Recovery help needed

I did a wipe with Aroma installer and now my external storage won't show up in TWRP. It shows up if I boot all the way to Android, everything is still intact, but it won't show up in TWRP.
EDIT: I'm only having problems with TWRP, which is especially annoying since that's the one I used to make the backup. CWM seems to work fine.

Hi,
If you haven't got a folder called "0" on your Internal memory, create one and put all flashables and other such files into it.
That "0" folder is a 4.2.2 feature and even though our phone is only on 4.1.2, this version of TWRP was built using CM10.1

I do have that folder, but it's nested within /data/media. Should I move it to root?

I'm not sure why it was there, but yeah move it to root and it should be fine.

Now I have a much more serious problem, as you can see here: my new problem

Flashing an 4.2.2 rom and file structure issue.

I decided to start this thread as both assistance for some as well as a collaberation on workarounds when you a person flashes a 4.2.2 rom coming from a 4.1.2.
Just like some (maybe most) I flashed CM 10.1 and played around a bit with it and decided it was just not ready to be run as a daily. Being the flashalohic that I am, I made sure I backed up before flashing CM 10.1 so when I went into recovery and went to restore imagine my surprise when it was blank, yep nothing was there. Why did this happen? Well doing some research and reading/searching I found out that the update from Android 4.1.2 to 4.2.2 changes the file structure of the 'virtual' sdcard on our devices. Actually it changes it for every device. What has changed is that the ability to add user accounts, similar to any regular computer, has been implemented. However, if the proper steps are not taken before you flash a new 4.2.2 Rom, you will end up with a huge mess and run out of room on your device in a hurry.
The actual location when viewed with a root file manager has been here on 4.1.2:
/data/media
And though you will see the same files in /sdcard and /storage/sdcard0, those are just symlinks to the same info, just like a shortcut (on a windows box) or alias (on a mac box). Once you flash a 4.2.2 ROM, the actual location gets changed (and all the files moved) to here:
/data/media/0
And the symlinks get changed to /sdcard/0 and /storage/sdcard0/0. On the surface, no big deal, right? Wrong. The problems arise if the version of your custom recovery is not compatible with a 4.2.2 ROM. If it is not and you keep flashing 4.2.2 ROMs you might soon end up in trouble. If, while using the 'older' custom recovery, you continue flashing, your sdcard ends up somewhere around here:
/data/media/0/0/0/0/0/0 (etc.) with all your files copied to every '0' directory and your symlinks end up the same way, and your device quickly runs out of space (the dreaded "your device is low on storage" message).
This may also make it very difficult to restore your nandroid of a 4.1.2 ROM as well. If you are already in that situation, not to worry, the solution for that is later in this post.
So far I have only been able to to copy all the files found in the last /data/media/0/0/0/0 (?) folder to my computer. Then using a file manager that will show hidden files and folders, copy/move the files in the last '0' directory to:
/data/media/0
And then use file explorer to delete all the other '0' directories until I have just this one:
/data/media/0
leaving nothing else in the symlinks but /sdcard/0 and /storage/sdcard0/0. This techniques is if you end up with a huge file structure.
****BACK UP YOUR SD CARD FIRST!!!!! before deleting any 0 folders!!!****
NOTE: A reboot of your device is essential at this point.
If after flashing a 4.2.2 ROM you decide you don't like it and want to restore your nandroid to your saved 4.1.2 ROM, how does that work out?
1.) Get yourself a (good) root file browser.
2.) Brows to /data/media/0
note: this is where android (and almost everything else that uses a Linux kernel) mounts anything that is considered "external" storage.
3.) Do all of your file fixing from here. It will make changes universally.
4.) select all within /data/media/0 and then paste everything back into /data/media selecting merge and/or overwrite. Once done, just delete the /data/media/0 folder, reboot your phone and Profit.
This is a pain and I agree but at this point is the only way I know how to get around this. If anyone knows other ways please share.
* While writting this I came across this info from user elfaure. I havent tried this yet as I am at work and get crappy signal but please post results if you try and if it works, please thank him! *
elfaure: Ok folks for next guy who decides to upgrade to 4.2 but does NOT want the multi-user environment, give this a try.
1. Download the attached file
2. Remove the .txt extension
3. Copy it to your /data directory
4. Open Android Terminal Emulator (Free Market app if you don't already have it)
5. At the prompt type "cd /data"
6. Type "chmod 644 .layout_version" on the file in /data (/data/.layout_version)
Code:
cd /data
chmod 644 .layout_versionNow when you upgrade to 4.2 you should stay single user and have no /data/media/0 directory when you are done. If anyone tries this please let me know if it works and thank me if it does.
ps-its just a special file in a special location, the presence of which tells Android NOT to upgrade your system to a multi-user environment. If you later decide you want multi-users, delete the file and reflash (from recovery) the stock or custom firmware or ROM or recovery. If your custom ROM or recovery wipes the entire /data partition less /data/media including this file, obviously then this will not help, but with latest versions of ROMs and recoveries that should not happen any more.

It also looks as if he may be working on a script to help as well and I will keep track and update as needed.
So far this is what I have come up with and I hope it helps some and I hope others that are smarter than I can correct me if I am wrong on any of the above or other add information on other ways to correct this.

I think this is part of my issue but I don't have any 0 folder under data?
I too flashed the 4.2.2 ROM, and noticed that every everything on my sd card had somehow moved to my internal memory? When I went to reflash the ROM it failed. It I also tried to reflash the ROM I was originally running and it too failed. Luckily I was able to do a nandroid restore so the phone is "usable" but TWRP 2.5 still does not see my my external sd and that seems to be that make reason I can not do anything within in the recovery.
Any suggestions?

The op is telling you exactly how to fix it.

Let my clarify:
I have used two different file managers and even used to terminal emulator using ls -la to make sure i have no hidden files
sdcard0/data/ there is no media directory
Maybe this isn't my problem, since I don't see any file/dir with a 0, but all this mess started when I loaded up a 4.2.2 ROM?

Everyone should check this out to aid you in your flashing addiction.
Happy flashing!

Good information

so does this work? will i be able to nad back to sense and all my files are in the right place?

I couldn't get it to work, the attachment. However the new recovery I linked to looks to have promise but I haven't tested it yet cause I'm remote right now and need my phone at the moment. Will give it a go this weekend.

Weighing in, worked like a charm for the most part. TWRP recreated another TWRP folder inside its original TWRP folder (it has to be left at /data/media/0/TWRP for you to be able to reinstall a nandroid backup) [also forgoing obvious yo dawg joke here], but besides that my phone is back to being right as rain.

Nice write up on this issue. Thanks

I'm sure it wouldn't work for doing a nandroid restore, but on my Galaxy Nexus I would just make certain I had the latest version of TWRP, boot into recovery, format the SD card, and then push the rom files to /data/media/ and flash. That is my only complaint about this change, really...truly "clean" installations are inherently more risky or difficult, dependent on your knowledge level.

It won't let me delete folder 0 no matter what. Inside that folder is a ViperRom folder that won't delete as well no matter what I do!

Thanks for this info. I think I'm going to take the plunge this weekend so this will be very helpful info.

I think it moved my ROM data into the 0 folder, how do I get it out? Everything else from the 0 folder is deleted except for ViperROM's folder, and whenever I try to move or delete it, it just fails the operation. I already have a copy out of the 0 folder, but I still want it out, because otherwise I can't flash things, since it just shows the the almost* empty sdcard/0 folder. Help? Should I just put my mods in the 0 folder and deal with it?

So can we delete the legacy file now? I haven't done anything with my internal storage since coming from 4.1.2 for the first time. It looks like twrp 2.6.3 copied all my files correctly to the 0 file but all the files are still also in "legacy" folder. Is it duplicate that I can delete from legacy or are they just symlinked? I am never going back now that we have official 4.3 release.

I am not certain to be honest. It looks like the file structure didn’t change with the release of 4.3 so it’s possible that they are symlinked. If all your files are moved to the /0/ folder and you have nothing in the legacy folder it would make sense that you would be able to but I have yet to test this.
I suppose this weekend I could back up the phone and file tree and give it a shot

Thanks for the response. I haven't tested out yet either but will post back if I do.

[Q] /sdcard/0 new folder being used as root and /sdcard wasting space

Ok so, this is a bit hard to explain, I can only take SS's of some of the problem. So a while ago I installed android revolution hd 10. I've since upgraded to 12.x. I noticed sometime inbetween then. That when I go to clock work recovery I am always greeted with the contents of my sd card before I installed the ROM, I have to click on a folder called '0' which is in my sdcard folder. so /sdcard (this is where all my old data is)/0 (then '0' is where all my new stuff since I installed revolution is. To access the location where all of my stuff saves.
So this is the highest level I can get to on my computer and with root browser/es file explorer on my phone: http://gyazo.com/7a3831c0d9934732b8dc5b2e700e422d
But, when I go into recovery I am greeted with this:
http://gyazo.com/13baa0cb30a21c0fb83db3a35965ced3
see how at the top there it says /sdcard That is full of all my old files. and here when I click on /sdcard/0 : http://gyazo.com/8d39545d7561de02452ef3964e4df6fc
You can see at the bottom of these two, a little window into the past. Because my phone has been using this /0 folder as root I guess? So what is going on, it's using about 8gb or so, maybe more idk, has all my pictures and stuff. And I can only get to it in clock work recovery. Which I don't understand.
Hope you can make sense of this. I'm Australian which is why I'm posting now. time zone is incredibly annoying I hardly get replies. Thanks though

actually, youve got a great time zone. Most americans are still awake at this time. its 22:45 for me on the east coast of america and 19:45 for anyone on the west coast. anyways. i assume its been doing this since you uprgraded from a 4.1.2 ROM? its still kept this because when updating from 4.1>4.2 it creates user profiles, and all original data gets pushed into a seperate section. download a root explorer app (the most popular on GPlay will work for you) and go to the directory /data/media/ and you should find not only the "old" files you had but the "new ones" too. delete things how you feel need nessesary,

all i have folder wise is
/0
/clockworkmod
/legacy
/obb
and file wise as
.htc_layout_version
recovery.log
revolution_hd.log
other wise you should be good to delete anything in the /data/media/ path. (take a nandroid, then do your deletes, reboot, and if your phone still works fine, now you know the path to delete the backup in file explorer )

Hey, so. When I try to delete the folders and files, I've tried in root explorer, root browser and ES file explorer. I select them and then delete. But it doesn't work. Everything just stays there.
Thanks.

[Q] File structure questions

Hi all,
And yet another noob question...
The problem of being this ignorant, is that it is also hard to ask a good question. So I'll have to tell the story in full...
I started to use custom ROMs only one month ago. I installed and configured CWM 6.0.4.5, and through ADB PUSH to /sdcard/ I put the files for CyanogenMod 11 "cm11.zip" and "cm11_gapps.zip" into my phone. I was able to install this ROM, so no issues there.
After some time of playing around, I felt that some bugs in the ROM were unacceptable to me. I also got errors that stated that my memory was full, although, when I looked into ES file explorer or even the standard 'Storage" tool in android, my phone appeared far from full (+5 Gb free!). To me, that was the drop to remove this ROM (althoug I already found out that it was not the ROM's fault...).
So I installed another ROM, CM10.1.3. Again, I ADB pushed the files "cm1013.zip" and "cm1013_gapps.zip" to /sdcard/ , rebooted into recovery. There I did the following:
- install zip
- choose zip from /sdcard
At this point, I thought I would find my files "cm1013.zip" and "cm1013_gapps.zip", but I didn't! Instead, I did find the previous files "cm11.zip" and "cm11_gapps.zip"!
However, I did see a folder "0/", so when going into that one, I did find my files... So I continued the installation of my ROM, no issues.
But now, when I use ES File Explorer, I can't find these "cm11.zip" and "cm11_gapps.zip" anywhere! It seems like once I'm in my ROM, I can't access a complete part of my memory.
This means I lost a big chunck of my internal memory!
What did I do wrong, and more important, how can I resolve??
I tried my best to search this forum, but all I came up with was this thread:
http://forum.xda-developers.com/showthread.php?t=2304138
Interesting, but not a solution to me, as I'm unable to even find the files in the first place.
All help much appreciated, and sorry for the (too) long explanation.

By the way, when installing my second ROM "CM10.1.3", I used every "wipe" option in the recovery mode I could find:
wipe data/factory reset
wipe cache partition
wipe dalvik
I thought that was the cleanest I could get...
When wandering through ES file Explorer, I always end up at the same location for sdcard... There are so many ways to get to my memory. I understand the principle of symlinks, but I don't understand the meaning of "emulated".
All of these paths, end up on the same location:
/mnt/sdcard
/sdcard
/storage/sdcard0
/storage/emulated/0
/storage/emulated/legacy
What is the "emulated" locations for?? But the files I'm looking for "cm11.zip", can't find it anywhere (see post above)...

after looking for some more, I finally found the files I was looking for. They were stored under /data/media/
So, when booting into recovery mode with CWM, and choosing "Install zip", this is the folder you look into.
I'm still puzzled by the fact that while doing ADB push to send files it ended up under 2 different locations while running another ROM...

Can't move TWRP folder off phone

I recently unlocked my bootloader using sunshine and installed TWRP. After rebooting into recovery, I immediately made a backup of my phone. When I plug my phone in, I can see the TWRP folder, but it shows as empty. None of my file explorers can see anything, either. TWRP, however, is able to see it when I go into the file manager. I can't get ADB to see the device when hooked up to my computer while in TWRP. MTP also doesn't work. Chmod 755 and 777 doesn't do anything. I was able to initially copy the TWRP folder into the downloads folder in the TWRP file manager, but now it just hangs there if I try to move it again.
How do I get access to my backup?

TWRP and NAND Backups
I had the same question, and found the previous thread too. So what's the difference between these 2 locations?
/data/media/0/TWRP
and
/sdcard/TWRP
From my point of view, they are duplicates - same data in both folders, just duplicated into separate partitions. If this is true, then my 7.5 GB NAND backup, is really taking up 15GB of memory. Can that be true? I'm doubting it, but you never know.
I started to dive into this, because I was also wondering if NAND backups made copies of my media or not (photos, music, etc). After digging into it a bit, it looks like it does NOT make a backup of anything in the root folder "/data/media" in order to prevent it from non-stop backing up in a loop (you can't back up the location your backing up to, at the same time). This is also noted on github: https://github.com/TeamWin/Team-Win-Recovery-Project/issues/276 Logically, this would make sense since I currently have 25 GB of data in my /sdcard/ location. That's one helluva compression if you were able to get this down to 7.5GB! So I'm guessing this isn't included, which is also why I'm guessing that these are really the same. /sdcard/ must be a shortcut to the /data/media/0/ location, that's my best understanding.
So my original question still stands. What's the reason for these 2 locations, and is there a difference?
This also brings up the next question, what's the best way to make an all-encompassing backup? NAND + Titanium Backup + copy all the contents of your /sdcard/ over to your computer (or OTG drive)?

The way I understand it, and I might be wrong, is that before Android 4.0 (or maybe 5.0), the partition containing user data was called /sdcard and apps were stored in a separate partition. The partition where apps went was significantly smaller, which could result in people running out of space for apps while still having a ton of free user data. To remedy this, the newer version of android places apps and user data in the same partition (called media). The /sdcard that you see is a symlink (shortcut) to this new partition, and is included so that older apps that were designed to expect the /sdcard partition to be there will still work.
