Good evening (subjectively) all.
I've just recently encrypted an HD 2.* ROM on my Nexus. After encrypting the device today, it appears I have no access to the SDCard in CWR.
Can anyone give me any advice? How do I unencrypt (if I must) or fix the situation ?
My impression is that right now, you can either encrypt the device and keep it stock, or stay unencrypted if you want to mod the device/enjoy CWM. Maybe I'm wrong (I hope I am!), but I've just heard that encryption causes too much pain to be worthwhile if you want to do anything non-stock.

I had this problem! CWM can't see the sd card as it is encrypted. You need to do a full factory reset to remove the encryption. Google does't allow the option to decrypt yet.
Unfortunetly when you do a factory reset it wont work as it is looking for the stock bootloader to complete the wipe and it won't be able to use your existing bootloader. World of hurt!
The only way I got around this was to adb/fastboot the original stock rom. This caused me so much pain! Even then I had to do it once or twice before it fully worked.
Let me know how you get on.
Hey guys, sorry if this has been answered somewhere else, but I just want to confirm my understanding about encryption.
I'm setting up MobileIron and TouchDown for my work email and paused when the IT policy asked me to encrypt my phone.
So, is doing encryption will make it impossible for us to flash rom, radio, any kind of flashing + impossible to do all other things in CWM - due to the partition is being locked and encrypted before the device boots up?
(I'm not good to explain it technically, hopefully you get what I mean).
Slower boot time? The only way to decrypt is to factory reset and wipe all data? Impossible to backup nandroid? etc etc...
Of course the device would be more secure from the company's security point of view, but is that it?
I'm pretty sure there's no other workaround if I want to setup my phone with work email, since of course the IT policy applies to all employees so I can't ask for an exception.
At the same time I don't want to lose my ability to flash just because of the work email, it defeats the purpose of me having Android (which is to tweak and mess with my phone).
I came from SGSII where the IT policy only enforces PIN/password/pattern requirement, or perhaps because SGSII doesn't have encryption capability.
Appreciate your comment and opinion guys.
Hopefully someone knows.

Once your device is encrypted you won't be able to flash roms because recovery can't see the SD when you try to flash a kernel or rom.
You can't remove the encryption through a factory reset if your device is rooted and running CWM recovery. It will fail and the phone just boots up as normal. The only way I was able to remove encryption was to ADB/Fastboot the stock images onto my Nexus.
Lastly, I noticed the phone being very slow to boot with encryption.
Until Google give the option to decrypt I won't go near encryption again. Hope this helps and answers some of your questions.

I assume any kind of flashing won't work with encryption, including rom, kernel, radio, circlesmod, and all other kinds of mods that require flashing from CWM.
Is that correct?
If that's the case looks like I'm not going to use my work email on my phone.
Yeah your assumptions are correct!

I'm in exactly the same situation, unfortunately found out that i can't decrypt it with factory reset after I'm already encrypted
Do you happen to know good tutorial for flashing via ADB/fastboot?

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.

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.
I recently just wipe did a factory reset on a encrypted (factory encryption) Galaxy S3, after rebooting it i have found that i am unable to get past the initial password prompt screen. I have tried to flash stock ROM, multiple times, to no avail as after each reboot i get the same password prompt screen. i have tried to flash custom ROM, multiple times, this to to no avail as it will not even go onto the device through push in Samsung toolkit v7 or slideloader. i have wiped the ROM to the point of nothing being on the phone and re-installed the factory ROM again this to with not avail as it still has the password screen. Now before i go back to t-mobile and see if they will help me, i decided to get community input to see if there is anything that can be done outside of the Factory as i have void warranty using Samsung Galaxy S3 Toolkit v7.
******UPDATE******* for those with similar problem, i just fixed this. Issue is as follows with possible fix action:
Issue was that encrypting the Samsung Galaxy S3 with the factory encryption and then wiping the system will cause the password file to be deleted but the encryption to stay on the phone. My fix action was that download original ROM from the provider, delete existing ROM on phone till it is basically a brick with USB debugging on and re install the original providers ROM. After it is re install you have to go in and wipe the phone's data one more time. This resulted in the password prompt screen disappearing and the basic start setup being initiated as if you just bought the phone from the store. Although this is my fix and other fixes for future reference would be much appreciated to. *********UPDATE************

When you say you reinstalled the original provider's ROM, I'm not sure if you mean you used ODIN. I believe ODIN install is the only way to recover from this as it reformats the partitions.
An ODIN flash back to OTA did not help my issue.
My company now requires the encrypt device policy for exchange, so I went ahead encrypted the device while running CM10. The encryption succeeded, but every time the screen timed out, it would turn off the device instead of just turn off the screen (CM10 bug?) - didn't want to have to deal with having to cold boot the device every time I want to do something, not to mention the phone being off :/
So I did a nandroid restore to my last known state and now I get prompted for the unencrypt password. However, the password doesn't work. Probably because the password file was deleted, but the system and data partitions are still encrypted.
I've tried doing a full wipe in TWRP and flashing multiple ROMs. I've also tried ODIN flashing root66 and OTA JB 4.1.1 with no success. It still asks for the unencrypt password. I suspect the only way to fix this is to completely re-create the system and data partitions.
If anyone knows how to accomplish this, I'd be grateful because I have a soft brick right now (i.e. can't get past unencrypt password prompt with any ROM)
OMG THANK YOU SO MUCH FOR THIS. I was in the same exact situation you were in and thank god for this thread. I thought my phone was pretty much done for.

Hello,
I don't know if any of you have seen this on a Note 7 since its still relatively new. Do any of you know why this mean?
Encryption Failed
Unable to start up you device. The encrypt precess was interrupted. you need to reset your device to factory default settings. This will erase all your data.
(And a RESET DEVICE button) which does noting but reset the device to start back at this Encryption Failed screen...
Thanks
Have tried to factory reset the phone from recovery? If that doesn't work you probably have to flash ROM via Odin.

Just wondering how serious is this? Out of all the phones I've played around with for the last 7 years this is the first time I've see this. I'm $hitting bricks!
I would try to factory reset like it recommends. If that doesnt work then time to exchange the phone.
Good luck and let us know how it goes...
Also, did you try rooting?
Yes I rooted. Alright so I managed to resolve everything THANK GOD!! I thought I was down CAD $1200 (not including customs)... Main problem was I didnt mount the System in TWRP before formatting, so no matter how many times I tried to format and install the only custom ROM available it would show me that error. But all is well after getting the stock ROM from Samsung and formatting it trough Odin.
