[Q] Phone stuck in TWRP

Hi,
I just unlocked my M9 and installed TWRP. When I flashed my ROM it said no OS installed when I rebooted and the phone stayed on the HTC splash screen. So I tried flashing boot.img in adb which tells me in need s off to do that. Now I tried reflashing recovery but now it says i need s off for that too! Someone please help me.

update
I got it to reflash the recovery

I had this problem. You need to reflash TWRP BETA (Latest beta). Reflash in Download mode. It should be smooth running from now.

I can't reflash stock recovery

Hi, yestarday I flashed CM 14 with TWRP to try it, and today I have tried to return to stock rom & recovery but I can't do it. At the beginning I have tried to flash stock recovery that I have downloaded from op.net with fastboot and I couldn't do it and after I have tried to do the same process but this time flash it with TWRP and also this time I couldn't able to fix it. In fine I have installed the stock ROM via TWRP and I managed to install it but now the problem is that I still can not install the stock recovery and accordingly I can't install op3 update.
An another problem is that I have tried to re-lock OEM from fastboot and when I try to turn on the phone, is asks me a pin to enable it and I don't know that pin because I haven't set no one

No it isn't. Because I managed to put stock ROM into it via adb with push command and after I have installed it from twrp that works. My only problem is that i can't flash stock recovery.

i have the same issue. Tried many times but i'm getting a black screen after one plus logo for both stck recovery and unmodified twrp. only moidified twrp is working. please let me know if u find a way to resolve this.
thanks in advance

you can reboot in to stock recovery without any issues?? I think I should give it a try. And you are saying the bootloader is locked again ?

Great. Can I place the file in beta8 rom .zip file and flash it using adb ??

If this procedure doesn't you can download an older version of oxygen os and update it via ota. At the first attempt when you will try it will give you an error and at the second attempt It will download all the ROM again and it will reflash by itself

I suggest you to try at the beginning with the beta 7 because if that procedure not work for you, you can't downgrade to beta 7.

Thank you.
Will let you know if it worked.

I had that problem.
Solution as follows, worked everytime for me: (I have not tried this method with the newest beta 8)
1. Flash OOS 3.2.6 firmware in twrp.
2. Reboot to fastboot and flash official oxygen os recovery downloaded from the OnePlus website. (This is still the old version for some reason, thus why it won't work)
3. Side load community build with oxygen os recovery, this will flash the new firmware back and update the recovery to be community build compatible.
4. Before rebooting erase everything (factory restore)
5. Reboot to OOS, finish setting up.
6. Turn on advance reboot in developer settings.
7. Reboot to recovery via the reboot menu. First time boot into the recovery may take sometime, but it has always worked for me.
8. After everything looks good, go ahead and OEM lock in fastboot, recovery should work as usual this time and format your phone

OP did you find a solution to this?? Im on the same boat as you

Root for OxygenOS 4.1.6

Hello everyone, I am using OOS 4.1.6 on my new 3T, however I am unable to get root even though I have already tried with latest TWRP, magisk 12, and SuperSU 2.82. Nothing worked everytime I've got not rooted on root checker.

Please describe in steps what you did.

Hi,
We unclocked the bootloader, then we did flash with twrp 3.1.0 and installed SU 2.82.
After doing all this, the phone was not restarting.

Well first of all, format your whole phone over TWRP. (System too, but make sure you have the full Oxygen OS zip on a computer.)
After formating all partitions, move the full OOS zip and Magisk 12.0 on your phone. Flash the OOS zip, restart your recovery and flash Magisk after it.
That worked 100% for me all the time.
If you still need assistance with that, we can setup Teamviewer so I can guide you through this.

Same here! The phone freezes in boot animation screen. Even the animation stopped!

Guessing it's about the f2fs file system. I used to have a situation like this with Oneplus 2. My step was to format data and cache partitions back to ext4, and that worked.
Using 3t now, still not rooted. Don't want to start over after bootloader unlocking

I had the same problem and was solved with twrp 3.0.4-1 and SuperSU-v2.82.

Ok, I will try and update here then.

I'd say wipe everything possible in TWRP except for system partition, then boot the system and then eventually flash some kind of a root package - either Magisk or SuperSU. I always do it that way and it works. I am not really sure but otherwise it might have something to do with the data encryption.

Use following and you should be all set (just did it 2 days ago):
1st Flash Stock Recovery (go back to stock - https://forums.oneplus.net/threads/...-3-3t-and-go-back-completely-to-stock.456232/
Flash TWRP after you achieve STOCK OS 4.1.6.
Use this TWRP version for now (there is some issue with 3.1.1-2 i saw on forums):
twrp-3.1.1-0-oneplus3t.img
To Root just use Magisk-v13.3.zip (IMO way better than SuperSu + has MagiskHide for AndroidPay/Snapchat/SafetyNet checks):
https://forum.xda-developers.com/apps/magisk/official-magisk-v7-universal-systemless-t3473445
That is it, done!
