Managed to unlock most .dm/.dcf files but... - G4 Q&A, Help & Troubleshooting

Hey!
So i managed to finally unlock most of my .dm files after checking this forum out, but i have a problem. I kind of moved some .dcf files before i could decrypt them, and as a result, now the phone gallery refuse to read them, even though the file manager shows that they do exist.
Anyone has an idea as to how i can go about unlocking said files?

[Q] File Recovery (Pictures) - MTP

Hi guys,
I really need your help on this one.
I have searched the forums and the web for a full day now and it seems that I am not alone with my problem here:
Last night I used Solid Explorer to create a subfolder with pictures within the Camera folder. I then tried to move that folder somewhere else on the "SD Card".
But when the process was finished, the subfolder was empty and all the pictures were gone. I could still see the thumbnails in the Camera folder, but when I tried to open one of them, they also all just disappeared!
Now I have read several threads here on xda about the problems of file recovery on a MTP device... Seems like normal file recovery programs will not be of any help in this case.
However I was hoping, that by now someone came up with a solution to this problem, since it affects all users of the GNex.
Some more infos on my side:
The phone runs 4.0.4, is not rooted and not unlocked - everything is stock.
Data back up via Google Plus and Dropbox was not possible, since I am on holidays in Asia with no data plan or WiFi available.
I have switched the phone to flight mode and (hopefully) not written any new data on the storage.
So my questions would be the following:
1) Has anybody yet found a way to asign a physical drive letter to the GNex, making it possible to be recognized by regular file recovery software?
Or is anybody currrently looking into that matter, trying to find a solution?
2) In case that I will not be able to recover the pictures myself through some pc software off the net, will I be able to let some professional have my files restored for me? If I understand correctly, all it takes is a software, that is able to recognize a ext3 or ext4 storage system???
I would really appreciate any help on this matter, because these pictures mean a lot to me and I really hope that I will be able to get them back somehow.
Thanks in advance,
Patrick.
Edit: Argh! First post and I got it wrong already! Sorry, I meant to post this in the Q/A section but ended up posting it in General :-/
I had to format my sd card losing 13GB of information yesterday. This was also due to stupid mtp. Sorry i doubt you can recover.
Sorry to hear that! Until now I could never understand the objections many people seemed to have concerning MTP, as it handled pretty much the same as an USB device when using a Windows PC. But now that I gained some insight in the matter, it's probably the ONE thing I don't like about this phone.
It just sucks to find that out the hard way...
But maybe somebody else still has an idea and can point me in the right direction?
I've had the same problem, and I'm blaming MTP as well. I finally gave up, formatted my drive and replaced MTP with cloud services or transferring files via adb.

[Q] Data totally wiped?

Hello everbody,
I've done a big mistake ... I've unlocked my boot loader but forgot to backup my data. Well, the config files for the few apps aren't the problem, it's more that the videos and pictures are gone now.
I've searched the forum and found this guide here. I did everything which was written down there expect that I used Linux to get my dump of the internal storage.
Well, now I'm sitting here with the dump (around 16GB) and tested tools like photorec and Recuva but nothing seems to help. The only files I'm able to see are the latest PNG and JPG Files. No older stuff which are gone due to the bootloader unlock
The bootloader unlock itself ran round about 2 or 3 minutes. Within this time (due to my technical knowledge) it's impossible to wipe or destroy the internal storage that hard that no files are found anymore. I mean if the internal storage would be filled up with zeros I would understand that, but it only has taken 2 or 3 minutes to unlock the bootloader so the zeros fill up just could never happen in my point of view.
Can anybody please me out here? I have read so much posts about the success of the people after they started the recovery immediately after this bootloader unlock wipe that I just don't get it why I just get nothing out of it ...

How to unlock *.dm files on other phones (Not LG)

Hi everyone.
A few weeks ago, I was the owner of an LG G4 Phone.
Unfortunatelly, it came with a factory problem, and now it's dead.
Now I'm using an HTC.
I had some locked files using the "Content lock" option, and send them to the SD card.
But now, on my HTC, of course I can't open them.
Does someone know how this can be done?
Maybe someone could export an apk for this, like "content lock.apk" ???
Hope there's a workarround for this.
Thanks in advance!!!
You can't do anything. The DRM keys are specific to your phone. If things are locked or encrypted and you transfer phones, there is NOTHING you can do. G4 uses hardware based encryption. Even transferring it to another G4 would be pointless.
Buuuu, OK. Thanks for the quick response.

I have the same problem with it. Mine was in the state of boot loop until it die.
Is it possible to unlock the .dm files on my sd card after I fixed my own LG G4 ?

hey, i had this problem with my LG G3 D850 AT&T and what i did was connect the phone to the pc and copying the locked files in another folder. Then i searched in my phone and the problem was solved, the files y copyed apperead and the files that were in the original folder. Srry for my english, im not a native speaker but i hope you got the idea and solve the problem as i did.
Greetings from Dominican Republic
I've hunted everywhere for a solution to this. I have over 100 photos locked through the LG G5 I had (I now have a Samsung S7) & can't find any way of unlocking them.
Please can someone point me in the direction of how this can be solved, if it can. I see Tadp0le on this thread says it's can't - is this still the case?
Thanks
I have a fix!
Ive read through a few posts who's problem seems similar to mine in that I locked files on my phone on the SD card and cant get them unlocked. I changed the SD Card and when I wanted to get the files back it was telling me it failed to unlock them and all the photos had a ".dm" attached to the file name.
To solve this I put all the files from the SD Card on my computer, connected phone with new SD card and copied over the folder into the new SD card. When I went into the image folder and selected "Show Locked files" and nothing appeared........
What I did next was select a photo already in the phone and locked it and because its a new SD card it asked me to set up the lock password and once done, it locked the photo and it disappeared. Then this time, when I chose to show the files it opened and had not only the photo i'd just added but also the folder i'd imported with all the images!
You will need an LG phone to get these files unlocked so if you've bricked your phone, either get another LG or ask a friend you can trust who has an LG
Hope this helps someone
fix

hey , i did mine just now. i got the idea from one of the post on this page
move the locked file to the computer , lock a new picture or video on your phone. Move the locked files on your computer back to the sd card, but put it in the same folder of the picture/ video you just locked.
They will all show up it locked files on your phone ( it might not show up right away though)

you re the man ! To be honest , i didnt really get what you meant, but it gave me the idea of how to do it. I fixed it thanks to you
On another LG phone, login with same google account which was logged in while locking
*.dm files are encrypted files of LG, normally photos and videos. If you have locked It in any lg device it can be unlocked by any recent lg phone logged in with same google account which was used to lock .
Suppose you have locked some photos using LG G3 & the device was logged in with [email protected]. The locked files get .dm extension. You have some how backed up those .dm files and now your LG G3 is lost/dead.
1.Lend any of your friend's LG phone (LG G2/G3/G4/G5/V10/V20)
2.login the device with [email protected]. (same google account which was logged in while locking).
3. Transfer .dm files to any folder of Sdcard and RESTART.
4. Open Gallery--> open any image--> click option(3dots)--> lock-- > set pin and backup email
(step 4 not necessary if pin already set for locking)
5. Open gallery--> Click on option(3dots) and select "show locked files"
6. YOU WILL BE ABLE TO SEE all locked files including those you want to unlock.:good:
7.Unlock files you want to unlock and now .dm extension is gone.
8.you can tranfer and be able to view those files to any device.
9. Say thanks to you friend who allowed to lend his phone anf ofcourse me too. :victory::victory::victory:
Fix addendum (cannot be unlocked from different google account then locked it)
Thank you! Thank you! Thank you!! I was finally able to retrieve some really important locked pictures.
I had one issue with the instructions below. When I added my gmail account to the phone and then followed steps 4 and 5 it still automatically associated the lock with the primary gmail account instead of the one I added (and had originally locked the photos with).
Instead do as follows
Settings->Security->content lock->(if you already set up a lock on the phone put in the password you just set up)->google account->Choose account that ORIGINALLY locked the files-> ok->set lock.
Afterwards go back to the gallery and follow the rest of the steps(4 to the end). Voila! Pictures are finally unlocked!
Thank you all again because without your fix I never would've fixed my issue.

.dm file unlock assist
Hi. to successfully unlock your photos that are classified as .dm files on other phones or your computer, try unlocking them on the phone they're stored on. From there you should have no issue viewing them on another phone or your computer when you transfer them over. I had the same issue earlier with my photos, now I'm good.
Before i root my LG G4, i take out my SD card and after proceed, i went through couple errors for rooting which was not compatible with my LG G4. After a day of frustrating because i had to setup my info like a new phone couple times but after rooting, setup info again and inserting my SD Card, i dicided to check my "SHOW LOCKED FILES" but ask for enter new pin but when i got in, my files were not displaying and when i chick, it said " LOOK TO ANOTHER GOOGLE ACCOUNT AND CANNOT BE OPENED." I knew i add back all the account i knew i had including my Google account but still my files doesn't show. I switch between both account and nothing still. hAVE LIKE 2,000 + FILES LOCK TO SOME IDK GOOGLE ACCOUNT BUT can someone can someone help me PLEASE!?????????
I lost a bunch of locked photos when my LG G4 died. On my LG G8, I want to keep these photos backed up on my PC so this doesn't happen again. Problem is, even after unlocking the photos on the LG G8, then copy them over to the PC, the files still show up as jpg.dm (again, they were unlocked before copying) and cannot be viewed on the PC when you want to see the photos on your large PC screen. Any solutions to this?
Study on Decryption of Files Encrypted by LG Gallery App
I'm sure someone with encryption knowledge, can create an app to decrypt "dm" files

In google: "popup podownload LGEID2" and download the pdf.

Any way to access temporary update don't files?

I am unable to update to any new build ATM because my memory is full of failed updates. My Temporary files for build updates is over 2gb and nothing I have tried can clear them out. I don't want to go through the trouble if rolling back or hard resetting, I just want the garbage gone!
I can't recall offhand which directory it was, but after enabling Full FileSystem Access and connecting to PC, I was able to locate were all of the temporary updates are stored. There were hundreds of folders in there with number and letter strings for names, so nothing is easily identifiable. And of course it wouldn't let me delete anything either.
Does anyone have any idea how to identify and delete these failed updates?
Hardreset.

I specifically stated i don't want to do that.. But I know, because this OS is full of holes that's probably the only solution.
Still though, there has to be away to delete the files. If we can replace in-use files like the notification icons on lock screen, we should be able to remove dead update files.
"I was able to locate were all of the temporary updates are stored."
Where?

I'll look again and let you know. I'm pretty sure I saved a print screen of it on my laptop.
You need to enable Mass Storage with WP Internals.
I would love to know where they are stored, keep us updated
Sorry for the delay.. here is the screenshot of the directory i mentioned.

Delete all in this directory? This is needless files?
In the Downloads folder i believe, yes. However they can't simply be deleted, it does not allow it. I'm taking an educated guess that this is where the update files are stored, as it's a similar directly to where the PC stores Windows Updates.
ive managed to delete the temporary files and clear up every bit of space they took up. im going to post a guide for this, so check it out if you need help.

Lost ALL images and videos - will rooting possibly save me?

Hey all,
as I was backing up files from my phone (internal storage full, 500MB to go) via USB, and after I'd done a bunch of PDFs and what not, I wanted to start moving videos / photos. That failed instantly and after that, EVERY SINGLE IMAGE / VIDEO file was gone from the phone. I installed three "recovery" apps - they couldn't find a thing. I have a bunch of family stuff I really, really would like to have back.
I downloaded the MIUI unlocking tool and wanted to 'get going' with rooting, but I'm getting a "Unlock will erase user data" notification, for if I continue. This does not seem what I want.
- Can I continue without definitely trashing any hope of recovering files?
- Is there another way to get to files that magically disappeared (no Sync on, no OneDrive auto-backup, no nothing at all) that do not required root, and/or ...
- Is this a "known" problem? I cannot seem to find anything.
Many, many, many thanks......
As MIUI Unlocking tool says, it will delete all the data on the phone.
Whelp, this is happening. I'll give it a go before I can't get the files...
I have to wait 2 weeks for the MIUI tool to allow unlocking the bootloader. So I guess at this point I'd mostly like to know if the Mysterious Case of the Disappearing Files is something that's more common on the Redmi Note 5 - or on Android 8.1 / MIUI? I'd like to assure the reader at this point that, while threads like these are a dime a dozen and it often boils down to user error, I'm not a complete nitwit and assure you I was doing nothing other than Ctrl-X -> Ctrl-V to harddrive, got an error message, 40GB were magically freed up on internal storage and ALL files were gone. All of it. Folders too.
Updating thread title, hope that's okay..
Realistically, considering different "undelete" / "recovery" apps are not finding ANYTHING!!! at all, how likely is it even that something will be found once the device has been rooted? This almost seems like it had a system reset while it was still enabled...... Just everything gone / re-encrypted / whatever. Is that even possible? Again, though, the device DID NOT reboot. The files were there......then 40GB was gone.
It is possible to recover the data but the process will require root permissions. Install Disk digger pro from playstore. And give root permissions it can easily recover the most of the photos ( May recover all but possibilities are less ) Give a try bro it will definitely help you. As it helped me before.
I had something similar back when I had Redmi Note 3. Files just disappeared when I put them inside obb folder. However, they reappeared when I entered the recovery (it was custom) and I copyed them via cable onto my pc. They weren't there when I connected normally turned on phone to the pc, and it was annoying. So whatever you are doing, don't format your phone, otherwise you'll lose the files forever.
If rooting and installing an app to recover the files won't help, I suggest you flashing twrp and trying to find them from there using the cable and a pc, or whatever.
Thanks. It's a shame I'm finally "getting in to" rooting only now, now that I have a problem. When I tried many years ago I felt it was too complicated and most of all risky....
The main problem I have with rooting is that the Mi Unlock Tool wishes to Reset the phone, re-encrypting it in the process, and destroying any hope of recovering data. I intend to flash OrangeFox before it can reset.... Does anyone have a better idea....? It's really very, very much appreciated!
