Hello,

I have SM-N9005 variant and recently I updated to the latest android 4.4.2 leaked version with Odin, and then rooted with CF-Auto-Root.

After that, I lost the permission to write to external sdcard.

I searched and found this: http://forum.xda-developers.com/show...php?p=49603814

I backed up /system/etc/permissions/platform.xml and then I followed the instructions there.

After restart, a lot of app stopping messages showed and I had no access to file system or network anymore.

I used adb shell to restore the original platform.xml but it didn't helped in any way.

It seems that all mounts and networks are working, but none of the applications has permission to use any of them.

How do I resolve this, without wiping all my data?

Thank you!

You need to set the correct permissions on the .xml after you overwrite it back into the /system Off the top of my head I can't think what they are (just out of bed and got to work so still sleepy!)

I tried 644 and 777 but the problem persists.

rw-r-r which is 644 - read wrong

or chmod 666 -- forgive my lack of memory, it has been a long time since I have used chmod commands, few years since my glFTPD / site modding days.

i dont know if it helps in your situation but did you try the "fix permissions" from a custom recovery like twrp?
there are also scripts you can execute in a terminal, the knoxout script linked in my sig for example has a permission fixer included.

Thank you.

When i run this, no matter what are the parameters, for example: sh kn0x0ut.sh kn0x0ut

it says:

ERROR: Unknown parameter ""
Removing all temp folder /data/media/kn0x0ut_temp...

just type sh kn0x0ut.sh to get all commands.
if you dont get this working, you can do it from twrp (i think cwm too)if you have it.
tap on "advanced" and then on "fix permissions".
