How to Unroot Droid Razr!

If you are going to take your rooted Droid Razr back to Verizon for warranty replacement or even refund, you can easily unroot your Droid Razr back to completely stock.

Step 1. First you will need a rooted stock ROM.  This is basically the state where you rooted your phone on a stock Droid Bionic.  If this is the case, follow Step 2.  Otherwise, I hope you made a backup of your rooted stock ROM and you can restore to it.

Step 2. Go to Settings->Applications->Development and make sure USB Debugging is checked on and connect your Droid Razr to your computer via micro USB cable.

Step 3.  Download and unzip, you should get a folder called adb.  Make a note of where you unzipped it as you will need to use command cd to browse to it in command prompt/terminal.


Step 4. Open up a command prompt or terminal.  For Windows, type “cmd” under Start-Search.

Step 5. Use command cd to get into the adb directory.

e.g. For Windows:

cd \adb 

For Mac/linux:

cd Downloads/adb

Step 6. Type this to get into adb shell:

For Windows:

adb shell

For Mac:

./adb-mac shell

For Linux:

./adb-linux shell


sudo adb-linux shell

Step 7. Copy and paste the following to mount your filesystem as read/write:

mount -o rw,remount -t yaffs2 /dev/block/mtdblock3 /system

Step 8. Type the following to erase Superuser and root:

rm /system/app/Superuser.apk

rm /system/bin/su

rm /system/xbin/su


Step 8. Reboot and you should find Superuser app gone.

Step 9. You can now reboot into stock recovery to erase all your personal settings and apps.  Turn off your Droid Razr.


Step 10. Hold down both Volume Up and Volume Down buttons then press Power button and let go when you see black and white menus.

Step 11. Choose “Recovery” by hitting the Volume Down button once then hit Volume Up button once to get into stock recovery.

Step 12. If you see exclamation mark, hit both Volume Up and Volume Down buttons at the same time until you see blue menus.


Step 13. Choose “Factory Reset” using Volume buttons and hit the Power button.

Step 14. When that’s finished hit the Power button to reboot.

Step 15. When your Droid Razr reboots, your phone should be fully unrooted and back to completely stock!  Congrats!

    • Matt says:

      You need to link the files. so, for instance, if you saved the adb file to your program files folder in the C drive youre command will be “cd C:\Program Files\adb”

      • Brandon says:

        i am using a mac and after i type cd downloads/adb that works but then when i type./adb-mac shell it says no such file or directory. Please Help!

        • Brandon says:

          downloaded from this site and now can get two steps further, now when trying to copy and paste mount -o rw,remount -t yaffs2 /dev/block/mtdblock3 /system, it says operation not permitted. help!!

          • Brandon says:

            keeps saying device offline even if i unplug and replug the usb

          • chad says:

            you have to type “su” before you do step 7, watch the video at the beggining of the page and it will show you, he skips a step in the numbered process, but in the video he shows it

          • Brandon says:

            Thankyou that seemed to work, but when i rebooted the super user app is still there as well as sqlite editor and what not? how do i get rid of those? do i just have to continue and go past step 8? please help.

    • Tony says:

  4. Alphonsus says:

    Works Great! Thanks for the info, + thanks for the video, it saved my A.$.$. You forgot the # su command on your written steps. su command should be step #7.

  5. estevan11b says:

    the adb file will not open i evan installed some drivers and it still doesnt go. what can i do to make it work

  6. chad says:

    says operation not permitted while trying to do step 7

    • benmorgan says:

      same thing. says “operation not permitted” at step 7. Does it make any difference that this is “umts”, that it’s the GSM Razr?

  7. j says:

    can someone post a link to the a website for I am not finding it with the shell in it. I am using a mac. Thank you in advance.

  8. Neill says:

    took a while to find where i had adb installed (came with the rom i installed i believe), but once i did, it worked. back to factory. Great vids, keep them coming!

  9. Mel says:

    Help, when I type the su command I still don’t have superuser privledge to run the rest of the commands. I notice he starts out shell@cdma_spyder, types “su” and goes t root@cdma_spyder and I never see the # sign and can’t execute any of the commands. I’m tried running the cmd.exe as Administrator. Any suggestions?

  10. Grant says:

    having same issue…ran the rm commands, however superuser and editor and ti backup are still on the phone…please help

  11. Chris says:

    Please help!! I want to put my phone back to stock and I tried everything now. I can not get it past the simple step of typing adb shell. Im running windows. It just says device offline. I tried unplugging it and plugging it back in, rebooting, and other things. Reloaded drivers. Also tried it on two different computers and it still hasn’t worked. Im desperate, any help would be great.

  12. Chris says:

    Nevermind I got it

  13. Rick says:

    Ihave unrooted my phone & everything went well. When I rebooted the safestrap recovery is still there. I hit the serch button to by pass & everthing was back to stock except for the safestrap & there were still some files on the internal storage & SD card. They were the titanium back up & the safestrap. I just removed them everything seems fine. So I rebooted again & safestrap recovery is still there. If you by pass everything seems to be working fine But I would like to know how to get ride if the safestrap. I will not be able to take the phone in with this on there.

  14. Rick says:

    Just wanted to let you all know I got ride of safe strap. When you boot go into safe strap go to advence & disable. I did this & rebooted & no signs of safe strap. right now everything is back to stock no signs of anything root to include safe strap & all is working well.
    Zedo I want to thank you for all you inctructions & videos they are great. Keep it up. Hope to see some new posts on the Razr soon

    What is the password for SU when using MAC? Stuck on there

  16. Jason says:

    Worked like a charm. had to look at your screen shot to see the missing “su” command though, but then it was all good!

  17. Larry says:

    I rooted and did the permission fix on the tether wifi. If I unroot without doing a complete restore, the wifi tether should remain the same right?

  18. khairul says:


    I got this error
    C:\Razr>adb shell

    * daemon started succes
    shell@umts_spyder:/$ su

    On what i see is, the different of umts and cdma ..
    Someone please help to advise !

    For those of you who are using macs to unroot your phones, and your adb-mac file isn’t working (keeps saying permission denied), there are 2 fixes I found:

    1. Download the adb file from the Android SDK. Go to and download the mac version. Unzip, open the folder, go to “tools”, and click “android”. This will open the actual SDK UI. Once there, download the platform tools. Once downloaded and installed, go back to the folder you originally unzipped, and you will see a few new folders, with one labeled “platform-tools”. Go in there, grab the file labeled “adb” and place it wherever you want. Follow the instructions on this site and use this adb file instead of the one provided, and it should work perfectly.

    2. The mac tool that this site uses to root the phone is based on a Windows tool made by DooMLoRD, with some modifications to make it compatible with mac. This same author also developed an unroot tool for his method. If you have access to a Windows computer, all you have to do is download the unroot tool, install the drivers for your phone, and run the tool. Here is the xda-developers thread with the tool and instructions: I tried it, and it works perfectly. It deletes the busybox modifications as well as removing root and superuser.

    Also, for some reason, I was never able to completely get rid of the Superuser app. Even after using ES File Explorer to delete the app from the system folder, it would always still be there once I restarted the phone. However, once you use this site’s method to do a factory restore, it will be gone for good, and there will be no traces of ever having root.

    I hope my 2 hours of anguish, despair, the coming to terms with the fact that I could never bring my defective RAZR back to Verizon, and eventually figuring everything out helps my fellow mac users. Enjoy!

    • Phred says:

      My hero!

      Option 1 worked for me. I did have to be smarter than the computer though, which was tough. “./amd shell” instead of the original instruction’s “./adb-mac shell” command. Plus I had to give the su command to get superuser access.

      I mention this merely for the benefit of others. NOT to take away from any of the genius that is cchalk0


  20. Cory says:

    Is there any way to unroot it to the way it was before? Not back to default.. Thanks

    • cchalk0 says:

      From what I can tell, Superuser will not come off of the phone unless you wipe the device after unrooting. I tried deleting Superuser.apk though ES FIle Explorer and ADB, and the app never completely went away without a full wipe. I’m assuming it puts some other entries in the system folder, besides just the app, that keeps it there, but I don’t know what those are. Maybe if you do some digging on google, you can find them.

  21. kevin says:

    i accidently updated my phone and it took away root but left superuser app on my phone and wont let me get rid of superuser or reroot my phone what should i do?


    • christian says:

      @kevin i was in the same boat i just did a rsdlite back to the old software and ran the windows unroot tool and I’m doing a factory reset now to see if the su app is gone ill let u know

      • christian says:

      • daniel says:

        where did you get the rsdlite file from? the link i get from xda-developers isnt working. ive tried cliking on it and right clicking on it and i still dont get anything. my razr is defected so i need to remove the su app so i can return it.

      • kevin says:

        what is the rsdlite? i cant find out how to get back to the old software

  22. scott says:

    I keep getting the “operation not permitted” in adb. Can’t seem to find my way around it.

  23. estevan says:

  24. Anders says:

    Please help!
    I have already completed this tutorial a few days ago successfully, but I tried again today because I was having trouble with the superuser not functioning properly on the phone and I get this error message in the process. I have no clue what to do next.

    shell@cdma_spyder:/$ mount -o rw,remount -t yaffs2 /dev/block/mtdblock3 /system
    mount: Operation not permitted

    Thanks for any help available

  25. Collin says:

    i need help with this guys. i made the mistake of making my razr boot to recovery every time like instructed in a rooting tutorial. i need to take it in and obviously need it completely unrooted. i followed these directions and got rid of su and then did the factory reset. so all unwanted apps are gone, but im still booting to recovery. i have read that i need to root again and disable this through the bootstrap program. but i am unable to root my phone again for some reason. any help is appreciated. thank you all

  26. Kev says:

    I’m stuck at Step 6. Typed in adb shell and got the
    error: device offline
    I’ve tried unplugging the USB cable, using a different cable, tried all the USB connection mode and still nothing. Is there something that I missed?

  27. Rick says:

    How do I unzip the adb file. I know this is a stupid question but need to know before I root my Droid Razr.

  28. Rosemarie says:

    I rooted my Droid Razr several month ago and everything was fine until three days ago. Now i don’t get 3g or 4g on my phone. I really don’t want to have to unroot it. I tried the *228 doesn’t work. turned it on and off nothing.Can you help me please

  29. God says:

    Worked perfectly, zero problems. Thanks for the instuctions!

  30. Ryan says:

    Where is the link for the download?

  31. hank says:

    couldn’t be easier but also locks out future OTA updates from verizon

  32. hank says:

    let me correct statement
    it’s not the unroot that blocks updates its the rooting method that does.
    how do you unroot without losing data for future V updates?

    for those that don’t know *228 does not work on razr droids, they only update OTA when V says so.

  40. Kyle says:

    Please guide me about for 3 errors and what do i can.

  42. Felipe says:

    Solution if you still have SuperUser app!
    If someone still have the Super User app after Unroot and reboot the phone, just reboot again as shown in the 5:10 of the video and INSTEAD of choosing “wipe data/factory reset” (6:25 of video) chose “Wipe cache partition”.
    After that, chose “reboot” and Voilà!!
    At least that worked for me…
