[Q] Need help! Why are all my dev/mmcblk files 0 bytes? - Sprint Samsung Galaxy Note II

I asked this in the general android forum yesterday but no one seems the know the answer. My phone was unwittingly hard reset. I thought I backed up my internal memory but it turns out I didn't!! AHHH!!!
My only hope is to try and recover my internal memory.
I followed this guide HERE
Everything works perfect except the mmcbil files contain nothing in them. I looked up the "/dev" folder with a root explorer but all the files in this folder show 0.00 bytes.
I have a Note 2 with Android 4.3
What should I do?!?

[Q] Free space after flashing new rom

Hello everyone,
I've been trying several different roms and I found my free space dropped to 1.7 gb on the internal memory. Is there any way to make sure I get the original free space back? Like formatting the partition and flashing a Rom or something like that? I've tried wiping caches and such, but I still think I've lost like 3gb out of nowhere. Although I would like to know what the average free storage space is first.
Please help a total noob!
Thanx
I assume you haven't deleted the old roms off your phone?
If you plug it in via usb you can view the storage that way (in mac [android file transfer]/linux/win). Just delete any roms you're not using etc.
It seems that you need to erase your storage to get it back. When flashing rom we didn't do storage format, files and folder from old rom remain there. This folder could be your content like music and pictures, also some remaining app folder
If you use a Linux computer to delete files on your sdcard then check your sdcard for a .Trash directory (the name might be different, like .Trash-1000). Even though you thought you deleted some files they just got moved to .Trash and are still there taking up space. If you delete the .Trash directory it will really get rid of those files and give you more space.

You're totally right. I just deleted some old files from games I don't even have like FIFA.

[SOLVED] Where did all my storage go? CM10.1

[Q] Where did all my storage go? CM10.1
Hi all, I'm currently have a problem finding out where all my storage space has gone and what is safe to delete.
I'm on CM10.1 and the storage indicator in settings is attached. It says I only have 888MB available but the graphic shows around 2/3 of the internal storage is unused
I found 3 folders (storage/sdcard0, storage/emulated/0, and storage/emulated/legacy) that are both 2.62GB large. They look to be identical copies of /sdcard.
are any of these folders safe to delete? I am running out of memory and I believe these folders are the reason why.
Thanks!
Only yesterday someone mentioned something similar somehow. So I don't think that thread is really far away if you checked the first few pages in this Q & A section.
By typing in the searchbox "4.2 storage", I got this thread as the first result. So please try searching harder next time
Feel free to explain further if your issue is not resolved using the above link
Do not delete those folders. They are merely symlinks and not taking up any extra space.

Thanks for the reminder to search more, I will remember to do so in the future.
I thought they were symlinks because changes i made in sdcard were reflected in the other folders however when i check the size of the storage folder I can see that the total size is 7.87GB. If they were symlinks wouldn't that be 2.62 gb? I will continue to search for how to fix this issue.
I don't think the problem is an app because that would show up in the storage graph under settings would it not?
thanks!
found this thread that seems like a very similar issue
http://forum.xda-developers.com/showthread.php?t=1906449&highlight=storage
however again I see a discrepancy in the used storage vs per app usage. The SD card Analysis is attached.
On my GNex, the storage/sdcard0 is of size X, and it is the same X size for each of storage/emulated/0 and storage/emulated/legacy. This is very similar to what you originaly mentioned in your first post. I was just checking mine as well.
Hmmm, is this only happening with CM 10.1 ? Any other ROM you tried ? A reboot could help?

Check how much storage is used by your nandroid backups. I know that those aren't reported on the Storage space screen.

This is true for mine as well. The size of the /storage is 3*X. Good to know this isn't problem I am having.
AOKP gave me the same problem earlier. I have rebooted and wiped data... Is there any other folder i can check?
I've attached another screenshot of the sdcard analyst in es file manager. This is very confusing to me that the directory size is 2.48GB but out of a total 13.33GB space only 1.01GB is free?!

I am not complaining of any problem. I was trying to help the OP
Anyway, the ES File Explorer "SD Card Analyst" seems to include the nandroids as well

Just to confirm, do you remember making any "hidden" folders on your sd card?
Actually SD Card Analyst should by default show hidden folders as well but I thought it is bettER to ask you and be sure

No, i don't recall intentionally making hidden folders.
and if the nandroid comment was directed at me, I checked the CWM folder where I believe they are saved. I only have one nandroid backup currently and the size is 1.25GB,
What do you have in /data/media/ ???
I have 3 folders there: 0, legacy, obb
the "0" folder seems to be another symlink as well.
I am trying to find anything on your sdcard different than mine. That's why I'm asking

This is very strange, my /data/media/ is very different from yours.
I have the same 3 folders you have: 0, legacy, and obb however I also have what seems to be an older /sdcard backup. There are folders in there that seem to be from before I wiped data.
The 0 folder also appears to be a symlink but unlike the other symlinks this one takes up no space. In fact none of the folders in /data/media take up any space. When I check the size of /data/media es file explorer says it contains 0 files and 0 folders???
Thanks for all your help so far! I will keep searching
Yes it does not show any size with me as well but I can see the same contents of /sdcard/ in /data/media/0/ .
Would you please explain further about that "older" /sdcard/ backup you mentioned?
I am starting to think that maybe the first few times you went to 4.2, you did NOT have the latest TWRP or CWM installed. So the sdcard files were moved inside a "0" folder each time, then maybe you transferred your backup from PC to /sdcard/ so it became duplicated. Sorry I am not sure I am clear enough in explaining this but it is just an assumption because something similar happened with me before this "0" folder issue was fixed in TWRP actually.
Maybe I can help you bettER if you explain to me more about that "older" /sdcard/ backup you found

This was immensely helpful. You are correct, I had stock 4.2 on my GNex before I got CWM. This will get confusing but I will try to explain what I see in /data/media
/data/media/0/ seems to be a symlink for sure. however the other folder in there are from before wiped data earlier today. /data/media/download/ has a file I downloaded last week however /data/media/clockworkmod/backup has backups as recent as yesterday. I believe these are app data backups because I recall 3 of them. I do not see the nandroid I recently created in this folder. Is there anything you need to know?

Well, I think that "everything" you already have on your /sdcard/ including "clockworkmod" backups, blobs, and so on, should be duplicated (as symlinks) in the /data/media/0/ not in /data/media/. At least this is what I have in my sdcard. This should be the same for /data/media/download/ because the "download" folder of your /sdcard/ should be duplicated (again, as a symlink) in the /data/media/0/. Therefore, you said there are "backups" for clockworkmod in /data/media/clockworkmod/, so assuming the backup would be around 1.5 to 2 GB, then 3 backups of these would be about 4.5 to 6 GB of storage.
Please take note that I have "never" messed with these files and my above thoughts may be incorrect, so maybe first you may try to check whether these clockworkmod backups are really consuming a lot of storage. If they are really consuming that much storage, then it is bettER to play it safe by taking them out to your PC first just in case deleting them would cause something wrong. I hope some other more experienced member can "confidently" tell you to proceed in either deleting this /data/media/clockworkmod/ or suggest another solution. Sorry but I would not tell you to do something unless I am very confident and sure of it. I hope you understand
I will try searching for an exact answer on whether this /data/media/clockworkmod/ is safe to delete, and if I found something then I will let you know for sure
I made a nandroid backup and deleted all files in that folder except for 0, legacy, and obb. checked my storage and now I see 9.65GB available which is fantastic! I still have 1.18GB unaccounted for but I now that I know what seems to be the issue I can go through the rest of my data and try to weed out the problems.
Thank you so much for your help!
WOW! Glad to hear so
That was a brave thing to do. I would have done it if it is my phone but would not suggest for others unless I am sure it won't cause any trouble
It would be great if you mark/edit the thread's title as "[SOLVED]"
Well Done! :highfive:
In hindsight it was not my smartest move Thanks again for all your help!

Here's what worked for me.
1. Make sure your phone is rooted
2. Open ES File Explorer
3. Press the Menu key > Tools > Root Explorer (grant it super user premission)
4. Some dialog pops up. I didn't understand the options, chose R/W permission and then pressed back at the next screen
5. Go to the root directory "/" and then "/data/logs"
6. Delete all the files in there
7. Thats it! :good:
There was about 1.6 GB of log files in there for me. 1440 files about ~1.5 mb each.
(Strangely, a huge number were from the 26th of last month, then 1 on the 27th, 30th and then all the rest from the 14th of this month?)

Where did my storage go?
A huge thank you R !!!
been breaking teeth & puling whatever little hair got left for ages trying to solve this, mostly with complicated & futile suggestions. But yours worked right off the bat ! God bless you.
although i already had to go back twice within hours and wipe all files again its probably because i restocked on all those apps i had to delete before due to lack of space. At this point i'll take any solution over none.
if anybody ever rights a code that will prevent the dumpstate from accumulating he'll have a serious karma !

Help I deleted all my files!

So I did a factory reset to try and free up some space but i didn't know it wouldn't. So I went in and saw that my legacy folder was the same a my emulated and sdcard0 and all that so I figured it was coped into several directories. Without thinking or google I deleted it. Big mistake. I cant get anything back. Everything is gone. obb and everything is gone. Downloads folder gone, everything. I did notice that if i start installing apps it add things like my android folder back in. All the other files are there in the home directory. The problem is in my /storage. in storage I had /storage/emulated /storage/sdcard0 /storage/usbdisk they all had the same files so that's why I deleted it. I feel so stupid because i always read about things before I do them for this reason. ANYWAY, my question is. Is there anyway to get my folders back. I don't care if its just the ones that come with the android out of the box. If i have to put them back manually then i guess thats what I have to do. Is there any work around or anyway someone could help me out get these dam directories back. If your going to tell me to use search don't bother because i already tried, unless you can give me a good search query to use.
Go into the android development section and use the tool to recover your tablet. It works great.

SDCard0 Weirdness

Hi guys,
I noticed awhile back that my internal memory was almost full. This is odd since I have an external SD card and I put most memory intensive stuff on there. Even after flashing a completely fresh ROM I have almost 9GB of internal memory consumed.
While sniffing around in ES File Explorer I noticed this strange nested SDCard0 file. In total there are 5 levels of nested SDCard0's....
Within the SDCard0 on the first screenshot, which is within my main SDCard0, (SDCard0-ception!!!) there is 6.91GB of information.
I'm guessing that somehow through flashing ROM after ROM over the last year or so I've got a buildup of old files. Honestly, I have no idea what's going on. Is it safe for me just to delete that 0 within the 0?
Any of you have ideas?
Thanks in advance!
Yes you can delete them except for the root folder. You should really use the search function. I just typed in '0 folder' and got 56 threads in this section talking about it, now 57 with yours.
Search is your friend..

[HOW TO] Recover deleted files from Internal Memory

Recovery Procedure below after my short story
===========================================
Hi Guys,
Just wanted to share my experience in recovering folder from internal memory of Hercules SGH-T989D.
I backed up WhatsApp folder to my computer however, it did not copy and I did not bother checking [my mistake]. I kept flashing nightly and formatted it 5 to 6 times.
Once I was done flashing the new ROM I noticed that WhatsApp folder was empty and wanted to recover it. I tried Undelete app but that did not return anything I tried DiskDigger returned pictures which I didn't need as Google Photo+ already backed it up for me. ( You guys should set up auto backup as well very good feature )
So I searched online and found ASoftTech Android Internal Memory Recovery post which was awesome. However, it lacked couple of things which made it difficult for me. It was mostly missing how to configure ADB.
I have listed the procedure which I followed and recovered my files I needed. I hope it helps someone else.
==============================================
I am providing link to PDF to dropbox. I could not attach it as it was exceeding the attachment size limit. Hopefully someone can make a mirror to this file.
