So I've had some images on my phone I would rather not have on there and I deleted them. Yet, if I download an image restore app I'm able to get them back. I want to know if I can delete them forever so they don't get discovered in the restore/recover. Or do I have to reformat my Nexus 4?
Running CM10.1.2 (not that probably matters).
Cheers
You can't make them unrecoverable. It isn't possible to run a forensic wipe on the internal memory as it contains everything that makes the phone run.

I know if you reformat multiple times it makes it more difficult for the common recovery program to retreve. Of course I don't expect a total wipe that forensic data companies can recover though...

All that a format does is delete the reference link to the files. If you then overwrite them with other data it becomes difficult for the average user to recover.

you can make it hard to recover
but it will still be recoverable
Download -file shredder- app from play store it will help to delete files permanently . It make u secure from recovery after selling ur phone

Just curious. There are lots of talk of backing up data. Is it really needed when doing a complete reset of the phone.

nah, I don't think so, unless you're gonna flash different ROMs. The reason why I did a factory reset is because I backed up all my system data with Titanium backup and no longer had any available space left. So not knowing what to delete, I just did a factory reset and after that still I found the left over traces were still taking up space, so I just reformatted both external and internal memory.

Using an ordinary file manager (don't use root explorer if you want to delete all your files manually cause if you don't know what your doing then you can possibly brick your phone) you could of deleted every single file that you don't need. Android won't allow you to delete important files when using a ordinary file manager so you won't harm your device. I've tried deleting files such as "Android Secure" and all it does is create another Android Secure folder.

No a backup isn't needed, but it is similar to having insurance on a vehicle. Just in case something happens you are covered.

Depends on what you're okay with losing and having to re-download.
Hello,
my OnePlus has been accidentally wiped after used OPO Tool Box (please see my post here).
I lost all my data.
When i reboot the phone i had to set the google account and all initial settings. Then Google downloaded all my apps and the contacts list.
Then i tried to recover all my photos and video (maybe about 1000 files) with Dr. Fone, but it didn't found any file related to the date before the wipe.
Why? Isn't this weird?

It isn't weird at all. It's standard for a factory reset to occur when unlocking a bootloader on any device, it's a security measure. The toolkit you used probably should have a warning, but you really should have done your research, this is a very well documented and well known fact.
OK, i see.
I mean it is weird that i can't recover data. We know that the files are not deleted from device, just hidden and flagged to be overwritable on new file creation.
I tried tools like Dr. Fone on Windows and photorec, extundelete, foremost on Linux, but they find only data that is now on the phone, not data that was on phone before factory reset.

If I'm not mistaken, it isn't just a wipe that occurs, it's a format, and data is much harder to recover after a drive has been formatted. Even if this isn't the case, data recovery is never 100% reliable.
When i unlock the bootloader it just reboots the phone in few seconds, so i'm quite sure it hasn't been a low level format!
So my data is still there, but i can't figure out why i cannot recover it

A format doesn't have to take a lot of time. Honestly, those four data recovery tools are finding your old data for a reason, it's gone.

Yes, I meant are not, my mistake.
I also tried to use this guide: http://dflund.se/~jokke/androidfilerecovery
But i got the same result.
Does the factory reset overwrite tables and partitions information? What does it do exactly?

It formats the data partition, the internal storage, and the caches.

Sorry if i reopen this old post but i need to figure out what is happened.
After the bootloader unlocking operation the phone rebooted itself in few seconds.
So what does exactly the format operation do on a phone memory (in less than about 1 minute)?
As you know, when you delete a file on a disk it is not deleted, but it is simply hidden and flagged as overwritable.
So how it is possible that none of recovery tools can retrieve old data from the phone?
Hi everybody,
I have made a back factory setting to handle a battery issue. Thinking have realized correctly my backup, I have done this manipulation. After I have restored my backup, I have seen that all my pictures were not on my phone (or in the DCIM folder).
I have rooted my phone and tried some recovery applications (like Jihosoft, ...) without any success.
I have explored a lot of websites and seen many comments saying that this operation is not possible.
Do you think is it possible to restore my data? If yes, Do you know an application or PC's software doing this recovery for Android
6.0.1 Marshmallow?
Thank in advance.
As far as i know once you format partition everything on it is gone and you can not retrieve enything.
Backups in recovery dont backup your data such as pictures,videos, music... they only backup your apps and respective app data.

Hi tks for you response!
I'm afraid to that, but I red that you could use your recuva PC which seems powerful if you can mont your Partition. I have
not try that yet.

It is a long shot. As you said you already restored backup which means you already wrote data on the partition.
Those data recovery programs work 100% when you delete/format partition and you try to recover deleted files before anything is written on that formated partition. In your case even if you manage to pull something out it will probably be corrupted files.

Yes, I am agree with you. My phone is used currently and I have received some new data wrote on the "old one" in my partition. My hope to retrieve these data is low now maybe null...
This is the value of using Google+, Dropbox, Amazon Prime, etc. photo syncing, etc. At least photos can be restored. Other files ... not so much.
Not sure what kind of backup YOU did but my CWM backups grab the entire /data partition, photos included.

If I could at least restore photos I would be a lucky man!
Crap. Son deleted LG G5 data off internal memory by factory resetting my phone, deleting my .amr's and some voice recorder files - evidence for an upcoming court case.
They were my only copy recordings necessary to prove essential points in a lawsuit.
Is there a guide or method to recovering the data off the internal memory of my LG G5 from the filesystem/flash? I figure I would need to mount the device to Windows or Linux and use some type of tool to read directly from the internal memory and dump that to my PC and then perform recovery methods. Even if I can only recover some of the files I would he happy.
Just happened tonight and phone is turned off until I figure out what to do.
Luckily phone internal memory was not password protected or encrypted - reading raw should work no?
Cheap freeware method or open-source preferred. Windows solution also preferred. None root of the phone option also preferred but not required.
if the phone was stock/unrooted then unless you somehow went out of your way.. the data was encrypted. all android devices that start with android 6 or higher have force encrypt enabled by default.. whether a password was set or not.
as for actually trying to recover the data... not sure. I thought the stock recovery securely erases the entire data partition and doesn't just format the space which is how people usually luck out and recover flash storage data.
if you had TWRP installed then perhaps it did not get erased securely and you have a better chance at recovery.
posts like these give hope that something could be restored.. but it might take more effort than using a simple tool: http://security.stackexchange.com/questions/12503/can-wiped-ssd-data-be-recovered
good luck!
The only thing I know of that may come close to recovering your data is: Kroll OnTrack Easy Recovery Enterprise. However... Make sure you aren't eating anything before you look at the price... You may choke on your food.
Autoprime sounds right. Unless you did twrp and removed encryption intentionally, you'll likely need to surrender your phone to a data recovery service to have any hope of those files being recovered. Unfortunately, I cannot further advise you on recovering data from your phone, especially as I'm not even sure it's possible at this point.
I know you didn't come here for a lesson, so I'll just say that if you want some tips on device security or cloud backups, feel free to contact me for advice.
Hello guys, I have a S8+ 955U version tmobile. I was on oreo beta and wanted to revert back to 7.0 latest which is G955USQS2BRB1. I odin the files but it caused me to format my internal memory. i lost all my photos of my newborn.
How can I get them back?
I've tried a few programs but I have to be rooted which I'm not.
I found a thread SAMPWNED to root device but I can't downfrade that far back.
Any help would be appreciated.
P.S. no i did not have an sd card in the phone, all files were saved on internal.
It's really difficult to recover photos from a formatted internal SD card. Best option, I think, would be try some other recovery apps, so see if they have access to your phone, though I don't think they will have that type of low-level access.
Another possibility might be to use ADB and if you can, pre-system/security startup, enable ADB within the phone, and then you might be able to do a recovery scan of the phone partitions.
There are a few (vague?) how to's on using ADB to enter the phone pre-system/security. Search 'sonnettie', the author of one method, and you will likely find other author off-shoots of the same type of method. If I don't stay current with a thing, I forget most of the details, but that was his original(?) method, which as I was told, came to be used by others to get into the phone pre-system startup/security. It might have been obviated by the Oreo update with a bug fix.
Did you have Samsung backup configured? If so it should have uploaded the photos and you would be able to restore them. If you don't make a backup your photos are already lost, you never know when your phone might die, be stolen or in this case get formatted. Google photos is a good alternative to keep your photos backing up.
Some people have incorrectly stated that it is possible to recover the photos after formatting internal storage. The data partition is encrypted by default and unless you are able to recover both, encryption key (it was most likely overwritten during first boot after factory reset) and the part of the partition containing the photos, you cannot get your photos back. Also, I have not seen any commercial data recovery software, which is capable of finding encryption keys and deciphering corrupted data partition.
Exactly, the phone is encrypted, not remotely possible to recover the photos scanning the memory

good to know.
Thanks everyone for your input. After spending countless hours trying to root phone so I could get a data recovery program on it, I gave up. Turns out I had google photos and Samsung cloud turned on and it synced all my media. I got all my media back on my phone.
Thanks guys
@OP
i want to remind you that if you are doing like updating, flashing, modifying, always make a back up thank god samsung cloud is doing that for you., but i always make a hard copy to my sd card always you newer know right. i am happy for you that you got your data back
