[HELP] Data encrypted unable to decrypt with TWRP - OnePlus 6T Questions & Answers

My device bootlooped after new update, it seemed fine, i update it normally last week and it worked fine. today i did a TWRP backup of all of the partitions and then rebooted and it went into bootloop. I was able to flash all the partitions again with the flash-all-partitions.bat and got it out of fastboot. Now i can boot TWRP with an .img again.
The problem is that my data is all encrypted, like it mounts but its all in ramdom folders with ramdom names, and TWRP is not asking for the code to decrypt it. I dont know how to decrypt the data. How can i decrypt it? ( i know the code as it was my password).
Thank you

I would say format data and re-flash rom via twrp, that should remove encryption (but you loose all of your data) and you should be able to normally boot.

Rooting not successful, even though it says it is

I have a US996 with an unlocked bootloader. I installed TWRP (although I still can't get it to decrypt data). I installed the latest SuperSU - and there were no errors (although without the ability to decrypt, TWRP couldn't wipe Dalvik/cache).
But after rebooting, Root Checker still says I'm not rooted.
What am I doing wrong?
Figured it out. Unless I disable the default encryption to formatting Data, installing SuperSU fails. Once I format Data, the install works properly.

How did you disable default encryption? I flashed twrp but in recovery it always says it had to decrypt in order to mount. I don't know the password twrp is asking for. Thanks
I followed the instructions and flashed TWRP. However it asks for a decrypt password when TWRP loads. How do I get past this? I formatted data twice and I am unable to flash SuperUser since I can't see any mount points. Its read only. Thank you to anyone that can help.
SOLVED:
Here is what I did wrong. After I ran all the dirtycow commands and got permissive root access I rebooted into TWRP. TWRP showed that the sdcard was encrypted. What I kept doing at this step was formatting the sd card which is correct, however I kept rebooting back into system. That was my mistake. I needed to immediately reboot back INTO TWRP RECOVERY instead. Once I rebooted directly back into TWRP recovery after the format I was able to view file system information move su.zip to sd card and install SuperUser.zip from TWRP.
When rooting my H990ds the guide said when TWRP asks for a password just press cancel. It should be the same for you too.

Sorry, the text you quoted from me should have read that disabled default encryption *by* formatting Data. Formatting Data is what takes care of it.

help needed to recover encrypted data off the phone

Here is a quick review of what happened:
The phone was running well on Lineageos 14.1, encrypted with a pattern, with TWRP 3.1.1 as recovery. I’ve then been notified of an LOS update to 15.1 Oreo and got excited. Booted in recovery, entered my pattern to decrypt, took a full TWRP backup, flashed Oreo modem and firmware and dirty flashed (I know, bad idea) the LOS 15.1 zip.
It got stuck at boot logo. Even if I didn't have high expectations for it to work I just thought I would try the lazy way to see and use my fresh backup to restore in case of failure like I always did successfully since my Nexus One.
This time was different because as I rebooted in TWRP to restore, it didn't ask for my pattern. You guessed it, the data partition is encrypted, no access to my backup or anything on the external storage. I can mount data and see the weird encrypted file names but that's it. I tried different version of TWRP, but it never ask the pattern. Even the terminal command 'twrp decrypt *******' doesn’t work.
I then tried to wipe data and flash LOS 14.1 again but it gets stuck saying that android has no access to data partition because it’s encrypted and that I need to format. I pulled out my sim card and started to use my old oneplus one while waiting for the new version of TWRP 3.2.1.1 with the feb security patch support thinking it might then be able to decrypt but no luck still.
I can go without the phone for a while, I’ll buy another one if I have to because there is some precious data on that phone and I can’t make my mind that the data is there, I know the encryption key but I have no access to it. There must be a way, I just don’t have enough knowledge about how this encryption thing is working.
Any help would be appreciated, Thank you

Try flash codeworkx TWRP ...
it should decrypt your data partition ...

I had tried it when it came out and I just tried it again. No difference!! It looks like twrp doesn't even see that my phone is encrypted. I've read a lot and tried many different things and I'm out of idea. All of the people I've seen with this problem have given up so they could get their phone back and running by formatting the partition, losing their data. This option is not one for me. I'd rather buy a new phone hoping for an eventual possible solution. I know the data is there, and I know the pattern key...... I mean, there's got to be a way......

Failure to decrypt in TWRP?

For some reason I cannot decrypt when booting TWRP. On a normal boot, I get the prompt to enter my PIN, I enter my PIN, and it boots. In TWRP it says "failure to decrypt."
I'm using 3.2.1-7 of TWRP, which worked before, but now it's unable to decrypt my internal data.
Halp?
Edit: I guess when I get home I'll install an older version of TWRP and see if that helps, but I am otherwise sunk.

First thoughts : Backup internal and format data.
Perhaps try https://androidfilehost.com/?fid=818222786056030640 but that's only for lockscreen but you'll never know
edit : or try like another twrp3.2.1.0 (but will result in repair data too) or 3.2.1.6

I mean, I know I'll be able to backup all my data since I can access it on a normal boot. Just very weird/annoying. I'm going to try flashing an older version of TWRP and seeing if it works.
...Maybe I should backup my data first
Did you ever find a solution to decrypting in TWRP? Currently having same issue with LOS15.1 and TWRP3.2.3.0.
I wasnt able to get mine to work, so I just backed up all my data and reformated, if you lost root you can still sideload magisk, dunno why but you can

Unable to decrypt data

Hello,
So I tried to install LineageOS 17 (Android 10). And there were errors. So I decided to return to RR. And what i see is that the data is encrypted and I have to format my phone. When I click on this button phone restarts to recovery(orange fox) where I have to enter PIN. And everything is fine but in logs I see this:
Failed to encrypt data.
Unable to decrypt with default password. You may need to perform a Format Data.
Unable to mount storage
I can't use my device now. After booting to system same button and text appears. Please help
Update.
When I was writing this thread I couldn't find option Format Data but when I was searching in the recovery I finnaly found it. Now everything works fine
I don't think you can flash anything without first formatting the storage . This happened for me on Redmi6pro (sakura). That was the only option left for me that time.
hope you had a back up otherwise you will lost your files.
if you had a pin to unlock your phone put that ping in the box asking for decrypt the phone. if that doesn't work you may need to format data and reinstall.
If that's the case, restart into recovery (power+vol_up)
-go to manage partitions, format data partition.
-restart to recovery
-full wipe (data, dalvik, cache system)
-flash rom (can be the same) after a format and full wipe should work well i had lineage and was great.
-restart to recovery
- flash gapps and magisk if you like.
-restart into system.
Hope you get luck.,

If you this exact text, then you can pretty much say goodbye to the data from internal storage. At this point, there no way to rescue the files... Sadly, had the exact thing happen to me & I lost all my stuff

Decrypting "Internal Storage" aka "/data/media/0" aka "/sdcard"

Hi
I was trying to flash xiaomi.eu (xiaomi.eu_multi_HMK20MI9T_V12.5.2.0.RFJCNXM_v12-11) custom rom to my Mi 9T device via TWRP recovery
I booted into recovery then I noticed TWRP isn't asking for a password for decryption
So dumb me ignored it and "Advance Wiped" all partitions except "Internal Memory" and flashed the rom from "USB OTG"
then problems started to appear
first the rom didn't boot and was stuck in a boot loop
so I wiped and reflashed the original "miui_DAVINCIGlobal_V12.1.4.0.RFJMIXM_e0ac13ed89_11.0" rom via TWRP from "USB OTG" to be able to back up my files and do a proper format/decrypt
but the internal storage is now still encrypted and cannot be accessed
I tried twrp decrypt command with all combinations of passwords pins pattern numbers that I used since first bought the phone but none of them worked
I know I should have backed up my files
Now I want to know how can decrypt /data/media/0 aka /sdcard aka Internal Memory and get my files
like mounting it in windows through some adb and other software and decrypting with known key combinations and passwords
or through twrp or whatever that maybe work
I really can't afford to lose my data AGAIN
yes, that wasn't my first time!!!!!
I promise if this gets right I devote the rest my life to the open-source community
excuse me for my bad English.
When flashing a custom ROM, or going back from, you HAVE to Format (not just Wipe) Data
(And you don't need to wipe System because new ROM will overwrite it anyway, and you better never wipe Persist and so)
Obviously, you must backup your photos, data, etc, before switching the ROM
Data on Internal memory is encrypted, and not by your unlock pin (unlock pin just serves to verify and read the key).
New ROM reinitializes the encryption key
Hence, AFAIK, you cannot decrypt anymore because you don't know the encryption key that was used for data on your Internal memory
Seems you have similar problem as I have

ok
a question
why the twrp was not asking for decryption in first place?

No idea - ask devs of your custom ROM how they implement encryption and what is the proper way to install the ROM
