Ok what i had to do was restore my phone and start it without the sim card and then freeze device management and them put the card back in...maybe TMobile is sending some type of lock? Anyone else?

Are you using SuperSU? I was having issues with that not granting root permissions correctly, so my root apps wouldn't do anything that requires root.. i.e mount r/w

I found out if you restore with cwm 5026 or 5027 this will happen...you have to use one of the touch recoveries...

Can't mount with root explorer?

I am trying to edit some stuff in the system, but root explorer won't mount, if i press the mount r/w nothing happens. I have also tried es explorer with the "mount file system" checked and i just get a "sorry, operation failed". I am rooted and have given them both su permission. I tried having su forget the apps and regive them permission, didn't help. Rebooted, fixed permissions and still a no go. Any one have any ideas? I am running stock rom and kernel.

Did you restore a nand backup with cwm 5026 or 5027?

Restored a nand backup of stock rom with 5026. Is that the problem?

Other people have been having this problem with nand restores too. The only solution I've seen is a wipe and fresh install.

CM10 Mounting /system a read/write

I'm trying to install an adblocking hosts file, but I can't mount system as read/write. I tried in CWM and terminal with SU permissions. Any way to fix this or it just doesn't work (new to CM10 )
Thanks

Have you tried Rom toolbox and root explorer?
Sent from my SGH-T989 using xda premium
Yep, I've used ROM Toolbox and a root file manager, but all of them fail to mount

boot into recovery and do it from there or your can try Chainfire's insecure kernel apk

Root question

Is it possible to root the device, make what modifications you need to then remove root as there a few apps I have that won't work if I'm rooted yet I'd like to make a few mods but that would require rooting.

No, because every time you start a root app it will ask for root permission. What are the apps that won't work while rooted? I haven't ran into any yet my self.

A Root App ask only first start for root permissions.
A Root App won´t work with all functions without root permission
I suppose it's possible to make modifications to the system with root and maintaining hem after removing root, but that would have to be a one time modification.

It would not be possible for you to access any root app and access them after unroot as it will request permissions from Super Su and more over if you try and access it would either crash or give you an error saying you donjt have root access.
For example I want to modify the standard keyboard so the symbols show on the keys but you need to root to do this yet if I root, Sky Go won't work so I'm wondering if I could root, modify the keyboard then unroot so Sky Go still works but the keyboards mod still works

4.3 Root apps don't work

Tried both cm10.3 and liquid smooth, and apps like titanium backup and scary won't work. TBP just stalls when trying to restore and adaway just stops at parsing.

Did you enable root in developer option
Download Super SU from Play Store and update Superuser binary via CWM.
Sent from my LG-LS970 using xda app-developers app
Been covered completely but..... You need to update you su binary and change your back up location from sdcard0 to legacy doing that titanium will work again for you

For back up location go into titanium's preferences and then back up folder location click it then detect whole device then change it to legacy agreeing to move them to there, I never had to do the su update all I've had to do was storage but several have had to update their su ... so I'd your needing to then download su from market, goo into us settings and chose to update binary but do it through recovery... Hope that helps ya Bud

Note 2 after 4.3 won't let me root.

I updated my galaxy note 2 till 4.3 but i want to put a mod on it or a rom to give me the note 3 features on it and I don't have a pc to do it so was gonna do it via my phone my superuser keeps saying if you just upgraded to 4.3 and superuser can't install it this is an error is there away round this? It wont let me root at all.Many thanks.
Just asthe warmingsays. You need to re-root your device using a computer bud
Sent from my GT-N7100 using Tapatalk
Dude, just installing supersu app from playstore wont give you root access. You have to install su binaries in your 'system' partition. You will definitely require a pc for that..
By the way supersu is just an app to manage root permissions, it wont give u root

framaroot is not supported on 4.3 !!!
Thanks is there any rooting app that supports 4.3? My computer is broken so no other way of doing it 8-(

Just flash super su with your prefered recovery (like cwm or twrp). Download the zip from here: http://download.chainfire.eu/370/SuperSU/UPDATE-SuperSU-v1.80.zip flash it and you'll gain root.
