Securely wiping old Android phone IMPOSSIBLE? - NO "encrypt" option - General Questions and Answers

I need to wipe two Android Phones that do not have the "encrypt" option. I am selling them very soon so this is important. One phone is running stock Gingerbread, the other is using a custom rom running ICS 4.04.
I attempted a secure wipe on the ICS phone by choosing every wipe option found in TWRP (dalvik, cache,etc), then I did 2 factory resets and flashed a NEW ROM after that. Guess what..? I used the free program "DiskDigger" on my PC and I found THOUSANDS upon THOUSANDS of recoverable files. FULL pictures, not just thumbnails; I found videos, I found zip files, I found voice recordings, I found music, and more!
There is no way in hell I can sell these phones until I know they are CLEAN of my information. What pisses me off is that with iPhone, it's as simple as pressing "Erase All Content And Settings". That takes maybe 5 minutes tops and it works on iPhone's as old as the iPhone 3GS! I thought custom flashing a new rom and wiping cache in TWRP would do the trick but NOPE.
Can anyone help me?

I have an idea:
Just keep copying some random worthless files over and over till your memory fulls up
then do your erase and reset, check again with your DiskDigger again th make sure only the worthless files are retrievable instead of your personal.

Is this really my only option? If so, that is sad and scary at same time, because results are still not guaranteed.
For comparison's sake, I ran Recuva which found 1,243 files. It found A LOT less, so I am glad I tried DiskDigger first. Still, Recuva showed a lot of pictures, and even if they were recoverable, you can see the FULL picture in the preview window!

Look, when erase a file from your memory it dose not actually erase it, it just hide it from gallery or file explorer and mark it on memory allocation table to be overwritten when copy other file. So your best option is to overwrite with another worthless files. Just give it a try, you wont lose any thing.
I think you might also use any safe erase application or disk utility while connecting your phone as a USB memory. Google it.

I know that flash memory is different from magnetic drives. I say it's not guaranteed because who knows how many files I have to copy over and over to replace the old stuff.
What I need is a proper sanitizing app like DBAN, but for Android. I am going to check Google Play tomorrow and see if I can find one that still works on Gingerbread and ICS. I have checked these kinds of apps in the past and they were all garbage; I could still recover files easily.

An update for you... I downloaded these two apps and ran them on both phones. Here are the results...
https://play.google.com/store/apps/details?id=com.pinellascodeworks.securewipe&hl=en - Secure Wipe
https://play.google.com/store/apps/details?id=com.aiuspaktyn.secureeraser&hl=en - Secure Eraser
On the stock Gingerbread phone, 3 photos were found by DiskDigger and I was able to preview them and recover them. Recuva found 20 files, the same 3 pictures, plus some overwritten garbage. I ran both apps AGAIN and got the same results, those same 3 photos were still there, intact. So what I then did was click on the photos in Recuva and selected "Secure Overwrite Checked". I ran the scans a THIRD time, Recuva first. It found 15 different files, 11 ignored all labelled as "unrecoverable" or "very poor". Only one photo was from before was found, but there was no preview. I recovered it, but no photo program could open it, so it looks to be successfully overwritten and corrupted.
On the phone running custom ROM ICS: I ran DiskDigger and it found 0 files; Recuva found 3 files after secure wiping. One was in "poor state" and two were in "excellent" state - a .bin file and .M file. I overwrote these files in Recuva and ran the scans a second time. DiskDigger found nothing, Recuva found 3, 14 ignored, all were "unrecoverable".
So I have some peace of mind now. Before running these Secure erase programs, DiskDigger found 99% of the contents on the phone that was running custom ROM ICS. So wiping dalvik cache, other cache, multiple factory resets, and flashing a new ROM did NOTHING!
If anyone has suggestions on other recovery programs, I will do a third check to put my mind at ease.

Wow... very surprised that there is no discussion on this. Do people not care about about the security of their devices?

[Q] Lost my WP7 restore files. Please help

Hi,
I just had to format my hard drive and thus lost all my WP7 restore files.
Is there anyway to recover all those file so that I can perform a restore on my phone?
I've tried different data restore softwares, but the files are all messed up and I can't remember which folder to put the files in.
Please help me. Thank you.
That really sucks, but this does raise a pretty good question. Where do the phone restore files save to? And how can somebody make sure their backup is going to transfer to a new HDD?
On Win7, try this:
\AppData\Local\Microsoft\Windows Phone Update\XXX-XXX-XXX\Data
I found 5.8Gb of data in this directory following my upgrade to 7390. This helps explain why the update took nearly an hour to complete...
FWIW, i've moved the data off my pc to another drive and everything functions well. The Zune update page no longers shows the option to restore to the previous update, 7008. Other than that, it all looks normal.

Thanks. Can you show me the files and folders contained in that backup?
I wanna try my luck again with this
yea, the other guys are right, I had the same issue but if you follow this you will guarantee that you will find your files
Thanks. But what I need to know is the folders to put my recovered files to
In my case it seems they're here:
C:\Users\your user name here\AppData\Local\Microsoft\Windows Phone Update\xxxxx - xxxxx - xxxxxx - xxxxx\RestorePoint\xxxx-xxxxx-xxxxxx-xxxxx\Data
I hope it helps
If you formatted your Hard Drive after you made your backup, you might be SOL unless you have a backup of your hard drive after you backed up your phone.
If you dont, The only real way is to find a rom for your phone.
The folder would be in...
%LocalAppData%\Microsoft\Windows Phone Update

Unusual recovery question

I know, I'm stupid for not ensuring I had a good backup, but it's done, I'm dealing with it.
But, I'm trying to find out if there's anything I can do to recover a file. It's a database file for an app called Time Tracker. It's a .db file.
I thought i prepared for a phone wipe to install a new rom. I did a backup to Google Drive from the program, like I've done a dozen other times. Only this time, it didn't actually back up the .db file. So, not verifying it, I went ahead and formatted the phone, complete wipe, even internal sd.
I've been looking all day trying to find a way to recover the file, so far nothing works. All recovery methods I've found only work for specific types of files like pictures, videos, office files, etc. I downloaded a couple of them and tried but like I said, they only work for specific files and .db isn't one of them.
I'm still using the phone because I have no choice, but I haven't installed anything else.
Is there any hope of recovering or am I SOL?
Oh, yes, next time I will do multiple backups and I'm looking at automated online backup for the future.

Easy way to keep one's personal data when flasing a new ROM

Most of the time when one flashes a new ROM one has to do a data wipe (factory reset), and it erases all one's personal files like movies, music, pictures etc, quite annoying to say the least.
I found a way to avoid this, and it's pretty simple:
1-in CWM go to mount,
2-mount both data and system,
3-format them both.
This will perform the factory reset without erasing our precious files (the installed apks will be gone though, but no biggie if you backed up them with Titanium).
Then you can wipe cache + dalvik and flash your new ROM.
I used this method to go from ICS to CM 10.1, from CM 10.1 to Paranoid Android, and finally back to ICS, without loosing a single kb of my files.
Edit:
I have a p6210, no idea whether it works on other models or not. I guess it does but who knows...
Give it a try if you feel like it, but don't forget to make a back up before in case it goes wrong.
After flashing, your files won't be in the mnt/sdcard anymore but in a newly created folder in mnt/sdcard/0, or, depending the rom you are using, in storage/sdcard/0.
Or, some roms may create a file called legacy and stock everything there, or sometimes your files may be stocked before the sdcard folder, search for either /0 or /legacy.
Use a root browser and have a look, your files are still in your device (have a look as well at your storage in general settings, it will show how many gbs are in your tab).
Once you have found your files all what you have to do is to move them back where they belong, ie the /sdcard folder, it takes 10 seconds.

Not cool man.Fu** lah.I lost everything.Around 7 GB of files.Fu** lah.I have no backup.I thought it would work.I was going from cm10.1 to cm10.What am I going to do?
Re: Easy way to keep one's personal data after flasing a new ROM
ALWAYS create a backup before erasing/flashing ANYTHING!! It's always as a precaution, to avoid losing something that you don't want to. And it only takes like 5 seconds literally. I lost some stuff when I unlocked the bootloader on my nexus10 by factory resetting, and I must say I didn't have a smile on my face. But it happened, u live n learn. I'm afraid if u wiped without making a nandroid backup your probably out of luck. Unless your skilled in using forensics techniques to try to recover it. Can't think of any options tho.

What did you do?
Did you follow the exact procedure?
I flashed again some roms today and it worked again.
But one thing is that the files are not in the mnt/sdcard anymore but in a newly created folder in mnt/sdcard/0, or, depending the rom you are using, in storage/sdcard/0.
Or, some roms may create a file called legacy and stock everything there, or sometimes your files may be stocked before the sdcard folder, search for either /0 or /legacy.

Once you have found your files all what you have to do is to move them back where they belong, ie the /sdcard folder, it takes 10 seconds.
This said, meishkov is right, one should allways have a back up in case anything goes wrong, I should have mentioned it in the OP but I forgot, my bad...
Edit:
OP edited.
Oh well, noone tried?
Would be nice to hear some reports...
Balaram, it would be fair from you to detail a bit what happened and to tell if you found back your files.
Anyway, this method worked for me and I thought that it might have interested some people here, roms flashers and devs alike, but if that s not the case then no worries.
If someone feels that I should erase the whole thread just tell me and I ll do it...

Recovering data from opo after deleting /storage folder and factory reset

Hi,
tl;dr:
Is there a theoretic way to recover data from the phone after:
1. deleting /storage folder
2. and then rooting (which means factory reset?)
If there is a theoretic way to recover it from the bits, is there a way to take a snapshot of the current state of the bit, so I can (in theory) recover the media in the future?
Long version:
First of all I know I'm very stupid..
Yesterday I've deleted my /storage folder since in first glance it looked empty.
Then I figured out what did I do, so I tried to recover the information.
I've searched the web for an application that does that and I found one that required rooting the phone, so I rooted the phone which means I made factory reset.
Then I tried to recover but it didn't manage to recover the photos and videos.. (it did recover whatsapp photos and some other things but not from the dcim folder).
I tried then several different applications that may not ask for rooting the phone so maybe I made a mistake by doing that (not sure that they wouldn't request for rooting either) but no success with that...
I'm willing to pay money to save that data but do you think it's not recoverable anymore?
I also called the 3 biggest recovery companies in my country, 2 of them told me that they don't think it's possible and one agreed to take it to their labs for a small price and then give me an offer.
If there is a theoretic way to recover it from the bits, is there a way to take a snapshot of the current state of the bit, so I can (in theory) recover the media in the future?
I'm very desperate and would be very thankful for your help

After few weeks of working on that, I didn't make it to recover any of my photos/videos/whatsapp chat history (the things that were most important to me)
I tried several stuff, apperently all of the recovery programs that using the adb to directly connect to the phone through the PC doesn't work well enough, as well as the programs that works from the device...
I tried this article:
http://www.dflund.se/~jokke/androidfilerecovery/
but it didn't work for some reason...
Then I tried that one :
http://forum.xda-developers.com/gal...de-internal-memory-data-recovery-yes-t1994705
I used a centos VM to get a image of the device partiotns the way they suggested (I couldn't make the busybox work).
I mapped that file as hard disk
I tried to use 'Recuva' it seems like it managed to restore files but something apperantly went wrong and the files wasn't helpful...
I tried to use 'easeus data recovery' it worked better, it found around 20k files.. There were alot of directories and I didn't look up at it so much but it recoverd alot of photos which I think were from the whatsapp media.
Incase someone who made the same mistake by deleting the 'storage' folder, get to this post, I recommend to turn off the phone immidietly and find a way to do that without rooting the device.. (although it might be impossible since as far as I know all of the methods I used were depends on a rooted device, but I didn't look up on this since the first thing I done is to root my device - which might be the mistake)...

Android data recovery - Root required or no?

Hey guys,
I have a query on recovering data from Android phone's internal storage.
The phone is J7 Pro (SM-J730GM) and I am trying to recover some deleted data from the phone.
I have tried UltData for Android but it only lists the data that is already present on the phone...it does not show the deleted data.
I tried DroidKit and it clearly states that 'Root required for Deep Scan'. Only quick scan available which is same as UltData (lists only data that is already present).
I did some research and it seems that without root, it is not possible to recover lost/deleted data.
I was wondering if anyone here has some knowledge/experience about this topic?
Is there any reliable tool out there that can recover data WITHOUT root? Or using commands via ADB shell ?
Root is the last thing I want to go for as it may sometimes brick the device.

First of all, unlocking the bootloader will erase all data of your internal storage.
To recover deleted files you investigate your storage to find file signatures.
When deleting a file only the corresponding entry in the partition table will be erased. But the data of your file itself remains physically on your storage until it gets overwritten.
Best practice for that is to create an image file of your entire storage. But at least you will need full access to your data partition '/userdata'. That requires an unlocked bootloader to install a custom recovery like TWRP and/or root. Both give you full access to /userdata at all levels, increasing your chances of successfully recovering your files.
Factory reset: Files that have been deleted by a factory reset are due to encryption of internal storage (file based) almost unrecoverable. Wiping all data also deletes the decryption key stored in the system. During the next boot process /userdata (which is empty) gets encrypted again but with different keys.
It's not mandatory to have root permissions but you must have an unlocked bootloader.
An USB connection to your PC is not suitable to recover deleted files. Both, ADB and storage access, won't open your file system directly. There's at least one system service on your phone that manages the data transfer, e.g. MTP.

Thanks for the detail info!
When I go to Developer options -> OEM unlocking, it says here "Bootloader already unlocked." So it's a good thing for proceeding further I suppose.
For TWRP installation, I checked the method but it says 'unlocking bootloader will Wipe Data.
Does installing TWRP automatically attempts to unlock bootloader (and hence the risk of wipe data?)
Here is the blog that list steps to root with TWRP and gives a bright red warning -

Easy tutorial to Root Samsung Galaxy J7 Pro SM-J730GM in easy steps. For rooting, you have to flash TWRP Recovery first through the guide.
www.androidweblog.com
So my q. is -
If I just install TWRP, does it pose a risk to automatically wipe data?
Any options in TWRP itself to recover deleted data?
The other way is to root the device using Magisk app which does not require TWRP, but a bit complicated process.
This is the blog I came across to root J7 Pro without TWRP -

Hope TWRP method does not Wipe Data & rooting method does not brick the device.
Even if we follow all the steps properly, there is always a little chance that it may brick the device

Interesting.
I also tried mounting the phone internal storage as a 'disk drive' (with letter) using a tool called MTPdrive but then no data recovery software recognizes it as a 'valid' partition. It says invalid.

If your bootloader is already unlocked, it is very good news for you. TWRP doesn't unlock bootloader or wipe your data.
mru007 said:

No.
Follow the steps properly with the correct files to root your device.
Once successfully rooted, install a good data recovery app and try to recover your lost files.
Important thing to remember is that the more files you copy or install (i.e. the more changes you make to your file system), the lesser chance there will be to recover data because the system tries to use the space occupied by deleted data to write new files to it.
So do one thing at a time and make as little changes as possible to root your phone and install the data recovery app. Do your research first to find out the best options.
All the best!

No, but you could do the following when TWRP runs:
1. Download the ADB/Fastboot tools here.
2. Extract the downloaded ZIP to C:\ and open the new created folder C:\platform-tools. You should see single files like adb.exe or fastboot.exe
3. In the address bar of your Explorer windows type cmd and hit Enter.
4. Connect the phone in TWRP mode via USB to your desktop PC and execute
Code:
adb devices
which should give you a output like this:
Code:
C:\platform-tools>adb devices
* daemon not running; starting now at tcp:5037
* daemon started successfully
List of devices attached
<SERIAL_NO> recovery
If any errors then tell us!
5. Execute
Code:
adb pull /dev/block/by-name/userdata
This pulls an image of your data partition right into the current folder C:\platform-tools.
But be aware!! The data image is as big as your total internal storage!
So, make sure there is enough free space on your storage.
If you successfully pulled the image, then I will explain you how to rescue the deleted data on it.
Even if you can recover files... the file and folder structure is lost forever. Jpegs will have no exif data, no time stamp etc. It will be a real mess.
The most you can do then is search for file type, for example jpegs. A sea of juxtaposed jpegs; every bloody jpeg on the drive.
You learned a valuable lesson on how fragile digital data can be, the hard way. Why didn't you use a SD card as the data drive? All critical data should be redundantly backup at least twice in addition to the SD card.

I learnt my lesson the hard way in 2013 or 2014, but I was eventually lucky after spending 2 sleepless nights. Lost all files on my laptop hard disc by passing a command that I didn't fully understand. After 2 days and 2 nights which looked like eternal, and trying a dozen data recovery softwares that did nothing, I eventually found one that, in hindsight, was Godsend. That software actually recovered almost every single file and was also free back then. It was then that I created a backup plan for myself and it has worked well so far.
But you missed talking about cloud backups. They are actually much more secure since they are managed professionally, although they come with some privacy concerns.

I never use cloud except for Gmail and text messages backups. Otherwise it's backed up at least 3-6 times on different drives, in different locations including time staggered copies. I may lose some data but never all...

That's one reason why you stick with the N10+ which is the last Samsung flagship with an external SD card. Since this feature isn't coming back on future flagships, you'll either have to settle with a budget device going forward, or get the 1 TB variants of Flagships, if you want access to your entire camera roll all the time.
In either case, you'll eventually run out of storage and may have to setup your own personal cloud server, if you have the required expertise to keep it safe for online access.
Cloud is not just about backups. It is also about having access to files all the time on multiple devices.

Samsung. If they can't put out they will be kicked out. Another manufacturer will pick up the slack. Both Samsung and Gookill Android are a mess now; I will continue to use what fullfills my mission for the next 3+ years. No hurry here.
Currently I'm using about 510 gb of my 1tb capacity, plenty of room left. I also have 350/100gb available on internal.
With cloud you're at the mercy of your internet connection/bandwidth, always. It wastes battery and they will charge you for the "privilege" of high capacity storage.
Multiple more layers to cloud introduce new failure modes and vulnerabilities, KISS.
Lol, do you still trust Samsung servers?
In the future you will own nothing and be happy. Not me.

Internet today is cheap and convenience has a price. So it is okay.

They have multiple redundancies built-in and I am positive they have systems in place to prevent catastrophe. I do use multiple cloud providers though, just in case.

I don't have the expertise to keep a personal cloud server safe online.

I have local backups too. It's not like I'm completely dependent on them. The local backups are just backups, and I cannot access them online.

If you had an SD card* you don't need to have internet access at all to do a full reload, anytime, anywhere. If you phone OS crashes the data on the SD card usually remains intact as well as in most hard display smashing drops.
A dual drive device trumps a single drive device every time.
*A OTG flashstick can be used but they are much slower. Backups can't be done in real time and one more critical piece of hardware to lose.

You're focussing only on backups.
I'm also looking at multi-device access to all files. This is possible only with cloud, whether 3rd party or personally hosted one.

Exactly. Android is the only internet portal I use.
My other Android only shares cloud Gmail and texting for security. My laptop internet/wifi access is always offline; completely physically firewalled. You might hack one device but never all three. All backup drives are always physically/electronically separate from the PC unless being used for backup. In the case of malware none of the backups are connected until the victim device is clean.
I've seen a Gmail account get hacked and become unrecoverable. Never had that happen to a backup hdd... in the end the only protection you have is sound data management. If you fail to do this you may lose your whole database.

This is a very special use case. For most people, multi-device access is pretty common.

As in all emails got permanently deleted? And Google couldn't help?
