Data recovery after factory reset. Help please! - Android Q&A, Help & Troubleshooting

Long story short, my wife upgraded from her old android phone (HTC Sensation XL – Android 4.0.3) to a new iPhone a few weeks ago. I thought everything had been moved off it so I did a factory reset (including the checkbox to clear all data) as it was to be handed down to another family member. I then set up the phone with the new account, installed all the apps, etc.
The next day I found out there was a very important voice recording from the stock android program (.AMR format) of a work meeting she has to transcribe minutes for....
I then proceeded to try the following PC programs -
- Recuva
- EaseUS MobiSave
After more googling I decided to root the phone as some data recovery programs require that. After rooting I tried –
- Wondershare Dr Fone
- Diskdigger Pro (on phone)
- Undeleter (on phone)
- Zero assumption recovery
Some of these programs found deleted files but nothing I could see was from the original content, not even a single picture.
My last resort is trying to dump the contents of the phone to a RAW format then converting it to a VHD mountable file, as per the following guides. However this seems to be only if the data is corrupted or file deleted (not factory reset?)

http://blog.avast.com/2014/07/09/android-foreniscs-pt-2-how-we-recovered-erased-data/
I think it is possible to find a picture or two, or maybe some text messages. But the chances of a 30min audio recording being intact are basically 0% right? I am reasonably technically skilled and said I would try all options, but it seems I am fighting a losing battle...
Any comments or suggestions must appreciated!

deleted photos in the interenal storage

like the title says i deleted a whole folder of photos of my daughter by mistake. is there anyway to get them back, anyway! money no oject, they was and are very important to me i am madly saddened.
thank you adam
You can try recovery softwares on your PC like easus data recovery or such. Just plug your phone via usb. Havent tried it though but it wont hurt if you give it a try.

Try this: http://www.squidoo.com/recover-deleted-photos-from-galaxy
Or this: http://www.slideshare.net/Selena201...deleted-photospictures-from-samsung-galaxy-s3
Or: http://www.wondershare.com/data-recovery/android-data-recovery.html
Of utmost importance is that you immediatly stop using your phone until you are ready to use a tool to recover files
since any activity runs the risk of overwriting the photo data.
However I'm not sure if any of the tools really work on the S3. Reason being that the internal storage where the photos are often (but not always) located is not USB-mountable on the S3 (regardless of what some articles linked here claim, it's not true, Easy-UMS can only mount the external SDcard)
The data exchange protocol (MTP) on the S3 is not able to restore files, you'd need a tool which runs on the phone itself and has full root access. I'm not aware of any such tools, especially not working ones. This does however not mean you should give up.
You can take a backup of the EXT4 partition through dd so you can attempt to restore it on the computer while continuing to use the phone.
On a sidenote; can anyone confirm the S3 is not using TRIM on it's SSD? Since that whould effectively make any restore attempts pointless due to the data already having been physically wiped a long time ago.
I had this issue too and spoke to Samsung Directly..there is no way to do this on INTERNAL memory! external yes
I did that last week
So the solution is download undelete pro from Market and it will recover 98% of your lost photos & Videos, but keep in mind that you shouldn't use your storage meaning take photos, copy files, etc... just straight to market install the app and it will do an almost perfect job.
Hope this helps.

[Q] Questions About: Encryption + Backups

I've recently been getting into more security cautious habits with encryption and what not, due to this whole NSA/Big-brother is watching business... But I have a question (more may pop up as this discussion goes on). Sorry if I seem noob-y, I am still getting a hang of all this encryption business. But here's my first round (regarding just the files being backed up):
If I go ahead and do a full phone encryption with my GN2 where will I stand as far as backups to Dropbox/Copy/Google Drive/etc.?
I currently have photos and such backing up to copy, and I often move backups made through recovery to Dropbox and such. If I were to have photos automatically sync to copy or move system backups to dropbox wouldn't that render them basically useless as I am assuming they move out of the phone encrypted (not being decrypted as they exit).
The photos would be unusable anywhere besides my phone right? So moving them off my phone to share vacation photos for instance would be impossible, and if my phone were to crash they'd be irretrievable? Making the backup process pointless.
Wouldn't the back up be rendered useless as well, exactly when I might need said backup? If my phone were to ever crash or die for some reason, I would lose the encryption key, would even be able to do a full system restore through the recovery? It would seem that the encryption key wouldn't be kept with those back up files, so while it might place everything back in its correct place, it would still be unreadable. Or does it maybe keep the key in system files somewhere so that a full backup would restore the key as well?
And my second round of questions (regarding recoveries and what not):
I am also under the impression that I would not be able to flash through custom recovery either as the internal SD would be inaccessible from the recovery being it doesn't have the encryption key. I am currently running OmniROM and it is in a nightly stage still for my phone. I wouldn't be able to update nightly would I? I am assuming since it basically flashes/overwrites system each time, that I would be losing my encryption key and making everything besides system unusable then right?
And what about downloading ROMs to flash/update directly to my phone? As I download them from in browser or another app and they go to the default /downloads folder they would be encrypted. They wouldn't be accessible from there in recovery, but if I were to try and move them out of internal SD to the external SD they would retain encryption and still be inaccessible? So the only way to download ROMs and updates would be from PC and only move them to the external SD?
Overall, this seems to be crippling a lot of the way I use my phone...
Bump?
Sorry, this is already getting buried and I kinda want to know what's going on before I go ahead and do this...

I'm not (yet) an expert on this, but when you've encrypted your device, it encrypts the file system on your internal memory and SD card. You have to enter a PIN/password when you turn on your device (and when it times out) to gain access. When the correct PIN is entered at boot time, the file system is available as normal - the underlying data is still encrypted, but the file system can unencrypt it in "real time" for use by apps and the system.
So that means that Dropbox et al all see your files as normal, and any copying you do from your device to something on the net (Drive, Dropbox, a server, etc.) works as normal - the data appears normal to the apps and is copied as normal. So photos would copy across as photos, music as music, etc.
Think of it like this: You can't speak Urdu, only English. There is a book you own that is written in Urdu that you want to tell someone about. You find a translator to read the book and tell you what it says. He reads the first page in Urdu, translates it in his head to English, and tells you what it says. You then tell your friend what it says (in English, of course). Your friend writes down what you told him, in English, then tells you something in reply. You tell your Urdu translator what your friend said (again, in English). Your Urdu translator then translates (in his head) what you said from English to Urdu, and writes it down in the book in Urdu.
At no time do you understand Urdu, nor does your friend. Your friend doesn't even know the book is written in Urdu and doesn't care. He never sees it or accesses it directly. If anyone ever steals your book, they can't read it unless they can read Urdu. The book is only useful to you and your friends if you have an Urdu translator sitting there in the loop. (the analogy is imperfect and incomplete but you get the idea).
So, getting back to your phone, if you have it encrypted, the underlying file system deals with translating things on the fly if you've given it the correct password at boot and login time. No apps ever know about the encryption - they just see data as normal (unencrypted). So any app that wants to copy a photo to Dropbox just sees a normal photo - it never sees the underlying encrypted data. But if you don't enter the correct password at boot time, the phone can't boot, and anyone trying to access the data on the phone won't be able to read it unless they know the password.
Does that help or confuse?

Hmm, this does my head in a bit but lets untangle it:
- you boot into Recovery. The Recovery you're using (obviously) understands encrypted file systems (some versions of CWM do, some versions of TWRM don't for instance - see near the end of this post for a bit more on this). So when you boot into Recovery and enter your PIN/password, it can then read your file system. You can then do a Recovery-based backup of your file system (or individual files, though I'm not aware that you can do this). The backup it creates is written to the encrypted file system and thus encrypted with the same encryption keys used for everything else.
- You boot the phone back up as normal and enter your PIN/password, and start up Android. You then use Dropbox to copy the Recovery backup files to the cloud. So the question is, "Are these files encrypted?" and I think the answer is, "No". Why? Read the rest of this post and hopefully you'll work out the same conclusion. But I'm pretty sure that the data that ends up on the Cloud is not encrypted.
One general comment worth pointing out as an aside (sorry, this paragraph isn't really related to the above but I wanted to point this out somewhere and its still useful) is that each time you encrypt your phone, it creates a unique encryption key - even if you give it the same PIN/password to use. So if you're forced to rebuild/reflash/wipe your phone in the future, it won't be able to access any data that is still on there (in internal or SD memory) since it won't know the previous encryption key. So you'll have to wipe all data and start again. And at that point, if you choose to encrypt your fresh, newly initialized phone, it will have a new, unique encryption key that won't work on any encrypted data from previous. So if for instance, you plug in an SD card that was encrypted on your phone in an earlier ROM, it won't be readable even if you know the correct PIN/password, since your phone will be using a different underlying unique key.

So, if you're following this, you'll now understand that moving your photos off your phone could be done two ways:
- while you're using the phone as normal (ie. you've booted it, entered your PIN/password, and copying your photos to Dropbox via an app while you're logged on. If you do it this way, you're simply copying photos as normal that can be viewed as normal in Dropbox.
- by copying backups generated while in Recovery. But Recovery will be firstly mounting the encrypted file system successfully (if you gave it the right PIN/password and your version of Recovery supports encryption), which means it can read your photos as normal files, then backs them up into its own normal Recovery file/folder structure and writes them to your encrypted file system, so the underlying data is encrypted unbeknownst to Recovery. Then when you boot up your phone and log in successfully to Android, you can access that data as normal (and unencrypted). So when you then copy it to Dropbox, all you're copying is normal Recovery-created backup files. The copied data won't be encrypted (unless Recovery encrypts them itself, independently, which I don't think it does). So you could copy this data to anybody's phone, so long as they were using a compatible Recovery version and probably compatible ROM.

I'm not 100% sure on this, but I think your logic is correct. The backup would be useless if the phone loses the encryption key, which it would do if you re-initialized your phone and/or did a new encryption. So you can only recover your backed up data if you haven't done either of those things. A solution to this is to use backup software that runs on your phone (Titanium Backup) that gives you the option to encrypt your data. Some caveats to this approach should be obvious:
- you firstly need to decide if you trust your backup software's encryption
- you need to use a strong password and be able to recall it months/years from now when you go to restore your data
- you need to copy your backups off your phone (such as onto your SD card, cloud, dropbox, etc.) in case you lose your phone.

And my second round of questions (regarding recoveries and what not):
I am also under the impression that I would not be able to flash through custom recovery either as the internal SD would be inaccessible from the recovery being it doesn't have the encryption key.

Tricky - if you flash/update your phone with a new ROM, you will probably be OK so long as you haven't wiped the part of your phone's storage that holds the encryption information. I don't know where this is. But the nightly updates I do to my phone don't normally touch my data - all my apps are still there and it boots identically to the way it did before I updated it. HOWEVER, its possible that an update may force me to wipe my phone for some reason - the update may fail, it may contain significant changes, or I might screw something up. I probably end up completely wiping my phone at least once every 2 months just because I like to play with the latest and greatest ROMs, or I screw something up. So if that happens, I'm going to lose the encryption information and thus would lose everything on the phone.
Of course, I can always restore my apps and data via Titanium Backup, since I back up my stuff quite often and then copy it to Dropbox.
Zombtastic said:

Hmmm - good question. A simpler question is, "Is my encrypted file system accessible while in Recovery?" I believe the answer is, "Yes, if you use CWM, No if you use TWRM". But I say that because from what I've been reading, some versions of CWM/TWRM can/can't handle encrypted devices. But you'll already have sorted this out at the time you're trying to encrypt your device anyway since the encryption process involves rebooting your phone into recovery I believe - and if you're not using the correct supported Recovery, this step will fail. But if you are using a supported recovery, this step will work, and therefore logically I'd assume that you can access your encrypted file system while in Recovery in the future. I'd imagine Recovery would prompt you for your PIN/password in order to mount the encrypted file system.
So assuming the above is correct, you would be able to access the newly-downloaded ROMs while in Recovery and thus can flash them. But of course, Caveat Emptor with flashing the new ROM - if it forces you to wipe anything, you may end up unable to access any of the data.

From what I've been researching, you won't have a problem anyway, because I haven't come across anyone that has successfully encrypted their phone using a custom ROM. Strangely, this ability seems to be unwanted by XDA people. My tinfoil hat tells me that there are people ensuring that this ability continues to not work on custom ROMs until/unless a backdoor capability is found. Hopefully I'm wrong on many counts.

Amazing post by the way! It does seem very helpful.
BUT it's very funny you mention it not working. Because that's exactly what happened. After not getting a response here or in the ROM's forum for a few days, I decided to just take the plunge and do it. I was just planning on testing everything out my self and figuring it out as I went. The first time it seemed fine, the encryption went through it seemed.
Being as I didn't know any of the info you just enlightened me with, I did fear that nothing was truly encrypted though. Everything was transferring to my computer with a drag and drop and working fine, so I was afraid (without evidence) that nothing was truly encrypted. I asked on the ROM's forum again (still waiting for an answer).
That night, my phone was left plugged in charging, yet some how had turned off in the night. I awake to my phone asking for an encryption key. I enter my key in to no avail. Nothing works and my phone is left unable to boot. It was utterly denying my password. I had to reflash. I asked about that in the forums as well, whether that was normal or if encryption was maybe not implemented yet, etc. The dev running the nightlies for my device has responded to the forum multiple times but not to me. Another user mentioned it might be that it is now merged together as a Galaxy Note 2 ROM and not specifically a T-mobile Galaxy Note 2 ROM (might be possible. Idk.).
Now, I have tried to re-encrypt. Multiple times. But I cannot for the life of me get it to even start now. Every time I go to start the encryption process it shows me the fullscreen image of the android unzipped horizontally (at which point it is supposed to reboot and start encrypting) and it hangs/sits there forever. Not rebooting, not anything. If I hit the back button, the image disappears and it goes back to my phone. Working perfectly fine, like it never even started doing anything. I am not doing anything differently. I don't know what could be happening to stop it from even getting as far as it did last time. Unless the devs maybe started working on it and have disabled it for the time being/screwed it up worse, I dunno.
Not you got me crafting a tin-foil hat...

[Q] Any way to interrupt factory reset or recover data?

Doh!
I started a factory reset on my phone, then realised I still had unsaved precious holiday photos on the device.
I removed the battery almost instantly after pressing the reset button, thus stopping the process. The mobile is connected to a PC by USB, but of course without the battery in place there is no way of viewing and transferring files on the phone. When the battery is replaced, the factory reset process continues where it left off - on the "deleting files" screen.
So-
1. Is there any way to stop or interrupt the factory reset process?
2. Is there any way to retrieve the photos/files whilst the reset is frozen with the battery removed?
3. If the files cannot be recovered by normal operation of the phone, can they be recovered by a specialist company from the deactivated phone?
Phone is a Samsung Galaxy S3 Duos (dual-SIM) GT-i9300i
Android will be stock current version.
Thanks for any help!
Bump.
Additional question:
Whats a recommended recovery utility to try and recover files after a factory reset?
Thx
Hello buddy, so when do a factory reset in any device is impossible to stop it. You 'll lose all your files. Is very important to do back ups in many memories card or in an app (Google drive).
I auto-back up all files except photos (to stop very large files being auto-copied to other devices by Google/Dropbox, etc) and normally just transfer each batch of photos to a server archive.
On this occasion I was just looking at the factory reset options, and off it went (screen is somewhat over-sensitive on this phone) - not even a warning dialogue, as on other devices and versions.
If it can't be stopped, then my only hope is to run a retrieval programme as soon as the phone has finished rebooting. Hence my question about what is the best/most successful data retrieval application that people recommend?

I am afraid that data retrieval is impossible since you haven't made some sort of backup and have deleted everything by factory resetting. Sorry buddy.

Dont get so worried. Wiping data partition doesnt delete /data/media. Which means your photos , videos , downloads is still there. Which recovery do you use ?

Urgent: Recover deleted photos/videos from internal memory (Galaxy S6)

Dear guys,
I accidentially deleted around 70 GB of videos and photos on my Galaxy S6 128 GB (SM-G920F, Android 6.0.1, G920FXXU3DPDP). I was so stupid to try to move the camera folder instead of copying it to the computer and since the process was aborted it was gone from my phone and not on my computer. I'm missing a lot of family pictures and videos that were very very valuable for me.
My phone is rooted (odin) and the root works properly. I tried several recovery programs, some are working in general and are requesting supersuser rights (like phone paw android recovery) - but can't find any of the deleted images and videos. Others (like Wondershare Dr..Fon Android recovery) do not work properly (it gets superuser rights but in the last step before scanning the phone it tries to get (other?) super user rights that are not properly requested).
I should be gratefull for any kind of help. Please let me know if you need any additional information. It would be the biggest present to get back any of the many photos and videos I lost.
Best,
Sonstiger
Or does anybody have an idea where I could find help? The photos and videos are precious memories of my daughter and two holidays.
Thankfull for every help!
An addition: I wouldn't mind if the procedure to recover (part) of the photos / videos would break my phone.
you didn't have any back-up solution? try some photo recovery apps from play Store like: DiskDigger or DigDeep Image Recovery, i can recover almost all deleted photos but have no experience abt recover video
In the past I've had phenomenal success with Dumpster: https://play.google.com/store/apps/details?id=com.baloota.dumpster&hl=en
Of course I can't guarantee anything, as file deletion and recovery is a bit.... weird. However, with Dumpster I've been able to recover many photos on multiple occasions, even really old ones (months, maybe even a year for a few of them) I had forgotten I had deleted. I didn't even have it installed before deleting said photos either. That being said, since your photos/videos are freshly deleted, it may work out for you.
Good luck!
Thanks ubergeek77.
Unfortunately, Dumpster only recovers files that have been deleted after Dumpster has been installed. So it can't help in my case.
Any other ideas?
And there are some more promising tools for the PC. E.g. I tried Wondershare Dr.Fone for Android. It scans my phone (with superuser permission). But not a single photo / video of the ones that I deleted (70 GB) are found. What could be the problem here? Anybody out there who can help me and finds the time to reply?
Connect your phone to your Pc and try some recovery software like EaseUS..... (this is not a free software but you can install trial version).
hope it help.
Next time, if the transferring process is aborted , just undo and get back your file right from PC.
None of this tools found relevant photos or videos from the 70 GB i lost. I will now try to get an image of the data partition to recover the files on PC. Anybody can help me here?
I was now able to copy an image of the data partition on my computer -- using Photorec I could scan this partition for lost files. Unfortunately only undeleted or not relevant files were found. None of the files of the 70 GB deleted pictures and videos. But there have been tousands of files (from 4 MB each) extraced with the file extensions ".elf" and ".sqlite". I assume that these files are my lost photos and videos and that they, for any reason, cannot be assigned correctly .
This may be related to the file system ext4? Or the blocksize? Or any other reason related to the fact that these files were not deleted the standard way but while trying to move a to big folder to my PC.
What can I do here? I would be gratefull if any expert here being familiar with the ext4 filesystem or Android partititions could help me in any form. Please let me know if you need an additional information.
Looking forward to any reply. Thanks!

Very sorry! I totally misremembered what app I used. I just checked, and it was definitely DiskDigger, it works without having been installed first, and works even better with root: https://play.google.com/store/apps/details?id=com.defianttech.diskdigger
Sorry for the confusion!
The results I mentioned were with root, so that may be something to keep in mind.
Also, I'm not 100% sure if TWRP backups are 1:1, but you should research a way to make a complete raw filesystem backup of your device if DiskDigger doesn't work. The more you use this phone, the more you risk losing some of those photos. With a raw disk image, you could mount it in Linux and throw every recovery tool you can find at it.
Best of luck. If I run across anything that may help, I'll be sure to post it here.

Data loss after restart

Device is Samsung Galaxy Tab A 7.0 (2016) 4G LTE (SM-T285), running Android 5.1.1 (Lollipop), without root.
Device suddenly lost network coverage (not the first time), and flight mode did not solve it (not the first time, also), and the only way usually was to restart (power off/on).
Usually that would solve the problem.
This time, the same thing happened, and upon restarting the device, it spent a long time at the Samsung logo/splash screen (which is abnormal), and when it finally reached the lock screen, it took a while before the entire screen was loaded (wallpaper appeared first, then the time...). Upon entering into the home screen, some (not all) widgets were missing (noticeably the custom downloaded ones).
Opened the usual apps to pick up from where I left off, and those apps ran as though it was the first time (as if it was just installed). App data (that was stored on internal storage) was lost. Other data (SMS, pictures) were intact.
My immediate concern/focus right now is to recover the lost data, either by fixing this abnormality (safe mode/guest mode, maybe?), and if that fails, at least recover the lost data (preferably without requiring root).
Any ideas?

Well, I don't know if you can even recover your data.
But what I know is that the data left on your device must be saved, as you would have with the others apps.
Would advice el famoso Titanium Backup (root) :

I don't know whether the data is actually deleted or I actually stumbled onto a separate "sandbox" (something like guest mode...?) because only specifically the app data was gone (so far). Any ideas about this abnormality?
