Good morning folks,
I'm hoping XDADevelopers can assist me with an issue I've brought onto myself past couple days. I'm praying something can be done to recover my files! :crying:
I have an Galaxy S8+, and I encrypted my phone using Android's encryption feature (with a 4 digit pin code), and for some reason it wouldn't allow me to decrypt it. The option remained as 'Encrypt SD Card' via Settings > Lock Screen & Security > Encrypt SD Card, but when you go into it, it said that it couldn't decrypt the device as it needs the same device used to encrypt the SD Card in the first place confused:what? It is the same phone!!!). Burning up the internet trying to find a solution, I came across several forums telling me to do some of the following:
- Change Screen Lock Type to 'None' then try again - Failed
- Backup contents of SD Card onto PC, format SD Card on phone, encrypt SD Card (using 4 digit pin code), copy contents from PC onto SD Card, then decrypt it - Failed
- Wait it out - Failed
- Enable Developer Settings (I always do for the record) and enable 'Stay Awake' / enable USB Debugging, then repeat option 2 - Failed
- Mount / Unmount, reboot, etc. - Failed
When it was encrypted without any files on it, the option was now Settings > Lock Screen & Security > "Decrypt SD Card", so it seemed like an initial error occurred that made the SD Card think it was encrypted from another device,
Now the only copy I have of my files are stored on PC with no way of accessing it :crying:
I haven't formatted the phone yet, and I'm very reluctant to do so in-case i cause further damage.
Right now I'm in a constant loop of trying option 2 in hopes that it suddenly worked and allows me to access the photos! it managed to work once, but couldn't let me open the files from QuickPic app.
My questions are:
Can I recover my files? (from my PC)
Is there a way of forcing the encryption and encrypted files (stored on PC) back ONTO the SD Card after having formatted it?
Is there an app (either on phone or PC), that can force me to enter the 4 digit pin code (which was my phone lock, along with fingerprint scanner).
I'd very much appreciate any time and response regarding this.
Many thanks!

Hi.
I understand that it is unlikely that I will already help the author of the topic. But maybe my situation will be useful to someone else. Faced the same problem as the author. My memory card started to fail. At first, the phone lost her, but was found again after sd card being remounted. Then after some time the phone lost it again and did not see it at all. In this case, my laptop saw the card. I found that the problem is in LOST.DIR. Now the phone began to see the card, but it gave an error that the card was encrypted on another phone ("this sd card cannot be decrypted because it was encrypted on another device") (maybe the problem is that I inserted another card to check if this is a problem with the phone’s hardware). I tried the steps described above and the error reappeared. I tried to format the card and copy only a part of the files from the image and came to the conclusion that the problem is in one bit file in the DCIM/Camera directory. The phone apparently tried to scan the gallery on boot. It received a decryption error and stopped decrypting the rest of the content and just said that the keys are not the same. As a result, with long attempts, I found a broken file and successfully restored all other files.

I am using the Darkforce ROM of WM 6.1, after I insert a SD in my Universal, I found that aa file generated automatically called "EncFiltLog.menc". It will continuous exist no matter I deleted it or not.
Anyone know what is "EncFiltLog.menc"??
By the way, I am using Transcend 16GB SDHC. Today, I found that my PPC can't detect it suddenly, I tried to insert it on my NB, but there are some files halt! When I double click it and wait for a moment, a messege box appear and say there are some problem about I/O device. No any device can detect my card now, anyone know what's the issue? I even can't format it now...
Please HELP!!
THANKS YOU VERY MUCH!
.menc files
.menc files are encrypted files.
When you set the option to encrypt files (Start\Settings\System\Encryption) then anything new that is saved to your SD card will be encrypted (and will have this extension - although this extension doesn't appear when viewing from the device that encrypted the files).
To read the file, you must view it via your device. (You can view/transfer it onto your PC via active sync from the device that encrypted it).
If you have reflashed your device without backing up your SD via active sync, then I don't think there is any way of recovering the file . (NB. I copy everything from my SD card to my computer before reflashing, and then copy it all back again ).
Hi my friend!
I had the same issue but with things 4.1 ROM. I don't know how, but i tried every day to format my sd card, and after 5 days it worked I have also this file in the root... It's the encryption file i think...
Mine was a 2GB panasonic SD not an SDHC... Keep trying!
Thanks for all reply!
But I found that I haven't tick the option of"Start\Setting\System\Encryption" , but the file still exist! I don't know why...
Any my SD issue....
I an using this ROM for few weeks already, but not newly flashed. My SD have no problem before. Haven't backup the datas is my mistake! I am so regreted. My SD is now can't detect from all device, and I can't format it also.
ALL DATAS ARE LOST!! Just wanna cry!
damaged sd-card!
Hi! Had the same problem with my new kaiser. Also thought about problem of ROM or the device itself. But it was just the SD-Card itself. Bougth a new one - no probs anymore...
any true solutions to this?
I have this same problem, so the only way to fix it is to get a new card?
Step By Step To Delete File EncFiltLog.menc (EFLG.m)
1) Insert your SD into Card Reader Cut EFLG.m
2) Paste insde your PC
3) Defrag your SD card
4) Select Option Tools>Folder Options>View Select Show hidden file
5) Now you can see new folder ie File 0000
6) Delete the folder
7) Now your SD card become as original
I read somewhere (http://forum.xda-developers.com/showpost.php?p=2718217&postcount=9) that the hidden file "EncFiltLog.menc" is stored on every SD-Card by WindowsMobile weather encryption is activated or not.
So it should be no problem to have it on the card - as long as everything works.
About a month ago I purchased a Galaxy Tab Pro 8.4. Last night I installed a Samsung Evo 32Gig Micro SD Card. Seems like the tablet didn't recognize the extra storage, and I thought encrypting it might address that as it showed as an option.
Now my tab requires password instead of PIN, and I can't change it back. It is not giving me the option under security to decrypt the device or SD Card.
I have deactivated Samsung Knox, and Android Device Manger administrators, and the option to "clear credentials" which I heard may resolve it is grayed out and unselectable.
So long story short I cant figure out how to decrypt the device or SD card so I can go back to a PIN instead of password. It is not giving me options under security to decrypt the device or SD card.
Any help would be much appreciated!
I also forgot to mention, when I go into Lock Screen it wont allow me to go back to PIN either.

try putting the card in your pc and format to fat32. if your pc wont format fat32 look on google for a formatting tool to help you do it.
formatting will wipe off the encryption.

try to format your sd card using formatter pc app just google it to find that app and guide how to use... but before you format it need to back up all your files stored in your sd...so you can restore it...
I can't edit, remove or format my new SD card.
after I bought a new SD card and moved my backup files from a PC, I connected it to my Sony Xperia Z5 (Android 7 (not rooted)
then a notification came asking to select if I want to set my new SD as internal or external storage and I ignored it.
and from that time it is not allowing me to do anything to it except reading it files (it doesn't even show photos in photos app (just show files in file manager)
anyway I tried formatting it through PC and it keep saying "device is write protected"
tried regedit and diskpart methods and nothing worked.
tried formatting it through other android device and still unable to format it.
any solution?
Hello guys,
My partner changed her SD card without realising the exisiting one was "adopted" as internal storage. All of her photos of our kids are on there. She clicked "forget sd card" at the prompt without realising this makes the SD card essentially useless to recover the data.
Is there any way to recover this data? Obviously the PC does not recognise the SD card as its encrypted, so we cannot pull the photos off that way. The phone asks to format the device so I cannot pull the photos off with a usb cable either.
From what I've read, the phone generates a key for the encryption using the screen unlock pattern. We know what this is, so have a chance of unlocking the SD card as we know what the master key is. The phone is not rooted- as far as I know this changes the encryption on that end, so any attempt to root the phone to get access will not work as the keys will not match anymore. Are there tools to brute force the encryption on the SD card? I would hate to lose the data on this.
Thanks
Hi everybody
I had to wipe my S7 edge due to the pattern not being recognized (known bug) and I would like to know if there is any hope recovering my pictures from my SD using software, when I googled "recover photos encrypted sd Android" the first page is full of software, some form easeus, rescue digital media, Yodot, etc, I even found one that say to just copy the files to a pc, wipe the SD card on phone, copy the files back to SD, encrypt SD and the decrypt and I should have my pictures back, I try this last step as it doesn't require any software but still wondering if any of the software mention will work
thanks
