My Device doesn't turn on anymore

[OkunionRingz]

I was suppose to relock my bootloader, looked on YouTube and Google for answers. And tried this set of commands in the Cmd:
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 boot boot.img
fastboot oem lock

At the commands "flash oem oem.img" down to "fastboot flash system system.img_sparsechunk.4", it says that it failed at the end. I tried three times, still the same thing, so I got desperate to fix the issue and looked on google how to relock bootloader again.

And I just found another set of commands from a website to start off the process:
fastboot oem fb_mode_set
fastboot flash partition gpt.bin
fastboot flash bootloader bootloader.img
fastboot flash logo logo.bin
fastboot flash boot boot.img
fastboot flash recovery recovery.img
fastboot flash dsp adspso.bin
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 modem NON-HLOS.bin
fastboot erase modemst1
fastboot erase modemst2
fastboot flash fsg fsg.mbn
fastboot erase cache
fastboot erase userdata
fastboot erase customize
fastboot erase clogo
fastboot oem fb_mode_clear
fastboot reboot

At the end, my phone just ends up dead, I tried turning on back to fastboot mode, it didn't worked. i tried turing it on like how we usually turn it on, same results. I tried charging the phone, the same nothingness we see when our phones are off, and I know that I charged my phone before attempting to relock bootloader.

And I think I just bricked my phone.

Edit: I'm using a Moto G5 [cedric]

Never try and relock the bootloader once you have unlocked it - there is just no point as if you don't do it right you will destroy your device & if you do lock the bootloader without flashing the firmware correctly you may never be able to flash the correct firmware or do it properly again (without specialist equipment)

The first set of instructions you did would never work as for this device there are 9 sparsechunks 0-8


The second set of instructions would not have locked your bootloader but would have just re-flashed stock firmware


The chances are you either flashed the wrong firmware or you tried to flash old firmware and corrupted your gpt & bootloader

If you can't get into your bootloader then follow my guide below step by step exactly - however you may only be only to re-flash firmware if your device is bootloader unlocked as you may get validation errors when trying to reflash gpt & bootloader
