Hello So I managed to update my LOS 14 to 15. Flashed latest TWRP 3.2.1.0 with Nexus Root Toolkit and installed Lineage OS 15 and Gapps for 8.1 without problem.
But today came out OTA update and when I hit install it opens TWRP that asks for decryption password.
I have never set any screen/SIM lock or password. As I checked there is no updated TWRP for Nexus 6 just this 3.2.1.0 that is not supporting Oreo based ROMs encryption.
Is there any workaround, without wiping data? Maybe with OTG stick and installing update manually... or just wait for TWRP to update/or contact them?
Thank you guys.
LOS forces encryption for years and recently not. Only way to decrypt is hit cancel when prompted for password, access and back up data to laptop or OTG flash drive (offsite), backup ROM to TWRP, move TWRP folders offsite, format data which wipes all data, move/restore all data and files back to phone, restore ROM, flash Fed-patcher V8 (must download before hand and move offsite with other data so u can now use it) to rid of encryption on LOS, reboot

Hi,
maybe someone here can help me or point me in the right direction for a guide. That would be much appreciated!
I have a Oneplus 3T (A3003) that I flashed to LineageOS 14.1 with Magisk-Root a while ago.
I have been stuck on 14.1-20171005-NIGHTLY-oneplus3 for a while now, because since then, whenever I tried to do a nandroid backup from within TWRP, the backup failed because of some kind of error on the data partition (I believe). I haven't flashed a new version since then and haven't come around to it until now, because everything ran very smoothly. :silly:
Since I would like to switch to a more modern ROM (I was thinking of going back to Oxygen OS (5.08)) I started playing around with it yesterday and noticed that TWRP (I think 3.2.0) would not start anymore. It will always get stuck on the logo screen.
I then tried to flash a new version (3.2.3.1) through the Official TWRP app. It still got stuck on the logo screen and I tried flashing 3.2.3.0 after reading about problems with 3.2.3.1 but the results were the same.
Can you please tell me how to get TWRP working again and how to flash OxygenOS 5.08 on my 3T or point me to the neccessary guides?
Thank you.

As OOS implies enforced encryption of data partition, going to an from it can be a bit tricky. Simplest way is by wiping using Qualcomm factory restore tool and then just OTA upgrade or flash latest OOS zip.

@r_wraith, I'm thinking that your data may be formatted f2fs and be encrypted but no on-boot password, and have a lot of data in your user data. This could cause a long start time in TWRP.
So try waiingt for about 5 minutes when you boot into TWRP. It may end up getting past the logo screen.

That worked, thank you. Yes, my data partition is/was encrypted.
Since TWRP seems to be working again, do I need to flash some kindof firmware upgrade before I flash Oxygen OS or is this included in the OxygenOS-Image and only needed for flashing ANdroid 8 Custom ROMS?

The OOS zip includes the firmware. Custom ROMs don't because they use the OOS firmware. The firmware is stored in separate partitions so it isn't affected by wiping the system and data positions.
Since you're coming from Los 14.1 you'll need to do the following in TWRP:
- take a backup of your current system
- do a factory reset to clear the data partition without losing the files stored on internal storage
- flash the OOS zip file
- flash Magisk 18.0 which will root the phone as well as prevent TWRP from being replaced by the stock OOS recovery

Dear xda members,
I recently installed the Oxygen stable 9.0.2 on OnePlus3T
The phone was unlocked, rooted and with twrp 3.3.0-1 installed
During first boot after installation, I received this error:
Decryption unsuccessfull
The password you entered is correct, but unfortunately your data is corrupt
The only way to continue is a factory reset (but I would like another way, if possible).
I was able to revert to Oxygen stable 5.0.8, but the error persist.
Is there any procedure to access the encrypted data partition and recover files stored in it, before wiping all?
Thank you.
Kind regards
you need to do a factory reset from the recovery menu.You will lose all your data but its the only way.
You should totally flash the 5.0.8 fw after flashing the offical pie OOS. It has been discussed in the official thread here at XDA.

Thank you very much for the information!
This is what I did
1 Boot recovery and press cancel when it asks for password
2 Adb push needed files in /mnt
3 Flash the rom (OnePlus3TOxygen_9.0.2_28_OTA_082_all_1905110010_f09a2bfe8e361d.zip)
4 Flash the firmware package (oxygenos-9.0.2-bl-km-5.0.8-firmware-3T.zip)
5 Flash twrp 3.3.0-1 again in the recovery partition
6 Flash Magisk 19.2
7 Wipe cache / dalvik-art (with errors related to mount storage)
But I found the same error of the first post. Which is my mistake in the procedure?

You could have flashed the firmware first, ROM second, but I don't think it would have changed anything.
We used to have this problem with the closed beta and with the open betas as well.
Once you wipe your storage, flash Pie, boot it, it doesn't happen again. I've been to Nougat, then back to Pie, no issues.
Have a xiaomi mi8 with lineage os on it (official build) and twpr. Did have encryption working before but had to wipe the phone and lost all is and encryption and can't remeber for the life of me what twrp version I used to get encryption working and what steps I took to get there. I try encrypt the phone now and it gets stuck on lineage boot logo. Switch it off after hours of being on the lineage logo and get to twrp and it does not ask for a password but says it can't Mount my partition when j try browse file or factory reset (has to be format option to start again)
Any ideas what twrp version I need and what steps in what order I need to take to get encryption back
Hey guy!
after updating (dirty flash) from Evolution X version 2/14 to 2/19 all my data on sdcard-folder is encrypted and i cant write any data to it.
the whole procedure was to first uninstall magisk, dirty flash new Evolution X version, flash magisk again.
Since then I can only boot into recovery (twrp)
Does anyone has an idea how to get my data back and not full wipe my phone?
Backup data in twrp is not possible since it cant create a folder ;(
Thanks a lot!

AFAIK your only option now is to format data in TWRP.
I assume the phone was encrypted before and TWRP would normally ask for the PIN, but now fails to recognise that the phone is encrypted. I don't know why TWRP doesn't ask for the PIN in these situations.
I have previously considered asking mauronifrio if it's possible to have a force decrypt option, which allows the user to enter the PIN if TWRP doesn't automatically ask for it. I just never got round to it.
Hi,
I am running the official Lineage 16.0 build from Microg with the latest Orangefox Recovery.
This week I installed an Lineage Update, the phone booted into Recovery, I entered my pattern, phone said unable to decrypt but did flash my update and rebooted. But now I lost magisk and have no root anymore. So tried to boot into recovery, enter my pattern, but decryption fails....
So I put the magisk .zip on a microsd card, but cant find it in my recovery to flash...
Formatting data will wipe all my apps, images, settings and so on am I right?
Is there a way to fix this?
How do you guys update your Roms with magisk root? That's the first time I used magisk, used the addon from lineage before to root my phones.
