Our old twrp have been great compared to nothing but it isn't exactly fully working and freezes a lot on splash screen.
Thanks to @Stricted and @deadman96385 we now have a more functional twrp.
Support for A/B slots.
ADB working.
No need to flash full firmware. Just flash the vbmeta_patch.img and boot twrp.
!!BOOTLOADER MUST BE UNLOCKED!!
YOUR DATA WILL BE WIPED!!
Code:
fastboot flash vbmeta vbmeta_patch.img
fastboot boot twrp-3.3.1-test3.img
Now that we booted to TWRP it's time to format data.
Go to wipe -> format data -> type yes.
"Permanent" install of TWRP (optional):
Copy "twrp-3.3.1-test3.img" to your device.
Boot "twrp-3.3.1-test3.img" from fastboot and go to advanced settings.
Use the option to install recovery ramdisk. In the "file manager" you pick the "twrp-3.3.1-test3.img"
This will extract the twrp ramdisk and install it to your boot.img.
When it's done, tap the "fix recovery bootloop" in advanced settings so that it won't reboot to recovery instead of system..
Since this replaces the ramdisk in boot.img you'll have to reflash magisk afterwards if you want root.
This must be done every time you update your boot.img.
-------------------------------------------------------------------------------------------------------------------------------------------------------
# ROOT:
-----------
# First time:
# Method 1: Root, forced encryption disabled. Full access to data from twrp:
Flash Magisk and Disable_Dm-Verity_ForceEncrypt.zip.
# Method 2: Root only. Device still encrypted and won't be able to decrypt / mount data in twrp.
Magisk modules through Magisk manager still works:
Flash only Magisk.
----------------------------------------------------------------------------------------------------
# Fastboot flash update without loosing root or data:
----------------------------------------------------------------------------------------
# Already rooted with encryption disabled:
Extract the firmware zip to your adb/fastboot folder.
You already have the patched vbmeta flashed so just remove the stock vbmeta.img from the folder after extraction to avoid flashing it by mistake.
Flash full firmware without wipe. (Use cmds from below. Save as .bat to make it more simple.)
Boot twrp and then install it, fix recovery bootloop.
Reboot recovery, flash Magisk and Disable_Dm-Verity_ForceEncrypt.zip.
Boot system.
Code:
echo off
echo - UPDATE AND PRESERV ROOT -
fastboot flash pit diskmap.pit

echo TWRP is booting..
echo - install recovery ramdisk, fix bootloop, flash magisk & dm-verity zip.
echo - alternatively flash only magisk and Disable_Dm-Verity_ForceEncrypt.zip if you want to keep stock recovery.
pause
# Already rooted with device still encrypted:
Flash firmware update, except vbmeta.
Boot twrp and flash Magisk with adb sideload.
(alternative method: boot twrp and flash magisk patched boot.img)
Download TWRP: https://images.stricted.net/test/troika/twrp-3.3.1-test3.img
Download Magisk: https://github.com/topjohnwu/Magisk/releases
Download vbmeta_patch.img & Disable_Dm-Verity_ForceEncrypt.zip attached below.
PLEASE, DON't QUOTE THE WHOLE OP.
Great guide @tys0n and thank you to @Stricted and @deadman96385 for his work !

My Vision is already unlocked and rooted by the old TWRP method. Should I just do this step so I can update to the new TWRP, and then I can follow "encryption disabled" steps to update to a new firmware?
I suppose I can't enable encryption anymore without resetting data.

You're right. You can't switch between encrypted / non encrypted without a reset.
This update method have been working for me with the old twrp as well, but this new build is much better and more stable that I see no reason not to switch to the new one.
Actually, I think it may be better to first fastboot flash the new firmware (except vbmeta) so that you have a "clean" boot.img to start with if you're planning to use the install recovery ramdisk. At least if you have the old one installed already.
That's how I switched and I've had no problems.
Worked to my, Thnx
Good afternoon,
I'm trying to "patch" the TWRP as you indicate at the beginning of the first post.
When you say:
"For permanent install, use the" flash recovery ramdisk "option in twrp advanced settings"
What file do I have to flash?

Sorry, I could have been more clear about this step in the description.
Copy "twrp-3.3.1-test3.img" to your device.
Boot "twrp-3.3.1-test3.img" from fastboot, go to advanced settings.
There's an option to install recovery ramdisk. In the "file manager" you pick the "twrp-3.3.1-test3.img"
This will extract the twrp ramdisk and install it to your boot.img.
When it's done, tap the "fix recovery bootloop" in advanced settings.
Since this replaces the ramdisk in boot.img you'll have to reflash magisk afterwards if you want root.

Good evening,
One last question:
Currently I have permanently installed the TWRP.
Is it also necessary to do these last steps that you have added?

Bootloop
Dude, my phone was encrypted and unrooted. I flashed vbmeta then booted into twrp. Then I flashed twrp using the ramdisk method, then I clicked to patch the recovery loop, then I flashed Magisk then I flashed the Disable DM Verity. Now I'm stuck in a recovery loop. The phone turns on, then android one screen, then reboots then goes to twrp...
What did I do wrong / miss?
"Then I flashed twrp using the ramdisk method, then I clicked to patch the recovery loop."
Agter this restart the phone in recovery mode and then continue as explained.
Sorry in bad english
First of all, @tys0n thank you very much for your work. I got this phone for work, but since an unrooted Android device is almost useless to me, this is very much appreciated. Just a few annotations from my side, maybe they help someone.
1. Permanent TWRP install didn't work for me. TWRP was installed sucessfully but just like the dude above me, it would not boot to system, even after appying the bootloop fix. I had to reflash to fix this, so better be careful here!
2. I didnt want to lose encryption, so i chose method 2 for rooting. This works fine, but still I had to wipe data in the first place. Otherwise it would again not boot to system, but at least this time it told me that wiping would possibly fix this. However, after wiping encryption IS active. Maybe I did something wrong here but I don't know... Chosing method 1 seems to be the more straightforward option here.
3. Despite these issues, flashing updates seems to work just fine as described described in the OP, preserving data and root. I have only tried this once, from QSA30.62-24-6 to QSA30.62-33, which is currently the most recent patchlevel for RETEU devices. I even got the "successfully updated" notification afterwards, as if it was an OTA update

Hi. Yes, you're right. After flashing the patched vbmeta we need to format data. I've made it more clear in OP now.
Thanks for pointing it out.

Format data in twrp
It doesn't work for me (XT1970-1).
I did the process according to information method 2.
the system boots normally.
however magisk is not 'GREEN' like two pieces of information.
How is it going without ROOT, how do I put ROOT?
have another process after this information?
Thank you.
It worked.
I performed the process again.
and everything went well.
Thanks to everyone involved. :good:

Just a quick question, when I have TWRP and root I can't pass the SafetyNet check, right?
Hello all. When I click on Internal storage, there are folders with names like "a16sgyx462" and so on, so I am not able to install TWRP permanently. Can somebody help me with this?

You probably have Data encrypted. You need to execute Format Data in TWRP.
Has anyone used the official TWRP version? I've been thinking of transitioning from the older, unofficial, TWRP to that, but I haven't found any comment about it at all.

How to go from Lineage OS 14.1 to stock? (Updated with the process & latest links)
I am currently on lineage OS 14.1 (7.1.2) dated 18.09.2017.
I want to go back to stock firmware as I am facing some issues with lineage.
How to find the latest firmware. Found this website which has all the images https://firmware.center/firmware/Motorola/Moto Z Play/Stock/XT1635-02/
But I am unable to select the correct one for my device. (do not want to brick it). Also found another thread stating latest firmware
https://forum.xda-developers.com/moto-z-play/help/addisonnpns26-118-22-1cid50subsidy-t3675521
I am an Indian MOTO Z Play
Is there a way to go full stock and also start to receive OTA updates. Can someone provide me with full guide with links?
First you need exactly your software channel and the build of your baseband and bootloader. You know how to get this information?
After a lot of tries, finally was able to go back to stock. Will be compiling a guide for other to follow with links.
On latest 7.1.1 with August patches.
Is there a problem with audio fx,
Even viper4android not working.

Process to go from custom rom back to stock (August update)
There are several guides on going back from custom rom to full stock, but still I made this guide with latest links. I just went from LOS 14.1 back to full stock. Below is the step I took:
1) Download and install minimal ADB AND FASTBOOT
I used version 1.4.2 which is the latest version https://www.androidfilehost.com/?fid=745425885120698566
2) Download and install motorola drivers
https://motorola-global-portal.custhelp.com/app/answers/detail/a_id/88481
3) Download the latest firmware
I used ADDISON_NPNS26.118-22-1 which has august security updates https://www.androidfilehost.com/?fid=673368273298986785
4) Extract the zip file (firmware) and move all its contents to the folder where you have installed minimal adb and fastboot
5) Create a text file, add the following text to it and save it as "launch.bat" in the same folder.
echo off
fastboot getvar max-sparse-size
fastboot oem fb_mode_set
fastboot flash partition gpt.bin
fastboot flash bootloader bootloader.img
fastboot flash modem NON-HLOS.bin
fastboot flash fsg fsg.mbn
fastboot flash dsp adspso.bin

6) Switch off your phone and open it in fastboot mode (press power and volume down button for few seconds after phone as switched off)
7) Connect your mobile to your computer
8) Click on the launch.bat file that you saved and it will install stock firmware on to your mobile. It will take a couple of minutes. (It will wipe everything on your mobile so take a backup of your important data)
9) Once the process is complete, it will ask you to enter any key, after which it will reboot itself.
Once rebooted, you will have full stock, non rooted, and latest firmware with august patches.
Is this works with European version of Moto Z Play? Like I bought it from France. Thanks.
And can we do OTA updates after doing this?
Thank you so much for this guide, my phone was rebooting to recovery every single time and nothing worked. I flashed this rom as you said and my phone just booted and it's working. I can't believe it.

My phone is reteu and after flashing is still on reteu, so it should be fine, dont worry. Also you should get any future updates via OTA.

Thanks a lot for this guide! Just wanted to ask if it's safe and stable to root this and pass safetynet check.
Thanks for you time
Only way to root and still pass safetynet is via magisk
But unfortunately it needs a custom kernel with f2fs fix. However with 7.1 update motorola fixed it but broke some other things.
There is not a custom kernel for 7.1, so till then no way to root and have safety net.
But you can easily root via magisk

Hey guys! Need some help.
I've been trying to flash a Android Pie ROM on my device and I have no success.
The problem is, after flashing the rom and TWRP Zip the device reboots twice then boots back into TWRP.
Then all the files on the device has random letters and numbers (i.e. ckjrdh574o0hmdu749y7nv)
Why can't I flash a Android Pie rom successfully?
I am on the latest Android Pie update. (Flashed on both slots)
Here is my steps:
Flash stock rom on both slots
Boot up in stock rom. (no set up, no password, no pin, nothing totally skipped setup)
Place files on device (Rom and twrp.zip)
Reboot into Bootloader
Boot into latest TWRP using fastboot
Once in Twrp, slide slider to allow modification to system parition
Factory reset/wipe data (and all that)
Flash rom (I tried Carbon Rom 7 and lineage os 16)
Flashed twrp zip
reboot
After the system reboots twice I am back in twrp and all the files and folder have numbers and letters as files names.
Any idea as to why this keeps happening?
How can I fix this?

Not sure if Carbon / Lineage has special install instructions or not, but you can follow the initial 9x setup in the link in my sig, then follow cust Rom installation process.

Nothing to special from the norm. I didn't everything the forums told me to do.
Okay definitely, I'll check that out and try those steps.
Also do you think I have a phone that twrp can't decrypt? I remember a while back doing one of the twrp updates that some phones won't decrypt because it used the older encryption method or something like that and TWRP was only able to decrypt then phones using the new method or something like that.
Oh and another question, do you guys think I should root the stock image with magisk then boot into twrp using fastboot and install the room then the twrp.zip?
My question would be do you have other details you might have overlooked? For example, at the end of flashing, TWRP would usually ask whether you want to install their app. Did you install it or did you skip it?
Also, what was your exact procedure in flashing stock rom to both slots? I have also messed around with custom roms and reverted back to stock using the following:
Return to Stock:
Source of this knowledge is Method 2 of this video.
#flashing bootloader to slot A and slot B
Code:
fastboot reboot-bootloader
fastboot flash bootloader_a bootloader[...].img
fastboot reboot-bootloader
fastboot flash bootloader_b bootloader[...].img
#flashing radio to slot A and slot B
Code:
fastboot reboot-bootloader
fastboot flash radio_a radio[...].img
fastboot reboot-bootloader
fastboot flash radio_b radio[...].img
#set active slot to B, flash system image
Code:
fastboot --set-active=b
fastboot reboot-bootloader
fastboot --skip-reboot --skip-secondary update image[...].zip
#set active slot to A, flash system image [different command!!!]
Code:
fastboot --set-active=a
fastboot reboot-bootloader
fastboot --skip-reboot update image[...].zip
Now straight from the bootloader, boot into recovery.
Wipe data/factory reset.
Let it reboot back into android.
Then, I followed the install instructions in the twrp thread to get custom recovery back onto my device. (If you want rooted stock android, flash it from twrp and then install the latest magisk manager apk.)
Now just find another custom rom and follow the install directions from that thread.

Now that's all the steps j took to flash the roms.
I do not install twrp app I skip that.
My first methond to flash stock on both slots is set slot to a then flash stock using the flash all bat file in from the stock images (google directions to flashing images)
Then it would reboot. Then I would set to slot b and flash the stock images the same way using the bat file.
Then I found out that wasn't really the best way to do it so I used deuces (I believe that was the users name) bat file to flash the stock images on both slots the correct way and that's what I've been doing since.
But your steps have a different step then what I do. It seems it does the same as deuces bat file however once it's done I just boot straight into stock rom. I dont boot into stock recovery and factory wipe. But I will definitely try that as well.
Finally fixed it!
I flash both slots and followed everyone's directions.
The problem was I wasn't wiping all the things I needed too.
I read in another roms steps to not only do the factory reset thin in TWRP, but to also manually wipe system, data, dalvik/art cache. Then flashed the room and TWRP.zip.
I did this and BOOM, I booted up into the room! Thanks again for everyone's help!

My question would be do you have other details you might have overlooked? For example, at the end of flashing, TWRP would usually ask whether you want to install their app. Did you install it or did you skip it?
Also, what was your exact procedure in flashing stock rom to both slots? I have also messed around with custom roms and reverted back to stock using the following:
Return to Stock:
Source of this knowledge is Method 2 of this video.
#flashing bootloader to slot A and slot B
Code:
fastboot reboot-bootloader
fastboot flash bootloader_a bootloader[...].img
fastboot reboot-bootloader
fastboot flash bootloader_b bootloader[...].img
#flashing radio to slot A and slot B
Code:
fastboot reboot-bootloader
fastboot flash radio_a radio[...].img
fastboot reboot-bootloader
fastboot flash radio_b radio[...].img
#set active slot to B, flash system image
Code:
fastboot --set-active=b
fastboot reboot-bootloader
fastboot --skip-reboot --skip-secondary update image[...].zip
#set active slot to A, flash system image [different command!!!]
Code:
fastboot --set-active=a
fastboot reboot-bootloader
fastboot --skip-reboot update image[...].zip
Now straight from the bootloader, boot into recovery.
Wipe data/factory reset.
Let it reboot back into android.
Then, I followed the install instructions in the twrp thread to get custom recovery back onto my device. (If you want rooted stock android, flash it from twrp and then install the latest magisk manager apk.)
Now just find another custom rom and follow the install directions from that thread.

I stumbled across this post after having several issues trying to get my Pixel 2 XL flashed with a custom ROM (constantly resulting in boot-loops), and the steps worked perfectly.
I've ended up running these steps several times today, but I like keeping all of my stock images in sub-folders by release date. I'm not the greatest Powershell guru, but I've written a script that will search sub-directories in a folder for dates, and select the latest date and automatically flash the radio, bootloader, and image from that directory using your steps.
Code:
clear;
# Execution Policy must be adjusted in order to obtain the current executing directory of the script. This is a one-time command that must be run separately.
# Set-ExecutionPolicy RemoteSigned
# To reverse the command set the execution policy to restricted:
# Set-ExecutionPolicy Restricted
# The root directory which contains date sub-folders in the format yyyy-MM-dd representing an extracted OTA zip.
$startingDirectory = split-path -parent $MyInvocation.MyCommand.Definition;
# Alternatively, hard code a starting directory.
# [System.String]$startingDirectory = 'D:\Flashing\Roms\Taimen\Stock\';
[System.String]$targetFolder = (Get-ChildItem $startingDirectory | Select-Object -Property @{Name='Date';Expression = { Get-Date $_.Name -Format 'yyyy-MM-dd' }}, @{Name='FullName';Expression= {$_.FullName}} | Sort Date -Descending | Select -First 1).FullName;
if (-not $targetFolder) {
throw 'No folders are located in directory ''' + $startingDirectory + ''' with the date format yyyy-MM-dd.';
}
[System.String]$bootloader = Get-ChildItem $targetFolder -Name 'bootloader-*.img';
[System.String]$radio = Get-ChildItem $targetFolder -Name 'radio-*.img';
[System.String]$image = Get-ChildItem $targetFolder -Name 'image-*.zip';
# Validate all files have been successfully located.
[System.Collections.Generic.List[System.String]]$messages = [System.Collections.Generic.List[System.String]]::new();
if (-not $bootloader) {
$messages.Add('The bootloader file was not located.');
}
if (-not $radio) {
$messages.Add('The radio file was not located.');
}
if (-not $image) {
$messages.Add('The image file was not located.');
}
if ($messages.Length -gt 0) {
throw 'Unable to locate files in path ''' + $targetFolder + ''':' + [Environment]::NewLine + [System.String]::Join([Environment]::NewLine, $messages);
}
$bootloader = [System.IO.Path]::Combine($targetFolder, $bootloader);
$bootloader;
$radio = [System.IO.Path]::Combine($targetFolder, $radio);
$radio;
$image = [System.IO.Path]::Combine($targetFolder, $image);
$image;
#adb reboot bootloader;

Hi
I was trying to install Lineage OS on my device, but I failed, now the phone does not have TWRP anymore, and when I power up, it goes into fast boot only.
I have done quite a lot of work to save my phone, and the last thing that I did was download the stock fastboot rom and run flash_all.bat from it.
(I can not get the Miflash tool working on my PC because when I startup the program, it asks me to download 5 drivers, but it failed to download and throw me an error)

First of all - if your phone boots to fastboot, there seems to be a problem with your bootloader or kernel.
To fix that, you need to reflash aboot.img and boot.img via fastboot.
Boot.img depends on the version, you want to install. Copy both files into your fastboot folder and
Code:
fastboot flash boot_a boot.img
Code:
fastboot flash boot_b boot.img
Code:
fastboot flash aboot_a aboot.img
Code:
fastboot flash aboot_b aboot.img
Now your phone shouldn´t stuck @ fastboot anymore.
Ok, to save your data, you could try to boot twrp:
Code:
fastboot boot twrp.img
If you´re lucky, it can decrypt your data - then you can backup data and internal storage...
If it´s not able to decrypt, you need to install twrp.
To install a fastboot rom without miflash look here
I suggest you to install caf-kernel via twrp. Sometimes your phone boots up with it - magic

Just for my knowledge, what are these boot_a and boot_b please? they relate to the two sim slot in this device?

Boot.img from fastboot rom... To be flashed in partition boot_a and boot_b. Our device is a AB-device. That means all partitions are doubled (except of data). If your system breaks, you can switch to the other slot by "fastboot set_active a" or b if you are on a.... Btw perhaps that fixes your phone too! Boot twrp and you can see which slot is active (under reboot)
Hello everyone,
I need help to start on flashing g7 play etc. In the old days I flashed phones like galaxy s3, s4, s5 and Note 4, but I'm not an expert in all of this.
Then I changed to iPhone 6s and now I want to come back to Android.
My goal:
de-googled moto g7 play
Android 9/10 -> would prefer 10
if possible -> root
My Device:
moto g7 play - XT1952-1
(bootloader unlocked)
---
Build number:
PPYs29.105-134-7
---
If have read most of the Threads for the g7 play, but at the moment I'm a little scared to brick it.
I have some questions:
1. I copied together for myself a Instruction (at the end of post). Could you tell me if this is OK like this, or do I have to do additional things before start?
2. In my copied instruction, at the point of flashing the GSI (Instruction ROM: -> Step 1)
What does "Dirty flashing your g7 play" mean? Do I have something additional to do, before following the instruction, or is dirty flashing the following instruction of the post?
3. Modded phh -> I have no information about this, could you explain, or give me link?
4. Overlay -> I have no information about this, could you explain, or give me link?
Thanks for your help

TWRP:
twrp.img

Instruction TWRP:
step 1
Fastboot boot twrp.img
step 2
Copy twrp to your external sdcard, or use adb push twrp.img /tmp/twrp.img
step 3
Go to Advanced > install recovery ramdisk then navigate to tmp or your external sdcard and select the twrp.img you copied
step 4
Use wipe > format > type "yes" to continue then use reboot > recovery from twrp's menus
step 5
Once twrp starts up again, wipe data & system, make sure system is mounted, then flash a GSI. Flash the universal disabler afterwards.
If you get a failed to unmount error, manually mount all partitions and reflash whatever it errored on
step 6
Optional: Flash my modded phh for root. (Install the apk after.) Never use Magisk! It will fail to root, cause a bootloop, or break twrp
FIX navbar on a GSI:
$ adb root
$ adb shell
$ setprop persist.sys.phh.mainkeys 0
$ reboot

First make sure you install the stock OS to both slots, including the bootloader. I forgot to flash bootloader_b, and got stuck in EDL last week. You don't want that to happen and it's not easy to get out of. If you do this first, you will not have to worry about getting bricked.
Use my instructions found here for twrp. Inside the instructions you'll also find a link to my modded phh. Flashing a GSI can be done with twrp or fastboot. You also don't need the dtbo.img anymore since it's embedded inside of twrp. The trickiest part really, is just getting twrp installed. If you're using twrp to install a GSI, wipe system, data, dalvik, then flash the image to system. (You'll get a location prompt.) After installing a GSI, copy the overlay to /vendor/overlay, and set permissions on it to 0644, then reboot. Flash modded phh for root if you're using LOS 16 or 17. I think it's already included in Phh's AOSP builds.
There's also a trick to dual boot your OS. I keep one slot with stock installed, that's debloated and rooted with magisk. The other slot I use for flashing GSIs. Twrp can't restore encrypted data for stock, but you can format /data using "yes" then switch slots and use "reboot recovery" to boot up stock with magisk. To swap back to the GSI, fastboot boot twrp, format data, switch slots from the reboot menu, reboot to recovery. If twrp starts, you changed slots successfully. Then just restore data for lineage and bootup.
Oh by the way, "dirty flashing" is just flashing an OS update without wiping data first. I don't recommend it though. Sometimes bugs from older builds will get carried over. You don't need to do that to install LOS 17 or Android 10. It might've been true at one time, but it isn't now. You can just do your wipes and flash the latest build.
Thanks for your Help
How can I check if both partitions are with stock and bootloader?
Is there a trick to copy a working partition to the oter?
I would flash like it is written in this: [Guide][Channel][Stock]Moto g7 play Factory Firmware Images
(https://forum.xda-developers.com/g7-play/how-to/channel-moto-g7-factory-firmware-images-t3996303)
Would it flash both partitions (if only one is written)?

Typically if you've taken an OTA then you already have both slots filled. You can check with...
Code:
fastboot getvar all
Near the bottom you'll see some slot information. If slot b is active, then you should already be covered. I still think it's best to manually flash both slots though. If you've never updated then slot b is definitely empty. This is what I do...
Code:
fastboot flash boot_a boot.img
fastboot sending image boot_a...
Successful!
Image not signed blah blah something that isn't important...
Hit the up arrow on the keyboard then just change _a to _b
Code:
fastboot flash boot_b boot.img
Same with system, only I run through the list of sparse chunks in one shot, then hit the other slot. Use the big series of sparse chunks (0-7) on both slots. Skip the two that would normally go to system_b.
Code:
fastboot flash system_a system.image_sparsechunk.0
fastboot flash system_a system.image_sparsechunk.1
fastboot flash system_a system.image_sparsechunk.2
etc...
Then on the other side the same way.
Code:
fastboot flash system_b system.image_sparsechunk.0
fastboot flash system_b system.image_sparsechunk.1
fastboot flash system_b system.image_sparsechunk.2
etc...
When you get to oem, do not use oem_other.img, flash oem.img to both slots instead. Basically just make sure you do that with everything. E.g. dsp_b modem_b. I'm sure you get the idea by now.
Hello Spaceminer,
I have little knowledge in working with terminal in debian (I used man fastboot and tried some things like changing slots but this did not work). And then I tried some of these things and was to scared to brick it so I flashed it with RDS Lite (I hate to use Windows ) last night.
With RDS Lite flashing was no problem and I got a OTA, so slots a and b are not empty. After that I used your TWRP-Guide which you linked and it worked
BUT
Then I was trying to flash a GSI (arm32binder64ab):
lineage-17.1-20200309-UNOFFICIAL-treble_a64_bvN.img
Havoc-OS-v3.0-20191226-A64AB-Unofficial.img
system-quack-arm32_binder64-ab-vanilla.img
it completed but failed to boot:
Start Up Failed:
---
AP Fastboot Flash Mode (Secure)
No bootable A/B slot
Failed to boot Linux, falling back to fastboot
Fastboot Reason: Fall-through from normal boot mode
No bootalbe A/B slot
Failed to boot Linux, falling back to fastboot
Boot up failed
---
TWRP is always available with:
fastboot -> recovery
Could you please help me to handle this?
I would really love to use this phone de-googled with root permission cause I'm sad of spying on me by Gafa and the moto g7 play (I hate the size of the bigger ones) looks like the perfect model for me
PS: I have some screenshot's if you need

Hey im in a smiliar situation with the G7 Play (XT1952-2)
I have the same goal of running this phone without google..
I would like to install LineageOS with microG (signature spoofing)
Have you been successful with this? Do you have a A-Z list of instructions for a fellow newbie?
I was rooted with Magisk 25.2 fine. I followed the OTA update intructions (uninstall, update, install to the other partition etc). When Magisk rebooted my phone I got a messae that says
QUALCOM CrashDump Mode
-------------------------------
dm-verity device corrupted
verity_ctr
I can reboot back into my other partition, and I have a version of the OS that's pre-OTA, but I've lost root there. I can switch between partitions and go from the Qualcom CrashDump to my working non-rooted OS.
How do I get from either of these places to a rooted version of the OTA update?
I'd suggest waiting for the next OTA and do it again.
However, I don't understand why you did the uninstall, update, install to the other partition etc part. I usually just do the following steps:
Install OTA (do NOT reboot yet)
Install Magisk in the other partition
Reboot
So far it has worked for me for each update.

You may be able to copy your good partitions (a or b, whichever works) to the other one. So they'll both be loaded with working stock firmware. Then take the OTA and drop in a magisk patched boot image after OTA is good

I got similar problem, solved by disabling dm-verify manually. You can try extract vbmeta.img from rom package using payload_dumper, then use fastboot to disable dm-verify.
fastboot --disable-verity --disable-verification flash vbmeta vbmeta.img
I'm having this same problem, but to fix it I need to switch back to the "good" slot and boot my phone normally to fix it. However after booting my phone into fastboot, I'm unable to run the appropriate command:
Code:
fastboot --set-active=a
fastboot: unknown option -- set-active=a
Do I have the wrong version of fastboot installed on my PC? How can the rest of fastboot work but not this specific command?

Maybe you could try set-active a (if a slot is the bad rom) first, reboot into fastboot again and then use fastboot to flash vbmeta with disable verity parameter.
Or you could try to boot into good rom, and flash full update package using local update instead of ota, then see if it can boot into updated rom.

Or you could try to boot into good rom, and flash full update package using local update instead of ota, then see if it can boot into updated rom.

I did switch the active slot to a, just cause that seemed like a good idea.
How do I only flash the update package to the A slot? I thought it went to both by default?

When you flash tom in the system, it only update the firmware in another slot. So if your current good rom is in slot b, you can just boot into slot b and apply system update via local update, the updated rom will be in slot a.

If you have the images:
fastboot flash system_a system_a.img
fastboot flash system_b system_b.img
it's also possible to pull the whole partitions down with msm tool (press f8, select partitions and readback, files go to c:\) or using dd.
