After root issues - Nexus 4 Q&A, Help & Troubleshooting

After I rooted my n4 and I'm in stock rom with no mods or anything just cwm and unlock bootloader plus root. My phone will turn to a black screen and reboot is this normal?

no.
it could also be an app, among other things. have you tried if after a factory reset, and a minimum amount of apps, it still continues?

No I haven't let. I only have a few apps downloaded. Including ROM manager and that's about it oh ya and Skype cud that be the issue?

it could be possibly. could be rom manager as well(or other root apps). is there a certain situation when this happens? do you have the superuser or supersu app installed?

It happened once when using Skype and once when browsing the web and I have the super su app installed

It happens to me sometimes due to a faulty kernel. It happened on stock too though. It shouldn't really be a problem and doesn't happen often to me. It went away after a day or so anyways.

try this, just as an easy possible solution.. boot into your custom recovery and wipe the dalvik and cache, nothing else, then reboot.

How to remove root (un-root) device without clearing apps and data?

I have an app that refuses to run because my Nexus 7 is rooted. So I would like to remove root and keep this app installed.

Not tried it my self but on SuperSU Play description it says that if you uninstall it, you will lose root:
NOTICE: A SPECIAL PROCEDURE IS NEEDED FOR UNINSTALLATION. IF YOU DO NOT LIKE THE APP, DO *NOT* JUST UNINSTALL IT, YOU *WILL* LOSE ROOT.
I would guess that if you have Super User installed, it would do the same thing.
I tried the "temp unroot" function of the superuser app and the app still recognized the root and refused to run.
I will try un-installing superuser now. Thanks for the idea, I will report back.
Sent from my Nexus 7 using xda app-developers app
Some applications I believe look for the superuser application by name. So if it sees "superuser.apk" on the system it won't run. However, I know some in the past were able to be worked around by renaming the superuser application.
I don't know if this is still a valid method, but...yeah.

Try an app called OTA Root Keeper (voodoo). It will temp unroot. You then need to normally force close the app you are talking about and the run it and it should work.
When you are done if you use a lot of root apps you can the undo the temp unroot and be back to full root.
Some versions of su have that ability now too but I've not tried them yet... don't really have anything that cares if I am rooted any more.

I've tried using the temp-unroot feature of the superuser app and I was not able to do so. I wish I knew what this app was looking for.

Download supermanager from playstore, enable the root function in settings. Swipe over to tge next screen and select uninstall apps and uninstall superuser. Then reboot. That should do ut.

What app is it?
Sent from my Nexus 7
The app is called Jeppesen Mobile TC and you will only be able to download it if you have a 9-10 inch tab with honeycomb or ICS running. I managed to get the apk so if someone wants it to try please let me know.
I will try the above shortly. Many thanks!

I just tried this and it seems to have removed root like you said yet the application still thinks I have root. I un-installed the app and reinstalled it after rebooting.
The app runs fine on my gfs Nexus 7 which has never been rooted.
Hmmmmm

Hello. Can you explain the process you followed to make this app run in a Nexus 7. Because I downloaded the apk from a russian site in my Nexus 7 (non-rooted) and after the installation the app ask for me my name and activate number and I can´t do anything more.
Thank you for the help!

Jepp is subscription based. You need to buy a subscription to use the software.

Works fine for me, Stock, rooted, unlocked boot loader, Franco kernel.
Maybe you have a defective phone?
You haven't frozen anything in Titanium Backup or uninstalled anything?

Wrong
Looks like they moved my original link so this is a direct link http://suipre.com/8310b8
If you download from the link using your prime use chrome browser. Stock browser didnt work for me.
There is an update in the play store after this. Do not install it or you will be back to not working.

Touch screen had become unresponsive on bottom of screen please help!

I flashed my third ROM using twrp 2.6 and it worked fine as usual but I went to update the rom and flashed the zips it went through alright but said I lost super user access and to swipe to fix so I did but it didn't work just rebooted back to recovery and after a Bunchve tries I finally just unrooted my device completely using qbking's method and it unrooted my device but it is still unresponsive on the bottom of the screen but only on certain apps and the keyboard. Can someone please tell me what I did wrong?? And is there anything I can do to fix this?? Need help ASAP :/

Download the MF9 tar file and install through odin to return to stock and start over unless you have a nandroid you can restore. Sounds like there is something corrupted in your files and it will be better to start from scratch.
Thanks can u give me steps on how to do that and should I run the pit file in Odin too? I saw that some where

Have you tried this with other tw roms or aosp roms? Also you might want to downgrade to twrp 2.5.0.2 since 2.6 is a bit buggy
Edit: here is the link for twrp 2.5.0.2 I got it from sacs rom
https://www.dropbox.com/s/2c9fqr1b8q63cjt/TWRP-Recovery-jfltespr-2.5.0.2.zip
Just flash it in twrp and your good to go
Also flash kernel to see that is also the problem.

So I should try flashing another rom to see if it fixes the problem?

Try going to the dialer and typing *#0*#
This will bring up a test menu. From here you can test the touch screen.
After flashing a new rom rry it as well. This will test if it is the rom or not too. If it works theee but not ar other times it is probably the rom.

For messages not sending, I assume you're connected to your carrier's data network. If not, it's probably a radio issue.
Assuming everything is okay with your carrier, I'd try resetting your APN settings. Under Wireless & Networks click on "More..." followed by "Mobile networks" and "Access Point Names." Following this click on the three dots in the top right, reset to defaults... restart your phone and report back. :good:
Didn't work..

Chances are there's a mismatch somewhere. I'd do a complete restore using the factory image from Google and go from there
I download the factory image from Google and it shows up under downloads but won't show up on ROM manager or in recovery its like it didn't download.. But ik it did

Why not just use a file explorer with root rights to uninstall system apps by going to
/system/app and deleting it?
Odds are you'll have a file explorer already.. don't see the point in an entire separate app just for that purpose.
You can't do that when it is preinstalled into the framework of the settings of a rom
