maybe you can try doing a re-flash, remember make a backup of everything before in TWRP,

If you do not get any results you can try with the latest version of the oreo android

my friend I endeed like you and I fixed.
you need to follow different threads.
first you need to unlock the bootloader to downgrade to nougat and make EFS backup.
download twrp form here: https://forum.xda-developers.com/z2-play/development/twrp-3-2-0-0-moto-z2-play-albus-t3715660
on fastboot install twrp, enter twrp recovery(I dont allow modifications on first boot) and make a EFS backup.
connect to pc to copy the EFS backup to safe place.
download this nougat firmware: https://androidfilehost.com/?fid=962187416754466195
then you need to downgrade to that firmware on fastboot:
fastboot flash modem NON-HLOS.bin
fastboot flash fsg fsg.mbn
fastboot flash dsp adspso.bin
fastboot flash logo logo.bin
fastboot flash boot boot.img
fastboot flash recovery recovery.img
fastboot flash system system.img_sparsechunk.0
fastboot flash system system.img_sparsechunk.1
fastboot flash system system.img_sparsechunk.2
fastboot flash system system.img_sparsechunk.3
fastboot flash system system.img_sparsechunk.4
fastboot flash system system.img_sparsechunk.5
fastboot flash system system.img_sparsechunk.6
fastboot flash oem oem.img
fastboot erase cache
fastboot erase userdata
fastboot erase carrier
fastboot erase DDR
fastboot reboot
once the phone boots to system check if you have 4g lte, imei and fingerprint now works.
now, you need to follow the steps for installing OTA form this trhead: https://forum.xda-developers.com/z2-play/how-to/official-oreo-z2-play-t3784660
when complete and finally boot you notice that you dont have signal this is normal go and check your imei and everthing be there, poweroff and enter recovery and make factory reset.
when boot everthing works signal and fingerprint scanner.
if you want to lock your bootloader you need to download full oreo firmware from this thread: https://forum.xda-developers.com/z2-play/how-to/fastboot-rom-oreo-retail-via-fastboot-t3786153
at least install the full oreo firmware on fastboot with this commands:
fastboot oem lock
fastboot oem lock
fastboot flash oem oem.img
fastboot flash system system.img_sparsechunk.0
fastboot flash system system.img_sparsechunk.1
fastboot flash system system.img_sparsechunk.2
fastboot flash system system.img_sparsechunk.3
fastboot flash system system.img_sparsechunk.4
fastboot flash system system.img_sparsechunk.5
fastboot flash system system.img_sparsechunk.6
fastboot flash system system.img_sparsechunk.7
fastboot flash system system.img_sparsechunk.8
fastboot flash system system.img_sparsechunk.9
fastboot flash system system.img_sparsechunk.10
fastboot flash system system.img_sparsechunk.11
fastboot flash boot boot.img
fastboot oem lock
the phone restarts automatically and you will have full oreo firmware with fingerprint and signal with locked bootloader.
I hope you understand my bad english.

Has this same issue after upgrading to Android Oreo on the Z2 play - fingerprint scanner stopped working. Tried a factory reset but still no go.
What I ended up doing was going back into fastboot, and doing a system wipe before flashing these files:
Code:
$ fastboot -w
wiping userdata...
Erase successful, but not automatically formatting.
File system type raw not supported.
wiping cache...
Erase successful, but not automatically formatting.
File system type raw not supported.
erasing 'userdata'...
OKAY [ 0.151s]
erasing 'cache'...
OKAY [ 0.005s]
finished. total time: 0.156s
Also I have the XT1710-06 model (Latin America), and needed to flash ALL of the files. Radio works fine for me (T-Mo).
After doing the wipe and then flashing all files, the fingerprint reader now works.

how to instal stock oreo after a custom rom ??

i have a 8.1 custom rom and want to upgrade to pie rom
put i have to change into Official Stock Oreo 8.1.0 first (i think !)
so what should i do
please help

As long as your base firmware is oreo (stock oreo was on your device before you flashed a custom rom) you just need to format system data cache & flash another custom rom
If you want to flash stock firmware just download it and flash it with fastboot commands - there's loads of step by step guides if you Google how but here are the commands
Code:
fastboot oem fb_mode_set
fastboot flash partition gpt.bin
fastboot flash bootloader bootloader.img

fastboot flash recovery recovery.img
fastboot flash dsp adspso.bin

You don't use adb to flash stock firmware - you use fastboot
The commands are written above with link to the firmware
I am not going to Google - how to install stock firmware on a moto g5 for you. I'm sure you are capable of doing that and reading the guides for a step by step walk through if you don't understand how to use the fastboot commands written above

Update Android Oreo to Pie with twrp+magisk installed

Hello friends, came out OTA update for my moto z2 Brazilian version, but I have twrp and magisk installed. Do I need to remove both and reinstall the original oreo firmware or can I upgrade normally?
ps: sorry i'm kinda noobie
EDIT: resolved: method posts below :victory:

after some internet research, i did the update as follows.
MOTO Z2 PLAY MODEL XT1710-07 (I don't know if it works on other models)
1 - be in the version "RETBR OPSS27.76-12-25-23"
2 - completely removed magisk
3 - original re-flash recovery from last rom OREO from fastboot (XT1710-07_ALBUS_RETBR_8.0.0_OPSS27.76-12-25-23_cid50 ...) to remove TWRP
4 - Download Pie rom (XT1710-07_ALBUS_RETBR_9.0_PPS29.133-30_cid50 ...)
5 - Flash from fastboot with the following commands (I did not wipe not to lose the files)
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

Right after I posted this thread I found my solution... The script I yoinked from the Android 8 ROM was missing one sparsechunk, got it working again now.
Will never do that again.

I recommend creating your own .bat file from the flash_file.xml
Use a batch file for easier flashing

IMEI missing. Revert to stock rom? Which one?

Hello,
I got an unlocked Moto G7 Play from ebay and apparently flashed LineageOS successfully. Set up all my apps etc, but when it was time to move my SIM card over, Mobile Network is grayed out, and About Phone -> IMEI said unknown.
It sounds like I need to revert to a stock rom to try to get the IMEI back, but which ROM?
This should be a US Moto G7 Play, unlocked - no carrier.
Also, once I find the right ROM how do I install it?
I am primarily a Linux user, not Windows, if that matters.
Thank you very much for any help.

Its best if you flash with windows, but it's possible with Linux too, but I had driver problems and computer wouldn't recognize phone.

Had the same problem, this worked perfectly. Some of the commands are redundant as there aren't any files with that name in the rom zip (system sparsechunk 9 to 12 for example) but just ignoring them works just fine. Thanks.
