Rooted but no rw access to system. - Xperia Z2 Tablet Q&A, Help & Troubleshooting

Am trying to get my sgp512 so that titanium backup will work. My initial symptom was that TB would not recognize the free space on the SD card. I have found that I need to run a kitkat SD card fixer to fix this.
When I go to run it, it fails. I read the supersu logs and it says (system) mount failed.
I go to root explorer and try to mount system as r/w and it fails as well. According to the supersu logs the mounting permission is denied.
I run rootchecker and it says I have root.
Any thoughts on how I can fix this?

[Q] How do I backup my /data?

Just as the title asks, what way can i backup my /data folder on my phone?
This app can do:
http://download547.mediafire.com/q29mmmao8urg/1mnp840xlv9v6qq/App2Card_2.9.6_26June11.apk
Ive been using it for long time instead of Titanium backup to backup not only files, folders but also apps with settings. All you need is Data Tools/Backup/files, folders, just select the desired item
Hope that help

Thank you, I will try it out!
Im getting a "Failed to Backup" error when trying to backup, anyone else having this problem when trying to backup the file /data on the root of my phone. I have root access and when i launch the app, su is allowing it root access. I might try uninstall, reinstall, reboot.
Edit: Simple Mistake and fix, needed a larger SD card. Thanks flusshd!

I dont think so, but I think your sd card is not enough of space for this big /data, its more than 2GB. Did you check for this?

No. Not possible to use Root Explorer to remove files without root.
Try clearing aplication data first else use adb while in recovery to remove it.

URGENT! HTC One no os installed!

I did a full wipe of my phone to see If I ccan get rid of cyanogen mod. Now I have no sdcard folder. and I'm stuck in the TWRP menu. Is their anyway of getting my phone back? I have AT&T. I have no android software nothing. but in filemanager It finds a couple folder mostly all empty. Did I void my warranty? Will I never get my phone back?
ANY HELP WILL BE GOOD.
Do you have access to a file manager from twrp? Is your sd card partition mounted? You might be able to flash another rom from twrp or try using adb commands

[Q] Files disappeared after upgrading to Omega v51

Hey there. I've just been updated my omega rom from 4.1.2 (can't remember the rom version) to Omega V51, after backing up via clockworkmod.
Now the rom is working perfectly, except the fact that my data disappeared. The storage is almost full in my phone (can't update/download apps), but it seem to be empty using file explorer,
When trying to restore through recovery mod, I can choose the file I created, but of course it won't let me (md5 missmatch).
How can I restore my data??
Thanks in advance.
Look in Device\data\media..... there u will find the content of your sdcard.
just move everything to drive 0 exept 0 , obb and legacy.
There is something written about why and how they changed our internal sd. use search. Ive asked the same question couple of days ago.
Hope this helps.
Danny
Sadly the 'data' file is empty
Are u sure you looked in the data folder on your device? Not the data folder on your internal memory (sd)

I'm sure in 100%. By the way, when selecting all the files and folders in the device (via es explorer) it show about 3.15 GB, but in the phone settings it says just 387 available storage...
In ES explorer turn on root explorer... else you will see an empty data folder on your device.
This folder cant possebly be empty cause this is where android stores your app data and so on
Sent from my GT-I9300 using xda app-developers app
Still empty....
Well my friend... yhen you have a very special problem if in fact your data folder is empty.... :0
Ofcourse you did load system as r/w when you selected root explorer?
Sent from my GT-I9300 using xda app-developers app
Sure...
I'm reflashing the rom now... and when getting in to the recovery "choose zip from sdcard" I can see all my missing files..
I know... that is exactly the problem i am talking about....
In android you see that your internal sd got renamed to drive 0 and your files are missing
But when you enter a "old" recovery you will see your old internal sd and your missing files
Your old internal memory got placed in device/data/media.
Which you can only see when you load your system as r/w.

Forgot to mension...you must be rooted! Have you got root? Sometimes when going to android 4.3 you loose root... check your super user app.
Sent from my GT-I9300 using xda app-developers app
Can you please explain me how to do it? Clearly I'm not doing it well...
Anyone...?
Ok..
Go to your app drawr...tap SU app and check if you got root.
If you dont get any error message i guess you got root.
Then,
Go to esfile explorer. Assuming you have got the latest version go to settings-tools-rootexplorer.
If it says on then tap on rootexplorer TEXT not the on/off button.
A menu pops up.
Select: load r/w (something like this mine is in dutch)
Choose r/w
Confirm ok
Browse to device/data/media. You do this by tapping the / button in top left corner.
You should be able to see files in data by now...
Then in the media folder select all the files exept 0 , obb and legacy and place them in internal memory 0

Very strange... I just can't work it out, SU isn't installing on my phone...
You could try to flash a previous version of omega.
Then root your phone
Then flash the super user update thats in the link i posted
Then flash omega newest version.
It appears that version broke and keeps breaking your root.
Have you searched omega forum?
Sent from my GT-I9300 using xda app-developers app
Well?
Maybe you could also try a kernel with auto root function?
Googy max?

Ideafriend.apk is the app who manage your mesages. It allso manages your dialer and contacts. Do a backup with titaniumbackup and try to remove with some root uninstaller tool. Allways Make Backup. And one more thing... Try to install one custom recovery like TWRP or CWM.

Hi. Did you set the permitions read write to your su binary and supersu apk?
Set like that with root explorer:
SuperSU
To Read colomn
Mark owner
Mark group
Mark others
To Write colomn
Mark Write
Su Binary
To Read colomn mark all
To Write colomn mark owner
To Execute mark all
Then mark Set UID and Set GID
After that restart your phone.
