[Q] data folder reverts with restart or remount. No permanent uninstalls.

I was using XXKPQ Gingerbread. Soon my phone started restarting and giving errors.
When I use ODIN I can put new files in to system folders. I installed XXKPE and clockworkmod, then I used adb remount, adb shell to delete everything under data/data, data/app, sdcard, sd-ext. When I do ls it said folders were empty but after restart everything came back!
Is there a way to mount a file system as a volatile memory? It accepts all the changes I say but it reverts back when unmounted and remounted. I thought it might be permission problem but fix_permissions script does not solve it. Also I heard 0 available memory bugs in the forums but my case is not that either.
On recovery menu, I used clockworkmod options to mount the data folder, I erased everything in it via adb shell, and without restarting I unmounted and mounted again using CWM, the files were there again in adb shell!
Since there are files under data/data and data/app folders, I get crashes of those applications all the time when I try to use the phone. If I install the same application from market it works fine but after restart it reverts back to crashing.

Exists even after xxkpe + pit flash?
Try converting to ext4 and formatting and then flash xxkpe + pit.
Having read many such issues now, it seems its MoBo issue. Search around a bit. From what i have read, probably service center's the only one who would be able to help you now.

Try VurrutRom , when you install it the rom exchange the internal sd with the external sd.
you will see that your /data folder is now in the external sd. I hope this fix your problem.

@ggclanlord: This phone had motherboard issues before but this looks more like a protection to me. No matter which rom I install the applications and their settings just stay there. I might try ext4 later as well.

How do I change the internal sd with external sd? I have found this but it does not say it needs to be Vurrut. Is it somehow easier with Vurrut?

First of all, why are you trying to clear any partition manually ?
Second, /data is a separate partition altogether neither on internal sd nor external.
Flash a full xxkpe with pit and re-partitioned checked. Then flash CF-root. Your phone should return to normal.
Generally you should not need to manually format partition ever but in case you need there are options under Advanced in CWM.
Hope it helps!
Good luck !

Can you gain access into a device's internal sd card even though you have a bootloop?

I got into bootloop after installing some apps and I am just wondering if I can access my nandroid backup folder on my PC....coz apparently I need to change the folder name in order to get rid of "MD5 mismatch" during restoration in clockwork mod recovery.
Thanks in advance.

By default, the backup folder is on the sd card. If your device has a removable card, you can just put it into your pc & access it. You can also access it through USB by using adb commands, but you must have previously turned on debugging mode in the settings.
It's also handy to have AROMA Filemanager on your sd card. You flash it in recovery like any other zip (it doesn't make any changes, just launches the file manager). It also comes with a terminal emulator. It's quite powerful, and extremely handy when you can't get your system to boot up.

[Q] problem copying via adb

I was attempting to copy cnexus' Stock rooted rom for my gs3, but adb failed and said the file permissions were read only; when I check the permission status with root explorer it shows the permissions as rwx across the board. Does anyone have a suggestion to remedy this? My only other option would be to copy them to the external sd, then copy to \sdcard using root browser. Unfortunately there is no way for me to mount the phone in mass storage mode and just use windows explorer, and Kies doesn't connect to the phone(not my favorite program anyway) Thanks in advance

[ROOT] Move obb folder to external SD (mount -o bind folder)

Using on CM11, should work for any android build above 4.#.#
If you are having trouble mounting folders like I did like SuperMount, FolderMount didn't work for me
Even if they work, they require payment for most important features
Get BusyBox (Most custom ROMs already have it, like CM)
I used busybox mount because regular mount didn't work
Get the SManager app
Move the contents of obb folder to somewhere in external SD, (Or you can move the entire obb folder and create an empty obb folder in sdcard/Android)
Create new script from SManager (or any other text editor and save it with .sh extension) and type the mount command in it
Lets say I moved the folders inside obb to storage/sdcard1/obbfolders, then command is:
busybox mount -o bind /storage/sdcard1/obbfolders/ storage/sdcard0/Android/obb
Save the file (in SManager you press back after typing and it asks if you want to save)
Click on the file you created and check the Su and Boot boxes and Save
Script should be good to go, click Run
I use FX File Explorer to verify it (obbfolders should be shown on the main page)
Reason I created this thread, I searched this for a quite good amount of time and couldn't find anything
All "mount folder android", "mount bind android" searches either come up dead or show me an app that doesn't work for me

Trying to follow your guide....can't get it to work ?
1: Moved the entire OBB folder to my SD
2: Installed busybox, started it, software says it is installed, there's a button to install again....don't know what else it does ? If I click install, well, it installs again
3: Created the new script, saved it, ran it. It seems OK
4: When I open FX File explorer, I don't know what I'm looking for, I don't see anything going on, no operations running ?
...I didn't want to delete the original OBB directory since I don't have confirmation of this working ?
Thanks for your help

almost there...
Hi there
Had the same problem and found your thread after quite some surfing. Following your instructions, all seemed to work fine, just had to inject an "su" before the busybox mount command, then the whole external_sd (/storage/sdcard1/) was mounted to an existing (empty) folder on the internal sd (/storage/emulated/legacy/External_SD)... at least that's how it looks in SManager. When checking the target folder via file explorer, it still looks empty.
My setup:
- Samsung S4 mini on Cyanogenmod 10.2
- phone is not fully rooted, but root is granted to SManager and Busybox
- external sd card has permissions "d---rwxr-x" and is owned by "system" whereas the internal storage has permissions "drwxrwxr-x" and is owned by "root"
do I face a permission issue?
If yes, how to solve that (tried to change permissions of the External_SD folder recursively using chmod -R under root... but didn't suceed)
If not, any ideas...???
Thanks for any hint!
cheers

I'm using Lucky Patcher to bind oob folder, you should try.

@needo2: Is it required to mount the folder? This could cause problems on rejecting sd card. Maybe it does work replaceing the source directory with a simple link ("ln -s") to sd?

[Q] Platform.xml - Samsung Galaxy Trend GT-S7580

Hi,
Apologies if in wrong section, but I have a query about updating the platform.xml file on my Samsung Galaxy Trend GT-S7580
to allow rw access to the external sd card.
I have rooted the phone and mounted the file system, via Mount /system (rw/ro) app. (check root and Titanium backup confirm it as rooted)
I can navigate to and update/save the platform.xml file, however whenever I restart the phone the file reverts to its original and my changed are lost.
Before restarting I was able to create a new folder etc on the sxt sd card, but again after restarting the folder seemed to be gone too!
Is there anything I am doing wrong, or additional steps I am missing out on?
Any help is much appreciated

Update .... turns out its the microSD card that is the problem. Cant seen to write or delete from it even though its not read only.
Got a new card and hey presto, worked fine
