

  • Roman MacKenzie

    Is there a way to delete Cydia specifically? I restored my phone to a backup prior to the jailbreak, but that didn’t get rid of the Cydia app. So I tried a full restore to iOS 9.3.2, and that surprisingly didn’t work either, the Cydia app remained on my second page home screen. So I tried another restore to backup, and that didn’t work either. I also tried updating to iOS 9.3.4, however I can no longer update through my phone, nor through iTunes. Cydia doesn’t open either. Any help would be appreciated.

  • crazyhunter
