OP3T Stuck in TWRP after flashing LineageOS

Hello out there,
my problem is a bit annoying. Everything is fine if I use my OP3T with Oxygen (4.0.3) and TWRP (3.0.3-1). But I want to use LineageOS with TWRP and cant, because my TWRP isnt working after flashing lineage.
"Normal"-Setup:
- TWRP 3.0.3-1
- Oxygen 4.0.2 or 4.0.3 (doesn't matter)
- supersu 2.79
- Encrypted Device
"Lineage"-Setup:
- TWRP 3.0.3-1
- lineageOS (lineage-14.1-20170214-nightly-oneplus3-signed.zip OR lineage-14.1-20170208-nightly-oneplus3-signed.zip - tried both, doesnt matter)
- supersu 2.79
- openGApps for 7.1 nano
- Encrypted Device
My Problem is, that I can boot up lineage and use it, but if I reboot into my TWRP to flash something or make some Backups, it asks for my encryption-passphrase, it says it is okay and boots into the twrp main-windows. After that I can't touch anything (stuck in mainmenu) and after a few seconds it results into a black screen (plus white LED) and I am forced to reboot the device. After that reboot I have to reconfigure lineage (seems to loose data).
Does anyone have an idea how to fix this annoying "bug"?
Thank you very much!

EDIT: I found that Thread after searching for a issue like that in the lineageOS official Thread - I will try this and report! - Thank you! https://forum.xda-developers.com/on.../recovery-official-twrp-oneplus-3-3t-t3543391

I had the exact same problem when I hab LineageOS installed! It would always lose all its data. After flashing and reflashing a hundred times, I ended up reverting my OP3T back to stock using a OnePlus forum guide (I'm a new user, so I can't post the link). I am now back to OOS 4.0.3 but can't even get SuperSU to work. Whenever I flash it (with or without the dm-verity fix) the phone is stuck booting forever.
I found the post you linked to aswell but haven't tried flashing LineageOS using the new TWRP. But I can tell that the new version doesn't help rooting OOS...
Did you have any luck flashing LineageOS by now?
Edit: With the newest Lineage Version I always get an error when trying to flash it. Do you have the same problem? The nightly from two weeks ago seems to work better.

Use latest TWRP 3.0.4.1

That's what I'm doing... Could the dm-verity be a problem? There are two versions, one with opt and one with force in the name.

Thank you for your replies! The link (TWRP 3.0.4-1) worked like a charme!
@Tafelbomber: I would recommend you to start from scratch. But please be warned: you will loose your data! Make a backup first!
1. Delete everything with fastboot -w
2. Flash the recovery noted in my first post with fastboot flash recovery <twrp-filename.img>
3. Optional: Restart into the TWRP and flash the OOS 4.0.3 to make sure that you have a clean OS installed befor flashing lineage
4. Flash lineage OS + additional ZIPs (like supersu, betterbatterystats, Gapps etc)
5. Clean Dalvik and Cache!
6. Reboot and have fun. --> Sometimes you get problems with the encryption chain (Red Error --> in my case the fastboot -w did it for me)
Good luck - I will close this thread - thanks again for your help!

TWRP 3.1.0 - wipes userdata and more

I install latest TWRP 3.1.0 version today.
All the user data, some apps (Waze, Gmail, Gmaps...), SMS were wiped.
I have RR-N-v5.8.2-20170218-oneplus3t-Official currently installed.
I reinstall some apps back.
After system reboot all seemed fine.... But after boot to recovery (TWRP 3.1) and than boot into system all was gone again.
It looks like every boot to recovery wipes user data and some apps...

Flash 3.0.4-1 again

Same problem here with 3.1.0.0.

I flashed 3.1.0.0 img with 3.0.4-1 and do not have the issues OP is describing.
Edit: stock Open Beta 3 rooted.

I did... and restore system from backup BUT some userdata is gone forever...

Apparently, the official TWRP 3.1.0-0 for OnePlus 3T only works with Oxygen OS. So far, only users using custom ROMs have reported issues with partition wipes after flashing the latest TWRP.

Happened to me on OOS. Went back to 3.0.4-1
Sent from my OnePlus 3T using XDA Labs

It was updated to 3.1.0-1 try that

I suppose this of because of the official TWRP 3.1.0-0 is not using the backported F2FS driver. I'm using EXT4 filesystem on data partition so therefore I'm not experiencing any data loss.

Was on RR 09.03 with OB3 firmware, it completely destroyed my phone. Bootloops, impossible to go back to recovery, when in recovery, impossible to see files to flash them, even going back to 3.0.4.1 did not solve everything, reinstalled Freedom OS but had screen total freezes.... Had to go through the total disaster recovery utility, and I am still re-installing everything...
TWRP 3.1.0.0 ate 4 hours of my flash-addicted life... FML !!!
**STAY AWAY FOR NOW**

Blu_spark 3.1.0 version is not affected by this, only the official.

Stock OOS 4.0.3 and TWRP 3.1.0-1 = ALL GOOD!

Can confirm. TWRP 3.1.0-1 works fine. (rooted OOS 4.0.2)

I had at least two serious issues with official TWRP 3.1.0-1 and LineageOS:
1.) After a first flash attempt via fastboot I was no longer able to unlock my phone with my PIN under LineageOS.
2.) When booting into TWRP I got a black screen - unable to do any useful.
3.) After I could no longer unlock my phone under LineageOS I reinstalled LineageOS from TWRP 3.1.0-1. All looked fine until I rebooted from TWRP into LineageOS: TWRP obviously wiped my device and I was offered
the setup wizzard of LineageOS. All my setting were gone.
I had issue 3.) already with TWRP 3.0.3-1. I immediately reflashed TWRP 3.0.4-1 - the currently only working TWRP version.
I would like to add that I had removed any encryption on the phone before I started at 1.). My device is still unencrypted. I once removed stock encryption because I heard about problems with TWRP and encryption.

Which version of TWRP?

After last update of OS lost root.
Had to install TWRP again, after install got into bootloop, flushed OP recovery again but had no access to recovery at all.
Finally flashed latest version of Oxygen-OS, 4.1.6 running on Android 7.1.1
I understand sometimes newer versions of TWRP might not work well with latest OS
All this said.... what would be the safest yet most up to date TWRP version for the OP3T?

3.1.1.0 i believe or you can flash Blu-Spark TWRP

I'm using Blu Spark's TWRP latest and it works wonderfully with OOS / FreedomOS v4.1.6 It's TWRP v3.1.1-x Blu_Spark v37 for OP3 & OP3T

TWRP v3.1.1-x Blu_Spark working with both custom and stock rom

TWRP 3.2.0.0

Has any of you guys tried the newest TWRP 3.2.0.0 for OnePlus 3T? Did you find a bug?
Thanks.

I wonder if it triggers dmverity and how to avoid it if we just want to upgrade twrp...

I assume you flash the updated Recovery followed by the patched firmware, which i assume you already have? I don't even know if the firmware is necessary but whenever i flash anything i also re-flash the patched firmware while I'm at it. No reason not to.

Alright, DM-Verity will be cleared if you flash the newest Magisk beta, and TWRP 3.2.X.X is working fine. I don't think Teamwin would release an official version of TWRP without making sure it's completely free of bugs. It flashes Oreo ROMs (Cardinal Xtended, N2Os) and also flashed OOS 5.0 very well. Add-ons such as Magisk and Magisk Modules flashed flawlessly.

Help getting from LineageOS 14.1 to OxagenOS 5.08 (Something wrong with flash mem?)

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
