Can't get any backups to work

Hello,
I having been having some major problems the last 2 weeks with any and all backups i create of my phone. I have tried to make backups of various Roms using both Rom Manager and also directly by flashing into recovery (CWM touch). Each time the backup is successfully made, but then when i try to flash the backup i get errors saying "file not found". I lost my stock rooted backup, a backup of CM10, a backup of Liquid Smooth, and a backup of JellyBam. Does anyone have any idea why my backups don't seem to work? This is incredibly frustrating as I lose all of data and have no security blanket should something go wrong. Every time i flash a new Rom i wipe Dalvik, Cache, and factory reset/wipe.
Anyone have any idea what's going on with the backups?

what versions of android have you been flashing and are you sure your on the latest recovery?

Thanks for the reply. believe liquid smooth was version 4.2 and the jellbam was 4.1.2. My stock was either 4.1.1 or 4.1.2, whichever the last update went to. As far as CWM, I am on 6.0.2.3.

Not sure if this is relevant in all this, but my Titanium Backup wasn't working on it's own either when I flashed any new Rom. It would not see any backups and I would have to go into the Preferences and scan for the folder that had backups in it as it did not automatically detect backups in whatever folder it defaults to. This is also a recent development.

I started several threads on this very issue....my backups also are not working - "file not found" You aren't alone, once more people start experiencing this I'm sure we will see an answer

I've tried searching and nothing relevant came up. Do you also have several folders that appear the same when you reboot into recovery? For example, I have a folder titled "0" that popped up around when the issue started. I have a CWM folder as a subfolder under "0" that appears to be identical to the CWM folder that is not in a subfolder. That's why i brought up the issue i am having with titanium backup, wondering if that has anything to do with anything.
I've tried flashing the backups from both the subfolder and the non-subfolder, and nothing seems to work. The only thing i can successfully do is do a complete wipe and reset and flash a new Rom from scratch off the zip.

If your flashing anything 4.2 related its highly recommended that you use twrp as your recovery because of how the files get condensed into that "0" folder.. Your probably going to have to hunt down your backups I'm sure they are somewhere in that 0 folder

I thought it might have to do with the folder issue, but i have tried flashing from the CWM, backup, and various other folders in both the "0" subfolder and the main folder. In both cases i get an error that say's file not found. That said, do you really think twrp would make a difference? I'm pretty new to android, so i'm not really familiar with it beyond knowing it's a recovery like cwm. I'd be willing to try it out if it wont jack up the little amount of cwm i do actually know and am familiar with. At least now i can flash a new Rom and start over with a titanium backup of files if shizz hits the fan.

The only thing I can think of is to copy and paste the clockworkmod folder from the 0 folder to the root folder and try the restore process from the root folder instead of the 0 sub folder. If that doesn't work I dunno bro

I'll give it a shot even though I've tried loading from the folder directly already.
How would i move it? I've actually tried using file manager and it doesnt let me. It says it can't move the file, or any file actually, from the "0" subfolder.

so i made some serious progress. I used ES file explorer instead of file explorer and it let me move the file for CWM from the "0" subfolder to the main folder. It said that it was going to overwrite everything in the main folder with the subfolder stuff. I accepted and then i dirty flashed a backup of the same Rom (in case the file would not be found again) that had previously not worked.
It actually ended up working. I am afraid to try to flash a backup after completely wiping b/c i dont want to go through the crap of setting everything up again tonight, but i will give it a go tomorrow and report back. So for some reason, backups can't be flashed from CWM from the "0" subfolder, and they can't be flashed from the main folder, unless you move the files from the "0" subfolder to the main folder.
Hope that makes sense to anyone that may have this problem.

If you have the time and are by a computer you can also just move everything out of the 0 folder into the root folder and just get rid of the 0 folder altogether and start from scratch. I think it has something to do with cwm and how they recognize the file system. Like I said you should give twrp a try its very good.

[Q] Thought I bricked but now dupicate files

I had resigned myself that I had hard bricked going from CM Nightlies to a different ROM but was finally able to get it in download mode....I think taking the battery out was the key. With it in, would get the words "Samsung" for about 2 seconds before turning off. In download mode I return it to stock and go through the process of rooting using MrRobinsons way and than install a few programs including Titanium Backup, CW recovery, GooIM and Superuser and lastly root explorer. The phone seems to be working fine.
I should say that as I was flashing from CM Nightly to the new rom I could no longer see my SD card. I thought it was a bug with CM. But now I realize that my Titanium backups never went to the SD Card but to Box and to the internal main memory part of the phone. So even though I thought I did a clean install through Odin it now shows the normal folders of Android but also another folder called " 0 " right above the folder called alarms. Inside that " o " folder is an exact duplicate of all of the normal android folders including my Titanium Back-up which has my backed up programs??
For lack of a better description its a duplicate phone inside this " 0 " folder. I really don't know what to do and am a little afraid because I came so close to bricking it...or at least I thought.
I only have 3 GB of memory left on this "Clean Install" of internal memory with nothing really on it.
I guess I need to know why it didn't format everything through Odin and how I correct it.....but the phone works like stock as of now.
I do as I said also have Titanium Back-up on Box but thats another issue.
Hope that made sense, thanks in advance.

Use root explorer
Navigate to data/media/0
Select all
Move everything in there too data/media
When it asks, choose merge
After everything is moved, verify there is nothing in the 0 folder, then delete it.
Reboot
Your internal sd should be back to normal. As for how much space will be available, that depends on how much stuff you have on there.
Why did it happen? Android 4.2 has multi user support. The 0 folder is user 1. When you go back to a 4.1 Rom, it doesn't move everything back to a single user profile. There is a flashable zip on the cm thread for going back that fixes that for you.

Thank you

[Q] Internal Memory Full

I have recently rooted, installed CWM & CM10.1 -- The problem I have is now my internal SD is close to being full, but I havent installed anything on it yet besides a couple apps and some pictures.. Total Internal memory was 16GB.
When I go to Setting > Storage - its shows I have 12.5 GB of total space, but only about 1 GB available.. It shows apps and other things on the phone such as - APS 293MB, Pictures 550MB etc.. But added up it only amounts to maybe 3GB.. So I seem to be missing 13GB of space..
What I think may have happened (and I dont know how to fix) is.... Is it possible that I did the back up of my stock rom & titanium back ups etc.. all onto my internal SD card ? I didnt back anything up to an external drive or my PC, becasue the instructions I followed did tell to do that, nor how to do that.
So if that is the case I would like to extract those file from the SD card on my phone to creat some more room ?
Thanks.

Even if you did backup everything to the internal sd, a cwm backup is usually about a gig and I have 100 and change titanium backups and it also takes up about w gig so I don't think that is the problem. You should be able to hook it up to your PC and check the folder sizes on your SD card. You can also move the clockwork mod folder and TB folders to your external sd but you will need to set up the new location in TB's preference s option. If all else fails backup everything and copy all pics vids downloads and everything else you want to your PC or external SD, and wipe everything from your phones settings menu. This will wipe all data and game data too so be careful to get everything off it you want. Oh yea, make sure you have sync'd or backup up your contacts. That's a pain in the ass.

I had a problem like that when I first got my s3 last year and for me it was 2 files in the lost folder that were like 5 gigs each
hmmm......

Would it have anything to do with when after I rooted and was installing CWM and the new ROM.. It said for me to back up and save my old original ROM/configuration.. Which I did select back up.. But I didnt save it to my PC, I believe it just saved to my phone somewhere.. If I may need that someday I should likely save it correct ? Can someone give me an idea how to access those files so I can transfer off my phone ?
Maybe that is the problem ?

I don't recall ever seeing that option but it was awhile ago. You could try grabbing a root explorer and look around for a large folder. Es file manager for example. I kept my stock backup for awhile but never needed it. You can always find a stock image to reflash with Odin but I'm paranoid and keep at least one cwm backup in case. You could reflash the ROM you put on when you rooted and choose not to select backup this time. It will clear the phone so as above be sure to transfer or save anything you want. Get a little bit used to the process of backing up apps and reinstalling them when you switch roms cause these devs are awesome and always have new features to try. It goes pretty quick after you do it a thousand times. What ROM are you currently using?
---------- Post added at 08:11 PM ---------- Previous post was at 08:02 PM ----------
There is a free app called storage analyser in the play store. I didn't try it but it looks like it will break down what is stored and where. Could help in this situation. Your internal SD should pop up on the computer so if the problem is in there you shouldn't need a root explorer to find that. If its not in there maybe to a cwm backup to external sd and flash something new.

I have only flashed once.. Using a tutorial from XDA, I rooted using ODIN, I installed CWM v6.0.3.0. followed by flahsing CM10.1 Rom. (10.1 -20130414-nightly-d2att)
During the tutorial it said I should back up my existing stock ROM incase I ever want to go back, so from CWM I seleced back up/restore then selected back up. It didnt tell me how to find this file and save to my PC or somewhere safe.. so is it possible that there are a bunch of files still on my S3 that I cannot see from just plugging it into my pc ?
I would really like to do this properly and remove everything from my S3 and just start with a fresh ROM again.. and know that what I need to have backed up was done properly onto my PC or somewhere other than my phones SD card. pls help = )
I just remembered a problem I ran into while performing the above steps.. I dont know exactly what happened but I think the version of CWM may have been old.. so I tried to update or install a newer version (followed another tutorial) is there a change there is the old version still on SD card ?

Do you have a micro sd card? This would allow you to completely wipe the device and install your OS

Yes I do have one I can install. (2GB) would you be able give me a list of the steps on how to do this properly ? (or link to a post that does)
Also, I do find I ejoy the CM10.1, is the verion I have one that I should be running or is there a standard version ?

If you enjoy cm10, stick with it. I'm on tasks 4/23 release and its running beautifully
Place the rom and gapps on the sd card, get what you want off the phone and you should be all set.
Check out the link in my signature for more information on flashing. when you format /system, also format /data + media.
Before you begin, go in rom manager and update your cwm recovery. Latest is 6.0.3.1. Or download the one at the bottom of post #2 in my signature link and flash it in cwm (then advanced > reboot recovery to have it take effect before flashing the rom).
Keep me posted

Ok, I got CWM updated to 6.0.3.1, I backed up apps with TB and saved file to ext SD and got all my pics/vids transferred as well.. Now I just have a couple questions.
1) When I originally backed up my stock ROM in CWM it would have saved to my phones internal SD correct ? Because I could never find it. I just did a back up again and I plug phone into PC and cant find that one either ? Where would the be going ?
2) Can you link me to a good version of CM10.1 for my model as well as the proper google apps.. I cannot locate.
Thanks.

If you backed up to your internal sd card then the location should be something like storage/titaniumBackup. Inside that folder would be an oddly dated folder with all the contents. Transfer that to your computer as well.
Cm10 and the respective gapps are in the original android development section. You can also find their stable and nightly releases on their website. Be sure to only use the ROMs for your device model

Ok I just installed new ROM and now its worse, now I have less internal room.
Here are the steps I have followed.. (obviously its not wiping my entire internal SD right ?)
- Wipe Data / Factory Reset
- Wipe Cache Partition
- Advanced --> Wipe Dalvik Cache
- Mounts / Storage - Format System
- Install Zip from SD --> CM10 file.
Once phone boots up, I go to Settings --> Storage - Here it says I have only 2.6GB of space available and I have absolutely nothing on my phone yet, fresh install.
Am I missing a step ?
Thanks.

You didn't format /data + media like I said.

Phantom internal storage problem (Stable CM10.1.0 on AT&T I747)

Hi, I just installed CM10.1.0 on my GS3 using CWM recovery from the device after rooting. I'm thinking this may be part of the problem, since it didn't seem like it entirely formatted the internal SD, but I'm not entirely certain. View the first attachment to see what I'm talking about (btw, Misc. got cut off but says 7.07MB).
As you can see, my total space is 12.05GB and it's saying that only 2.38GB is available, though the status bar and storage categories don't support that information (adversely, only about 2 gigs should be used). When connected to my laptop, it says that all this space is being used (view second attachment).
Am I correct about the way I installed it being a problem? Or, is there really phantom storage on my device? It seems that the phantom storage would be coming from the \data folder, but I'm unable to find any problems via SD Maid.
If it's a problem with the way I installed it, I was unable to get Heimdall running properly (on my Windows 7 laptop) with the instructions provided by Cyanogenmod or several threads on XDA, so if anybody could help me get it installed properly I'd be grateful!
Edit: I also flashed Gapps from ROM Manager w/ CWM Recovery after I finished CM10.1.0 installation. Could this be part of the problem?

i'm assuming you came from stock firmware. make sure you have everything backup up and follow the wipe procedures outlined in this thread: http://forum.xda-developers.com/showthread.php?t=2179330 before flashing the ROM and gapps again. cheers

Ok, so you're suggesting to flash from recovery so everything is wiped properly and CM10.1.0/Gapps will be installed at the same time? The first time I tried this, I thought I had put the CM zip file in but couldn't locate it, so I flashed stock/rooted and did it through ROM manager. If you really think that will help, I'll give it a try.

I don't think the wipe recovery actually wipes user's data. Just the applications and settings.
I've noticed that when I wiped my GS3 after I initially installed CM10.1 and even yesterday when I installed LiquidSmooth and did a wipe afterwards it created a folder called 0 and moved everything in there instead.
When I had the phone connected to the computer. Folder 0 properties would show there is nothing inside. but when I browse into it. I can see that my wallpapers, ringtones, music files were still there. So I cut and pasted it to the main \sdcard folder and deleted the folder 0.
Perhaps the same thing has happened to you? Use a file browser on your phone or connect it to the computer and see if you see the 0 folder. if you do your previous data files might be the reason why your phone reports low storage available.

1. when you're changing android versions, for example from 4.1.1 to 4.2, it is always recommended to do a full wipe before flashing.
2. when you're changing from one 4.2 ROM to another 4.2 ROM, you will also often see this multiple 0 folder issue when not fully wiping.
3. never flash a rom from anything other than a custom recovery - TWRP or CWM
please understand what you're doing before you continue.

xBeerdroiDx is right that I was flashing from a stock rom and I'm definitely not having the same problem as you, but if I were you, I'd use the link he posted above to make sure you were fully wiping before installing CM and Gapps. Looks like I'm going to have to do the same thing to fix my own problem though.

I followed your instructions and it didn't work... still shows 2.75GB available after reboot. Any other ideas?

For anyone who may be experiencing this problem, I fixed it by following xBeerdroiDx's instructions and then by formatting sdcard. Be sure to put the rom and Gapps on an external sd and remove from the device before booting into recovery. After all that's stuff wiped, you may put the external sd back in and load the zip files from the external sd.

[Q] Phone's internal memory system messed up after installing ROM

Hi,
I flashed last night Temasek's CM11 4.4.2 ROM (http://forum.xda-developers.com/showthread.php?t=2596887), wiping user data, caches, etc (I was on a rooted stock 4.1.2 ROM).
Everything is working great so far, I love this ROM, I just noticed a problem that it's quite annoying: it seems that the internal user data file system (which would be the /sdcard folder in my old ROM) is all messed up and replicated. Here;s what happens:
I created a backup of the current ROM with Online Nandroid backup. If I use a file explorer from my phone (X-plore) and go to the "partition" /storage/emulated/0 I can see the backup created in /storage/emulated/0/clockworkmod/backup/.
However, if I connect the phone to my PC and browse the contents, the partition that I see isn't that same partition, it's an older one with older files (for example it has a clockworkmod folder but the backup isn't there, and some folders are different). What;s worse is that I can't find this "old" partition when browsing my phone with X-plore. These are the palces where I've looked at:
- /storage/emulated/0 (shows the partition where the backup I just created went, I can see the backup there)
- With root privileges:
- /data/media (shows an older second partition with different folders)
- /data/media/0 (shows the "right" partition, where the backup is)
- /sdcard (again, shows the "right" partition)
- /storage/sdcard0 (same here, shows the "right" one)
So to sum up, it looks like I see at least 3 diffent partitions:
1. From my PC, I see an older one that I can't see from X-plore (I tried Cyanogenmod file explorer too)
2. From my phone, I see the one that has the backup I just created
3. From my phone too, I see a second old partition (different from the one I see from my PC)
So what I would like to know is:
1. How can I transfer the backup to my PC if I can't see the partition that holds it from there?
2. Is it safe to just delete all those folders in both old partitions? I'm sure they're taking space unnecessarily
Any help would be much appreciated!

After flashing any CM/AOSP Rom. They actually create a different folder set up. That's because of the ability of different users...
You need to apply the restore SD card after downgrade.

Hey! So it seems that did it!!! Now I can see ALL the contents in the /sdcard partition (X-plore shows it as /storage/emulated/0)
So my question is (I'm still pretty noob at all this): all the files/folders shown there shouldn't be critical for the OS to work, right? They should all be stuff saved by apps, that if they get deleted the worst thing that will happen is that those apps will lose that info, right? I ask because I can recognize most of them, but not all of them, so I'm not sure, and I would like to remove as much stuff as possible.
One file that makes me doubt specially is /sdcard/clockworkmod/download/download2.clokworkmod.com/recoveries/recovery-clockwork-touch-6.0.4.3-t0lteatt.img. Is that the actual CWM recovery that I have in my phone? Or just the installation image that can be removed?
Thank you very much for your help!

I ended up deleting everything from the sdcard partition and restoring the stuff that mattered to me, and everything seems fine now. The only weird thing is that when I create a backup with Online Nandroid backup (which gets stored in /sdcard/clockworkmod/backups), I can't see it when connecting my phone to my PC. I can see everything else in the sdcard except the backup. I've tried unplugging and plugin again the phone, rebooting it, rebooting my PC... but nothing. However, if I zip the backup folder with X-plore, leaving the zip file in the same folder as the backup folder, my PC can see it...
Weird thing but oh well!
