Unroot

There may come a time when you need to unroot and revert to stock. I know, I know… hold back your tears. The good news is, it’s possible. The bad news is, if you’ve flashed your radio, it’s a bit more difficult. However, it’s still a pretty simple process. Obviously, this will wipe out all apps & data, so make a backup if you care about anything. I’d recommend downloading an app called MyBackup to your phone, and do a full backup of apps & data, since you can’t use Titanium Backup after you unroot.

My standard disclaimer applies.

If you HAVE updated your radio, AND installed unrevoked forever on 2.2

    1. Make sure that your SD card is formatted FAT32. Download this PB31IMG.zip (Thanks Adrynalyne) which contains all parts needed to get you stock (minus changing S-off back) to the root of your SD card.

    2. Boot into HBOOT, by powering the phone down, then booting back up holding the Volume Down + Power buttons.

    3. The phone should see the img, and ask you if you want to update. Say yes.

    4. That’s all.

If you have NOT updated your radio, and are on 2.1

    1. Make sure that your SD card is formatted FAT32. Download the 2.1 stock RUU PB31IMG.zip to the root of your SD card (you can find this on xda).

    2. Boot into HBOOT, by powering the phone down, then booting back up holding the Volume Down + Power buttons.

    3. The phone should see the img, and ask you if you want to update. Say yes.

    4. That’s all.

If you HAVE updated your radio, but did NOT use unrevoked forever

    1. Download the zip in this thread (there’s also a great video there) to your computer and extract the flash_image & mtd0.img files to your sdk tools directory. See my rooting guide if you don’t know what this is.

    2. Boot into recovery

    3. In recovery, go to mounts and storage, then select mount /system

    4. Connect your phone to your computer and open adb

    5. Execute the following commands:

    adb push flash_image /data
    adb push mtd0.img /data
    adb shell
    chmod 777 /data/flash_image
    cd /data
    flash_image misc mtd0.img
    exit
    adb reboot oem-78

    6. When you see the silver HTC screen go ahead and pull your battery to shutdown.

    7. Make sure that your SD card is formatted FAT32. Copy PB31IMG.zip to the root of your SD card (This should have been in the download from step 1).

    8. Boot into HBOOT, by powering the phone down, then booting back up holding the Volume Down + Power buttons.

    9. The phone should see the img, and ask you if you want to update. Say yes.

    10. That’s all.

  1. I’m a little dense(r) this morning. I rooted (unrevoked3)then unrevoked-forever. Now I want to unroot, but leave s-off installed so I can receive 2.2. Method 1 does not talk about s-off. Method 2, talks about s-off AND updated radio. As near as I can figure unrevoked3 and unrevoked-forever did not change radio, just s bit. Which mothod should I use?

    Thanks

  2. If you have not done your radio, all you need to do is the first option. You do not remove S-OFF, as this is what allows you to reroot later. Just search for the thread “HowTo UnRoot Incredible by downgrading” on android forums. Download the file from one of the 3 download links. Follow the steps in the first option here. Note that this will wipe your data.
