Factory Reset then Update

[the9thwonder]

So my Droid 4 has been getting slower and slower, there is always garbage running on it. I have rooted it, but I can no longer freeze apps after updating to Jelly Bean.

I was thinking about doing a factory reset, then updating the OS, then installing any apps I wanted.

A few questions :
- when doing a factory reset, what OS version will the device go back to?
- if there a way to disable the auto-download/install of apps I have?

Or, do I need to write down the apps I have/want and uninstall all of them before doing the factory reset so they don't auto-download?

Thanks!!

A factory reset simply erases the device memory and leaves the ROM/OS in place. You'll still have the current OS version except it will have no user data. When you log back into your phone make sure to not check the "backup to Play store" (it might say something else) feature during the setup process to prevent apps from auto-installing. Since you are rooted, you can use apps to backup your apps+data and restore what you want to use once the phone is all setup. I use Titanium Backup for this.

Hopefully this cleared up your questions. Let us know if we can be of further assitance .

I'm assuming that the root function will be lost after the reset?

no, factory reset/data wipe does not unroot

After I updated to JB, I re-rooted. But I lost the ability to freeze apps. Should I have un-rooted and then done a fresh root?

Sorry for all the questions.

device is either rooted or not,
first get 'root checker basic' to confirm root status
if it says device is rooted, it's titanium backup (you need the pro version to freeze apps) or whatever you are trying to use
if it says is not rooted use http://vulnfactory.org/public/razr_blade.zip
may need to read xda-developers - View Single Post - [Q] Unable to properly root after 4.1.2 OTA update.

Thank you sd_shadow.
That will give me something to do this evening. Yes I lead a very boring life.

So, Root Checker Basic came up negative. Some how I lost root access, probably when updating the OS (but that's just my uneducated guess)

Aren't there other applications that can freeze apps?
I was using App Quarantine ROOT/FREEZE. Until now I saw it in my list of apps.

I have SuperSU and Superuser listed in my apps, how do I get rid of those?

 

[sd_shadow]

yes you lose root with updates, you have to reroot to remove superuser
may be able to freeze or hide using menu options
menu button>manage apps

edit: click on app you don't want, select disable
