How-To: Revert back to NoDo from Mango Beta

July 22, 2011 36 Comments

Okay so you’ve got your Mango going, sliced the fruit into a few pieces… but you realize the fruit isn’t as ripe as you would have liked. Boy I love analogies. Not satisfied with the pre-release version of Mango 7.5? This post is for you.

I took the plunge and loaded the beta version of Mango on my Samsung Focus for a few weeks. Yes there were many fun new features to enjoy but I just couldn’t accept that it had broken a few of my most used apps. Regardless, reverting back to NoDo is necessary if you would like to update to the much anticipated Mango release sometime (hopefully sooner than later) this fall.

Follow the below steps and get back to NoDo:

1.       Be sure to have version 4.8 of Zune installed

2.       When you made the leap to Mango, a copy of your current NoDo state was copied to a folder called PreMangoState. The file (which is a long numbered/lettered file) inside the PreMangoState folder is what you will need to copy to:

C:\Users\username\AppData\Local\Microsoft\Windows Phone Update\

note - the username in the above path will be your personal username that you created for your PC

3.     Once the copy of your NoDo file is stored in the above path, open Zune

4.     Connect the device to your computer

5.      In Zune, go to Settings->Phone->Update

6.      Select Restore and follow Zune’s instructions to take you back to NoDo!

I of course take no responsibility for any mishaps you encounter along the way. But since you fine folks were capable of updating to Mango, the downgrade should be a walk in the park. Be sure to leave a comment and tell me how it goes!

 

Update: Restoring might take a long time for some users. Do not panic if you are stuck at 0% for awhile. I could’t replicate the long wait times but some users have (hyde13) – Thanks CACI_IMS

    Anyway you can upload your PreMangoState folder mine appears to be empty. Somehow it backed up nothing and now I’m stuck with Mango and can’t connect my phone to Zune to sync anything.

      have you searched your c:/ drive for the premangostate folder?

      • David D.

            so your premangostate folder is completely empty?

          • Bcampbell2858

            Completely :(   At the end of the update.bat….it said:

            Copying phone backup to C:PreMangoState
            File not found – *
            0 File(s) copied
            ===
            Backup copied to C:PreMangoState
            This will be needed when you revert back to NoDo
            ===

            But again…folder is completely empty

          • Bcampbell2858

            Quick update:

            Fortunately, my original backup generated by Zune had remained untouched by the zune beta upgrade.  I was able to restore to  Build 7390 with no issues.

    • Anonymous

      so when you connect your device to Zune, it doesn’t give you the option to restore?

      what version of Zune do you have installed?

  • Trtrask

    I’m having trouble trying to find where to past the file to. Can’t find it at all

      Make sure you can see hidden files and folders. You can check this box under options in Windows Explorer

  • grayson

    Restore Point never shows up as well as the directory for the update.

    Hello. I have an HD7 running 7712 and I want to downgrade to NoDo, but I lost my backup. Please help!

    • Anonymous

      You need to find a ROM, which flashes your whole device.

    • Anonymous

      After you started Zune (not going to the update section just yet), copy your backup file again in *userprofile*AppDataLocalMicrosoftWindows Phone Update (because you will probably see it has been deleted, it happened to me). Once copied, go to the Update section and you will see the restore button. Good luck!

  • Egitchon

    I have Zune version 4.8.2098.0, but there is no option to restore

  • http://www.facebook.com/profile.php?id=1109700179 Jez Sam

    there is no option sayn ‘restore’…:/ wat shld i do??

    • mho

      Hi, I did not have restore option either. Then I renamed the existing “restore folder” by add “-old” to the end of folder name. Then copied backup from by separate drive and then restore appeared in Zune.

    alright here i figured it out…

    1) Copy your backup in C:PreMangoState to *userprofile*AppDataLocalMicrosoftWindows Phone Update
    2) Run Zune, navigate to settings, click Update, and press Restore

  • CACI_IMS

    thanks buddy, worked eventually. Luckily I saw the path you listed here before I tried the mango update. I copied that folder after Zune finished backup prior to update. Backup is like almost 8gb phew!
    Anyways, my update removed chevron unlock so in the process of restoring as we speak.

    Hopefully it does go back to its chevron unlocked state eh.
    :)

    • CACI_IMS

      well maybe spoke too soon? it has been stuck on step 2 restarting the phone for well over 30 mins now. That does not sound right to me.

    • CACI_IMS

      Took a risk, manually restarted phone, zune then moved onto next step after phone restarted but then stuck at 0% :(
      oh well, gonna try tomorrow now, uninstall zune, install again,reboot, usual palarva, see if that makes a difference

    • CACI_IMS

      ok, sorted.

      I reinstalled Zune, rebooted and went thru fine. I read somewhere it can take a long time on the early steps so no need to panic.

      Maybe you should change your blog to say this

      Step 1 Preparing. Expect this to take some time
      Step 3. Restoring, stuck on 0% for ages

      this is the norm, no need to panic

      • http://wp7connect.com Hyde13

        I am very glad that you finally got it all figured out  :)
        I was rooting for you lol

        I’ll add that to the post in a bit…  

        • CACI_IMS

          cheers :)

  • CACI_IMS
