Question on "Phone Encryption"

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!

Factory Restore an Encrypted Galaxy S3

Model: Samsung Galaxy S3 AT&T i747
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.

Edit Oct 17, 2014 - Encrypt your device/phone with custom ROM

Disclaimer: I am not responsible for any damage or liability arising out of these steps. I did not invent anything, I just tried something. Only move forward at your risk
If you don't agree ... stop reading and move on...
Background: Our phone has access to so much personal information that its scary if it fell into wrong hands. The only way to fix this is to encrypt phone. I did lot of research and here is a working solution that works for me - try at your risk.
Download Links:
a) Tested with ROM Stock 4.4.4 NH7 Galaxy S4 M919/Jfltetmo by @ShinySide
b) Tested with ROM |ROM|★KANGAKAT★|►KTU84P◄|4.4.4|Xposed|►8◄|6.26.14 by @iB4STiD
c) stock recovery AT&T S4 works with M919
d) Philz/CWM custom recovery
Encrypting with custom rom
1) Assume you are on custom recovery. - Backup everything first. Create a nandroid backup
2) Do a full wipe and install one of the two roms linked above (I have tested with few other roms ... none worked). Start the phone and set it up the way you want. Install all apps etc.
3) ODIN Stock recovery. See #c under download above. Its AT&T stock recovery but works for me. You need to know how to ODIN - find out. Doing this wrong will permanently damage your phone
4) Start your phone and turn on encryption. You will need to set lock type = password and will need to connect to charger and have 80% charge.
- Phone will do blank and stay blank for 20-30 minutes. Do not do anything. Encryption is happening behind the scenes.
- You might have to do this twice or thrice if it did not encrypt first time. For me the phone went blank first time and after 25 minutes it restarted but device was not encrypted. I redid the same steps and worked second time.
- If you interrupt the encryption process (battery pull or power up) you will see error message (encryption failed, reset device)
5) If all goes well you now have a password protected encrypted phone with custom rom!!! Check in Settings -> Security
6) You may install custom recovery ... but I don't see the point because you will need stock recovery to decrypt
To install another ROM
1) Reboot into stock recovery, then wipe data and cache (this removes encryption).
2) install your recovery of choice and install ROM using recovery. Philz/CWM

How to Flash a rom on an encrypted Android phone (specifically this one, the I9505 SGH-I337).
The Problem: Once encrypted, you can't decrypt it easily. When encrypting the phone android will tell you you can only decrypt it using a factory reset. Naturally you assume it's talking about the "Factory Data Reset" option found in Settings --> Backup and Reset. But noooo, Android is lying through its ****ing teeth. Then you'll assume you have to wipe everything from your custom recovery mod (CWM, TWRP, or one of those). Wrong again! You'll get beautiful "can't mount /data" messages and more bull****. I read about a workaround that required installing the new rom using ADB, but I had ingeniously disabled USB debugging prior to wiping everything, so I only got so far with that option (plus it's tediously long if you haven't installed all the necessary software already and don't feel like bricking your phone because you made a typo in the command line). So, apparently the only other way to really format that partition free of its encryption is to use a stock recovery. So:
Short Version for Godlike users who know automatically how to do all this **** without any help (mimicking how most help posts are finely detailed on this site): Flash stock recovery, wipe everything, flash your custom recovery and install your new rom.
Long version for us mortals who don't know everything and haven't already downloaded already every single bit of software on earth:
Backup all the stuff you want to save. This process will truly wipe EVERYTHING. You can do it manually, or you can use an app like Titanium Backup Pro to help you (find it on Google Play Store). Here's a nice guide which recommends what to restore and what not to restore: http://forum.xda-developers.com/showthread.php?t=1480343
Flash the stock recovery using Odin. You can download a stock recovery from here: http://forum.xda-developers.com/showpost.php?p=49687791&postcount=3 It's the link called "I337MK2stockrecovery.tar.md5" In case you don't know how to flash it with Odin, this short guide will help: http://forum.xda-developers.com/showthread.php?t=1506697
In step 6 replace "recovery.tar.md5" with the stock recovery you downloaded.
Wipe everything from the Stock recovery console. This little ****er will **** up the encryption all those sissies couldn't touch. You're welcome. You boot into recovery mode from a turned off phone by pressing simultaneously the volume up key + the home key + the power key until you see blue text appearing in the top left corner of your screen.
Reinstall your custom recovery. In my case I had installed the rom BEFORE flashing in the stock recovery (apparently it works, you just can't boot because of the encryption), so I was able to boot into the new rom before I returned to my custom recovery. Weird. Anyways, I recommend CWM. You can pick it up from this link: http://goo.im/devs/philz_touch/CWM_Advanced_Edition/jflte
For some weird reason they call the I337 version the "jflte" version. It's bonkers. Click there, and download the latest version that ends with .tar.md5. This version is upgradable via Odin, which we already used. Use the same instructions used as when you upgraded the stock recovery rom.
Boot into your recovery mod and flash your rom like you usually do.
A word about TWRP: it cost me many hours of work and I don't recommend it. Its website is outdated, and recommends using GooManager (which is no longer mantained) and doesn't work anymore for this. GooManager suggests using a new, different app, which doesn't have the option of installing TWRP. Then I tried using their TWRP Manager app from play store and the image file wouldn't download. Then I tried manually selecting the image file in TWRP manager that I downloaded from their site for use via the ADB method, and it bricked my phone... twice (using two different methods the app sugested). I tried so much because in theory TWRP has the ability to decrypt android's 4.4 encryption, but after looking at their github site I noticed it was filled with people's reports (including people with the S4) on how it wouldn't work decrypting squat. So I gave up, and installed CWM in 30 seconds.

I don't know if it matters too much or not, but the stock recovery you linked to is for the AT&T S4. A good rule of thumb is to never use Odin to flash anything not specifically for your particular device... In this case the M919.

I have tested stock recovery on M919 .. it works

Honestly im surprised its not talked about more since there is a big push for personal privacy when it comes to data. Encryption really is a pain in the ass to work with on android. Figuring out how to switch or update custom roms while encrypted will drive you insane. The easiest way is to just odin back to stock and start over, but that requires a computer anytime you need to flash anything.
I recently was trying out one of the 4.4.4 GPE roms and turned on encryption. It worked great until i started missing touchwiz and wanted to go back to HyperDrive TW. So the journey began...
First of all, i backed up everything to external storage since i knew everything on the internal storage would have to be wiped. I loaded the phone into recovery mode (using TWRP) and tried wiping, but all i got was a bunch of "Failed to mount" errors. Fine. Got the same error when trying to factory reset or wiping /system, /data, /cache, and anything else. Tried formatting to different file systems and then formatting back to the original but no luck. Fixing permissions didnt help. I just kept trying everything available multiple times.
Eventually it started wiping everything except the /data mount. Well... At least i could install new custom roms. Im not sure exactly what did it because i was just throwing everything at it. Anyways I got it to install, and booted into it. Nope.
Now it was saying I needed the password to decrypt the internal storage. It would detect wrong passwords fine, but as soon as i put the correct password in, it would allow me in, show the green android encryption picture, then blank screen. I thought it was just decrypting and setting up my rom but after a few hours my screen was still black and nothing was happening. Pulled battery and went back to TWRP.
I started wiping everything again and again and tried doing everything i could to wipe everything on the internal storage. Again, not sure what did it, but eventually got it all cleaned up and got a new rom installed and could boot into it.
The whole process probably took about 6-7 hours...
I dont even want to enable encryption on the new rom...

Yeah Encryption does not seem to work on TWZ roms. I tried on G Eye without luck.

I have updated op. Please check

Encryption will slow down your phone quite a bit. More battery usage + more CPU usage + slower phone = not worth it unless you've got some very private stuff you don't want being shared. Otherwise, 3rd party apps that lock a lot of files, can encrypt certain files, and hide others will do the trick perfectly well.'
Not trying to bash fully encrypting your phone, but I've tried it before and although I am very pro privacy, I had to eventually take it off due to all the extra hassle it created.

Don't know about slowing down. I am not seeing it. I feel differently about security.

Replacement phone via Uh-Oh, Can I use NANDROID backup?

I managed to somehow break my 3 week old HTC 10's rear camera glass so I'm going to get it replaced via the "Uh-Oh Protection" since I bought from HTC directly.
I have the Unlocked US edition, but use it on Verizon. When I get my replacement phone, I'll go through the steps to Unlock via HTC dev, run Sunshine for S-OFF and change the CID/MID to Verizon. At that point, can I just flash a NANDROID backup from my old device onto the new one to get my ROM / Apps / etc. back? Will there be any issues since it'll be different hardware? The NANDROID will contain everything I need so I won't need to first apply the VZW RUU right? I think I've done it before on previous HTC hardware but I want to check if it'll work before I try it. Will encryption be an issue?

Sounds good as long as correct firmware is also flashed

I don't see it being any issue.

So I just got my replacement phone. I followed the exact same steps as I did on my original HTC 10 to get s-off and convert to Verizon (used the same files as well). I made a fresh NANADROID backup on the old phone in TWRP, copied it over to the new phone, and restored it. When I reboot I get stuck on the white splash screen. I tried wiping the cache but I can't progress further.
I was really hoping I'd just be able to use the NANDROID so I don't have to go through the arduous process of backing up all of my apps and settings, and copying them over in TiBu, and having to recustomize everything in VenomHub/Xposed.
What am I doing wrong?

Try dirty flashing ROM

How would changing devices between TWRP backup/restore affect encryption?
EDIT: Since TWRP decrypts now, phone encryption would be a moot point in this context.

I received a replacement Uh-Oh phone from HTC. Unlocked bootloader, installed TWRP and S-Offed. Tried using my Nandroid to restore but TWRP would not see it (file names different, based on S/N). I created a small new backup to create the proper file structure and renamed the old Nandroid backup and placed it in the proper directory. Still would not work so I went to my TiBu backup and reset everything back up.
Here's a strange result though - my fingerprint works fine to unlock the phone but somewhere along the line (perhaps my attempt restoring Nandroid) the pattern lock changed. So now I cannot unlock phone using the pattern and cannot change it. I can use fingerprint so it works for now but I would like to reset the pattern lock - any ideas?

So when you did a restore with TWRP, what was the result? What does "still would not work" mean exactly? What did the log say?

I'll have to dig into the log file but it is my habit to only backup /data. That's what I was trying to restore. I might need to factory reset to get the pin reset I suppose. Was hoping there was a file I could delete to reset the encryption.

Just in case anyone has this issue of losing their pattern lock from a Nandroid restore I found the answer in a different thread. Use a file manager with root access such as Root Explorer, or use TWRP's file manager capability to delete the locksettings.* files in /data/system. Reboot and your device will no longer have a pattern lock. You will need to create a new pattern lock along with new fingerprint unlocks.

Factory reset erases everything, leaving nothing to decrypt.
Your idea of "reset encryption" would make encryption useless if anyone could just remove the lock without the PIN/password.

10. After I restored my Data backup and boot back to Android, I'm entering the correct PIN/password, but it's telling me the password is wrong. What happened, and how do I fix it?
It appears that sometimes after restoring a backup of Data where security was enabled (such as a PIN or password lock), the device does not recognize the correct password. There are two ways to avoid this issue:
Disable security in Android?*before?*making a backup of data.
After restoring Data, while still in TWRP, use the TWRP File Manager to navigate to /data/system and delete all the locksettings.* files (such as locksettings.db, etc). When you reboot, the password will be gone.

Is that referring to unlocking the screen or decrypting the device?
The question was referring to encryption.
When TWRP restores a backup, is it encrypted? (There's a few "it depends" to that question I would think.)

Bluetooth problem after flashing TWRP

Hi,
I flashed TWRP on my unlocked Redmi Note 8T with MIUI Global 12.5.5. Everything was great until I rebooted it and saw Bluetooth error which pops every time I try to turn Bluetooth on or just randomly during usage of the device. I also tried to re-flas TWRP with Orange fox but it unfortunatelly did not help. Now I have no idea what to do but there are also some other people with this problem (for example:
https://www.reddit.com/r/Xiaomi/comments/y9zsak
).
Does anybody know any solution? Thanks!
Btw Orange fox is for ginko devices, I did not find version for willow

I had the exact same problem when I tried to root my stock rom in ginkgo. I was getting a lot of "app keeps stopping" pop ups, and that also included bt. My bt was completely broken until I changed rom. Also I'm guessing this had happened when I had rooted my phone with magisk, not by flashing recovery itself. Perhaps you could try to uninstall magsik, and see it it resolves the issue for you. If that would be the case, then you would have found your problem, and maybe you can flash a custom rom to safely root your phone.

Thanks for reply, but i did not have magisk flashed on my phone. I only had installed the app, prepared apk file and did nothing in TWRP (Orange fox) , just flashed a recovery with my PC, checked that it is working and rebooted device. Anyway I tried to do it only because of acces to NFC and Gpay which is now blocked.
As you also said, I would like to try custom rom (like LineageOS) because it seems like bad idea to have a stock room on an unlocked phone. Only the problem is how to backup data like data from apps, games etc.
So now it tried one of my ideas, which was to install Magisk (root) and uninstall it but it also did not help (I expected that)

To backup data simply copy your personal files in pc or sdcard. And to backup data in apps, take back-up of only those apps and where you need to backup. Don't take a complete backup using some app. That consumes a lot of space and make the newly rom feel "not so new". Most apps don't require you to take back-up offline these days. I usually backup only my personal files before flashing rom.

Yeah, that's true. But don't you know how to backup data from these "offline" apps? I was trying to solve this also before unpocking bootloader like a year ago but unsuccessfuly.
Also, which rom should I choose? I'm deciding between LineageOS and Pixel experience.
So I have LOS installed but I can´t install other zip files (like Google apps). Im only getting error: signature verification failed while. Im using LOS recovery so where is the problem?
Solved it!

Hey @vasik006 ! I know this is very late and you might have found the solution yourself, but I found the solution to this problem. Since yesterday I was trying to root my ginkgo with twrp, using magisk delta and had exact same issue. Joyose and bluetooth keeps stopping, and don't work. Simply factory reset ( I also formatted data) in twrp, and in next boot bluetooth should work. Then you can simply install the magisk apk and let it do its thing. No need to flash again since it has already made changes to boot file that can't be overriden by resetting phone.

Thanks, this might help someone else with this problem. I have already formatted my phone, installed Lineage OS and everything is ok

For me, the problem with BT and Joyose occurs only with TWRP v3.7.x. I went back to TWRP v3.6.1_9-0 but now backups are not working.

I have the same problem with the Redmi note 8. Did you unroot first or did the factory reset directly? Tks

no need to unroot. simple factory reset the device and you're done.

TWRP is invaluable for backing up the system before making changes like theming etc. and I can take a TWRP backup to any of my (all the same) devices and restore the whole thing in just a few minutes. So convenient! I really couldn't imagine life without TWRP. TWRP enables me to clone my device in case of hardware failure. All my settings and all my apps and all my custom configurations which would otherwise take hours/days to setup - BAM! Presto! on the new device and running perfectly.
TWRP + NeoBackup are essential. TWRP as described, and NeoBackup to roll back breaking updates to apps when devs butcher them, break them, and/or just remove really useful features. I also disconnect apps that get ruined by an update from the Play Store so they don't keep coming up when I check for updates.

I would advise you to read the posts again. They were asking about how to take backup of "personal apps" which twrp can't do, and if they are changing ROM then twrp backup won't be of any use to them. Therefore, whatever you're trying to tell here doesn't really help the discussion.

TWRP does backup personal apps and their settings. Once you restore a TWRP backup, you have everything back except media files - images, videos, documents, etc. The launcher icons, the apps, the system settings - everything is a perfect clone which you can restore on a new device (same model, of course).
I actually came across this thread searching to see if others had a problem where merely flashing TWRP caused Bluetooth to crash (and Atmos).

Use OrangeFox

is there anyone use BT-fix-for-PE-20190618.zip to fix this problem ?

I'm on an ROG Phone II with the same issue.
The "fix" is to wipe in TWRP and install Magisk BEFORE you leave for your first boot and NEVER come back to TWRP as the issue will return the second recovery is booted.

From what I can tell, this is correct. 3.6_XX-X allows me to come and go from TWRP as much as I please without incurring the bug, however, I haven't tested backup though I can't see a reason why they wouldn't work.
Are these existing backups that aren't working or the whole backup function in general?

amazing, I have do nothing, just reboot my device, and yesterday the bluetooth also has problem, but today I open bluetooth, it is no problem. I'm still confused about that.

It seems to be a twrp issue. What version do you have? And what version of magisk do you have?
I have recently flashed miui 12 (android 10) after bricking the phone using qtel. I noticed the Bluetooth problem last week and didn't find a fix. I have twrp 3.6.2 and magisk 25.1. I had twrp 3.7.1 but if failed to decrypt data using pattern so I rolled back to 3.6.2. And I thought that magisk had to do with the Bluetooth problem so I rolled back to 25.1 from 26.
I still can't use the Bluetooth, and I don't have time to reset the phone, I just finished restoring everything

I CAN CONFIRM
go back to the previous twrp 3.6.2 version + wipe factory reset or simply format data solve sucesfuly solve installation issue of Magisk 26.1 or Magisk Delta 25210

I can't afford resetting my phone right now , don't have enough time. I'll let it like that for some months.
Edit : I have miui 12.0.6 installed (android 10) and I'm not planning to upgrade since I have much better battery life (even better than every mod I tried). I wander if I flash miui rom from recovery can fix it?
Edit 2: flashing the rom from recovery didn't fix it
