How to fix /mnt/local shows empty? - General Questions and Answers

Hello, i have a problem with the internal storage of my android tablet, basically i installed a custom rom a while back but the wifi didn't work on it so i decided to go back in CWM and wipe data, cache + dalvik cache and /system, after that i restored my backup and everything went good (app installs fine from playstore and they work) but i can't see my internal storage on the integrated file manager or even from my pc, it just shows my sd card, the folder where the internal storage was is /mnt/local and now when i go there even with adb it shows empy, so with adb i went to /data/media and i tried this command i found on the internet :
mount -o bind /mnt/local /data/media
but it didn't work i still don't see anything in my /mnt/local dir
(and now after using that i don't see anything in my /data/media either)
my device is running Android 4.0.3 ICS and it is rooted, i also tried to restoring my backup again but i still have the same issue :/, before installing the rom i also created an image zip from the recovery just for safety but now im stuck as the only thing i found on the internet was one video of one person that just factory reset his phone and it worked again for him but for me it didn't, here is the video i saw, which has the same problem as me:
Thanks for the help.

Ok i fixed my /data/media directory by using umount /mnt/local, now if i do ls in /data/media via ADB all files show again but still no internal memory on file manager.

yes i did, i tried zarchiver but it shows empty, and when i connect the tablet to pc it only shows one drive named "Sd Card" when before it showed "Sd Card" and "Internal Storage" folder, i think that by restoring the stock rom the mnt/local got unmounted

[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?
http://forum.xda-developers.com/showthread.php?t=1088474
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 !

HELP No internal SD found

I have been having reboots lately and now I cannot access my internal SD nor is it found when I plug the device into the computer. ADB reboot recovery just reboots the device. No SD card found when trying to view storage settings, gallery, or ROM manager. Not sure how to fix this and looking for some guidance. Thanks.
It looks like you can boot in to android, use a file manager that can go up to root and see if theres anything in /data/media/. If there is then your internal SD data should still be there.
Did you happen to try a new rom or something before this occured? I recently had a rom remap my mount from /sdcard/ to /storage/sdcard0/, see if anything's there.
If it is the case that it was remounted, flashing superwipe LITE should be able to get the filesystem remapped properly. The LITE version will wipe everything except for /data/media, which is where your sdcard data is as that was the original mapping.
This is indeed the case. I have all my files in the data/media and I was remapped to storage/sdcard0. Where do I get super wipe LITE? I can't boot into my recovery so how do I flash something? Presumably I will need to use adb.

[Q] Nexus S can't see sdcard

Hi All,
I've just updated my Nexus S i9023 to the latest stable Cyanogen Mod (10.1.3) and am now having problems seeing the internal sdcard. I've tried flashing 10.2 RC1 as well as mounting it via recovery mode but everything I do fails to get it to mount.
Would any body have suggestions on how to troubleshoot this (best place to look for logs to find errors) or have come across this before and know how to resolve it?

when you turn off your nexus,then turn on holding volume up and power,can you enter into mode where you can access your sd card?
Can you see your files from sd then?

No, It doesn't see it in recovery either. If I go to Mounts and Storage section and do a "Mount /sdcard" it just give a "Error mounting /sdcard!" warning
Same if I try to format /sdcard. I just get
Code:
Formatting /sdcard....
Error mounting /sdcard!
Skipping format...
Done
A couple of other pieces of the puzzle
The phone was encrypted before upgrade (and since reencrypted)
When I go to settings -> storage, I see what looks like the contents of the storage flashing up before disappearing
HI there.
I used to have same problem all day and I found a solution which works for me.
Under flashboot I put older version of recovery-clockwork-5.0.2.0-crespo. Only with this one it allows me to see actually usb mount storage.
I still can't mount the storage card for flash, but I can see it in my laptop. So I do full format in fat32. (It takes about an hour).
After that everything was fine.
Hope this works for you too.

Thanks for suggestion. I try but still not seeing the sdcard storage and mount / format from recovery give same error as above

Where are CWM Backups?

Hello,
I just unlocked, installed CWM and rootet my Nexus 5. Then I made a CWM backup and wanted to transfer it to my PC. But in the storage mounted on my PC I see only the CWM folder but not backups inside. When I boot into CWM and want to delete backups I see all backups I made. I tried also to mount SDcard via CWM, but that doesn't work, nothing happens after hitting mount sd card.
Where can I find those backups? MaybeI have a problem to understand the device storage w/o a sd card :/ it's my first phone w/o SDcard
TIA

Use a file explorer, preferably ES File Manager. Then, press the globe on the upper left hand corner and swipe down to activate the root capabilities. Then, go to the root of your phone and it should be in this folder
/mnt/shell/emulated/clockworkmod/backup
They're in /data/media instead of /data/media/0 (which is what /sdcard points to) because CWM didn't change teh mount point when android did in android 4.2

[Q] CWM Backup failed -> internal storage full - can't find&delete the corrupt files

[Q] CWM Backup failed -> internal storage full - can't find&delete the corrupt files
Hey guys,
I have a big problem with my Tablet after a CWM Recovery failed: The internal storage is completely full and I am not able to find and delete the uncomplete backup-files.
That happens after t I tried to backup to the internal storage of my device. After a while the backup process failed (I think because of insufficent storage on the internal SD card for the backup file). Afterwards I used "backup-to-external-SD" and it works fine.
The problem is now, that after I started the tablet again it says "inssuficent storage on internal SD card" and I cant even install an 155kb app any more. => CWM didn't delete the files after the first backup process failed.
Usually I would be able to use my file explorer, choose the internal sd, look for the backup folder with the uncompleted files and delete it. But it doesn't work! The folders of my internal SD card don't contain the massive damaged files.
But when I go into Recovery and click on "Flash files from SD" I see the following folders:
- /0 -> contain all the sd card files
- /clockwordmod -> contains /backup/ with the damaged CWM files I want to delete but can't find with a file manager
- /legacy
- /obb
Click to expand...
Click to collapse
Does anyone know how I could be able to access the folder I can see in the Recovery so that I can delete the clockwordmod/backup/ folder?
I would really appreciate your help :highfive:
EDIT: I had a similar problem once and was able to solve it by formatting everything via CWM-Recovery, but I can't do it this time again because of a lot of important files and data.
EDIT2: I use CWM Recovery v6.0.2.7

You can find the file under data/media/0/clockworkmod/backup
You will need root access.

Thanks for your help!!
The backup folder you mentioned is empty, but I found the files here:
/data/media/clockwordmod/backup
So the filesystem the Recovery shows me is in /data/media.
Edit: Without root access I only saw an empty folder (info for people with the same problem)
