Let's tell my experience.
I had my Moto G6 Play for near two months. I've unlocked the Bootloader and attempted to root it but unsuccessful. So, I've rolled back to my stock rom via Fastboot (using the stock ROM linked in this forum). It worked fine after that.
Some days ago, the official Android Pie update has been available, so, I installed it via OTA. However, it failed. After trying installing again, the phone gone down and never powered on again (even entering the Recovery mode, even charging all the night).
Therefore, I left the device to the technical service, knowing the bootloader unlock voids the warranty.
Does this happened to someone else? In what scenarios?
Thanks for commenting.

1. Unlocking your bootloader does not void your warranty.
2. That's a recovery loop. It doesn't look like it, but it is.
3. How to fix that crap. -Flash stock firmware, wipe data, cache, and DDR through fastboot, then issue the command fastboot reboot. Let it encrypt, then you can boot into recovery normally. If you don't let it encrypt right after flashing stock firmware then you'll loop again.

1.- Maybe, depending the country. So, the agent who attended me told me the warranty is void just when unlocking the Bootloader. Motorola's technical service will give the last word about that, as I have re-installed the stock rom.
2.- As I told, the phone don't seems to power on and no charging light. I've connected to the computer and it never identifies as anything than a brick.
3.- Per above, Fastboot won't recognize the device and unable to send commands to the device in any way. In other words, the device seems to be completely dead.
The vendor where I purchased the device just told me they will replace the device under the warranty.
So, I'll apply the updates via OTA and tell you the results, but I'll not unlock the bootloader, but backup upload the ROM via Fastboot and TWRP, and upload it.
I've finally gone to the vendor to retire the replacement device.
However, they don't have the Moto G6 Play available anymore. Instead, they gave me the Moto G6 (better device except for the battery) for free, as the failure has been covered under the warranty.
Advices:
Ask your vendor the repair costs for failures caused by failed firmware updates. I assume Motorola didn't checked even if the bootloader is unlocked (as the device seems to be completely dead), they just decided to replace the device.
Don't send the device to the technical service if it powers on and Fastboot is working unless you're prepared to pay the repairs.
Don't try to install the Android Pie update with the bootloader unlocked and firmware altered.
acutally, updating with unlocked bootloader causes nothing. that might have been a hardware problem of some source, idk...

but unlocking the bootloader does void your warranty tho
Indeed the warranty is void after unlocking the bootloader, but Motorola haven't noticed (and even checked it) as the device completely died.
¿So, where is actually stored the Bootloader? In the Flash or a separated ROM chip. As a previous flashing attempt may caused failed write to key partitions.

Not true. My bootloader is unlocked, and Motorola is well aware of that since I had to ask them for the key. Unlocking it by itself doesn't void it. It's what you do afterwards that might void it. Like running an over volted kernel and frying something. Check the screen shot. My warranty is still good until Aug of this year. And if I really wanted to I could just relock the bootloader before sending it in, which blows that theory out of the water.
i replaced one under warranty with no issue. with an unlocked boot loader. twice.
Please i need advice, my imei is missing after i flash my phone to china rom because after i upgrade it to oreo it become stuck in recovery mode. I've tried many ways to restore QCN but it need a rooted phone. Any advice please..
Since you don't have a unlocked bootloader you can't do anything, I think it's best to send it to warranty.
I unlocked bootloader of my phone, flashed TWRP and tried to bootloader lock. i cann't get boot or recovery mode, the only thing I get on my screen is ("the current image(boot/recovery) have been destroyed and cannot boot. Please flash the carrect image or contact customer service to fix it"). But there is no customer service center in bangladesh. what can i do? please help me:angel:
Hi everyone!
I received my tablet with a Chinese version. I tried flashing a global version, but I didn't pay attention and ended up blocking the bootloader. Now it gets the message: "
MiUI version can't be installed on this device" and I can't unlock bootloader to go back to the Chinese rom. Does anyone know how I can proceed?
its bricked forever?
I think not but the only way to flash a rom with locked bootloader is to use edl mode.

This guide will have an in-depth look at the EDL Mode on Qualcomm devices and its associated importance. Android devices are always known to be at the

It is very difficult procedure so read a lot who to do it corrently. Good luck!
A month ago I bricked my G40 fusion. It was in "flashing locked" state which meant I could not send any commands over fastboot.
EDL mode was of no use as there were no QFIL files available for the phone.
I paid a tech to bring my phone back to life but I do not know everything he did. I am posting what I know about the process. I understand that repair techs are dependent on income from these situations so understand that I am only posting about the limited things I know.
Process-
Phone was kept in fastboot mode(flashing locked)
MotoflashPro was used to gain information on device status.
Accessed MotounlockGsm.com through CMD(BAT file) and used usb over server to connect phone to it.
Thingamajingy happened and phone now entered "oem_locked" state.
used motoflashpro tool to flash stock rom
booted to recovery
hard reset phone
reboot.
Phone now works like before. No bootloader unlocked warnings on startup. Tech said custom roms should no longer be flashed and phone needs to be used as it is now.
My phone is Indian variant but Indian rom failed to flash. Global retail rom was flashed and works just fine.
