I encrypted my phone with ACIP 10 Rom with a 4 digit pin. Now I wanted to change back to a sense based rom, ARHD 93 to be precise, and performed a fullwipe including internal storage after flashing rom and kernel. After rebooting the rom asks for a password to decrypt the phone and even though the pw works perfectly fine to decrypt the phone in TWRP, it won't work on the sense dialogue. I entered settings and enabled usb debugging but the device won't show up on my pc (still decrypted). Unfortunatly fastboot is broke on my phone.
Has anyone had similar problems with decrypting or knows if it is possible to decrypt the device from TWRP?

Do a factory reset using the stock recovery (not twrp), then wipe and clean install your rom again and you should be fine. But first, fix your fastboo problem since you'll need it to flash the stock recovery.

Thanks for your help! I'm still stuck on the fastboot issue. Tried it on several different pcs with win 7,8 & 10. ADB command boot to fastboot mode works, after the phone enters the mode the connection is lost. Could this be the result of a faulty microusb port on the phone? Or is the problem soley on the software side?
Solved:Didn't fix the fastboot problem, but this wasn't necessary. Instead of a factory rest go twrp Wipe - >Format Data. This completely removed the encryption and thus I can use the phone again

Hello,
Thought I would share my recent bad experience and the resulting solution.
My phone was on a GPE ROM, and I encrypted it for work reasons, encryption went smoothly, but once encrypted, it was impossible to go into recovery with the encrypted partitions visible (hence impossible to flash a new rom or even do a factory reset which is the only - or so I thought - way to remove encryption).
After many attempts including flashing the latest TWRP (not solved yet, they say 2.7 should include a solution) I was still getting the "unable to decrypt phone" error after entering the password (which works perfectly on regular boot) in TWRP.
Eventually, through a lucky mistake, I found the solution, at one point I mistakenly re-locked my phone (fastboot oem lock), later when I was trying to flash a stock recovery I realized I had to unlock it again... well, unlocking it through HTCdev automatically does a factory reset, regardless of the encryption!
viola, problem solved!
Hi guys,
I am kind of stuck here.
I am using the xtrasmooth rom with the elemental x kernel (Marshmallow) and everything worked fine. Today I decided to add a little more security, so in the security settings I required a password when starting up android. I had been using the feature a while ago on android 5.x and everything worked fine.
Somehow my phone crashed today and now I am stuck on bootloop. It is not even asking me to enter a password.
However, I can access the recovery (TWRP) normally after entering my password to decrypt storage. I tried to wipe system and restore a backup. Still no success. I did a fresh clean install but no sucess again. It's always stuck on bootloop.
I don't want to factory reset or flash the complete stock image, since I do not want to lose my data. I tried to active ADB Sideload in TWRP, but somehow that is stuck at "starting adb" after cancels after a while with no success.
Do you guys maybe have an idea how to fix the problem? I guess I would need to disable the password but I do not know how to do that without an functioning rom.
Many thanks for your help!!
Reboot to your bootloader and use fastboot to flash
Sent from my Nexus 6 using Tapatalk
stupid me. That would have worked too.
I just connected my phone to the computer using twrp, used the file browser to push a file to the phone (regular storage) and installed another Light rom that is close to stock.
Everything worked fine. Must be a ROM or Kernel Issue. I will report to the according thread in this forum.
Thanks!!
Hi all,
What happens if you take a stock 3T, upgrade it all the way to Nougat the normal way, then proceed to unlock the bootloader, flash TWRP and supersu?
Does the TWRP 3.0.3.0 build have an issue with decrypting and mouting the sdcard? Is that even a problem in the sense of waiting until a fixed version of TWRP is released? The point is to just flash supersu for the moment. No other need to access that partition from recovery, is there? Or does it directly impact my ability to upgrade TWRP in the future?
And another question: would decrypting the phone after the stock to Nougat update, and only then flashing TWRP&root be of any use? Is this even possible at the moment? I can hold on without encryption until there's a proper version of TWRP, kernel sources are released etc.
I don't seem to find any info on these scenarios. Has anyone tried any of this?
Thank you!
Good questions.

I can confirm 3.0.3.0 has problems with decrypting and mounting sdcard. A new version of TWRP should fix this.

Well, the need to access partition from recovery depends. You won't be able to flash anything from TWRP. I could sideload different recoveries without decrypting but had to decrypt (with the format userdata command from cmd prompt) to revert to 3.5.4 from TWRP. In the end I mostly downgraded due to bluetooth issues.
I am having the same decryption issue... TWRP shows 0MB as the storage
What should be done now..?
you can get past encryption by formating data in twrp, though that deletes all your data, back ups and everything, but with that you have the phone completely rooted and then you can download or transfer data via mtp to storage, flash super su and verity.

Did that already but did not work.. Even tried the setting up of pattern method.. that too did not work...
Also force decrypted with Toolkit but still the same
just to make sure. flash twrp via fastboot( I flashed the 3.0.2.0 version) then when booting to twrp you get get the screen where it asks you for a password, skip that , just swipe to continue then go to wipe, then format data, type "yes" to confirm, the at the next booting it shouldn't ask you for the password anymore. That did it for me. Maybe you should try adb sideload to flash verity.img and supersu

why not use 3.0.3.0?

Don't really know, probably tried solving the problem by trying with the older version and then didn't feel like upgrading to the newer 3.0 after fixing the problem.
Hi guys.
So after developing an audio bug on Lineage OS 15.1 (a story for another day) I decided to restore one of my old backups via TWRP (unofficial decrypt-friendly version).
I press restore, get some sort of error about mounting /system and then on reboot I get a message asking me to factory reset which takes me to TWRP. Not too surprised by this point because the Huawei bootloader is quirky.
However, when I go into TWRP, it simply gets stuck on the loading screen endlessly. I left it for several hours and it didn't budge. Rebooted several times.
I tried reflashing TWRP via fastboot, no dice, same result. I flashed the official recovery too. That loads fine, but obviously I can't restore with that because it doesn't support encryption.
So I'm a bit stuck here. I've read somewhere that it takes ages to load when you have plenty in the data and cache folders, which I do, but I really don't want to wipe because I have a full week of precious holiday photos and videos I wasn't able to back up (No access to a PC at the time).
Any advice?
Not sure how to fix the TWRP restore problem, but have you tried connecting to your PC while in TWRP? If I remember correctly, it'll allow you to connect to a computer so you could access your storage and backup the files you need.

Problem is that everything is encrypted, so even if it does show up it will be gobbledygook (nonsense).
Lesson to learn from this: always backup before trying to update ROM or flash something new.
I guess what you can do is to try to flash Lineage again and see if you can make that boot.

Yeah, there's a few reasons that happened. Usually I autobackup everything but I had been away from wifi for a week. I backed stuff up via Titanium but obviously that got encrypted too. Restores also have never given me problems in the past so I didn't expect anything to go wrong (still not sure what did).
Anyway, I'm not sure how to flash lineage without TWRP, especially with everything encrypted. To have any chance of getting it to work I'm guessing I'd need to flash it the same way I did originally, which was with everything decrypted which makes the issue moot. Maybe I'm wrong though.
Try flashing a treble rom via fastboot. Then wipe data and cache.
fastboot flash system "GSI. img"
fastboot erase userdata
fastboot erase cache
fastboot reboot

Thanks, but I'm trying to prevent loss of data. I'd probably just use e-recovery if I don't mind losing data and want to reset to start again from scratch.
Erasing userdata and cache is just factory reset. It won't wipe your internal storage which where your photos are kept.
Ok, turns out once I chose the "download latest firmware and stock recovery" from erecovery it didn't wipe the internal sd data!
Everything is still there and I can access it now from the huawei stock ROM even though I came from lineage OS. It thankfully does not reset the encryption keys or the pattern lock, so you'll be just fine once you do a system boot and go through the regular setup process.
I recommend this approach because it's pretty hassle free.

Glad you found a way to keep your files, mate
So this happened, first time unlocking my phone, installed TWRP and everything good, now I wiped all of the phone and I can't flash any ROMs since TWRP can't decrypt the phone either I can't find a way to revert recovery and system to the original state.
Tried Flashing various versions of TWRP, none seem to work.
Tried the vbmeta-patcher
Formated the whole device.
Tried both MiToolUnlock and Tool All in One
Also, after flashing any version of TWRP and booting, it always goes back to the previous version (unofficial 3.3.1-25 by Mauronofrio)
I don't know what else to do. Any help?

Try flashing the correct fastboot ROM for your phone, using the Mi Flash Tool.
Then don't wipe everything in future. Stick with wiping just cache, dalvik and data. It's very rare you will need to wipe anything else.
Try this tool to erase and decrypt your internal storage

Than install rom using usb otg.
