Corrupt/Ghost backup files - Nexus 7 Q&A, Help & Troubleshooting

After searching around for similar issues (and finding none with MTP devices, all with USB Mass Storage), I have concluded that I need to ask here for help. I recently tried to delete an ond backup through a computer (Win7) and after I deleted it, it stll showed up on my N7. I've tried every method I can think of for deleting the files, but they always re-appear after I reboot. When I try to delete them through Astro the progress bar stays at 0%. The only articles that I've found with "corrupt file" and "mtp" as search keywords are articles about how mtp issupposed to prevent this from happening. Please help!

Have you tried to use Solid Explorer? It is much more advanced than any other file manager I have encountered.
Other than that, command line and wiping the partition.

Well, I still can't delete the files, but at least Solid is giving me a "can't delete file" error. I guess I'll have to try to back up my SD storage and reformat. Oh well. Thanks anyways.

Ok, if for any reason a standard re-format doesn't work, PM me, I have something which will do a bit more.

Problem with "MTP Application"

Hi,
today i wanted to connect my Galaxy S to Kies to check for updates etc. After connecting usb cable i chose on Samsung Kies on phone and "MTP Application" appeared. But phone couldn't connect to Kies. MTP Application was closing every few seconds and launching again. I reinstalled Kies but that not helped. Mass storage and Modem connection works fine. Do i have to reflash? I'm on JM5.
Do you have "Soundhound" installed?
No, i've never installed it.

Hello.I had that problem too with that firmware.The only solution i had was to format the internal sdcard and then mount it.So if u dont want to reflash just save your data and format it.And dont use launcher pro or adw launcher.They still mess up with mtp aplication as well.
Thx for suggestion. I'll try it in a minute.

Long file extensions
The problem is not only Soundhound, it's file extensions that are over 16 characters long.
You should browse your card manually and search and delete all files with long extensions.
You can find more info by searching "gizmondo galaxy s mysterieux bug trouve" on google.

Wow, i think it really worked. I deleted 2 folders which contained many files with long extensions (.aptoid for example) and it's working now. Thanks a lot.

Flash won't rewrite

The flash storage on my nexus 7 seems to not be rewriting like it should, when i pull it up in Windows i can see and delete things from the MTP interface. But when i use a file manager (OI File Manager) i can see the files once more and get an error when i attempt to delete them. i have done the Backup & Reset option within android after attempting a full data reset in ClockworkMod Recovery. At this point i am scratching my head. i am downloading another rom and will flash and post what i get from that.
Anyone else have this strange issue?
I've noticed this as well, anything I delete with ES File Explorer still shows up when it's plugged into my macbook but isn't actually accessible, I'm still on the stock ROM.

Nope, not even rooted, not really a big issue since I mostly use airdroid to transfer files but it would be nice to fix it.

The next thing i am going to do is return to stock, a complete re-flash to see if it empties the storage, I am posting all my theories so that anyone with the same issue could easily follow.
Success!
Using Wugfish Nexus Toolkit, my problem appears to have been solved. whether it is a perminant fix or not has yet to be known.

File system error?

I was copying a file from my computer to my nexus 7 and it didn't seem to be copying after a while so I stupidly unplugged it.
Now a ton of folders are missing from my main storage. Seems like file system errors but not sure what tools to attempt to fix it with.
Thanks for any help.
Decided to just backup and do a wipe and reset of my tablet.
Have you tried looking at them with ADB?

shows the same folders that my N7 mounted as a media device and File Explorer app shows. A lot of stuff is missing.
bump
I really wish I could fix my tablet :crying:
I'm scared to use it until I fix it.
Here's the folders it shows now, there were about 15 or so folders before, such as data, screenshots, videos, documents, downloads, and many others.
My tablet is rooted with clockwork mod recovery installed with motley anykernel nexus7 1.1.1 GPU 484 build 219

I've done the same stupid thing to a flash drive a couple times and windows check disk was able to repair it -_- I don't know what the equivalent tool for android would be though.
If I could only mount it to my computer as a mass storage device instead of a MTP device but N7 only gives you a choice between MTP and PTP
also hidden files makes no difference

[Q] USB Storage is acting weird

When I connect my Nexus 4 to my PC things get a little weird. I've attached an image to show my problem. Some folders (for instance TitaniumBackup) show up as 0kb files. Also, some files that I deleted like the LTEhybrid zip still show up in explorer. Trying to delete the file does nothing in explorer, likely because it doesn't exist. Sometimes I can't copy files to or from my phone. I'll get an error that my phone is no longer responding or the copy dialog box will simply disappear. I'm hoping this issue can be resolved without restoring to factory settings.
I should note that changing to PTP seems to function better, but I can only access DCIM and Pictures.
Debugging on or off makes no difference. I'm running stock rom 4.3 rooted, although I've had this problem for as long as I can remember. The file system works perfectly fine on any app on my nexus 4. Does anyone have any ideas as to what is wrong or how it can be fixed?
Thanks.
I've not found a way to fix as of yet. It's a bug in mtp.
A quick reboot will force it to update properly then you can get your files. But the bug will happen again

Rebooting does not help. I've tried using a program named MyPhoneExplorer which seems to work well. I can copy things to and from my phone's storage and everything is displayed accurately.
Would it be safe to assume it's a problem with windows and not with my nexus?

[Q] Strange issues with my storage...?

Hi all, first time asking a question on Nexus 4
Days ago I decided to upgrade CM10.2 from an earlier nightly (build number JSS15Q) to a newer one (JLS36C), so I dirty flashed and everything seemed fine at first, but:
1) When I connect my N4 to the PC, it links up in MTD mode, I can read, copy, rename and delete contents from it, but I just can't put anything into it. It says something like "device is offline or has stopped responding". I thought it was a random issue so I ignored it.
2) One day later, a nightly with build number JLS36G dropped, and I want to back up my data with Titanium Backup before I do a clean flash. I knew previously that to use TiBu on 4.3, the backup folder has to be manually changed, and this worked for me before. This time, however, even after changing folders, TiBu still reported "insufficient backup space" no matter what I do.
3) Yesterday I wanted to upgrade some softwares on the phone, but many installs fail with "out of space" alert, while I confirmed that I have plenty (5GB+) internal storage left.
4) And today I am using Root Explorer to manage files. I just want to move a file to another folder. I created the folder with success, but pasting operation failed, still because of "not enough space". The same happens for CM's File Manager.
Now I'm out of ideas. The best bet is to start over from a clean flash, but since TiBu is unusable, I will lose all my SMS/call log, which I can't swallow. I'd be very grateful if anyone can tell me what's behind all these issues, or/and can teach me how to back up SMS/call log with a file manager. Thanks in advance
***EDIT***: I figured out how to manually backup/restore my SMS/call log, and went on to do a clean install, but even after a clean install, Root Explorer still reports insufficient free space. I can install softwares normally, though.

are you sure you have 5GB storage left or available?

I'm pretty sure of that. I have 7.6GB files on the phone (calculated by copying all files out and checking their size using Windows), so free space should reasonably be 5GB. All softwares on the phone report this value too.

Exactly what method did you use to 'clean install' ?

Wipe cache, dalvik, data, system (yeah I'm not that noob-ish to forget this), and install the downloaded package. I didn't install any mods after that. Clean enough, I guess.

An update to this situation: I think that using a factory image I might be able to "clear" the partitions and hoprfully revive my storage, but when I tried to back up all my contents in storage to PC using MTP connection, it got stuck at "calculating time needed for copying files" or sth like that. I have ~3GB of (unsynced, of course - I'm in China) music and some precious data I don't wanna lose, and at this size I couldn't back them up on the clouds. What to do now?
