Hello guys,
I am running the latest 2.2.0-X OOS, with latest TWRP recovery, and rooted with supersu. The problem arised when decided to encrypt my device. Supersu and root stopped to work. I tried to reflash supersu binaries on TWRP, the installation is successfull, but when i boot my device still no root.
So to my conclusion Supersu app & root doesn't seem to work on an encrypted device. Any ideas or suggestions or workaround?
Thanks
You should be able to do it :/
When you encrypt a device, the only partition encrypted is the "data" partition not the "system" partition (where the root is made).

I figured out what the issue was: All you have to do is follow this guide:
http://forum.xda-developers.com/not...tSd7OU3zvjXIDCyXg&sig2=QqJIbUNvupVJnERW2w4K_w
* Note : This works on stock kernel, couldn't make root to work on encrypted device using boeffla kernel. don't know about blu_spark

is it everything in the firmware folder that says modem? my vs895 is on 24b and i want to back it up before downgrading
i wasnt sure if i needed to downgrade or have TWRP before using this method:

thanks, cory
Since that method is talking about flashing a zip file, then yes you have to have TWRP installed. These days TWRP's backup function can backup the EFS on it's own without flashing anything. I don't know anything further about the EFS.
Use @bender_007 's autorec app, available in the General section of the non-variant specific G3 sections to install TWRP. Use the one specifically indicated for 24B. This is assuming you're already rooted. Then from the TWPR the autorec app installed, flash the latest TWRP v2.8.7.0, and reboot recovery. Click Backup and choose EFS. Move the backup to the MicroSD card and if it were me I'd put it in a secondary location too, since downgrading properly will erase your internal storage.

it looks like with this i wont need to downgrade at all. i was only going to downgrade to get twrp and install cm12
Hi,
I have an unlocked bootloader on the XT1521, with TWRP and Cyanogenmod 13.0 installed. I just updated CM via OTG, which worked correctly, but all Google Apps were removed. When I tried to flash them afterwards, nothing happened.
So I went on and wanted to wipe /system to reinstall CM and GAppsbut apparently, my /system partition is "busy" and cannot be unmounted. I get this error all the time, regardless if I try to a) uncheck the "mount system partition read-only" and swipe to allow modifications, b) try to unmount it manually via the mount menu, c) try to wipe it (the "repair" option is not available for \system unlike for /data, e.g.), d) try to flash CM13.0 zip. The error message is always like "failed to unmount '/system' (Device or resource busy)" and, oddly, I did not find any similar issue via Google, as it is not just a "read-only"-related problem.
Does anybody have a solution to that issue? Thanks!
Alex

Hey i had this issue and finally pinned it down to the TWRP I was using. It turns Official TWRP has this issue. This can easily be resolved if u flash Squid's TWRP
Download the latest version from here:
http://forum.xda-developers.com/devdb/project/?id=10398#downloads
That was the problem apparently. Thank you!
Thank you! I was having this problem as well and that fixed it.
Thanks very much for your help!!!
I was scared of loosing my phone...
Thanks.
I have a US Cellular XT1526 and was unable to install GApps on CM13 without this. CM13 installed fine, and GApps looked like it installed, but on reboot nothing was there; GApps failed to install. Using Squid's TWRP fixed it; thanks!

thank you so much :d
thank you buddy.....
my mother is using Motorola E 2nd gen LTE and i flashed it with cyanogenmod 13 used officialTWRP recovery... and i faced the same problem. thank you very much for your answer and also the other guy for asking the question.
Should I select boot or recovery as partition when flashing this img
cannot restore system mounted read only
I have a LG G5 H850, with 6.0.1 and stock V10c-EUR-xx.
I disabled disk encryption using the no-verity-opt-encrypt.zip utility by jcadduono.
Now I wiped again using TWRP, but encryption is still disabled as the boot.img/partition still has his modifications to the fstab files (where he does
the change s/\bforceencrypt=/encryptable=/g etc.)
How to I set that back to as it was?
I got into this sitation as I kept finding TWRP could not access the partition - asked for password and there was none.
I do want to use encryption but in my first hour of setting up the phone I had a problem where when I booted into TWRP it would ask for a password and it was not "default_password", and I had not set anything and never used lock screen/pin etc. I tried setting a lock screen/boot screen password - the phone worked but TWRP could not access the filesystem. I tried the cryptfs application and still TWRP was not able to decrypt/access the partition.
Then I tried a terminal with vdc cryptfs changepw command and that just locked me out of the phone completely, as the new or old boot password would not work.
So I went for the no-verity-opt-encrypt.zip solution - but I dont want an unencrypted phone either. Now I want to try encryption and TWRP again - this time setting a pin at the first setup screen opportunity to see if that gets set as the password that TWRP could use. However I can't remove the disable encryption patch!
Ideally I am trying to get to a setup where:
encryption is enabled
I want to be able to boot TWRP and access the encrypted filesystem and install more zip files such as xposed/supersu updates etc anytime in the future.
I dont want to use the "no-verity-opt-encrypt.zip" patch.
I do not want TWRP to be locked out from modifying the encrypted system partition.
Additionally, I havbe not been able to install xposed using TWRP and the zip file (http://dl-xda.xposed.info/framework/sdk23/arm64/xposed-v86-sdk23-arm64.zip) .
In TWRP it installs, I dont see any errors, but on boot up I have no xposed icon. I have been able to install it by downloading the apk and installing as an untrusted source, not sure if there is something wrong in having to do it this way?
Thanks.
current TWRP build for G5 doesn't support encryption
you can use encryption but in TWRP you won't be able to access some partitions (if I remember right is data partition but I might be wrong here)
in order to do so, you need to restore base firmware with LGUP that will turn encryption back on
Thanks. I got it working by flashing just the boot using LG-H85010C-Flashable.Boot.zip

may i ask how did you root it after that? because everytime i try to rooted while encrypted,i flash the zip in twrp (with no errors) but system still has no root! the only way i could root was to format /data in twrp, hence have a decrypted phone!
I am looking for the same thing as you are : encrypted phone with twrp and root access.
I rooted using TWRP adding supersu at the time of installing the OS before the OS encrypts the partition. Once the partition is encrypted TWRP can no longer access it, and I can no longer install supersu or anything else.
I may have installed root before encrypting, then reflashed the boot partition so that encryption is re-enabled, then ran twrp to reapply supersu - which would fail to put files on the encrypted partition - but this is fine as they were already there, and let the twrsp supersu installation modify the boot partition.
The result is an encrypted phone with root and TWRP. However, TWRP can not access the encrypted partition so I don't think I can update supersu using TWRP, and I dont think I can patch the OS easily without wiping the encrypted data and reinstalling everything due to this. As I am not sure if updating the OS works without wiping data, I have yet to try that.
you shouldnt have to mess with data at all to use supersu while encrypted.
my g5 is encrypted and always has been (besides in various testing) and there's never been an issue of flashing supersu.
though there may be some issues if trying to restore encryption and flashing supersu in the same reboot cycle.
and yes, data partition in twrp cant be accessed in twrp if encrypted.. but you can just push a file to the /tmp directory while in twrp and then flash anything... or enable adb sideload and flash something that way... or use an external sd card and put the file on there. the only thing you really miss out of if using twrp while encrypted is being able to manipulate the data partition... it does not stop you from flashing files or running scripts that modify /system or other partitions (besides /data).
supersu uses the unencrypted /cache/ partition to work in when you flash it while encrypted so an encrypted /data partition should not be relevant.
My bootloader is unlocked and Twrp is installed. I flashed CM13 but was having issues with root so I ran "adb shell reboot disemmcwp" that made Adaway work but Titanium backup still would not uninstall system apps. Twrp says it can't dycrypt data and I am unable to move my TWRP backup off the device. I've formatted everything. I don't entirely understand the encryption, if I need encryption? Should I be having errors in Twrp or be able to mount system? I don't know if I did something wrong and what to do to fix it? I was hoping to figure this out before reflashing cm13.
mod please move to questions, sry
Not sure if this will fix your problem but I had the encryption issue when I flashed CM. When I set up my pin I unknowingly chose ask for pin when starting device. So TWRP asked for a password to decrypt. My pin did work in TWRP. I fixed it in the security settings. Does TWRP ask for a password?
Fixed it. I had choose a pin setting up CM. The fix for me was to hit cancel in Twrp when it asked for a pinand then format the data.
After the latest magisk update 20.0, twrp (3.3.1-0) asks to Swipe to allow modification or keep read only. I always choose swipe to allow modification as that's what you primarily install twrp for, but even after doing so twrp fails to read my internal memory. Before this magisk update it didn't ever ask me this, except for the first time i installed twrp. Just shows 0MB and fails to mount storage for backing up or repair (Repair file system gives an error code 8).
Now the thing is that everything was working perfectly fine until this latest magisk update. Rom works fine (Havoc OS v2. 5), magisk works fine, root works fine, phone is encrypted just as it was before, everything is fine except twrp and i really need twrp to keep working as it was before.
Now yes, I have removed pin/password and tried to make twrp work, switched from pattern to pin as some solutions out there say that twrp will ask for the pin on boot up and on entering the correct pin it will decrypt the internal storage and all will be fine. But no, it didn't work.
Whatever it is am damn sure its magisk. Rom is the same, kernel is what came with the rom, no magisk modules installed, infact I run magisk in core mode only (yes I have disabled core mode only to see if it fixes the problem). I have attached a screen shot of magisk home screen and you can see that under the advanced settings Force encryption is enabled (just like it was enabled while installing magisk for the first time, I have never messed with those settings) and the other two are disabled. Do i need to check that recovery mode? Whatever the solution is, it is preferable that I don't loose my rom and data. But if there's a 100% working solution which involves wiping everything then please mention that too.
Also some solutions need you to change the file format of the internal storage, and I am a little afraid to try that.
Sorry for the extra long post, Thanks in advance.

Check your TWRP logs. They will contain clues as to what might be the problem. Then post the logs in your TWRP forum. You can get the logs via adb
Code:
adb pull /tmp/recovery.log
adb pull /tmp/dmesg.log
Did you try changing the storage type? That helped me once. Also what helped was using the latest or an older version of twrp, you can also try doing this. Let me know what happens.

Changing the storage type would be safer or flashing the same version of twrp on top of it (as I have the latest one) or an older version would be better? I will use the official twrp app for the later.

Try using an older version of twrp first. Changing storage type for system or data might lead to data lose. Make a backup in any case.
