According to the rooting process that doesn't use the PC, this is the method to unroot. I have not tried it.
[FONT="]- open your trusty terminal app
- you should see a $ symbol, now do the following
- su
- now you should see a # symbol
- mount -o rw,remount -t ext3 /dev/block/mmcblk1p21 /system
- rm /system/app/Superuser.apk
- rm /system/bin/su
* rm /system/bin/busybox
- mount -o ro,remount -t ext3 /dev/block/mmcblk1p21 /system
- reboot your phone. Toda, no more root [/FONT]
That process is OK if all you did was root - i.e., you never made any changes to your phone after rooting - for example all you did was run wireless tether.
If you made any cutomizations, e.g., if you applied a custom ROM or a theme, or uninstalled/removed Blur apps, etc., you'll need to do more, or VZW might notice you modified your phone. (Assuming the primary reason to unroot is if you're returning for a warranty issue.)
So what you can do (actually,
should do) is, as soon as you root, make a nandroid backup of your stock rooted phone.
Then, if you want to unroot later, restore your stock rooted phone backup and then perform the steps above...then your phone will look and act like it was never customized.
You also might want to uninstall any root apps you may have installed (if you're the cautious type) like SetCPU, Titanium Backup, Wireless Tether, if you installed them before making your first nandroid backup. Not a must, as they don't prove either way that your phone was rooted or not, but might keep an uncomfortable conversation from occurring if you were having a tech look at your phone in a VZW store.
What I'm not 100% sure of is whether Clockwork Recovery could still launch if the unroot steps above are performed...however, the likelihood that a tech would launch CW Recovery accidentally is low anyway.
Finally, if you accept any OTA updates your phone will be unrooted...so don't accept OTA unless that's OK with you.
