Hello guys
I need a help about decrypt my Moto x , I have encrypted my phone a month ago to keep it secure but now it has got annoying for me to unlock my device at ever reboot. I want to decrypt my encrypted device without losing all my data. Please friends if you have any knowledge about please Help.......
Thank you friends in advance......
Sorry but it's not possible. You have to backup what you can and then wipe data. This is the only way to turn off device encryption.
Can you encrypt a phone without losing all your data?

AFAIK, you can encrypt without losing data, but you can't decrypt.

As we know google is going to pre enable the Data encryption on Android L and we already have it as an optional extra security ..
So before anyone rushes to enable it to feel more Secured . First let's learn about it ..
As this option is available in Security .
If you enable it you have to enter password/PIN(compulsory) ..
80% minimum battery + plugged in for charging is necessary .
Once the encryption starts it will take about 15 minutes to complete the process ..
Once it's complete , it will automatically reboot the phone . booting will be in 2 stages.. On first stage it will ask for password/PIN to decrypt the phone/phone storage
And then the second boot process will be the normal one ..
And now comes the warning part ..
Once you encrypt the data , you have to decrypt it on every boot and you can't disable this .. You have to factory reset the phone to remove this .
And here at XDA we flash mods and zips etc almost every day/week ..
So if you encrypt your phone and then you flash anything via bootloader ..IT WILL FORMAT EVERYTHING ..(including internal storage, basically factory reset)
So if you are an advanced user with custom rom/recovery etc i suggest you to first do a complete backup If you really want to try the data encryption .
So i hope this information be helpful for those who are unaware and don't know what can happen , and i suggest you to read about it before you enable it ..
For most of us, we already know that encryption causes issues, always. Maybe not immediately, but always at some point.
Its the new people that go "oh encryption, sounds good, must use", when they don't have any data that's actually important enough to justify the need for encryption.

That's why i created a new thread specially for those who are inexperienced .
Not everyone are born developers/pro
Everyone learns with making mistakes
And our Job is to help them at XDA .
IMO this is what XDA is for at the first place ..
I'll rely on custom ROMs as always, that certainly have it disabled by default.
I think it's insane google would try to force this on us. Shame on them. ?
How does android L handle staying unlocked in trusted areas if encryption is enabled?
Despite the warning, we will see how the encryption will work in Android L. It might not be the same process as described from Kitkat/JB of encryption.
Who know if the process of encryption will be changed in Android L, so that you don't have to do each step to encrypt/decry pt and the flashing/modding issues.
I see many bricks coming from this as well, from unknowing flashers.

Probably they are going to change the way it works .. , because they haven't updated it since it first came out with ICS ..
The inability to use pattern lock is enough to turn me off Android encryption. All the other problems just makes it a no brainer.
May be they have overcome these issues and thus made it default....
I find no sense in making some hectic procedure as default
wow. wonder who will have access to the encryption keys.. or more likely supplied the encryption technique in the first place?
cough... nsa, feds, gchq, ect...... cough
don't believe the security services fake crying about encrytion... just a fairy story to pacify the sheep

When NSA forced TrueCrypt to hand over their keys, they essentially and purposely updated their product to be broken to ensure no one used it. Wonder what Google would do?

You can't do it out of the box, but you can make it work fairly easy with twrp and a backup. The quick version is:
before encryption, setup your pattern lock, do a nandroid backup in twrp. Reboot, change to a PIN/password to allow encryption, perform encryption process. Boot back into twrp, it will prompt you to enter your pin/password, since it can decrypt and then function inside of the encrypted volume (and therefore restore an unencrypted backup inside of the encrypted envelope in essence). Restore your backup that has pattern unlock and reboot. It should prompt you for your strong pin/password on each initial boot, but once booted, it will use your pattern unlock. Downside is you can't change your pattern after that, so pick what you want the first time. You can change your pin/password if you want, I use EncPassChanger myself. I also use bootunlocker to relock the bootloader after I'm done, just have to make sure to unlock before flashing any updates.
I use this process on both my N5 and 2013 N7.

They can't really openly say that buy the industry "knows".
But the opening paragraph of this page hints at it.

AH OK thanks. I thought there was some recent, concrete news about what went down.
Thing is, now what will we gotta do to still be able to flash zips with encrypted device? XD
So I recently encrypted my phone....because I read it only encrypts the data partition...so if I wanted to update my CM11 version (m9 to m10 for example) I wouldn't be able to?
I should have read into it more I guess...
edit: TWRP saved my ass. Just looked at it and it decrypts the data partition.
I encrypted my phone, but now wish I hadn't. I'm pretty sure it is the cause of some small issues I have had flashing different ROMs.
fml :crying:
Hey guys i wasn't real sure where to ask this but its very important to me that i figure this out.
i have a sm-g900a and i successfully rooted the phone. i never installed bootstrap or any custom recovery mod because i didn't get that far yet. i haven't put a rom on the phone either. i recently have been put in a situation where i need to encrypt my data, remove the data and wipe it clean so that absolutely no data can be recovered. this of course i know is hard to do without destroying the memory itself haha i just need to figure out how to get as close as possible to non recoverable data as possible. now for most encryption would suffice but my encryption program is not working so i need to fix that. this being said. data encryption can be decrypted if the password is found somewhere on the system. is there a way for me to delete the data and its residue off my phone so that it is not recoverable.
So I just got N6 that asurion sent me to replace N5. Now I am rooted and xposed installed. I'm trying to get rid of encryption but am not clear how it works. One the file needed I have not been able to find for my build (LMY48I) Will I have to roll back to previous version of lollipop to accomplish to remove the encryption? Also since im rooted and unlocked will my date need to be erased, if so if I do a nandroid backup will I be able to restore from it or will that return the encryption. Thinks or the help.

all you need to do is flaah a cystom kernel that allows for decryption, then you have to format your storage. when you boot, youll be decrypted.

You can find several unencrypted kernel options for 48I in Android Development. No, you do not need to roll back. Yes, your the contents of your SDcard will be wiped when you do "fastboot format userdata" to enable unecrtyptable kernal.
Thank you both for the quick response. So after I remove the encryption and am completely wiped...would i then be able to do a nandroid restore, or will that result in me being encrypted again or create other issues?

Not wiped, formatted.. And no...
Hello all.
I always keep a pass code on my phone and use smart devices and locations to keep it unlocked in trusted places. I am thinking of turning on encryption to keep the data secure if the phone is ever truly lost.
I am running CF's rom on an unlocked bootloader. If I backup in TWRP and store that backup on my PC, what would be the best method of restoring it if I find the encryption to be too much of a burden?
Also, is the recovery partition encrypted when this is done? If so, how would I actually factory reset to remove the encryption before a restore?
Thanks!
I'm not an expert on using encryption on an unlocked bootloader, but from what little I've read and tried, it can be tricky. I am also using CF's rom, and whenever I try to encrypt the device, the screen goes black and won't respond until I hold down the power button for a pretty long time. I've read that you need to be on a 100% stock rom if you want to encrypt the device, and then after that you can modify it as you please. The recovery partition is not encrypted. That's about all I know.
I have always had my device encrypted. I can't recall a single issue. BL unlocked. CF 1.2.7.

Had you encrypted before installing the rom then?

I don't recall precisely, but I strongly suspect so.
I was bored, so I reflashed the stock rom and encrypted the phone. Took only a few minutes. I don't really see what the point is though, since it doesn't ask for a password at boot like it's supposed to.
Also, as long as you have TWRP installed, anyone who is even slightly knowledgeable can have 100% access to all of your files, no password required.

Interesting....mine requires a PW at boot....
Additionally, I have to type my PW when booting into TWRP.

Oops. I figured it out. No lock screen password, no boot password.
It appears you have had success where others have not. Were you successful in having TWRP decrypt your data, in order to load CF's ROM?
I've downgraded to 4.4.4 stock, encrypted the phone, loaded TWRP through ADB, and cannot get TWRP to decrypt, no matter the password I use.
Any help would be appreciated.
can you give downgraded 4.4.4 file for my turbo

Title says it all. Is there any known way to have root and device encryption still possible?
Thanks a lot.

Not currently. Unless you can trick the device into thinking it's fully charged and plugged in at the same time??

I never thought of this question, but good question. So root trips knox to stop encryption? Kinda lame if so.

Got it working with the stock ROM in the mean time. Just don't use TWRP to flash Magisk. Keep the stock recovery, Use Magisk Manager to patch boot.img (check tar format in settings) , then flash back via Odin, boot and factory reset. Done.
No luck with any custom ROM yet. Desperately looking for help. Would also pay quite a bit to have someone skilled looking into this. I don't want to keep the Korean ROM of my N950N

No, flashing with TWRP requires to format data. That step loses encryption.
For some reason it's then impossible with Magisk or pph root to just reencrypt the phone from a custom ROM. It dies with invalid encryption and looses all your data when you try.
It's a bit different with SuperSU. Here it thinks encryption went well and tries to mount it on next boot, but then fails.
From my current knowledge it seems it needs stock recovery to recreate an encrypted data partition that actually works. That's the bit I'm stuck now...

On the Snap version, using SamFail gets rid of encryption. There's no way to encrypt for us with root because of the 80% short coming.

Ah crap, didn't even think of that issue
Anyway, at least to me a phone without reliable encryption is not usable as daily driver. I wonder why this gets so little attention. I spend some days now trying to resolve this, but there is not much information out there or I'm not capable to dig it up.
I couldn't even find a clear statement, what it actually is that prevents TWRP to mount encrypted /data on modern Samsung phones.
I known they do their own SOC based hardware encryption, but what is it that TWRP can't get? Does the trusted zone not release the key if a custom binary boots? I really like to understand a bit more on how this actually works.
Thanks
