TWRP: persistent decryption of /data - Moto G5S Plus Questions & Answers

Hello and thanx for your attention. Can't fix my problem. Or I read the wrong threads. Anyway, i would appreciate your help.
Installed twrp r20, rebooted in recovery, flashed magisk 19.1 or su 2.82. First everything's fine, twrp's backup shows some Mb in /data (caused by magisk or su). So decryption is working at that point. Then, after booting into system and doing some settings, root is still there (rootchecker), but back to twrp there will be /data again with 0MB.
As i understand booting re-encrypts /data from f2fs to emmc. Anyone a hint? Main purpose of twrp for me is taking backups (before trying custom roms)
Running stock oreo 8.1.0 Europe with 01.02.19 sec patches
Thanx in advance

Found solution. Maybe it's for interest of TWRP newbies like me...
TWRP decrypts just in time, if you use the PIN of your android's LOCK SCREEN (settings-safety) at start. You will see full /data and can run a nandroid backup. Rebooting to system then will encrypt /data again.
A had issues using a password for lock screen, so better use PIN.

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.

TWRP - E:failed to mount /system (Invalid argument ) - but OOS still boots fine.

I just restored a TWRP backup which seemed to work properly
(OS boots and works as normal) but in TWRP I can't mount system
from the mount menu and when I try to reboot it warns me - no
OS installed, I'd understand if it wouldn't boot but it does, do I
need to wipe like a TWRP cache or something?

I already had supersu installed and ive just reflashed the kernel which made no difference apart from tripping dm-verity again (ugh).
Any other ideas?
Create a backup if you didn't. Wipe System (only system nothing else), then click on repair FAT. Mount system check box should be ok now...then restore System (only system) from your backup.
One question. Is it for the encryption system? Does it decrypt it?

Correct root and TWRP recovery for OOS 4.1.6 on OP3T - please.

I've been all over the OP3T forums looking for current information about the correct versions of TWRP and (Magisk or SuperSU) to use with stock OOS 4.1.6. I kept my old TWRP 3.0.4-1 and when I tried to apply SuperSU 2.79 SR3 I got an unusable system and had to restore from nandroid backup. I updated to TWRP 3.1.1-2 as per the Official TWRP app and now every time I try to reboot to system from TWRP it warns "No OS installed", but the reboot works fine. I have Magisk 13.2 ready to install but I'm reluctant until I know I have the right combination - the TWRP 3.1.1-2 backup is missing some partitions and I want to make sure I can at least recover my system if Magisk screws things up.
I've been all over the forums and all the relevant threads were closed months ago, or are written about OOS 4.0.3 or 4.1.1, or describes some hideous way someone turned their 3T into a pile of molten lava. Is there any current information about what combination of TWRP and a root zip will work with the latest OOS 4.1.6? Everything is stock except the unlocked bootloader. I don't want to flash a different ROM, I don't care about passing SafetyNet, I just want to root and go on with my life.
A couple of numbers is all I ask. I can't be the only one. Please - I've been without root for a week and it's bugging me.
TWRP 3.1.1-2 has got at least one major bug where it reports the OP3T as a OP3. That'll mess up your OP3T specific installations... Don't know if there are any other bugs, since I'm staying on 3.1.1-0 until they fix that bug. You also have the option of using blu_spark's TWRP. I've never tried it, but many users swears by it.
What works for me:
OOS 4.1.6
Franco Kernel r25
TWRP 3.1.1-0 (official)
Magisk v13.2
Magisk Manager 5.0.6
No issues whatsoever (for me)...
Thanks for that. I'd rather not change kernels, though. How likely is it that the same combination works with the stock kernel? Does anyone have that running?
OK, I tried it. Swiped the Magisk 13.2 zipfile in TWRP. The script ran partway through and then said "Can't mount system" in red letters. Now the phone boots into OOS, Magisk Manager is there and says "Rooted but no root permissions, not allowed?" It has reported several times that it needs to update, to the same version of Magisk and Manager that are already there. I allowed it to go through the cycle and reboot, with no change to behavior. When I try to run an app that needs root I get the permissions screen, but when I grant I get the dialog that says "Rooted Android required" - Either the su binary could not be found or you did not allow root permission..."
So, the phone works fine but unprivileged as before. I'd like to try clearing the cache, but since TWRP still reports no OS found (3.1.1-0 does this, just like -2) I don't really want to write into a system the recovery can't see. Besides, the existence of the su binary doesn't seem like something a cache clear will fix.
Advice?

Scratch that request. Things seem to be turning around - su works in terminal emulator, lets me ls privileged directories like /data. Root Explorer is working again. The only thing that isn't is AdAway, which can't write the hosts file. Otherwise the system seems to be rooted and working OK.
I'm still nervous that TWRP can't see that there's an OS on the phone, and I haven't seen any other reports of this.
It looks like Magisk can't mount /system read-write. Adaway won't install, and neither will Busybox. Titanium Backup also reports problems. I tried installing Busybox and the installation failed when it tried to remount system /rw.
Will look for solutions to this problem and report back here.
I've found many solutions to this problem, like installing busybox (Stericson Busybox apparently doesn't work in OOS 4.1.6, tried two others. Problem is, busybox will only install into a partition on /system, which requires that /system be read/write.
When I have issues with mounting system or anything like that, I go mount system myself in TWRP and it usually starts working after I reboot....I don't know why, it just works for me....if I see that error, that's the first place I go, everytime...

That won't work either. When I go to the Mount page in TWRP I can't get the checkbox next to /system to check. It just stays empty.

I seem to remember having that problem once before.... Can't recall what I did, I think it involved something with the terminal... I'm not at my desk right now, I'll look into it shortly and see if I can remember
Problem solved. The more I looked at the symptoms, the more I realized that the OTA I took after unrooting with SuperSU corrupted the system partition somehow. The first time I tried applying the OTA with the stock recovery it failed, but I was able to reboot and apply 4.1.6. That's when the trouble began - I was unable to reapply SuperSU. Fortunately I had done a nandroid backup between the upgrade and the attempt to re-root, and after the SuperSU script failed I was able to restore the backup (made and restored using TWRP 3.0.4-1) and continue working. It was either at that point or earlier, during the OTA itself, that /system was damaged - not badly enough to prevent the phone from working perfectly well, but enough to keep TWRP from mounting /system read/write. From that point on I was doomed. None of my other attempts to fix the problem had a chance as long as TWRP was restricted to mounting /system read-only. Then it got worse.
After a semi-failed attempt to install Magisk (rooted applications worked as long as they didn't try writing to /system) I restored my pre-root 4.1.6 backup one more time. After that, TWRP wouldn't mount /system at all, which prevented me from making any more nandroid backups.
It was time to act. I could keep using the phone unrooted, but the longer I went on the more work would be required to put things completely right. The risk would increase because I couldn't take any more snapshots of the phone to fall back to if I munged the device again. I also had a positive reason to fix things - during the two days the phone was rooted but couldn't access /system, Titanium Backup kicked in and did a full backup of all my software and settings.
With a damaged file system and full backups, there was no reason for halfway measures. I copied all my user data off the phone and used LloydSmallwood's unbrick tool to flash the phone back to its original OOS 3.5.4 state. That took care of rebuilding all file structures. As soon as I rebooted, OOS upgraded to 4.1.6 in one step, taking care of the system upgrade. Unlocked the bootloader, installed TWRP 3.1.1-0 (not 3.1.1-2, which has a serious bug for the 3T as someone posted above). I was able to mount and unmount /system from TWRP's mount screen, no problem. Ran Magisk 13.3 script without a problem, installed Titanium Backup, and tested an app restore. No problem. I'm now in the midst of copying all my stuff back onto the phone, after which I'll restore all missing apps and be back in business (I hope).
It's possible I could have done something tricky like reformatting /system and restoring the partition from my last good nandroid backup. But I always would have been concerned that problems would have popped up later, maybe during the Android O upgrade, when it would be way too late to recover my then-current setup. After seeing virtually every combination of working and non-working features, it just made sense to build from a clean system.
So thanks have been given to LloydSmallwood for his absolutely indispensable unbrick tool (this is the second time it has saved my phone). I should also thank my Galaxy S3, running the current build of LineageOS, which has gotten me through the two days it took to set my OnePlus straight. The Galaxy has performed better than a five year old phone running brand-new software should ever be expected to - if it supported LTE I could consider using it as a daily driver. This has been an education, and a reminder of how important it is to keep good backups at every step throughout an upgrade - and routinely during production use.
Thanks to all who gave advice in this thread.

[HELP] [URGENT] ONLY OxygenOS not Booting up !!!!

Hi guys
I am having a weird issue , I am able to flash ANY custom ROM ( mark my words "any") be it skydragon os, havoc os, lineage os but I am unable to flash OxygenOS (tried 5.0.7 and 5.0.8) . When I start the first boot after flashing the OOS zip file, it always get stuck on boot animation and the animation goes on forever. Please Help !!!!!
Note:
- Have tried with different versions of TWRP but no success
- Always Did a clean install
- When after being stuck at boot animation for 40 mins , i FORCE restarted my phone to recovery and found that all system files and folders have been made as normally so i think there was no error in flashing process but still ROM not booting up.
Also:
- If someone has successfully booted the latest OOS from scratch ( I mean clean install) so please can you provide your ( links !)
1. TWRP file
2. OOS zip file

If you're coming from a decrypted data partition and then flash stock OOS and nothing else, it will re-encrypt your data. This could take a long time.
I recently did some testing of TWRP for fixing formatting and decryption (see https://forum.xda-developers.com/on...al-twrp-touch-recovery-t3742894/post78339714) and I did a totally clean install of OOS including formatting the data partition.
I used a TWRP version from this post https://forum.xda-developers.com/on...al-twrp-touch-recovery-t3742894/post78332159. The one I used is the very last one which is described as:
-----update2

Exactly How Much Time can the re-encryption process could take?? Cause I gave it good 1 hour
Also to make sure i am getting it right , you mean to say that i should use the TWRP file you mentioned below your statement
"-------update 2" or is it some (img file) that i need to flash through TWRP

To Avoid Any Further Confusion , Could You Give me step by step instructions for what to do , please?
Please also give me details to which TWRP to use and all the configurations ( like ext4 or f2fs on system or data , whether to use format button, or advanced wipe) all that! Thanks in advance
Issue solved !!
How I solved ?
1. Using TWRP 3.2.2-0 I first Formatted data.
2.Then used advanced wipe to clean everything.
3.Then using change file system option in WIPE category changed my "data" partition from whatever to f2fs.
4.Then changed back to ext4.
5.Then changed back to f2fs.
6.Using PC transferred OOS zip file (5.0.8) to internal storage.
7.Flashed The file
8.Bingo !!! Phone booted up without a problem
Thanks @BillGoss , your provided links helped alot, though i used nothing from it but they helped me to recognize what the problem was, it was i think an encyption as well as changed file system format issue due to my previous flashing of pie roms.:good:

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
