there isn't any app that UnRoot v20e ?
maybe i decide to update in officially way.
Thank you
You can update using SmartFlash or the official LG Web Update whether you're rooted or not, whether you have CWM or not, hell, even if you have a custom rom installed you should be able to update using the Web Update tool.
I've rooted my O3D while I still have the stock 21D rom and the stock recovery (not CWM).
If I make a factory reset (from the Android menu or the stock recovery) will it unroot the phone? Is this a safe way to unroot the phone or should I unroot it with the quoted method?
I don't think it will unroot the phone since factory reset wipes data only. As for stock recovery, I'm not too sure if it will unroot or not. CWM will not unroot since it also wipes data only.
Thanks for the fast reply. So a safe way to unroot the phone is to remove su from /system/bin and/or /system/xbin and Superuser.apk from /system/apps? Or is it even more safe to unroot it by just flashing again the 21D rom using the LG Update tool?
I think removing the files is sufficient even for warranty repair. Of course, remove any apps that require root as well if you were to send your phone for warranty service.
It takes 2 reboots no longer than 8 to 10 min.
