I am running the -AZ [cricket] variant, and am rooted per Mohan's exploit. I decided to encrypt the phone for security purposes, but tapping 'encrypt device' after confirming the passphrase simply results in the phone powering down, rather than entering the encryption process. Has anyone else dealt with this problem?
I would do a master reset of the device and wipe your SD card with a format of the SD card. Then I would not restore your settings and then do a encryption of the phone, the do the SD card encryption the install your applications

Is there any way to enable the encryption via registry settings?
Even if I check "Encrypt files when placed on a storage card", then I close and reopen it and it's still unchecked. Encryption isn't working with different roms and different storage cards. Weird, because it was working in the past with an older rom but after a reflash of an new ROM it's gone.
Could it be a hardware problem?
Maybe there is a registry setting to force encryption? If not, maybe there is any software, that is running permanently in background and encrypts new data on the SD "in real time"?
Thanks in advance for any help.
Found it
check the windows reference here:
http://msdn.microsoft.com/en-us/library/aa912271.aspx
on on htc touch hd go to start >setting>system
you then have the encryption tool that says when you activate it
"encrypted files can only be read on this device "
so may be a daft question but when i have this activated can i connect my phone via active sync or as disk drive and still see the files and open them and my memory card ?
what im trying to get at is if anyone found my phone they can read the files as they have the phone. what has been encrypted ?
thanks
I'd say no
I'd also say reflash with another rom and you can't read it ever again
even hardreset the phone and you can never read it again
it's made to make sure you're most secret stuff never gets out if you're phone
is stolen not to make sure your stuff will ever be something you can retrieve if something goes wrong
are you saying that you think the encryption is not working ?
No. That's not what he's saying. He's just advising that you not use it. The encryption key is stored on your phone's memory, so that if you ever hard-reset or flash another ROM, the encryption key will be lost and you won't be able to access the data on your memory card, ever again. You would have to do a full format of the card to even be able to use it again.
thanks for clearing that up .
could you recommend any software that i can install on the phone that requires
password to access the memory card while still in the phone and require password if memory card was taken out of phone and put into a pc memory card reader
thanks
I don't really know of anything that would be compatible across multiple systems/platforms like that
I just googled this and found the following software:

Just some thoguhts for using the native encryption...
I wonder if the encrytion key can be extracted from the phone...?
That way it could be added again on another ROM. Also, the key could then be used in a desktop application that implements the same algorithm (AES, I think). This would allow the card's contents to be accessed outside of the phone.
Hello all. I'm fairly new to phone modifications. Yesterday I rooted my phone successfully, installed TWRP successfully, installed and operated cyanogen mod 14 successfully. Upon discovering I had to install gapps I removed the micro sd card from my phone and placed it into my laptop via a sd to micro sd card converter. I placed the file for gapps onto my micro sd card and when I plugged my micro sd card into my phone and tried to load it up into recovery mode it would not work. When I pressed 'Install' on the twrp menu the menu froze. I repeated the process multiple times to see if it was some sort of bug but the same result appeared. Upon entering my micro sd card into my computer after to see the state of the installed files it mentioned corruption and that I could no longer access them. Currently I am left with a phone without an OS to operate on. Can I simply re-format my micro sd card, install cyanogen mod again and then re-install it? If not does anyone know of any way that I can revert settings? Unfortunately the backup I made for my phone prior to cyanogen mod flashing was lost in the micro sd card corruption. Wish I had made a backup to my computer now :/ appreciate any help <3
Yes you can reformat your SD and use it again. After formatting it (not as NTFS or Mac OS extended), move the CyanogenMod and Gapps zips to the SD, making sure to eject it. Then, with the phone powered off, put the SD card in the phone. Boot into TWRP, press install, find the CyanogenMod file, tap it, and hit "flash more files" or "add more zips" or whatever the button says (should be to the left of "install") then find the Gapps file, and tap it, then press install. Then wait for it to finish, and boot! Then you have CM and Gapps in one flash. I've never had an issue doing it this way. Cheers on joining the community, and good luck with your journey.
I have been searching high and low for hours and cannot find anything related to my situation.
I am replacing my V20. The SD card is encrypted. I attempted to decrypt it on the V20 but it would hang at 1%. Sat there for several hours. I read one post that said I needed to disable screen lock and reboot the phone. I disabled screen lock, did NOT reboot, tried to decrypt gain, sat over night, didn't go past 1%. Rebooted phone, now I no longer have the option to decrypt the SD Card. I reenabled lock screen with same password and still no option to decrypt. I tried using Cryptonite to decrypt it, I get to a point it asks for a password, but then gives me an error stating there was a problem with file permissions or the password. The V20 is not rooted. Hesitant to root it and risk losing all of the encryption keys. Closest thing to a solution I have been able to find is to copy the files to a PC, format the sd card, encrypt it, copy the files back, then decrypt. This seems quite hoakie to me.
PLEASE HELP!!!!
The long way of transferring data to and from computer seems to be the only option

The problem is, the data is still encrypted and unreadable to the phone or computer. If I copy the encrypted files to the PC, format the SD card, encrypt it, then copy the files back, won't the phone double encrypt the files? Or will the phone recognize they are already encrypted and "unlock" them?
If I go this route as a test, will DD in Linux make a sufficient enough bit for bit copy of the SD card to restore it as if nothing happened? Is there a Windows alternative that would work just as well?

I think what Still_living714 meant was that you have to use the V20 to access the SD card and copy the data to a computer using USB or a network connection through it.

I understand that. But the V20 isn't even able to read the files even though they were encrypted on that device. Most of the files are not readable. So copying an unreadable, encrypted file, from the device via USB, to a PC, will still result in an unreadable encrypted file on the PC. I then format the SD Card on the V20 and reencrypt it. I then copy the still unreadable and encrypted file back to the SD Card which is in the same V20. Now the V20 is going to encrypt that file again making it double encrypted, correct? Or will the V20 recognize that it is already encrypted and give me access to the file since the lock screen password was reset back to what it was before this fiasco started?
Maybe I'm just not explaining the situation correctly.

Umm, that's not how the encryption on an external SD card works on android.
If the OS fails to decrypt the card, the whole thing is inaccessible. Android encryption is not a "per file" encryption.
Forget all of the double encryption nonsense. No file is ever double encrypted you simply copied encrypted files from the SD Card to new device/pc, and copied them back to a formatted and re-encrypted SD Card in hopes you can decrypt them. Thus, is there a way to decrypt it (period)? That's the real question!!!!
So, can someone answer the real question. Especially, I'm having the same problem after upgrading to a S10+ from a S8+ that I traded in. So, now I can't read nor access 14.3 GBs out of 16 GB SD Card; which is unacceptable.
I'm in a catch-22 situation. My S5's microSD card reader no longer works because the controller chip was damaged by water. The rest of the phone still works fine.
The SD card was used as shared memory (adoptable storage), meaning it is encrypted. Without the key (16-bit AES265) it is impossible to decrypt. I read that the key is in data\misc\vold but in order to get it, you need to root the phone.
Is there any way to root an S5 (Android 6.0.1) without the encryption key file being wiped?
Thank you so much!
UPDATE: I was incredibly lucky. The bootloader of my S5 is unlocked, so I could use odin to install twrp and then back up the key file. I also used twrp to make a full backup of the phone. So I will now try to restore the backup to a new phone of the same type, and if that doesn't work I'll decrypt the microSD card using this method: nelenkov.blogspot.com/2015/06/decrypting-android-m-adopted-storage.html
