I just decided to move to CM12.1 on my Droid Turbo (XT1254) after the 1/27 Snapshot (YOG7DAO3J1) was posted. I am running this with TWRP 2.8.7.0, BHB27 Kernel, and OpenGAPPS 5.1. So far, almost everything has been fantastic and the performance of the device is like night and day compared to the Verizon software.
My problem is that the CM12.1 ROM has my device encrypted to begin with, which is nice but giving me trouble. I can't get into TWRP to install Xposed framework or other .zips via ADB. I have tried the following:
Disabling require password on startup
Changing the password in Android
Changing the password from root ADB shell
Using a pin
Trying "default_password"
Can anyone give me a solution or some advice? Any help is greatly appreciated!
Having same issue with TWRP not recognizing any decryption password given... Any ideas out there? Is TWRP incompatible with Droid Turbo HW Encryption, or ?

This thread is kinda old and I assumed nobody really knew what was going on with it either. I ended up just not using the encryption. The first time around mine was encrypted without me knowing, which was the issue. I just wiped all partitions and flashed the ROM again...
I am having a similar issue so i thought i would chime in, despite the older thread. I had a stock ROM that was encrypted and I was able to unlock and root with SunShine fine. Flashed on TWRP 2.8.7 and ran into a "Unable to mount storage. Failed to decrypt data" error. Updated to TWRP 3.0.0 and still have the same issue. Still working through a resolution as the phone is still functional if I just boot normally. When you mentioned you wiped all partitions, what process did you use? If i can just get access to the interal storage I can flash a ROM and be good to go.

So far, the only way I have been able to get encryption working with CM12.1 on the Droid Turbo is to do the folllowing (Note: This assumes you have bootloader unlocked and TWRP installed as your recovery):
Part 0: Make sure you have what you need
1. Stock Droid Turbo Firmware SU4TL for your device
2. The version of CyanogenMod 12.1 that you need. I recommend a Snapshot, but it's up to you.
3. TWRP 3.0.0 or later for your Droid Turbo.
Part 1: Final set up (Yes, we do this first)
1. Download CM12.1 & Download OpenGapps arm for 5.1
2. Wipe device (system, data, cache, internal storage), copy CM12 install zip and opengapps install zip via USB to device.
3. Flash CM12 and OpenGapps in TWRP
4. Set up device how you want it to be (install your apps, set up your accounts, etc).
5. Set whatever lock-screen PIN / Password / Pattern you are going to want on your phone in general!
6. Make a Nandroid backup of your 100% set up phone in TWRP
7. Copy your backup TWRP folder to your PC.
Part 2: Encrypt device and put everything back how we want it.
1. Flash stock Verizon firmware (SU4TL) via Fastboot. Do not flash stock Recovery, but put back TWRP if you did somehow (I use a simple bash script I have attached below).
2. Boot device, go through initial set up, don't download apps (we're going to be wiping the device soon).
3. Make sure your battery is 80%+ charged, and your device is plugged in.
4. Set a password or PIN on your phone.
5. Encrypt your device (this will be fairly fast, as /data is empty, but you should be asked for your encryption password on boot.)
6. Reboot to recovery. TWRP will ask you for your password to decrypt. It should work with no problem.
7. Copy your backed-up TWRP folder with your CM12 install to your device via USB. The TWRP folder goes in the Internal Storage root directory.
8. Still in TWRP (Do not reboot), go to Restore, and select the backup you just copied over. This will replace the stock rom with your CM12 backup.
9. Your CM12 install will be restored, but your device will remain Encrypted.
10. Reboot into CM12. Win.
You will need to decrypt your device every boot with the password that you selected when you initially encrypted your device. Your lock-screen password CAN BE DIFFERENT. That is why I do it this way. I have a fairly long password to decrypt my device on boot-up, but a pattern as my lock screen. That way I can quickly get into my phone during daily use without having to constantly type in a fairly complicated password.
Previously I installed omnirom and set a screen pattern now when I rolled back to oxygen OS 5.0.2 I set a different pattern but secure boot pattern is still the old one I've Used in omnirom, I wanted to install new version of that rom now and when i Did reboot TWRP won't decrypt data with my present pattern.
Can someone help me bypass and decrypt the data, I've my important files in it.
With this bug I've to format my data to use my phone but I want my data, help me out.
Have you tried to decrypt data with another TWRP, like BluSpark or acuicultor?
Is there any TWRP for P9 EMUI8 which supports Encryption and Decryption ?

There is no TWRP properly supporting Chinese Oreo encryption on P9 in a way that:
- you don't need to format Data and make changes to Vendor partition
- you just need to enter your Android unlock pin/pass whenever you boot to TWRP
- with that that TWRP can properly read/write to Data and Internal memory
However, there is a Chinese TWRP (language can be switched to English) that you can for one time remove encryption from Data (it is not enough to format Data but it must be also edited an fstab file on Vendor partition)
After that encryption is removed and you can fully use TWRP for e.g. Nandroid backups, installations from Internal memory, installations to Data partition, editing on Data partition (in case of e.g. bootloops with Magic modules), etc.
Also, once encryption was removed you can switch back to your preferred TWRP from that Chinese TWRP (that TWRP has some other issues)
It was long ago couple of us experimented with, you can start from the following post and follow the links (but always compare the dates, newer posts from the same pearson mean they were written with more experience and understanding of the matter):
https://forum.xda-developers.com/showpost.php?p=80029346&postcount=1843
Good thing is that (once you don't want it anymore), stock Oreo can be fully reinstalled and encryption reinstated. E.g., eventually I did it on two my P9s (almost a year ago), but I was no more updating the posts about
Of course, once Data is decrypted, it can be also used for TWRP when working with GSI/AOSP ROMs (not only with stock Oreo)
Hi!
My only encounter with rooting was several years back when it used to be a simple affair (one click rooting app based on exploits like framaroot etc), so please bear with me.
I'm on Stock Oreo 8.1 (Patch 1 Aug 2019) Sanders 1804 (India) version. I've followed various guides and have been successful in flashing TWRP 3.4.0 (Official Sanders version) and Magisk 20.4. But everytime the phone is rebooted, TWRP can't mount internal storage and shows 0mb.
I tried all three methods I could find:
1. dm-verity zip flashing - Log said fstab not found. Searched and found that from Oreo, Android's encryption approach has been changed. I couldn't make much sense out of those, though.
2. Manually replacing the `forceencrypt` to `encryptable` then flash stock recovery and format data. Didn't work.
3. Formatting data right after TWRP is flashed. Didn't work either.
The maximum it works is for one time when I can connect the device to laptop to add some zips to it to flash. It doesn't make sense to wipe the data when it's the data only that we want to back!
My purpose is to make flashable zip (nandroid) to revert to if anything goes wrong. It was phone's wifi frequent disconnection (or connected but no internet) issue which forced me to try root. I'm not much interested in new ROMs and am fine with stock itself but need a backup of all apps with data etc. Also, I couldn't understand clearly the FAQ on TWRP website that says TWRP doesn't backup internal storage but backup data. As I don't use SdCard, the internal storage is mounted in /sdcard folder only
I'll really appreciate if someone can help me.
Thanks
Found solution from a helpful guy in a Telegram group.
1. Use ONLY attached zip/img files and follow exact same order.
2. Flash TWRP, reboot to recovery
3. In Wipe section, choose Format data, type YES and confirm. Reboot to recovery again.
4. Flash DM-Verity-ForceEncrypt.zip file. Flash Magisk.zip file. Reboot to recovery.
5. (Optional) Make a backup if you want or Reboot to system. Done!

Bugs
-Userdata decryption is not working. You can flash multi disabler (check this before flashing) to disable encryption or use an external SD or USB OTG for putting ZIPs and IMGs on it in order to flash them
- Data backup is not working due to device encryption
How to Install
0. READ F.A.Q section first here
1. Unlock your bootloader
2. Boot to Odin mode
3. Check AP box and select TWRP tar file

F.A.Q:
What is data encryption and why doesn't it work on TWRP?
Samsung M51 uses file-based encryption that encrypts the user data partition.
By default, TWRP can't decrypt user data partition, which makes it impossible for us to access the internal device storage from TWRP or recovery MTP, which means you can't put ROM files on your internal phone storage and flash them from there.
What is Multi disabler and how does it affect your phone?
- Multi disabler disables and removes the encryption on the data partition, which makes it possible for you to access your internal storage from TWRP or recovery MTP. thus, making it possible for you to flash files from internal storage.
- Removing the encryption on your device's internal storage makes it possible for you to access your files from recovery directly, which makes it possible for anyone to access your private files without your permission from recovery.
- All of the above means that your device will be less secure. So if you care about device encryption then don't flash the multi disabler and use a USB OTG or a sdcard to flash ROMs, which I recommend. Otherwise, flash the multi disabler at your own risk!!!
- FLASHINF MULTI DISABLER REQUIRES PERFORMING A FULL DATA WIPE WHICH MEANS YOU WILL LOSE YOUR DATA. SO BACKUP YOUR DATA BEFORE FLASHING IT.
My device keeps rebooting to recovery after flashing TWRP, why?
Most probably you will need to wipe your data partition and flash multidisabler
Data backup is not working even after flashing multidisabller, why?
Current multidisabler still can't fully disable FBE encryption, which means that TWRP can't read data partition at all, hence creating backups will always fail.
Reserved just in case
Thank you so much for your efforts,
Does backup, restore, work smoothly in this version of twrp? Does it fully restore after making a backup? Or are there still mistakes?
In Twrp 3.4.0 Data backup is not loading. Nonoperating. But the system is loading.
Oh, thank you, thank you.

Currently I have no working ROM so I can't test back and restore functionality. But backing data should be working.. don't take that for granted tho..
It would be great if you can test that and report if it's working or not, or wait until I or someone else test that.
thank you for your efforts. i installed this twrp and flashed mutlidisabler. also formatted data before reboot. Unfortunately twrp does not allow to create backups. Cannot unmount system partition etc...Your android 10 TWRP version is creating and restoring backups allright. So for now have to continue using android 10!

backups will not work because of device encryption. Even after flashing mutldisabler, the device will keep encrypting the data.

Do you think that Magisk prerooting prior to TWRP flash might help here?
Or maybe we should just for full official Android 11 twrp release...
TeamWin updates TWRP to 3.5.1, Android 11 support coming soon
They're calling it a 'mini release' with a few notable feature improvements

Fyi -i have spare m51 device with android 11 installed. Ready to use it for any kind of twrp test builds. This is a good phone and we must have twrp for android 11 developed here. Thanks

prerooting won't solve encryption issues. Maybe when TWRP can be build using android 11, we can fix encryption issues or at least partially fix it.

anyways, backups will fail because of data encryption
Does this TWRP require to format data after installing without Multi disabler?

Nope, but you may need to install multidisabler to prevent the phone from reverting back to stock recovery. Don't formate the data after flashing Multidisabler and see if the phone boots or not

well i already tested that twrp build and it does not allow to create backup (which is the main reason i need twrp to start with). i will test your lineage roms no problem. Do you think that twrp will work properly with lineage 18?
