Can't install TWRP, no bootable A/B slot - Moto G6 Plus Questions & Answers

Dear all,
after trying to install TWRP (from the official homepage), the bootloader logs show the following message on my phone (moto g6 plus):
AP fastboot Flash Mode (Secure)
No bootable A/B slot
Failed to boot Linux, falling back to fastboot
Fastboot reason: Fall-trough from recovery boot mode
Any recommendations, what I can do/try now?

With volumen keys search for a green letters "Start" and flash stock rom or flash boot.img from stock.
Kepp in mind that Official TWRP can't be installed only BOOTED so don't try it again there's a flashable TWRP installer here:

KEEP IN MIND THAT WE CAN FLASH THE INSTALLER BUT ISN'T RECOMMENDED!

DON'T DO WHAT YOU WANT when a script is given from the creator IT IS NO A PROBLEM.
I know muy words are so really bad but is the truth. Reflash all the stock system and after it BOOT twrp is you need but dont flash cause we don't have a recovery partition, so, we can't use twrp like un older moto phones

Lost recovery, cant boot, only fastboot

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

OnePlus Two stuck on boot logo after trying to boot into recovey on OOS 3.0

.....flash recovery recovery.img

BROTHER ...!!! i am having problem with recovery mode not able 2 boot into twrp recovery .....
You need a custom twrp recovery because they changed the bootloader. I downloaded it from the Oneplus forum, but i'm sure it is also available at XDA
@_Beni_ does that twrp booted ?
@Veer1080 yeah it does boot with this recovery https://www.androidfilehost.com/?fid=24459283995297945
Just flash it via fastboot(fastboot flash recovery recovery.zip)
SuperSu for oxygen is available here:

Use modified twrp
Flash it via fastboot
N then command
Fastboot boot recover "modi twrp name"
Sent from my ONE A2003 using XDA-Developers mobile app
after following these steps i got my twrp working but flashing any rom with it make me stuck at one plus one logo. Now i dont know what to do??
In case you want to go back and use any ohter rom after Oxygen 3.0 instalation.
Oxygen 3.0 it modifies the recovery behavior, you will need to downgrade the OS to version 2 (it will cause the stuck in the logo), once done that, reinstall the TRWP (not modified) via fastboot and now you will be able to flash any other rom

I don't have this device but, your best bet is to take a look at the following thread and post your question within it that's specific to your device.

Boot do not flash
Please do Not try installing TWRP as it is unsupported for now. Simply have to boot the TWRP.
Fastboot boot TWRP.img
I hope this changes but for now we need our pc.

New to device:
do that mean.
we must not!
install the version 3.2.3.0
from the official TWRP homepage ??
No, no.. Reboot to bootloader and use this command. fastboot boot TWRP.img
We need a pc for this.
Our development still working on this. For now do not flash anything to the boot partition.
This device uses the a-b slots and does not have a recovery partition as before, the recovery is now part of the boot.
Use
fastboot boot twtp_every_xxx.img
You can install TWRP on this device and it's very simple!
First boot TWRP via fastboot boot twrp.img and then flash the TWRP-Installer.zip in TWRP. This overwrites the stock recovery which is within the boot.img now for A/B devices. After that you have to flash the magisk.zip and it's done!
Just use Google to find twrp-installer.zip/evert

This installer has been around awhile and there is a reason the official twrps that are far newer cannot be installed yet. While it may seem like it works on the surface, this causes errors in the kernel itself if memory serves me right. This method is not advised! Hopefully, we are on the verge of a breakthrough on a proper official version that can install.

Restoring stock from laf on H918

Hi
I used this method to install LOS 15.1 on my H918. But now i have to restore the stock os on it.
The normal way would be to restore download mode from recovery/twrp and use LGUP to flash a kdz.
The Problem is, that i don’t have twrp on the recovery partition. Using the above guide you install twrp to the laf and flash twrp to recovery from there. But flashing the recovery never worked so i used the laf/twrp to flash LOS.
I have several ideas, but i’m unsure which one would work:
Use the stock recovery, as it’s still on the recovery partition
Reflash the laf/downloadmode from the laf/twrp itself
Reflash downloadmode via adb shell
Btw: The phone is on ARB1

If you used laf exploit then twrp is on the laf partition (download mode) boot into it and twrp should load, from within, flash twrp as an image and point it to recovery. To restore download mode go to the lafexploit thread there's a zip to restore the laf partition

Like i said, that is exactly my problem. Flashing twrp to recovery did not work. It will flash without error, but then boot the old recovery. That’s why i’m asking what other options i have.
