Flashing a GSI

So I followed the steps here to get TWRP on my phone and then flash the unofficial lineage OS ali on my motorola g6 and I got it done but it's not booting into the new OS but instead TWRP. How do I get rid of TWRP so that I can use my new system image?

Removing a recovery is always a bad idea and if you want to try a custom ROM you can always go for phussson's treble builds
I myself use AOSP 8.1 [V25] and it seems to be a daily driver material.
Either way if you want to remove TWRP, you can flash the stock recovery via fastboot.

You might have not cleared the PCB properly when you formatted data. You don't get rid of your recovery. While in TWRP have you tried selecting reboot system. Or reboot bootloader and then in bootloader select start.

bootloop after flashing magisk 18 - PIXEL 3

went through the tutorial and everything went fine until magisk installation. stuck on loading screen forever. only complete wipe\installing twrp img helps to restore the system.
but then no root of course.

Could you provide information about your current setup as well as steps you performed to flash Magisk?

@topjohnwu have previously mentioned that it might not be a good idea to have TWRP installed along with Magisk on A/B devices (since the recovery is in the boot image). Use fastboot to boot TWRP and then install Magisk leaving the stock recovery untouched.

I have solved it by reinstalling stock os, and then when installing twrp and magisk , I didn't check "install twrp as system app" , as it suggests at the end of flashing . Bam , now I have twrp recovery and rooted phone .

[James] Moto E5 Play won't boot into Custom ROM(s)

Device variant: XT19121-2 James
Chipset: MSM8920
After repeated failed flashes I am on stock firmware using this guide. Phone boots and works normally right now, but I can't seem to flash any Custom ROMs on to my phone. I was using this post to flash Lineage OS 15.1, which worked successfully at first, but the WiFi wasn't working so I reflashed it. It still didn't work so I did it again, wiping Dalvik/Cache too. After the second flash attempt, my phone began to only flicker on and off. I made sure to always clean flash, factory resetting, wiping Cache and Dalvik, even formatting data, but no matter what I do it doesn't work. Also attempted other GSI images (arm, A-only) like AOSP, ResurrectionRemix and phhusson's Lineage OS 15.1 But they all failed too. I am using TWRP for James v 3.3.1 although I did also try other TWRP images like v 3.2.1 . But it makes no difference. Also used Magisk v19 like some guides suggested but whether I have Magisk or not, it doesn't work. Even made sure to push the fstab.qcom file to /vendor. Anytime a Custom ROM is flashed whether zip or GSI img it goes past the initial "bad key" or "N/A" screen and starts flickering on and off. Bootloader and TWRP works fine, but that's about it. Everytime a flash fails I go back to stock firmware (which always works) and try another ROM. I wonder why the first attempt worked but doesn't anymore even if I mirror the exact steps I took from stock. If anyone has any solutions I would be really grateful. Let me know if you need any more information.

have you taken any recent OTA updates?

Nope. Still on the 8.0.0 version the stock firmware comes in.

Okay give this a try, I'm assuming you have old root access and TWRP installed.
Download any Android 9 GSI of your liking, boot to TWRP.
Do a complete nandroid backup of the stock firmware.
Do a factory reset then wipe system partition.
Next flash your GSI that you downloaded to your system partition.
After flashing is complete of the GSI reboot to recovery.
After reboot completed flash your open Gapps zip. Then reflash Magisk.
if you get a error message when flashing g apps then you will need to use magic g apps with magisk as it will install them systemless. I have to do this on my device because the partition doesn't have enough space.
Give that a try and let me know how it goes if you have any questions feel free to ask.

I also just noticed you are using the latest version of TWRP 3.3.1. I'm not sure if you originally rooted and installed TWRP with the original patched version by Cody or not, but if so make sure with the new version that you format your data partition to f2fs. As this will ensure correct mounting of the data partition.

Followed these steps exactly, including formatting the data partition to f2fs, and the same problem still persists. Screen just keeps turning on and off in a loop without booting into the ROM. I downloaded the Lineage OS 16.0 GSI A-only Arm version for reference.

I am having the same issue
Using XT1921-1
Latest TWRP
Have tried LOS 15, LOS 16, AOSP 8.1, AOSP 9.0
Have tried flashing in fastboot and TWRP
Have tried every combo of wipe/factory reset/format data and magisk flash possible
have tried stock recovery, have tried no verity, have tried stock boot.img
nothing works. only able to produce powered on (black and blank) screen that turns on and off for a minute before returning to bootloader
PLEASE HELP
think i might need a 8.0 GSI but cant find one anywhere

I eventually got RR to boot on the james xt-1921-3 I installed XT1921-3_JAMES_T_MPCS_8.0.0_OCPS27.91-150-5-1-3_cid21 as a base, then used boot and vendor partitions from JAMES_T_OCP27.91-51-4_cid21_subsidy-TMO_RSU_regulatory-DEFAULT_CFC and it finally worked.

Message me, I'll host a TWRP backup for the XT-1921-3 that boots RR 6.1

Download the file from this post https://forum.xda-developers.com/android/software/universal-dm-verity-forceencrypt-t3817389 , then using fastboot, flash the vendor and boot img
fastboot flash vendor vendor.img
fastboot flash boot boot.img
then boot into recovery and flash the file from that post to disable dm-verity and force encrytion, after that flash magisk, then reboot to bootloader, at command prompt-
fastboot erase userdata
fastboot erase cache
fastboot reboot
that should get you booted - profit

TWRP gets replaced by stock recovery

Thanks

You need to flash Magisk after flashing TWRP
1. Flash Latest TWRP
2. Reboot to TWRP
3. Flash Magisk
If you boot in to system after flashing TWRP, TWRP will be removed

Hey thanks that worked.
But everytime I boot to system and boot to twrp the data gets encrypted and I can't access the files do you happen to know any solution for this?

If you are on stock Rom, according to my knoweldge it is not possible to remove encryption, if you format your date in twrp for removing encryption then reboot to system you can see that the phone is again encrypted.
But in custom roms this doesnt happen.

You don't have to flash Magisk after flashing TWRP. The two are unrelated.
After flashing TWRP you have to boot into recovery, not system. Once TWRP was started, you can reboot into system. No need for Magisk (unless you want Magisk anyway).

It will not work in stock ROM, if you flash a custom rom there is no need to flash Magisk.
You should flash Magisk or custom kernel after flashing TWRP otherwise it will be erased.
Google about TWRP erasing after reboot you should get too many posts regarding this
This is one of them

I am using stock ROM, and yes, also Magisk (installed later). IIRC Magisk is not needed for TWRP to work. When I receive the next OTA notification, I will test this.
The thread you are referring to is for a OnePlus 3T. For our device this is the thread: https://forum.xda-developers.com/moto-g5s-plus/development/recovery-twrp-3-1-1-r7-t3694910.
Since there is no official TWRP for the Moto G5S Plus, I took the following text from the TWRP page for the Moto G5S.
Note many devices will replace your custom recovery automatically during first boot. To prevent this, use Google to find the proper key combo to enter recovery. After typing fastboot reboot, hold the key combo and boot to TWRP. Once TWRP is booted, TWRP will patch the stock ROM to prevent the stock ROM from replacing TWRP. If you don't follow this step, you will have to repeat the install.

Instead of that you can also use fastboot reboot-bootloader, and then from the bootloader start recovery.

Two days ago I received a notification for an OTA update, containing the August 2019 security patches.
After going back to stock ROM, installing all the updates up to the latest, I installed TWRP. After booting into recovery, and then into system, and recovery again, TWRP was gone. Strange, I don't remember this happening before. Maybe I always installed Magisk before booting into system.
Bottom line: you were right, I was wrong. Thanks for pointing it out.

As like you said this is the first time in my life i need to flash magisk to stick twrp.
I usualy doesn't use root or custom roms, install twrp, remove unnecessary apps from stock system, replace host files with adaway hosts, replace or edit gps config files. and continue using stock.
This is the main routine from Android 1.5
(Samsung spica (i think it was the first Android phone from Samsung)).
It may be due to security reason stock kernel or system delete twrp.
When installing magisk it patch stock boot image, that may be the reason of twrp remains after flashing magisk.

Lineage 16.0, Magisk gone after Rom-Update and decryption fails in Recovery...

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.
