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

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

Does anyone receive the update with September patch via OTA after back to stock following post #5 instructions?
This a fantastic guide - THANKS!!! - I have linked to it giving credit. Thanks!
I have also a thread, if you follow that one. Bootloader is locked/ u will be able to get ota'$
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 - 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.

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?
Regards

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.

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.

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.
For future use or other versions like OOS EUROPE,INDIA, etc. , you can patch your own boot.img with my tool here
But for now just follow the instructions
Boot.img patched with MAGISK 20.4 on OOS 10.0.14 HD65AA (GLOBAL)
Only for OOS 10.0.14 Global!!!!
Enjoy!
Instructions:
reboot to fastboot
Code:
adb reboot bootloader
Code:
fastboot boot magisk_patched_10_0_14.img
let it boot and check if u have root
if u got root then reboot to fastboot again
Code:
adb reboot bootloader
Code:
fastboot flash boot magisk_patched_10_0_14.img
When finished type
Code:
fastboot reboot
patched boot.img download: https://drive.google.com/file/d/1wZ2TyIi0uUfbRTxPYK_imURBVjHqaA_f/view?usp=sharing
stock boot.img download: https://drive.google.com/file/d/1R90vvdJEe6NkL2FdqSvuxtk18SmWHYUc/view?usp=sharing
It's still telling me "Root access is not properly installed on this device". I have an unlocked bootloader and OOS 10.0.14 HD65AA (GLOBAL), is there something I'm missing?
EDIT: tried a different root checker and I'm fine. Please disregard.

Thank you for the information
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

Thank you, I'll dig into these links!
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?

Make sure you have the latest full platform tools and not the minimum platform tools, or if you are on a windows PC try the fastboot enhanced version

You could try:
fastboot set_active other
Or
fastboot set_active a
Or
fastboot -a (this is in the documentation but I have never tried it, nor see it online often)

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

Spent some time trying to do this. fastboot said Rewriting, Sending, writing, Finished. All OKAY. No error messages in there. But when I rebooted into the other partition I got the same dm-verity crash dump.

I dug a bit further and tried these as well:
Code:
fastboot --disable-verity --disable-verification flash vbmeta_a vbmeta.img
fastboot --disable-verity --disable-verification flash vbmeta_system_a vbmeta_system.img
fastboot --disable-verity --disable-verification flash vbmeta_vendor_a vbmeta_vendor.img
Whenever I try to boot to the a partition, I just loop back into fastboot mode. The b partition still works though.

Fastboot --set-active=a or b which ever you need in bootloader mode

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.

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.
If not, #19 above
