After showing N/A didn't the device boot in to system?
If not .. than you have to flash the whole firmware again.

Use official Motorola instructions here: https://motorola-global-portal.custhelp.com/app/standalone/bootloader/recovery-images
Or the instructions here under the "Unbricking / Stock" section: https://forum.xda-developers.com/moto-z-play/how-to/howto-moto-z-play-unlock-root-t3508547

Yes. You need to install a custom boot logo with the following command:
Code:
fastboot flash logo <FILE>.bin
You can get boot logos for our device here:

Thank you. I have 2 question, if you could answer these that would be of great help.
1) is there any way to bring the phone back in warranty?
2) I installed the russian firmware and if i wish to install Indian firmware, any idea where can i get it? i searched almost everywhere but couldnt find it.
version is npn25.137-15-2

First of all, this thread is in the wrong section. This section is for development only, and you're not developing anything here. Move this thread to the General Q&A section.
Second, you didn't read the post I linked. The second link has 2 links for repositories with many factory images. Since I'm in a good mood, here's one with many choices for you: https://mirrors.lolinet.com/firmware/moto/addison/official/

Well there's no MM based SPFT file, so all you have to do is either flash stock kk/LP using SPFT or if you've twrp installed, boot into TWRP again and wipe everything except SD, flash the MOB31E full stock Rom zip. Link : MOB31E OTA's and flashable zips thread

Hello, please help
The device is canvas a1 and it is fully updated till the last update via OTAs only. I performed factory reset on it. It is now stuck on setup wizard. Not able to skip from there.
I wanted to flash it again.
So, can you please tell if it is OK to flash KK or LP flash files?
(I am asking this because, its BL might have got upgraded in OTA updates and it could be dangerous to downgrade to lower versions by flashing.)

Remove your battery and insert it again, put the device into bootloader mode and unlock it, then you can fastboot the twrp and good to go.

Nothing to worry. Once you get twrp, just clean flash stock lollipop Rom. Don't use SPFT, you gonna brick your phone if something goes wrong wrong. I'll link you LP (flashable via twrp) Rom, tell me when you done.

Hi there
I have the same problem and my phone is stuck at the boot screen.
My phone does not allow me to enable USB debugging and I am really stuck with being able to install TWRP and flash the stock ROM.
I'm incredibly confused and am unsure what I am doing. Attached is a screenshot of the CMD box.
Help and simple instructions would be appreciated.
Thanks in advance.

Help I bricked my Moto Z play

I flashed the wrong bootloader so fastboot does not work. I still have TWRP Working but anything I flash does not boot. I am looking for a full factory OTA that I can flash via TWRP so it will re-flash the proper bootloader and all the other factory images so I can un-brick it through fastboot. I have tried to flash many different update files but it gives an error 7 and says to be on 6.0.1 or 7.0 before installing it. Can someone please help me un-brick this or link a full OTA that I can flash via TWRP. I attached the bootloader.img so if anyone could make a flashable zip to flash the stock bootloader that would probably work.

If fastboot works then you're not hard bricked, most likes soft brick. I would suggest flashing magisks 14 after you flash the rom as dm-verity will check if your system is modified , dm-verity needs to be disabled

I already tried flashing magisk. Also I can boot into the bootloader but the computer does not see it in fastboot anymore (probably because I flashed the bootloader.img for the moto z play droid accidentally)

not exactly because twrp works. If I could flash fastboot images through TWRP I could un-brick it. If somebody could modify the stock rom's updater-script and remove the requirement to be running a stock rom then I could flash that and I would probably be unbricked.

Bootloader can not be flashed through twrp so you'll need to flash the bootloader through fastboot. If your device is not recognized when you plug it in your computer then you're hard bricked, if fastboot is not accessable then you're hard bricked

so you are sure that it is impossible to make a flashable zip of bootloader. Maybe it is just my computer I'll try booting of linux on usb and then see if fastboot can see it.

Do you have the correct driver,, if you use Linux there is no need for the driver just install minimal ADB and fastboot

Have you tried using these albus (Z2 Play) blank flashes as mentioned here to repair your bootloader? https://forum.xda-developers.com/showpost.php?p=73402033&postcount=181
https://forum.xda-developers.com/showpost.php?p=73411048&postcount=206
These may hopefully get your device to the point where it's recognised in fastboot and you can then flash the stock ROM via fastboot.

Moto g6 forge (XT1922-9) bricked

okay so i am pretty new still to flashing firmwares and using fastboot in general. I have the cricket version of the moto g6 play (forge) and noticed that i could not unlock the bootloader through moto's website . i noticed that the model number for the cricket version of the xt1922-9 was the same as the retail version from motorola . which on the website says has the ability to unlock . so i tried to flash the stock retail firmware for the retail and the most update verision being android pie XT1922-9_JETER_RETUS_9.0_PPPS29.118-68-3_cid50_subsidy-DEFAULT_regulatory-DEFAULT_CFC.xml.zip and ended up flashing everything succesfully other than the boot.img and all of the system.img files and when i try and reboot the phone to recovery it says failed to pass validation back to fastboot . and the baseband section in fastboot now says not found . can someone help me with how i can flash all the correct files so i can get the phone just to boot up again.
You flashed everything except the boot.img and the system.img files?? That means you mixed up two FWs on one device...
Try flashing this FW for jeter_cricket from mirrors.lolinet.com

Sorry it takes me so long to reply . Most of my tinkering time is eaten up with my other phone I have that just so happens to be the only model variant that can't unlock its boot loader hence no root or twrp ... :/
But anyway yeah I'm gonna try the tool and paste those lines of fast boot code for you. One sec.

Hi
I was messing around with my system and tought I delete everything in TWRP. :crying:
I am still able to go in TWRP and Fastboot.

Thanks a lot for your answers.

How did you root your phone? Rooting the phone is as simple as flashing patched init_boot.img via fastboot flash init_boot. A lot of users here brick their phones because they patched and flashed the boot.img instead of the init_boot.img.

He used miflash, QFIL (with various different parameters than normal use), QFL, and fastboot. Finally he recreated two super partitions for my phone and flash odm, system, and vendor images into the supper partitions. After 4 hr of trying, my phone boots however I still have the red warning "Your phone is corrupt".

Put the rom in the root directory or on external SD card through the C connector. Use local update and choose the rom.
