hello there,
Z3 D6633 here running 5.0.2 (HK) with TWRP rooted with superSU. Trying to upgrade to the newly released 5.1.1.
The phone had been be Encrypted some months ago and everything is fine. However, when I booted into TWRP to try to patch in 5.1.1, TWRP popped up with a password prompt. I entered the decrypt password (and other passwords I can think of) but TWRP replied with:
Unable to mount storage, and
Failed to decrypt data.
Google tells me there had been some issues with TWRP 2.8.4.1 to 2.8.6.0 unable to decrypt encrypted volumes so I went and grabbed the latest XZdualrecovery 2.8.21 and ran that in. All seemed fine and TWRP was updated to 2.8.7.0. Unfortunately, upon booting into recovery, TWRP still count not decrypt the volumes no matter what passwords I enter.
Does anyone have any ideas to get around this, short of a factory reset..? The SD card is also encrypted so I am trying to avoid factory reset if possible..
Thanks in advance
No. I find it ridiculous that it is simple and easy to encrypt, but to decrypt one needs a full reset losing all data? Android is fing lame. Can't wait to buy a tablet so I CAN encrypt both phone and tablet. At least with a win7 tablet decrypting will never be an issue. Android is more of a toy that destroys eyesight imo.

I have a Chinese version of oneplus one with cm11 M9 installed. Everything worked fine. A week ago, I had the phone encrypted. Again things worked fine, except today when I tried to use twrp recovery to do a full backup. Twrp booted into recovery. But twrp did not ask for password to decrypt the phone's storage. Naturally, twrp complained that it could not mount /data, etc.
I searched online. It seemed that twrp is supposed to ask for password when booting into recovery.
Twrp could not do the backup since my internal storage was not accessible to it.
I thought that maybe if I update twrp recovery to 2.7.1.1 the problem might be solved. Nope.
Please help.
If I cannot do backups, I may have to give up encryption.
Thanks in advance.
No longer a problem. I now use online nandroid backup app, which worked flawlessly.
Hey guys,
got a big problem. Got an encrypted and rooted One running Android 6.0.1 (Sultan CM13).
When I want to reboot into recovery I have to enter my pattern to decrypt the phone, but although I enter the right pattern, TWRP says it cant decrypt and mount my phone.
So my problem now is, I can't just do a factory reset, cause TWRP is bugged and via fastboot it always says "no permissions".
Help very appreciated!

Try running fastboot with root privileges if your on linux, which it sounds like.
Hi folks,
My MI4C is on the weekly MIUI 7.4.x, I am now looking to upgrade, hence as usual I rebooted in recovery.
The phone has obviously root and unlocked bootloader.
TWRP is asking for my encryption password, which I know, but no matter what, TWRP does not flipping accept the password!
What can I do?
Do you know if you have the Nougat bootloader or the old one?
I have not found a TWRP that can successfully decrypt it Nougat bootloader ROMs. If you are not on the Nougat Bootloader then I recommend trying Team Superluminal's TWRP, since that is the only one that worked with encryption enabled for me I think.
Have you got a working rom/os on the phone ?, If you do have try to add a password on the rom, hope the twrp has a new working crypto after that and ask you for a new password. If it didnt work try to reinstall the twrp by erasing it first.
Hi, I am on the Nougat bootloader, I tried to change the encryption password, tried to remove the encryption, but nothing worked, TWRP is still asking me the password to access the data partition.
What can I do?
I cannot wipe the phone, as I use it for my work,how can I upgrade TWRP when encryption is on?
Hi folks, anybody in my situation? I would like to avoid wiping the entire phone just because of the TWRP password bug.
I changed to a PIN password, but nothing works.
Hello, been running twrp with encryption on Lineage OS 16 without problems for 6 months. But yesterday I flashed new android Q factory image and was unable to decrypt my data in twrp, even when I put the right password in it says ''password failed, please try again''. I tried flashing various factory images, custom roms even Lineage 16 but problem persists. I had this same problem back then when I first bought this phone but managed to solve it, I can't remember how I did it. TWRP is up to date. Any ideas? thanks.
It's TWRP issue. Sadly TWRP 3.3.1 is not available in zip format. Only in .img format. In 3.3.1 this problem is resolved.
As workaround you can remove any PIN, fingerprint and set security to none in setting and you won't have to enter anything in TWRP. Do whatever you want in TWRP and then set up PIN and fingerprint again.

Yeah I know this, but why did it started to do this after flashing Q factory image? TWRP worked without any problem on various custom roms. Actually now I remembered that while flashing Q factory image there was a problem mounting vendor and system partition, so I went back and flashed Lineage 16 and there this TWRP password thing started if I remember correctly.
I came here looking for the answer to this very issue.
I shot off an email to TWRP if they were going to update the latest zip to 3.3.1 because fastbooting to the img works fine.
I might try the trick of removing pin and security and try again.
I have the same problem but with 9.0, if I have a pin it's ok it decrypts just fine but when I have the fingerprint set up I get this problem, it kinda blows, I'm not using twrp everyday but it still blows that you have to disable security Everytime you want to use it, also, last night I used twrp with the security on it could not decrypt so and when i tried to reboot into system, I got the prompt to install the twrp app, I screwed up and used the slider instead of the button to cancel the installation and it messed up the system, so watch out for that crap.
Tried flashing the latest Magisk update in fastboot (v20) with the latest Android 10 update, and my phone went into bootloop, so I reflashed the factory boot.img and got stuck loading on the G splash screen for 16 hours until I shut it off. I booted TWRP to backup the /data partition before reflashing to factory and starting fresh, but it won't mount (shows 0mb) and doesn't prompt for any decryption passwords. Won't boot OS even with dirty flash and OTAs. I need to backup the data partition because I have a lot of important user data on it. Any advice on getting TWRP to decrypt the data (had fingerprint set up with PIN as unlock)?
Seeing as how it's 4 days after your post, I'm going to guess you've already learned that you're pretty much FUBARed. I had the same thing happen last month. Unfortunately, the only way out is through, and in this case that means going through the process of a full wipe and the subsequent hours/days of installing all your user apps and setting everything up from scratch.
This is because of a incompatibility in recent builds of TWRP with Pixel2 images past April that makes it impossible to decrypt the data partition. The only workaround is to wipe the entire device, install the Pixel2 factory image from April, flash TWRP, boot the device and setup your password/pin, boot into TWRP and decrypt the device one time, and then flash the latest Pixel2 factory image and TWRP/Magisk like normal. Outside of that, the only other option is to remove your password/pin every time you need to access recovery.
As for the exact details of how or why this is an issue, I can't say, as I don't have the technical know how to parse a lot of what I've read about the problem, only just enough to understand what the problem is and how to get around it.
