Retrieving data from locked device - Samsung Galaxy S9+ Questions & Answers

My brother passed recently. I am in possession of his s9+ and want to either remove the lock screen PIN (preferable) or just retrieve the pictures (if all else fails). This is very important to me. It is a Verizon phone.

If the images are stored on an SD card and the card is not encrypted you can just take the SD card out and use it from a computer.
If the phone was configured to backup photos to samsung cloud you can try logging into that using the appropriate credentials. The URL for samsung cloud login is https://support.samsungcloud.com/#/login
If the images are stored on the internal storage you are most likely gonna have too contact samsung for help. I honestly don't know if there is a way to do this considering the phone is unrootable and what your asking is to break/remove the phone's security features.

In case it has twrp installed ,you can use it

The G965U and G965U1 are unrootable at the moment... So any options for the OP that involve rooting the phone is not going to do much good

Recover file from G965U1
I have a G965U1 from which I want to recover a deleted video. I don't care if I brick the phone. I simply want the video. I'm tempted to rip open the phone, pull the memory and solder on a USB reader. Can you give me any good options prior to the rip.

Best suggestion (not just to you, this is in general for everyone who has this issue) is that in the future if there is a file you want to keep or is of great value to you make a backup of it elsewhere. I do this with what pics/videos I take on my phone for this very reason. There isn't a reason why no one can't make a backup of an important pic/video with this phone... It has a removable SD card, you can transfer files to a computer or use cloud backup.
Other suggestions:
Did you check the gallery trash to see if it is in there? When you delete a file using Gallery it ends up in the "trash" (essentially acts like the recycle bin on windows). In the gallery app look for the 3 dots that run vertically at the top right corner. Pressing on those will show a menu, the word "trash" will be listed.
Pressing the option to access the trash will show you what is able to be restored on the phone. Files you delete will be sent to the trash and remain there until you empty the trash or 15 days pass since the deletion. If you have the phone backing up the files to Samsung cloud you might be able to access the file(s) from the cloud using the link I posted previously.
If the gallery and cloud storage don't help:
I am afraid there really is no other good option.. The software I can find which does data recovery requires root access (which we can not do). Google searches pretty much yield the same result. There are some that say you can without root, but further reading into them show it's a misleading statement and that root is still needed. You may be able to find a software recovery service locally that might be able to do what you want... And I would suggest (unless you have the tools, software and ability) you go that route first before you try to CSI cyber your way to accessing that data. Please don't take this the wrong way, I do not believe what your thinking of doing will even work... Assuming the location where the video was has not been overwritten by data already (if it was then your SOL unfortunately), removing the memory and placing it onto a USB reader will most likely not resolve/remove any permission based issues.
This is a drawback of not having root ability on our phone

While this is older topic and probably it doesn't really matter anymore, i might add something. First of all, those phones are factory encrypted. Second, ability to recover deleted files from modern phones in nonexistent in practice. You may find that there was such file but it's already empty inside or not find any leftover that it was even there. You don't have to fully overwrite the space it occupied like on SD cards or HDDs for this to happen. There are mechanisms, like TRIM that take care of deleted content to maintain storage chip performance. It is possible to recover deleted data stored inside database files, like contacts, texts, chats, notes etc.
In general, there's no harm in trying but this requires you to create a decrypted memory chip dump and this either requires root or some fancy exploit, for example to boot custom kernel image with adb and root permissions that won't tamper with data. Achieving root on those devices without factory reset is not really possible for the time being, and enabling OEM unlocking (requires for TWRP and Magisk) itself triggers factory reset (there's a warning so that's good).
Desoldering memory chip and dumping it directly also won't work. First of all due to factory encryption, so no there won't be any useful data and it can't be decrypted outside that specific phone. Second, it's an UFS type memory and this requires expensive reader. The cheapest on the market is currently easy-jtag plus with adapters for UFS, but this still ~$1000 and i'm not sure it supports chips used in S9+.

[Q] Is there a way to recover deleted files?

Just realized I accidentally deleted a picture from the SD card on my Hero awhile ago. The card is quite big and has never been close to being full so I'm wondering if there is a deleted folder on the card or some way to recover the file?
As far as I know, only recovery programs as used by the police, government etc can recover deleted files. You can download loads off the internet, but they are designed to reconstruct the magnetic residue on hard discs, don't know if it will work on a flash drive. Won't hurt to try though.

This person doesnt appear to know what they are talking about, no offense.
Data recovery is possible (in theory) on all types of media. When a file is deleted, the space it occupied is marked as unused by the system. The file isn't actually "deleted" until something else has written over its space.
however, due to the random nature of writes to the disk, and given that you said "while" I presume there will have been many writes to the disk since, the chances of recovering the file fully are reduced.
recovery software: a good free one is http://www.piriform.com/recuva
http://www.easeus.com/datarecoverywizard/free-data-recovery-software.htm
Is a good piece commercial software, but the free 1gb trial should be enough to give it a try.
"reconstructing magnetic residue" is what "professional" data recovery companies might attempt I guess. sounds a little fishy to me though.
So you say I don't know what im talking about with recovery programs and the like, then point the op to 2 recovery programs. Recovery programs which, no doubt, will try to reconstruct the files from the left over magnetism of the old file.
Incidentally, I know when a file is "deleted" the memory sectors are merely market as unused, so new data can be written there, but still the only way of recovering them files is with a recovery program.
use "testdisk"
http://www.cgsecurity.org/wiki/TestDisk
Actually there is no such folder exist on card which kept the deleted files or etc but don't worry just try a good third party data recovery software for the recovery of your data and files. Try Kernel for FAT and NTFS data recovery software for the recovery of your files.

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.

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.

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...

Photo recovery from internal storage

Hello,
I am looking for advice on recovering photos lost from internal storage. The phone is not rooted and from everything I have been reading this is necessary. I have reviewed the guide on how to root the device but my concern is it indicates data will be deleted when unlocking the bootloader and I also need to write to internal storage during the process. Does anyone have any advice on gaining root access with minimal impact on internal storage or any suggestions on how best approach this?
(Un)fortunately it's not possible, it would bring a serious security issue. Locked bootloader with encryption ensures integrity and security of data. There is no publicly known exploit which could be used to root the phone without bootloader unlocking.
Your only option is to use one of the many recovery apps, though I have no idea how successful they will be, you will need to try them. Also check your google photos web folder, your photos might be there.

Thank you for the clarification. I did try several of the recovery apps but they failed and indicated root access was required for a detailed scan which led me here. I have not been able to figure anything else out so I guess it is not possible and lesson learned to backup photos.

Sorry to hear that, but thank you for reporting back. Yeah, data backup is essential these days, you never know what will happen to your phone (or Google/cloud account for that matter), I always keep also at least one separate physical copy of important data.

PLEASE i need help this is serious and urgent

i will make it quick, my father suicided yesterday 6:30 pm yesterday, and i have the task to figure out if he left a note or something inside the phone, it is a lg g5 with 4gb of ram, it is pattern protected and i cant access the phone, i know i can delete the pattern if i do a hard reset but the data inside the phone it is extremely important for me, also i know that if this phone had installed TWRP already installed i could simply delete the files and get it running again but obviously this is not possible since is a stock phone, non modded and non rooted, any help on how i could get the pattern lock to disapear without losing data would be great
First of all, let me say that I'm really sad for what happened. Unfortunately, the only know way to overcome the phone lock is to remove the pattern lock file from recovery. As the phone is not rooted, of course you can't access the memory to delete the file, and even if you could, the stock rom encrypts by default the internal memory. The only data you may save from the phone is the data stored on the MicroSD card, if the phone has one and it was not encrypted (SD encryption is optional). That's what you can do with DIY methods. Considering the relevance of the informations that could be on the phone, it might be worth looking for some reputable company and ask if they can disassemble the phone and extract (somehow) the data; the G5 hasn't received any safety patches since a long time, and maybe some vulnerability could be used to decrypt the data, but I wouldn't be too confident on this chance.
