Hi everyone,
I need your help. I sometimes face strange issues with my Nexus 4 (Stock Room, Rooted, Matrix Kernel v5). Yesterday I wanted to copy a apk-file for installation on my phone from my home-server. I use ES File Explorer for that. I failed to copy the apk-file to /sdcard/folder-name (operation failed). then i navigated to /data/media/0/folder-name and tried it from there, also it didn't work.
i then copied the file to /sdcard/download and was able to copy it to that and to install it.
i don't really understand why it behaves that way, i was always able to go to /sdcard/folder-name and do what i want. i also noticed another strange thing. i connected my phone via USB (MTP-mode) to the PC and uploaded a few GB of MP3s to it (Folder: Music).
when browsing this folder with ES File Explorer, I cannot delete anything from that folder /sdcard/Music. THOUGH it reports "deletion successful" the files or folders do not get deleted but just remain on the internal SD-card. i could only delete the music successfully via "/data/media/0/Music".
who can explain briefly WTF is going on? i obviously do not really understand the concept and logic behind this. is there a maximum file/path length that must not be exceeded?
thanks in advance and best regards,
hallu
need to bump this, sorry...
does anyone have any idea as to why this phone is behaving the way it is?
I use root explorer and have ZERO issues. That includes pulling apk's.
Try a different file explorer to see if that makes a difference so at least you can determine if the issue is just app specific and not something else.
Check to see of ES isn't mounting certain folders with RW permissions.
Also the actual internal storage is /data/media/0/ so /sdcard/ is just a symlink to that folder. ES seems to be having problems with the symlinks.
Okay, before I delve in, I will say I did try to find an answer to my noob question, and did see some posts about similar stuff, but really didn't find an answer and much of it was too technical for me. So . . .
I've been downloading photos to my Nexus 7 using my OTG cable, and placing them in folders like:
(sdcard) /storage/emulated/0/pictures/my images/
I noticed when viewing in my file manager app, that these folders (with files) seem to get copied/emulated in a 'root' folder:
(Root) /storage/emulated/Legacy/pictures/my images/ (It looks like the same string, but '0' is replaced by 'legacy' and of course its in the 'root' directory, not 'sdcard'.)
Three questions about this:
I wonder, are these files and folders being copied, so they're taking up more storage on my device, or are these 'legacy' folders virtual, and only look like they've been duplicated?
When I go to view my images in the Gallery app supplied with my N7, it sometimes shows both 'versions' (including the 'legacy version in the 'root' directory) of the folder(s)/files, and sometimes it only shows one version--the one I created. I can't tell, why is it doing these two different things?
And, to remove this duplicate folder from the Gallery view, I have to temporarily copy over the files to another folder, delete the folders they were in and recreate a folder to copy the images back to. So, is there a way to not have this happen in the first place?
Thanks David.
have a recently rooted nexus 4.2.2 and did a nandroid backup using clockwork recovery. clockwork stored it into a directory which i can't access by just plugging my phone to the usb cable of my pc. i do see folders, but not that particular folder. i have usb debugging option turned on also. i just wanted to transfer the backup files to my pc for storage. is there a way to do this? thank you.

You can't see it because windows can't access those folders. You can either move the backups using a file explorer to a folder windows can access, pull the files using ABD or if you have the paid version of ROM Manager you can download the files to your pc using a browser.
I figured it was something of that nature. However I have downloaded different file explorers including the es file explorer and I still can't see the folders on my phone even, not just pc. But when I boot into clockwork recovery and browse through there I can see those folders. I'm at a loss.

With ES File Explorer I had to turn on the root explorer option in the settings, the world and phone icon at the top left..

yes, i did that as well, but it still doesn't let me see the directories that i see in clockwork. the directories i'm talking about are in /sdcard.. they are
- 0/
- clockworkmod/
- legacy/
- obb/
the only ones i can see are 0/ and legacy/. if i go to 0/ i can see what i normally see in the pc windows explorer. there is also a folder called clockworkmod/ but it only contains the folder called download/ and a couple of files under 100kb.
also, when i'm viewing the folders in ES file manager the sdcard folder has a little shortcut arrow on it instead of a solid folder like most of the other ones.
I can't speak for the intricacies of Clockworkmod as I have never used it, but after doing either a TWRP backup or a Titanium backup on 4.2.2, I have always been able to copy and/or view these backup files using any of the following methods, as well as verifying that they are equivalent (Same exact number of files, same exact file sizes):
1) Copying the files from the Nexus 4 to Windows 7 64 bit Professional using Microsoft Windows Explorer.
2) Copying the files from the Nexus 4 to Windows 7 64 bit Professional by performing an "adb pull".
3) Viewing the files with the Android ES Explorer app (With the "Root Explorer" option turned on and changing the top directory to root or "/").
4) Viewing the files in TWRP.
I also use the full path to the files (when possible). As I recall, there were instances where not all the files were visible if I didn't use the full path. Replacing /0 with /legacy on Android 4.2:
TWRP BACKUP
/data/media/0/TWRP/BACKUPS/<PHONE SERIAL# HERE>/<FILE BACKUP SUBDIRECTORY HERE>/
TITIANIUM BACKUP
/data/media/0/TitaniumBackup/
In fact I just performed all four of these methods a couple of minutes ago because I was originally having problems with Android 4.3 (Not all files being transferred over due to the known permission changes with 4.3), and I wanted to double check that everything is still working properly now. What solved all my issues with 4.3 was to update all my programs to “4.3 friendly” versions (You could see if this resolves your 4.2.2 issues as well):
1) Installed the latest version of TWRP.
2) Unrooted using the latest version of Superuser.
3) Installed the latest Android SDK and then ran the SDK Manager to insure everything was up to date.
a) Deleted my Windows driver and installed the latest Google USB driver from the SDK.
b) Used the new updated platform tools to perform fastboot, adb, etc.

the thing is i can't see the directories that the files are in. either in file explorer or in windows. i need to get more familiar with adb and maybe do it through that, but its strange because i should be able to see them in the explorer. so essentially i have a nandroid backup on my phone that i can't really access to move it or delete it. i can only access it through clockwork recovery. also, all the stuff i used is the latest versions i.e. sdk, drivers, etc.
Then I am at a loss if you tried all the things mentioned. If it is a permission issue, then adb should bypass that problem. The adb executable is located in the platform-tools subdirectory of the SDK. You run the "adb pull" command from a "Command Prompt" window while located in that directory. The nandroid copy will take quite a while, so wait until it is finished (For example, my latest one was 330 MB in size).
While the phone is in recovery, here are some examples of grabbing the TWRP and TITANIUM backup files and putting them into the directories TWRP_BACKUP and TITANIUM_BACKUP respectively (That I previously created) on the windows "C" drive. As before, you would probably be replacing /legacy for /0:
adb pull /data/media/0/TWRP/BACKUPS/<PUT SERIAL # OF PHONE HERE>/<PUT DATE OF BACKUP HERE>/ C:\TWRP_BACKUP\
adb pull /data/media/0/TitaniumBackup/ C:\TITANIUM_BACKUP\

Clockworkmod puts the backups in a secure system folder with the path mnt/shell/emulated/clockworkmod/backup. In ES File Explorer hit the "/" at the top which will open up "device" and now you will see all of your system folders. Root Explorer is a simpler app to use as it only has two directory options, root and storage. I bought both apps a long time ago as I liked that ES File Explorer lets you connect to a lan to upload/download files through wifi.

i have root explorer that i purchased a couple years ago as well. doesn't show me the path you mention. neither does the ES File Explorer. this is why it puzzles me since my phone is rooted. when i look in ES File Explorer and choose "/" as my starting point, i do see all the folders, however, the clockworkmod folder doesn't contain the "backup" folder. it has only "download" folder and a couple of files ".recovery_version" and ".settings".. nothing else.

I looked in su and I have three apps listed there: root explorer, titanium backup, and es file explorer. I don't see those folders that you have in your screenshots. What app do you use for that? I'll take a screenshot of what I have.
Edit: I reinstalled the file explorer and rebooted the phone and I can see the mnt directory now. Don't know why it wasn't showing up. Thank you for the help.

Glad you got it worked out. To take screen shots press and hold the power button and volume down at the same time. My photos automatically upload to dropbox and I just attached them from there to my post.

Happened to me aswell
all you need to do is go into your file browser on your phone and then move the file somewhere else while still connected to the pc.. should be good then
Hi all,
I've decided to try and copy my nandroid backup that I made the other day (first ever since I've just rooted my phone) to my PC.
Long story short, I attempted to use Root explorer to cut and paste the backup's folder into a folder that is visible on my PC so I could get a copy onto my PC, and then cut and paste the nandroid back into its original folder (tedious, but I don't have enough space to have 2 copies of the nadroid on my phone at the same time). This, however, fails, and I can't see the backup folder in the folder that I can see on my PC despite it being visible in this same PC-visible folder via root explorer after its supposedly pasted it.
So I went via option 2, using ADB to pull the folder.
After another amount of research I found a path that does pull the folder (mnt/shell/emulated/clockworkmod/backup .... data/media/clockworkmod/backup = remote object doesn't exist error).
It appears to pull the folder successfully (an identically named folder appears in "platform tools" folder on my PC), however the size of this pulled folder is only ~500mb, and I'm certain the nandroid backup took up at least 3-4GB on my phone after it was created.
The pulled folder also doesn't show all the files that I can see within the nandroid backup's folder via root explorer.
I did notice the "read-only" checkbox of the pulled folder appears filled in, which I take it means not all files in the folder have read-only properties. Is it possible there are (still) hidden files within the pulled folder that would account for the difference in size and number of visible files compared to the original nandroid folder on the phone?
any clarificaion of this would be good - I'm keen to have a copy of my backup on my PC as a safeguard, but this scenario has baffled me despite an hr's worth of research
No one?
Surely someone has an idea about this..
I have experienced incomplete adb pulls also, and so I just stick to using MTP from within Windows. It's the only way for mention ensure a complete copy.

How are you doing this?
I use cwm and the backup folder isn't visible if I use mmtp (Windows file explorer etc), hence why I'm having to use other methods.

It's possible that the computer and phone may be calculating file sizes differently. I would check the MD5 sums to see if they are the same on the computer and phone rather than guessing

Apologies for my ignorance, but I've been searching how to do this via Google and I must be really dumb because I'm not following how to do md5 checks. Could you explain it please?

For Windows you need to download a program to check MD5. Microsoft has one available here, although it is a command line operated program. There are other programs that have a GUI for checking MD5 if you don't want to bother with the command line.
On your phone, using your file explorer and long pressing the backup should give you the option somewhere to calculate MD5 sums (Probably in properties). I don't know if root explorer does, I've never used it before, but I use Solid Explorer which does give me the option to calculate MD5 in the properties menu
I'm not sure why you're backup folder isn't visible, when I connect though USB, all my SD card folders are shown, including the CWM Folder.

After a while of trying to work out the command line, I've think I've got it (but would like confirmation that this is correct).
- Pointed the fciv.exe command to the nandroid.md5 file located in the backup folder I had pulled from the phone via ADB
- using Solid explorer (root explorer also has this but I only worked this out after I worked out that I had look at the properties of the .md5 file itself w/in the explorer app, rather than the whole folder), I found the MD5 sum from within the backup folder
-- verdict: both numbers outputted by each source match.
Now my next question is, if I were to delete the backup on my phone, how do I go about putting it back into the "hidden" CWM backup folder where it came from later?
(seeing as I wasn't able to copy it using root explorer, and can't see the folder via MTP on my PC)

I have no idea either, and its really really annoying me.
Have you made some sort of permission changes to the folder/s themselves?
I have "show hidden folders" enabled under view options in windows explorer and have tried "show system folders", but that hasn't resovled it.

You can use ADB push in recovery the folder. Just make sure you mount /data
I do have those settings enabled in control panel, but aside from that I'm not sure what else could be there. In terms of USB settings, I have USB debugging enabled in developer options, and in the storage menu I have mtp selected, not the other one. I think that is all the USB settings that I have changed.

The CWM backup folder shouldn't be able to be accessed with MTP. Android only allows you to access your user's folder (You can only have multiple users on tablets, but the user based file structure is still there) through USB. User folders have a number attached to them to mark which user they are for, which is why you have that folder named 0 with all your stuff in it, because you are user #0. Since CWM backups are saved in a separate branch, Android does not make them available to USB for security reasons. lolcakes203 probably has a modified version of CWM (Or you can change the save directory in CWM? I haven't used CWM in forever), or he has TWRP which saves backups in your user folder so you can access them through USB
Ahh yes I am using PhilZ CWM and that may be why I can see the backup.

Sorry, not sure I'm following the command line instructions - how would this command line look in full?
As title states, to access the obb folder, do I need to be rooted?
no you dont need to be rooted.
I dnt see the obb folder inside the Android folder.. its normally
Android > obb
what file manager are you using? Are you checking for the obb folder on the memory card or internal memory? What game/app are you trying to install that you need the obb folder?
S7 built-in file manager... and of course internal memory...
hmm it should be available by default try creating the folder and placing whatever game/app you want in side it.
doesnt seem to work... tried a few times with different app... just FCs
Out of interest, If you do not see it, You may not have an application thats created Obb.
This folder is not created unless a package is stored in here.
you can create it manually via file manager / file browser
(If you create it manually, there is every chance you need to set the permissions and assign it a group)
obb is owned by media_rw (Group id 1023)
The permissions on this folder are:
rwxrwx--- OR 0770 (Owner and Group Full read Write Execute)
If the folder exists and is hidden, the application will not allow you to create the folder.
Delete the folder and download one of the following from the store:
This should create the OBB folder
StarKnight
Brain it on
The Room 3
Thumb drift
Ilttle Drew
Odyssey
(Just some packages i have in Obb)

Im not rooted so I cant check/change permissions.. But I did install the thumb drift game and the OBB file showed up.. still just getting FCs
I'm using an s5 on RR 7.1.2 and I can't access obb. It's there but the folders inside are empty. And I can not move files into the directory.... I don't know why.
