Rooted and unlocked the boot loader in my nexus. Then installed the modaco zip with cwm to my phone. All working great. Then to use my company email I let it encrypt my phone. Still all worked as expected. Now I want to get rid of encryption as cwm now can't mount the SD cos of the encryption. Now I am stuck. A factory reset won't work. Cwm can't access the in built SD because its encrypted. What can I do? Can I wipe the phone and some how push the zip file to the phone from my computer? What would you do if the nexus was bricked? How would you push files to flash from the computer?
Any info would be great.

Depending on what solution(s) your company is using to encrypt and manage your phone, it's possible only your sysadmin can undo the encryption. Of course, that'll mean no more company email going to your phone. For obvious reasons, your company's policy is probably ironclad, and you could risk reprimand or even dismissal if you willfully disobey it.

Hi!
I was forced to encrypt my galaxy s3 in order to receive corporate emails on my phone using the stock email app. However I never imagined that encrypting the phone would literally lock the memory and options to customize the phone.
I tried to root the phone to benefit from more flexibility and also debloat the phone. However during the rooting process, I could not mount /emmc/ when using ClockWorkRecovery in the startup menu. Based on what I found on the web, I figured it was due to the encryption.
I then tried to factory reset the phone to get rid of the encryption but I simply can't hard reset the phone from the OS or the startup menu. When doing the reset from the startup menu, the errors are "Can't mount /sdcard/". The reset continues but when the phone reboots, all my applications and personal data are there and the phone is still encrypted.
I read a lot about flashing a custom recovery via flashboot or ADB but I am reluctant to do it without guidance from the experts (you guys).
I deleted my corporate email account (It is my personal phone, I am not required to install exchange on it).
I tried to use an external sd card but as soon as the phone recoginizes it, I have to encrypt the card as well as a result from the corporate policies. I ejected the card and did not encrypt it.
I am new to android (long time iPhone user) and I would really appreciate your guidance on the methods to factory reset my phone or a different technique to get rid of the encryption because I am really stuck right now.
I have never encrypted an Android phone before. But maybe your response to these questions will serve as a "bump" to this thread.
1) What method did you use to encrypt the phone? Stock or 3rd party encryption?
2) Doesn't that same method also offer you the offer to unencrypt the phone?
3) If you used a stock method of encrypting the phone, then I'd assume your provider (AT&T?) tech support should be able to help you unencrypt it.
Eddie,
Thanks for your response.
1) I used stock method for encryption
2) Decrypt the phone is not possible apparently,only way is to factory restore the phone apparently
3) I went to the AT&T store and they were unable to factory restore (using the standard methods). They offered an exchange but since I purchase over the phone at a discounted price, I have to do the exchange using that method. Before shipping back the phone, I was wondering if I could fix it myself with the help of knowledgeable people.

I have never used the encryption but if the phone can turn on and is usable, cant you go into the encryption settings and turn encryption off? then you should be able to do anything (may be best to start with a factory restore first just so you have a fresh slate to work with)

1ofaKind,
Had EXACTLY the same thing happen to me. Encrypted my S3 in order to access work exchange server. Tried CWM but cannot mount /emmc/ problem after booting into recovery. Have not tried to factory reset yet as I am wanting to learn more before I go that route. But basically I am in the same boat as you. The only difference is I was not required to encrypt an external SD card when I put it in my phone. Read about flashboot as well...maybe the only way to actually factory reset after encryption??
Sorry I cannot offer any solutions at the moment...but I will keep scouring the forums looking for a way.
If I learn something valuable, I will try to post it here to help ya out.
EDIT: Maybe you have read these threads, but there is some decent info in them. http://forum.xda-developers.com/showthread.php?t=1451655 & http://forum.xda-developers.com/showthread.php?t=1392037

Look into using Odin to restore a factory image.
Sent from my SAMSUNG-SGH-I747 using xda premium
I'm in the same boat here - had to encrypt my GS3 in order to receive corporate (Exchange Server) emails. Now can't update the OS on the phone which is more important to me than receiving corporate emails on the device.
Can someone tell me how to decrypt (UN-encrypt) the phone? Everything I've read says that a factory reset won't do it.
Please help!

Has anyone tried this? If so, did it work?
I clicked install rom from sd card in cwm selected f/w which i had copied into internal memory. Did factory reset in recovery.
Odin it back to stock.
This might be too late to help you guys, but here's what worked for me. I odined it back to stock. Then I went into recovery (volume down, power and home button) and selected wipe data/factory reset. This does of course erase all your data, so try to copy whatever you can onto a computer or something before doing this. You should end up with an unencrypted storage.

After you hit start, unplug then replug the usb from the computer. I had some issues with it not recognizing it either to flash stock, but when i messed with the cord, it made the noise that i unplugged and it started working. Same thing with the root injected, only this time i fully unplugged it when the fiddling with it didnt work. Make sure you replace it into the same com port.
so, i seem to be having the same problem as all of you, only i encrypted to protect my data from agents. So, right now, i am *hopefully* :fingers-crossed: installing the root injected JB now. I had many issues. TWRP and CWM were no help, couldnt see phone to add new roms to it. ODIN was the only hope. I booted into recovery after going back to stock, did a new factory reset and am installing the stock with root. When i let it boot, it didnt go to encryption this time, but the first time i flashed the stock, it did. This is a mess to say the least.
EDIT: YEAH! done. No encryption and i got root. i used the image from here: http://forum.xda-developers.com/showthread.php?t=1968625 DLK3 worked for me. Good luck. i hope this helps. Ill be happy to explain more if you want.

ODIN (for me at least) wont see anything since im using Windows 8. On Windows 7, however, it works just fine.
Factory reset encrypted phone
hi,
I'm using CM11 as a rom.
I didn't want to reinstall stock rom, just to root it again later.
Installing updated version from external SD didn't work (updated the ROM but no decryption)
Tried to factory reset from recovery - didn't work, as the internal storage is encrypted it can't mount /sdcard/
however, from within settings menu, in backup&restore there's an option to do a factory reset - this is formatting internal memory altogether.
worked like a charm.

I understand this is very old but I am going to make a note here in case anyone else gets into this problem. When you go back to stock, do the factory reset using the STOCK recovery. Don't install TWRP or anything else until you have cleared the encryption. At least, that's what worked for me.
just installed 20121222 cm10 att nightly, and found my lock screen changed from 6x6 to 3x3. my code does not now work to unlock the screen. any ideas how i can log back into my phone?
entered a code >40 times in the hope that a google login screen would pop up and allow me to bypass this lockout.
failing that any hope for getting off a single file that i forgot to backup before flashing this rom?
very grateful for help.....
This is a known issue. Before updating it has been advised to remove pattern locks, unfortunately it wasn't detailed in the OTA.
There are only two solutions.
1) Download the following app from the play store. It is 4.20 USD and not a guaranteed solution. Follow the solution in the app's description. https://play.google.com/store/apps/...dium=organic&utm_term=android+lock+bypass+pro
2) Do a factory reset in your recovery mode. This is a guaranteed option, but you will lose your data.

If a proper back up was made before flashing (as recommended,i believe),a factory reset will not take too long to get back to the way you are now
thank you both for taking the time to help. I reset the phone to an earlier backup and swallowed the loss of data.
note to self: backup daily not weekly!
So I wanted to use my phone at my new job instead of being forced to be use an Iphone!! In order for me to use the phone, I had to set a password and encrypt it. I set the password for the lock screen. Then started the Encryption. Once I started it, I saw the droid bot and I left for lunch. When I came back the phone was done and when I picked it up. It asked for a password to decrypt the phone. I was never prompted to enter a passwd. So I tried to use the lockscreen password. That didnt work. I then tried to get into do a hard reset, the hard reset completed, but it still asked to decrypt. I then reflashed and it still doesnt work...I'm completely out of ideas. I need some help. FYI I'm using CWM 6.0.4.5
Fixed it

So I gave my mother my note 4 rooted Ultimate Note7 Hybrid SM-N930P and I wiped everything before I gave it to her. But when setting up her phone it asks for pin number for screen lock so I make one. Then when trying to unlock it it won't allow it. It looks to go to the next screen but flashes then goes back to lock screen.
Any help would be appreciated.
Thank you

Maybe a little late to reply but what did you wipe?
Recommended way to turn phone over to another user is to remove fingerprint(s) and accounts while booted. And make sure the reactivation lock isn't enabled.
You can factory reset after the above.
Maybe you can still factory reset but if that doesn't work, I don't know why it wouldn't unless reactivation lock is enabled.
Did you try the factory reset? Did that work or no?
Edit: if it's just a persistent fingerprint issue, try this but read the whole thread.

Flash this zip file from twrp or any custom recovery and it will bypass any lockscreen security lock. pin/pattern/password/fingerprint.

I wiped it from recovery mode with the TWRP
It isn't a finger print issue. It's the 4-12 digit pin number

Trying to help so I won't debate the issue. It's important to recall if you went back through setup wizard and were prompted for original user and account password.
I still don't know what partitions you wiped. You likely need to root again if you wiped data or factory reset. I thought a factory reset would remove fingerprints.
The reason I think it's a fingerprint issue is the prompt for pin after reboot. I think that still applies since it asks for one and won't unlock. On initial prompt after you wiped it, did you input your personal backup pin to unlock and set another pin? Original pin should be wiped but if not your accounts and likely prints still exist.
I may be wrong but you may have to restore a stock backup or go back to stock tar in Odin if the two suggestions given aren't helping. I'd suggest the same stock tar as before in case it is factory reset protection causing the issue. You may have use your original Google or Samsung account user and password to unlock it.
But before following through with Odin, one important thing to look for in phone's display is reactivation lock while phone is booted to download mode (for Odin). If enabled, factory reset protection is applied. I wouldn't flash but pull battery and factory reset and sign in with original user and password. The prompts should direct just that. After setup wizard, remove anything of yours like fingerprints and accounts and factory reset within system Settings app.
As I said in my initial reply, you need to remove your accounts and check for fingerprints and remove those if applicable. Then factory reset. I didn't mention it before but factory reset in system Settings app is recommended to avoid issues handing phone to another user. Not sure but it may be a more sanity check to ensure you've removed accounts and fingerprints and encrypted data. I forgot to mention encrypted earlier.
