[Nexus 7 Q&A, Help & Troubleshooting] bftb0:
As to recovery of lost files your options are not good. (And if we're talking a non-rooted device, the odds are approximately equal to 0%) Recovery in ext4 filesystems is technically much more challenging than in simple filesystems such as FAT. And this pessimistic outlook presumes that the filesystem is healthy/clean. If the reason for the problem occurring in the first place was a corrupted filesystem, then the odds go from simply bad to pathetically poor.

Sorry, dude... got any Nandroid or TiBu backups stored on your PC?

If you had Putin's top-secret files on your N7 and the CIA got hold of it, the first thing a forensic analyst would do is try to take a raw (block) device dump off of the "cold" device. (If you are still running the N7 with the regular OS the /data partition is being continually written to, and this further reduces the chances of file recovery every second the device is booted).

In the case of an analyst with less resources, this might mean using a custom recovery boot to get the raw device copy; unfortunately, the /data partition is huge - nearly 30 GB - so you would have to mount a extN filesystem via OTG... and doing so thus precludes using adb, so you would need to use a recovery with a touch interface and command-line entry (e.g. TWRP)

# mkdir /mnt/myOTGdisk

# mount -t ext2 -o rw /dev/sda1 /mnt/myOTGdisk/

# dd bs=8196 if=/dev/block/platform/sdhci-tegra.3/by-name/UDA of=/mnt/myOTGdisk/userdata.img

Doing such a thing would allow you to examine that huge image file with forensic file recovery tools from a PC (probably running Linux) as in principle you captured the entire ext4 filesystem.

The thing is, efforts spent in file recovery should be proportional to the value of the files being recovered. I'm not sure if your saved gaming history rises to that occasion. For sure the dude at the CIA won't want to help you with that.

As to the source of your troubles, it's hard to say. With TWRP booted, you can run the "e2fsck" program to see if the /data ext4 filesystem is corrupted, e.g.

# mount | grep /data ( see which mmcblk0 partition is /data, on grouper it is mmcblk0p9 )

# umount /sdcard

# umount /data

# e2fsck -f -n /dev/block/platform/sdhci-tegra.3/by-name/UDA

(For the last command above, you might need to use the block device name /dev/block/mmcblk0p?? instead of the UDA symlink )

If the above command shows that you have a corrupted /data filesystem, I would re-initialize that filesystem ( "fastboot format userdata" ) - note this wipes all userdata including the psuedo-SD card.

Finally, I should point out that some type of hardware failure might have occurred somewhere in that huge 30 GB partition - if that is the case then there will be problems down the road again. If that is the case, the only way to detect this will be a write test which nearly fills that partition, followed by a filesystem sanity check as shown above.

Probably that would need to be done in the recovery rather than in the normal OS, as a nearly full /data filesystem will probably wedge the device.

Phew, I've said enough.

Good luck
[Nexus 7 Q&A, Help & Troubleshooting] GedBlake:
I never tire of reading your posts, bftb0, ("...the odds are approximately equal to 0%")...genius.

But don't the CIA have access to Cray, 'Kasparov' DeepBlue beating SuperComputers that could make mincemeat out of the kind of thing your alluding to... in less time than it takes to flash a ROM... or have I been watching too many James Bond movies?

Vaguely rhetorical question - think I already know the answer...

Still... what a great post.

Hi, leont1280...

You could try running this ...

Disk Usage -

http://play.google.com/store/apps/details?id=com.google.android.diskusage&hl=en

It gives a graphical 'map' or overview of your storage, and you can visually see where everything is (or should be), great for tracking down missing stuff... but as bftb0 has mentioned, it doesn't look promising.

Rgrds,

Use astro file manager u can check it out
[Nexus 7 Q&A, Help & Troubleshooting] leont1280:
Right bftb0 i did what you said in twrp and i recieved the following summary information.

/dev/block/mmcblk0p10: 28133/1835008 files (3.2% non-contiguous) , 1571673/733977

Any idea on what that means?

Also under the mount option in Twrp i can Unmount and mount the System, Data and its Cache. However i cant Mount the SD Card. Should that be a concern?
[Nexus 7 Q&A, Help & Troubleshooting] bftb0:
Hmmm, mmcblk0p10 - you must have a tilapia (3G N7) device, yes?

If you had any filesystem errors, that e2fsck run would have produced copious reams of output. If a filesystem is clean, it produces only 5 or 6 lines of summary output.

I've seen the same business with TWRP and the /sdcard mount - I wouldn't worry about it. (It is not a "normal" mount in the sense of extN or FAT device partition mount - it behaves sort of like a strange symlink where the target directory and descendants all appear to have different file ownership and permissions than what exist in the true (underlying) filesystem. No doubt this is all performed in the kernel... I don't know whether a command-line invocation of "mount" can create this mount point, or whether a specific syscall/ ioctl is needed)

But back to your N7 - the lack of any errors in the filesystem check is good news, but also suggests that your files didn't disappear through a hardware failure. Are you sure you didn't fat-finger things when using the file manager? (I suppose it is possible that the file manager has a bug...)

I didn't look into what tools are available for extN forensic/recovery work. I can guess that the effort would be non-trivial, though.
[Nexus 7 Q&A, Help & Troubleshooting] leont1280:
Im pretty sure i didnt accidently delete it myself. When i was doing file management i was using my laptop with the N7 3g connected to it via MTP. Once i deleted the iso file the N7 started acting strange. I did notice a bit of lag that was usually out lf the ordinary and when i checked available space left it increased to 25gb rather than saying 13gb
[Nexus 7 Q&A, Help & Troubleshooting] hamid_valad:
aaah, having the same problem here, i was cleaning my n7 using my laptop, found a strange folder on my sd card, looked inside and it has a back up of some of my deleted files! interesting! i deleted the folder, then i started cheking other folders, like my ebooks, audio books and etc, but all my folders were empty!

so i disconnected my tablet, and after reconnecting, bam, all files gone. :(

Made this in photoshop today and thought I would share with everyone. Nothing special, but I made the phones to scale to show a little comparison between the s3, s4, note 2, and the possible note 3 sizes that have rumored. I shrunk the bezel slightly on the note 3 to sorta match the way the s4 did but I did not spend too long trying to perfect it so don't criticize it :)

PS- the blue lines on the screen were to make the phones to scale. And the screen sizes are...

4.8, 5.0, 5.5, 5.9, and 6.3 inches diagonally.

So if I want to add apps like the note2 gallery to my port do I just put it in the app file zip it up and sign it?
[Vibrant Q&A, Help & Troubleshooting] N00B_IN_N33D:
Hey skinzy98, real quick, just wanted to let you know that your work in the development sub-forum is greatly appreciated. Keep up the good work! :thumbup:

Now to answer your question. If you're planning to inject an app into a ROM, then you can accomplish this by placing the .apk into the system/app directory inside your ROMNAME.zip, and that's it (assuming the ROM sets recursive permissions to the entire system/app directory). This would result in your injected app being installed as a system app. However, if you want it to be installed as a data app... Well, it's gonna' be a little more involved. For what you plan to do, installing it as a system app would probably be best anyhow. Good luck, and let me know if you need any help/have any questions. Always glad to help a bro out when I can. :D

[MDA, XDA, 1010 Software Upgrading] maxlw:
Ever since i upgraded to ROM 4.00.10 i can't disconnect my gprs connection. It connects fine, I can even make an outgoing call during a grprs connection.

But I can't disconnect!!!

I have to turn my phone on and off...

Does anybody know where i can switch off a active gprs connection?

The reason I want to do this is because incoming calls get redirected to my voicemail while gprs is active.

Thx in advance
[MDA, XDA, 1010 Software Upgrading] valheru:
Odd. GPRS should suspend when a voice call comes in. If you are transmitting data it may redirect to voicemail.

The only way to disconnect the internet is to turn the phone off, or use SPB GPRS Monitor or something similar to manually connect/disconnect.

Which wireless carrier do you subscribe to?
[MDA, XDA, 1010 Software Upgrading] JoshB:
Actually, SpB GPRS Monitor's "Disconnect" feature doesn't seem to do the trick (for me, anyway).

However, you can just push and hold (for a few seconds) the "End" red button on your XDA. Presto - no more GPRS connection.

JoshB
[MDA, XDA, 1010 Software Upgrading] david beckham:
thats the same as to off the phone...
[MDA, XDA, 1010 Software Upgrading] GregP74:
I'd read a couple posts earlier about holding down the red button. I just tried it. Using the T-Mobile 4.00.10 and (is it 6.24? The radio stack that comes with that ROM) if GPRS is connected (you have the siglan bars and the horizontal arrows) and you hold down the red button for a couple seconds, it will drop the gprs and go back to the regular voice style signal meter.
[MDA, XDA, 1010 Software Upgrading] JoshB:
Not on the 4.00.10 ROM/6.24 RS. With this ROM and radio stack, holding the End/red button ends the GPRS connection, without turning off the phone. You can turn off the phone by tapping the connection icon in the title bar, and tapping "Turn Phone Off". Not sure how this behaved in previous ROM/radio stack versions.

Sorry for taking the thread off topic a bit - but I get this in the notes app in general with swiftkey too. It's pretty irritating, I don't know why anyone thought that smilies would be more useful than a new line??

And back on topic. I find the small apps really useful for when I need to jot down something, quick calculator etc. It's really nice. I came from a galaxy note and I never used the multi window functionality on that...
[Xperia Z Q&A, Help & Troubleshooting] Akiainavas:
I love small apps. They're the most useful little feature of Sony's firmware - i use calculator, notes and timer ( cooking ) all the time. I love how you can "minimise" them by dragging the window to either side of your phone. It's like a taste of REAL multitasking - when I'm using Barclays app and need to quickly calculate something, i don't have to switch apps, leave the one i'm working with and then go back - i'll just pop out the calculator and dismiss it when done.

As said though, it's a real shame we can use only one at a time. Maybe Sony will fix that. And we could use more of these actually.

Can any of you good devs provide a fix for the upside down front camera on voip apps? In the past it was working correctly for me but at some point it turned upside down (i think it was a kernel change OR a skype update). Since then i have trid the following WITHOUT any luck:

-Horizontal calibration

-Enabling screen orientation and trying in landscape mode

-an older version of Skype app

-Different Kernels (3.0 and 3.4)

-Different ROMs (CM9, CM10 and CM10.1) format everything from system to sd-ext in between

[Galaxy S I9000 Q&A, Help & Troubleshooting] DaBigFreak:
Exact same thing here, all CM10 ROMs are having this issue.

I have it in GoogleTalk, so a pretty built in application.

Tried these steps, still upside down front camera. Calibration does not show any indication, just sais lay on plane surface, push button. Shouldnt there appear a orientation point in the cross?

I only know that problem from older Windows programs, with the webcam.

There are two ways to fix this problem.

1. Fix it in system

2. Fix it in the app

First of all, the camera needs to run at all, so guess there is many work done, that the camera is running at all.

Then, it may depend on the devs way to fix things, normaly it should be fixed EVERYTHING in system, because fixing every app that might be installed, no way :D

So there must be some reason, that the devs choosed to let the upside down in VoIP apps be there, because the rest works, in camera apps orientation is fine. Maybe they just dont got the right line, to just change VoIP apps orientation.

So, maybe this will last for a long time though, till Samsung releases new drivers for 4.1.x haha :( Till then, devs must use what they got, guess they have the best working things found already...
