[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?

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.

what program did you use to flash the ROM? how many times have you flashed a ROM (specifically 4.2.2 ROM)?

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.

NOOB Q About Memory

Hi All,
Hopefully this should be a very quick question. I'm loading CM onto my phone, and this is the first ROM I've ever used. I've loaded CWM, made a backup, and I'm about ready to go and load CW on. I've noticed though that out of the 5 or so gig the phone comes with for internal memory, about 4gb is used up. Is this just the system and the back up and apps?? It seems quite a lot. Will CM fill this up further? Will I encounter any issues?
I hope thats all clear, but excuse me for being a beginner.
EDIT: This is now even more relevant now CM is flashed. I've just looked in the file viewer, and there's still all the folders etc from the old samsung, and amazonmp3 etc etc. I thought the "wipe data/factory reset" in CWM would have cleared all this.....
Many thanks for looking.

Factory reset only wipes the data partition. For the first time installing a custom ROM, and especially going from stock to cm for the first time, you should wipe the system partition which can be done from cwm.

Hi again.
So I finally got round to trying to get this sorted.... and I'm failing. I've booted into CWM, rerun the "wipe/data factory reset", rerun the "wipe cache" then went into "mounts and storage" and did a format of the system partition, but it still hasn't cleared any of the data.
Am I doing something incorrectly? I didn't want to play around with it too much, in case i bork it all. Any help would be massively appreciated.
Also, I'm a bit concerned about what formatting the system partition will do. Does it just clear the rom already on there, and I can then flash Cyanogenmod back on from my sd card?
Thanks

Formatting system partition wipes the currently installed rom / system apps.
How do you know that it is not wiping the data? If you do a system format and your rom still boots then it isn't working properly.
It could be a problem with the version of recovery (cwm / twrp) that you're using. It can't hurt to update it, which could be the case here.
Good luck. Let me know how it goes.

Thanks for coming back so quickly!
So if you see the attached, this is what I'm looking at. The phone has 5.5gb internal memory, of which, looking at the below, I'm using about 1.5gb, BUT I only have 1gb left to use, and I get warnings about lack of memory.... So there's 3gb being used for.... I don't know.
When I first put cyanogen on, I noticed that the file structure from stock was still there (i.e. all the folder my old apps made). I expected when I put CM on that it would wipe everything, including all of those folders.

You can try an app called es file explorer, it has a feature that fully scans the contents of the internal SD card.
It should show a list of all the folders from the old stock data folders. You can multi select and delete what you want.
Another option which is more efficient, is to make a full backup of all the internal data in your PC. Then fully format the internal SD card via cwm and transfer which contents you need back from the PC such as photos and music. Asides from photos, music and other media items, most of those internal SD contents aren't needed as Android uses these folders for app data etc.
Always make back ups.
Your welcome.

Yeah, I have got ES File explorer. I couldn't find a "scan" but I've gone through all the folder on my device and I can see the following:
/storage - 3.83gb
/mnt - 2.11gb
/sdcard - 893mb
A lot of this seems to be duplicated though.... The stuff on mnt seems to be a shortcut to whats in sdcard, and all that in storage seems to be in the other two. I don't technically think it's all duplicated, but different ways to get to the same stuff, which makes me very nervous about deleting any of it....

Just got a liitle program to give a break down. See attached.
Surely my system data shouldn't be that big?

I recommend you make a full back up in your PC and format the SD card and transfer the contents of your current SD folder back. I've done it before on different devices, I do it on first root / cm install coming from stock because of all the old obsolete data. Apps like clean master won't removing it because it's marked as important for stock users. It shouldn't be a problem.
Note:
Having different links to the data partition is normal. It's purpose is compatibility.

It's possible that's reserved for the system. Mine is similar. You can still use it if you convert user apps into system ones.

Just found this: http://forum.xda-developers.com/showthread.php?t=2083107
It's something to do with backups. I'm gonna read through that thread and see if I can find out what I can/can't delete without bricking the phone.
Massively appreciate your time and repsonses on this iKlutz. Just out of interest, did you do a backup when you installed a rom? Have you found that the backup is this big??

Use ES file explorer or other file manager with root explorer capabilities.
Go to /data/media
You should see:
0
clockworkmod
legacy
obb
In clockworkmod folder I've found a backup (2.0GB) that was made by mistake to internal sotrage, since I allways do backup in CWM Recovery to external SD.
Deleted and 2.0GB were gained.

Hmmm. Data/Media is empty.... I might delete the back up from CWM. If the worst happens, I can always flash from the external SD card can't i? Do I "need" that back up of the device when it was stock?

Do not delete.
Copy the folder(s) that you have in the "backup" to the external SD card to the "backup" folder in the "clockworkmod" folder.
Then, you can delete the backup folder located in "data/media/clockworkmod/".
I allways save the backup of the stock ROM's.
To restore in CWM recovery, simply choose "restore from external SD card". And to backup, choose "backup to external SD card", or it will backup to the internal memory.

No.... I don't really know what to do with it.
I've got an s3 mini with Cyanogen and CWM and the system data portion is only 54mb.
I might go into CWM and start deleting things. If I delete the backup I made of my stock phone when I first rooted and added CWM, I can't see too many issues.... I can always flash a stock ROM again can't I?

Yes, using Odin you can flash stock ROM again.

[Q] CWM Backup Question

Hi, I have rbox's custom recovery installed and a FAT32 32GB flash drive and wireless keyboard connected through a USB hub. Before I decided to upgrade to the newest pre-rooted ROM I thought I'd make a backup through CWM in case something went wrong. The custom recovery does not see my USB drive, but I figured I could back it up to internal and then move the backup file to the external through ES Files Explorer afterwards. From CWM I went to "Backup to SDCARD" and the app went through the process of creating a backup and then completed. I rebooted, loaded ES File Explorer, and looked for the backup... which I cannot find. The internal storage reflects the fact that the backup is somewhere on there, but I am unable to find it. I've searched for zip files through the internal (and external) device and cannot seem to locate it. I'm wondering where the default location for this is, or if there is some other way I can track it down? Thanks!

This is a good question. If USB storage should automatically be mounted when recovery starts, what directory do backups need to be in in order for CWM to see them and offer to restore them?

I think it looks in a clockworkmod directory in the root. But multiple people are reporting they aren't seeing the option for /dev/sda in backup/restore, so it's probably just broken. Unfortunately to get USB storage working I had to modify one of the core Android libraries and haven't tested it in a while. So it might just be broken.

My hope was that at the very least, that I could copy the backup from the USB drive to the internal memory before attempting a restore. Or, that I could use adb to push it to it. I realize both scenarios assume that thr device is at least still functioning in a state that one or the other options is possible. I'm just glad rbox spent the time to develop this and share it with the community.

TWRP Weird folder names and no .zip file

Hey,
I'm new in this kind of stuff but need help as fast as possible. So I tried to root the phone but let me tell you something else. When I enter TWRT (boot into) and try to install the .zip file it shows weird folder names that I can't see on the computer. I have Win10 if this matters and Android 8.0 or 8.0.1. The folders are:
acct
boot
cache
config
cust
data
license
mnt
and it goes like that. The problem is that about 85 or 90% of these folders aren't visible on my computer when I plug in my phone... The System is mounted in TWRP and everything is mounted. I tried wiping all the data. I have unlocked bootloader. Also when I go to some of these folders I see REALLY strange folder names like: 671hnsuh1b%nqjus Or something like. I've found out that it's encrypted but I just want to root the phone and find the .zip file. Also can someone explain me these acct, boot, license, vendor, version and other folders that aren't visible on my PC? Please help. I'm so confused, not clue what's going on...

You need to use the format data option to decrypt the internal storage. Better use SD card or USB OTG to flash the root file. Anyway don't wipe the oeminfo or vendor partition in any case and take a backup of all partition beforehand.

Well, I already used this option. The format data option and it's still the same. Maybe the version of my twrp helps: 3.1.1-1

Strange. What is the android version?Did you had any lock screen set before formatting? Can you please share a screenshot or log during formatting, if you have any. Anyway you can use adb sideload to flash the .zip file.Cheers

My android version is 8.0 so it's oreo. I've also noticed that the 3.1.1-1 version of twrp is the only one from what I tried that I can install the newer versions gave me an error. I had lock screen and it was code not a fingerprint but I wasn't prompt for a code after booting into twrp. Adb sideload seems to fail all the time so I can't do it :/.
The logs from wiping data are:
Updating partition details...
..done
Full SELinux support is present.
MTP Enabled
Starting ADB Sideload feature...
Starting ADB Sideload feature... (And it failed now wipe logs.):
Fomatting Data using mkfs.f2fs...
Done.
You may need to reboot recovery to be able to use /data again.
Updating partition details...
...done
So yea I'm so sad tbh with this... I'll try to install new twrp after the wipe if the wipe didn't help and will tell you if I get an error when I try to boot into NEW twrp.
EDIT: Ye still an error.
Maybe you have a link to the newest working twrp?

Nevermind got it. Downloaded the modded twrp by TEAM MT I guess from here: https://forum.xda-developers.com/honor-8-pro/development/wip-twrp-3-1-1-0-duk-t3625798 Works perfectly and SOLVED!

35 GB system partition on Oneplus 3 with omnidragon 8.1

My phone storage is filled with 36 gb of system storage like title says. I know solution is formating phone but i dont have access to a PC. So can anyone help me with this problem. I am currently using 8.1 custom rom

Install es explorer or something similar with a "storage-scanner" feature and you will find the folder where this extra space is being used, then take the decision of formatting the phone or deleting that folder.
Most likely it is leftover files from some previous app or something you manually transferred to "Android/Data" folder to hide them *wink*.
Let us know the result of storage-scan.

I fear that the issue is unrelated to an actual file taking the space, 36 GB is ungodly for /system, after all.
The issue usually crops up due to an incorrect encryption, or something in the neighbourhood of that. The common fix to it is by reformatting /data through fastboot then TWRP/recovery, but fastboot requires access to a computer, something that OP states they cannot have for the time being.

Check if you have the folder /data/media/TWRP and either delete it or move it to /data/media/0/TWRP

@F4uzan You had the right answer i couldnt find any other solution . In the end i formatted everything from fastboot. Thanks anyways

Do a backup of anything you need to keep in TWRP to an external drive (SD card, USB or PC) if you haven't got these you will have to backup, reboot, then transfer to cloud (Mega = 50gb free)
Then do a FULL wipe (everything), go back to wipe again but don't select any partitions just click the FORMAT DATA button, this will completely format your phone to factory again with no forced encryption etc etc, only the original 3 GB system image left, then you just need to re-flash your chosen ROM again and restore anything you need from your backups.
Hope this helps.
