I want to unroot for the sole purpose of doing a factor reset to my Bionic. I rooted using SuperSU. My battery life is horrible anymore and I just want to start fresh.
Using SuperSU do I go to settings and then do "Full Unroot"(Cleanup for permanent unroot) ?
I'm no pro so I just dont want to screw anything up.

Thanks all
 
thanks to the response. although I'm a noob it seemed a little overwhelming and the directions were not directed to me I dont think. I wish I could get step by step direction pertaining to my situation. you are saying to use the .246 file but that was not in the directions and I really dont want to brick my phone.
Do i really need to "flash" my phone? Why cant I just use the "Temporary unroot" option on SuperSU and then do a factory reset?


Everything you download will be to your computer desktop.
1. Download one of the FXZ files.
2. Download Motorola drivers to your desktop or use Moto helper device manager.
3. When it is done downloading click on it and install
4. download RSDLite 5.7 to your desktop.
5. When it is done downloading click on it and install
6. start RSDLite 5.7 picture
7. turn phone off
8. press and hold the volume down and power button at the same time on the phone. The fastboot menu will appear.
9. plug your bionic into your computer with the cable that came with the phone.
10. Click on RSDLite, you should see your phone listed. picture
11. click on your phone to highlight.
12. click on "..." symbol. picture
13. navigate to the 5.5.893 or 5.9.902 file location and select that file. picture
14. on the next pop up select uncompress and start flashing. picture
15. let the program run until your phone reboots. rsdlite screen will say 22/22 complete.
16. when the green android is up you are done.
17. click on the green man and log in with your google account.

Rooting an Android phone copies a number of files to the /system partition - a Superuser android .apk app, that manages which apps can run with root permission (you are using SuperSU); a linux binary called su, and a linux binary called busybox which allows command line utilities to run in the abbreviated linux environment on Android.

When you do a factory data reset, it erases the data stored in the /data partition, and in the /cache partition, but it does not touch the /system partition at all. So, if you temporary unroot using SuperSU, and then factory reset, you will end up with a stock rooted phone after the reset (because the SuperSU app, though it's [I think...] stored in /system/app on the phone, stores its data on the /data partition, like all other system apps on Android.)

So, in order to unroot, you need to get rid of the SuperSU application (not terribly difficult), as well as the /system/xbin/su and /system/xbin/busybox files (and there may be others, depending on the root method, though I think that should be it.)

If all that you want to do is to factory reset but stay rooted, just factory reset. As I said, you'll be rooted after the reset.

If you are going to flash your phone, did you ever get ICS, or are you still on Gingerbread? If GB, if you go to settings->about phone, what is the "system information" number?
 
As doogald points out, you do not have to unroot to do a FDR.
That part will work rooted or not.

I was reading between the lines of your post, it sounds like you are trying to fix some issues and you're wanting to start fresh.
Although it does sound daunting, flashing the FXZ file would be the quickest and easiest way to accomplish that.

Is there some other reason you need to un-root?

My apologies, there is an old piece of direction in that post.

13. navigate to the 5.5.893 or 5.9.902 file location and select that file.

That references the two older files that were used to recover different revision of GB.

A corrected version would read:
13. navigate to the 5.9.905 (for GB) or 6.7.246 (for ICS) file location and select that file.

Maybe dfib can adjust his post. ;)

Thanks, I forgot to change the file numbers when I updated the thread (just did). If you need help with getting through this just send me a PM it really is not that hard. I also think in your situation flashing the 6.7.246 fxz is the best was to go.
 
you guys are great and very helpful.
so why flash versus just doing the FDR?
I would like to reroot again once I start fresh.
So you mean to tell me that I can have a clean brand new phone just by doing the FDR without having to uninstall SuperSU or unroot?
But do I do the temp. Full unroot in supersu setting before FDR?

also how do I do the FDR? do I press that little button near the battery?

thanks again.
 
FDR just "resets" your system files that are already on the phone and deletes any data stored on the internal sd-card (such as apps and their data). When you flash a FXZ file it deletes everything on your phone (except whats on your external sd-card), system files included (where SuperSU or superuser app and root files are) and replaces them with new ones from the fxz (not any root file or apps). If you are looking for that fresh out of the box start from scratch feel I would flash the 6.7.246 FXZ file from the link in my signature.
