OK so phone was rooted with twrp installed. decided to update to latest ota 30b only I wiped and just flashed boot file and supersu without the actual rom. I know. now the phone goes straight into fastboot mode... I would think twrp is still installed but dont seem to be able to boot into it. I had adb and fastboot on my pc from before but havent used this in some time. if I try to open either of these the command window pops up and quickly closes.. What can I do ?.
new info: fadtboot is working in fact i have wrote a twrp recovery but still cant boot out of fastboot... adb device not listed. i reinstalled minimal adb and fastboot. help
Guys... when i tried to flash oos 3.0 on my op2 through twrp, i first wiped the data to install new rom, then install oos 3.0, it failed. I then flashed the recovery i downloaded from the thread, then restart the recovery
I cant boot into the recovery.
System can't boot
Is it called "brick"?
So i tried to flash stock recovery in pc by command, but it says "remote: device is locked. cannot flash images". any solution to this problem?
I can boot into fastboot mode
You need to run the phone in Qualcomm mode on a PC and run the recovery tool to fix you bootloader.
I did the same and it was a royal ball ache trying to find out how to fix it
Don't do what rosswaa said
Why not?
What you should do is boot your phone into fastboot mode, connect it to your pc. Flash this modified TWRP recovery img to your phone https://www.androidfilehost.com/?fid=24459283995297945. After that you have to flash this modified SuperSU (through the new recovery) https://www.androidfilehost.com/?fid=24459283995297946.
The normal recovery doesn't work in OOS 3.0 (just like in HOS) and it's the SuperSU that gives you the soft brick. A dirty flash of the modified SuperSU should fix it.
I also had your problem and I did what rosswaa said which shouldn't be necessary (I lost all my data and backups).
I didn't lose anything, but I tried doing what you said and my bootloader was screwed so wouldn't take a flashed recovery or anything (yes the modified one)
Wish I hadnt been so excited and just flashed but all sorted now
Hmm okay, if it doesn't work with flashing the new recovery img then do what rosswaa said and after that follow this post https://forums.oneplus.net/threads/installation-instructions-faqs-oxygenos-3-0-0.439108/
Obviously try what green says first, if it works then happy days
first i am really glad that someone give some advices on me. But since i am a noob, how can i flash twrp in fastboot mode? using command? "fastboot flash recovery xxx.img"? thx

I was trying to root my phone, i got TWRP recovery for my device (i'm sure it is).
I opened odin and checked the OEM Unlocking in Dev Options , connected my device and everything worked fine. But when i boot into recovery it shows that i still use the stock one.
What's the problem?
In my opinon the bootloader is Locked i'm not sure. also i tried to see if it is locked or not but i couldn't because fastboot devices command didn't work for me although i'm sure i installed ADB and Fastboot And my devices drivers correctly.
Note: adb devices works for me only the fastboot.
Please guys i need your help!
Bear with me, I had an older version and maybe just my method but I had messed up the custom rom I had on so I went to put a new one on and wanted to update TWRP at same time.
I installed the new custom rom, then installed TWRP and correctly clicked recovery.
However now recovery just goes into fastboot mode, I went into the dev settings and put usb debugging on, authorised it but each time it goes into fastboot it is not recognised and when I reboot into phone usb debugging has been disabled.
So now I can't get into recovery to flash a new rom, nor can I put twrp on by fastboot.
Stuck at what to do
Using Havoc OS
Try booting into the recovery from fastboot
Boot into fastboot and type
Fastboot boot recovery.img (recovery.img is the file saved on your pc)
I was on an older version of LOS17 I think and tried to flash LOS19.1 and MindtheGapps and now the phone is stuck on the twrp loading screen (twrp version 3.4.0-0). I have tried to access it via adb and adb devices shows the device code in 'recovery' and fastboot does not show any device.
Any suggestions out there would be hugely appreciated! Its essentially a brick at the moment
Cheers!
EDIT: It was not being recognized in Windows (bad driver). Fixed that and then fastboot continue worked. Proceed as normal.
flash the stock recovery and lock the oem then unlock it....
and then reflash your twrp version.
