TWRP can't decrypt /data on CM12.1

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.

Recover data after unsuccessful force encryption

I am in trouble of loosing all my userdata after following the below process:
1. I was on stable 4.5.1 and not encrypted.
2. flashed blue_spark 8.52 recovery.
3. Reboot to recovery and full wiped (except user data).
4. Flashed OOS beta 18 and Magisk 14.3.
5. Rebooted and waited for 20 min but was still on rebooting process.
6. Force rebooted to recovery and alas!, twrp asking for decrypt password!!!
7. Reboot to system and message appears as 'Encryption Unseccessful'
I am not been able to access any partition including userdata from TWRP (as it's asking password), OOS also not booted as well.
Now I will be grateful if someone have any knowledge to skip TWRP password and provide access to userdata to recovery/copy data (photos/files etc) from the device before format userdata and start over again.

If your data was previously decrypted then disable encryption, format data, install a ROM that does not enforce encryption, then try looking on the Play Store for photo recovery apps.
Note that it will not be possible to recover data from the encrypted part of the device. If you left it running for 20 minutes, the chances are your data is almost entirely gone at this point.

Like stated above, your data is probably destroyed since you interrupted the encryption process.
Have you tried "default_password" as the password in TWRP?

Flashing /system not working

Hey guys,
I followed a guide I found to root my G6 (ALI): https://forum.xda-developers.com/moto-g6/how-to/guide-twrp-root-magisk-installation-t3816569 and now have an unlocked bootloader, magisk installed and TWRP as my recovery.
I have flashed TWRP to recovery on my g6. Whenever I try to flash a custom system image I made (I wipe cache and data), or modify /system in TWRP, everything looks fine in the TWRP file manager. However, when I go to boot my phone it takes longer than usual to boot, encrypts my files and all the changes I made are undone.
The only thing that has successfully modified /system was the magisk manager when it patched my boot image.
What is going on?
Thanks.

Oneplus 3T Restore Issue after Pie Update - HELP

So, quick explanation. Pie update showed up on my OP3T and I have an unlocked bootloader, TWRP 3.3.0-1 and Magisk 18.1 on OOS 5.0.8 (Oreo). Additionally I had a second user account and a Work Profile on my main account.
After reading on the decryption issues (and against my better judgement), I decided that maybe it could work through System Updates since it detected root and was going to install the full package. Big mistake. Got a "Decryption unsuccessful" and sadness.
I had of course taken a full TWRP backup to be safe.
I'm going to put the detailed explanation below (hidden) because it's quite long.
Now in more details. Along with the TWRP back up, I had an oandbackup -backup- of all apps (main and secondary account, but not work) and manually copied all internal storage files on my PC. After the "Decryption unsuccessful" message, I pressed the "Reset Phone" button (probably a stupid decision) thinking I'm good since I have a backup. Phone rebooted, with TWRP replaced (as expected), and I'm in the new OS. Played around a bit in Pie [added my account, registered a fingerprint and PIN, connected to WiFi and checked a few apps] and then I thought, "ok, time to go back", and then it happened.
I rebooted the device and it asked for password to boot (which was the PIN I added in the OS), and then rebooted again in Fastboot to flash TWRP again in order to restore the backup.
TWRP flashed successfully and I copied over my backup. Restored System, Data and Boot, wiped Dalvik & Cache, rebooted, shows the Oneplus logo, gets stuck for a bit and then goes to Fastboot. Ok...probably messed up somewhere, let's try again. Same thing.
I guess the notion that I had the TWRP backup made me feel safe, because I continued to experiment.
After a full 24hours awake trying to restore my phone to its previous state, I have the following:
Restoring System, Data and Boot results in the device booting and showing the Oneplus logo and then after a few seconds, going to Fastboot.
Restoring EFS, Recovery and/or Cache makes no apparent difference.
Restoring Data and Boot, but System Image instead of System makes the device boot and start a lengthy process (possibly of encrypting the entire Data partition) lasting about 2hours, during which the device becomes hot enough (~45C / ~113F) that holding it for more than a couple of seconds is very uncomfortable. After it finishes the lockscreen has my wallpaper, app notifications (like VPN) show up and the second account is there, however my old PINs for either accounts don't work and the Data partition can no longer be accessed in TWRP
Code:
Data successfully decrypted, new block device: '/dev/block/dm-0'
Updating partition details...
...done
[COLOR="red"]Unable to mount storage[/COLOR]
Successfully decrypted with default password.
Updating partition details...
...done
[COLOR="red"]Unable to mount storage
Failed to mount '/data' (No such file or directory)[/COLOR]
Full SELinux support is present.
[COLOR="Red"]Unable to mount /data/media/TWRP/.twrps[/COLOR]
MTP Enabled
When Data is inaccessible in TWRP, only formatting it can bring it back (empty, of course). And then it needs to be formated to F2FS again as well (Oneplus uses F2FS for the Data partition).
Flashing the Oxygen OS 5.0.8 zip file after restoring System works the same as restoring with System Image.
The closest I've come to restoring my device to how it was before is either:
Restoring System, Data and Boot , in which case booting ends up in Fastboot.
OR
Restoring Data and Boot, and System Image, and then not being able to login (plus, no access to Data from TWRP).
I have literally no idea what else to do. If anyone has any idea or suggestion, it would be greatly appreciated.
I'd rather wait for some suggestions before trying to flash other zip files that deal with encryption, since I never had to do that when I first rooted with Magisk.
------------------------------------------------------------------------------
How the device is supposed to be:
Bootloader unlocked
TWRP Recovery 3.3.0-1
OxygenOS 5.0.8 (Oreo)
Magisk 18.1
Main user account
Secondary user account
Work Profile (with Shelter) on Main user account
What I have available:
Full TWRP backup of all partitions [Data, System, Cache. System Image, EFS, Recovery, Boot]
oandbackup backups of Main & Secondary user accounts (apps and APKs)
Manual file backup of Main user account's Internal Storage
All OxygenOS Oreo zip files that Oneplus was releasing over time
TWRP images (3.2.1-0 and up)
Stock OxygenOS recovery (they used to have it available)
Magisk Installer/Uninstaller/Manager APK
Time on my hands
Sleep deprivation points
Enough will to live

Problem updating custom ROM - TWRP won't decrypt data

After trying to update to a newer version of a custom rom, crDroid 6.4, I can no longer boot into the system. The phone only boots into recovery. TWRP no longer asks for a password in order to decrypt the phone, as it has done before. I have tried wiping Data, Cache, and Dalvik, and flashed the rom again, with no luck. Is it a way for me to force decrytion or something?
Any help is much appreciated! I am new to this, and still learning.

I assume that the data partition is actually still encrypted and you see random folder names in TWRP. If so, try formatting data in TWRP (not wipe, but format) then reboot to the ROM.

Will this delete all my files?
Also, I'm not sure if I am flashing the ROM correctly. I have the ROM, magisk and other files on my computer. I use "ADB Sideload" under advanced in TWRP and "adb sideload romname.zip" on my computer.

Yes it will delete all your files. If you boot to TWRP and it doesn't ask for the PIN, etc., but you see all your folders have random encrypted names, then everything is lost anyway. There is nothing you can do to recover that data.
In future just copy the ROMs onto the phone and flash them directly off the phone in TWRP, using the install menu.

Thanks for your help. Luckily I had backed up all my photos. I am up and running with a new rom. I am testing omni rom as it now comes with microg prebuild.
