[Solved] Unbrick (Hard Bricked/Dead) Motorola G 4 plus or any Qualcomm mobile Device

[echo92]

Okay, so for those trying the new blankflash we have (https://forum.xda-developers.com/mo...icked-dead-t3585016/post73430127#post73430127 if you've not seen it already), I've uploaded the NPJS25.93-14-4, March 2017 and NPJS25.93-14-8, June 2017 GPT and bootloader files to here: https://drive.google.com/drive/folders/0B-GUyOfb8OgzcUl1NUtHYWNIR2M

You'll see 2 separate zips, each with the appropriate files for each build, extracted from their fastboot files directly. The following file sizes and checksums should match when the files are expanded (ensure you download the GPT and bootloader you want!)
March 2017 -
GPT: 32 KB, md5: be97a48f5ab36009b8c5e5bd55453f1e
bootloader: 3.56 MB, md5: 2f7a44bba145811bb6cd4267d6d19805

June 2017 -
GPT: 32 KB, md5: 88bc92ebbb172dc2c17321a4b6b10aea
bootloader md5: 3.56 MB, md5: 1e82257d86c0211283775e2572b26a2f

Use these files as in the post linked by baunthiyal https://forum.xda-developers.com/showpost.php?p=71405834&postcount=23 As lCrD512 notes in that post, be aware that you should use the latest firmware (so you may opt to use the June 2017 GPT/bootloader above).

EDIT - if you see the 'waiting for device' command whilst attempting to flash GPT and bootloader, try un-plugging and re-connecting your device to fastboot and see if it senses your device. Credit to https://forum.xda-developers.com/showpost.php?p=73433267&postcount=299

A personal request, if you do get your device working, please be really careful if you downgrade next time and try not to, or if you do downgrade, don't update via OTA? This time we were lucky...

EDIT - baunthiyal is too quick for me

why its saying waiting for device? in CMD ... while giving command "fastboot flash partition gpt.bin"

If you type 'fastboot devices' (without the quotes) in adb, does your computer see your device? It should report back your serial number if the GPT and bootloader were flashed after the blankflash and the reboot.

Thank you for posting the links in order @echo92
It will be easier for others to get the correct blankflash file.
And downgrading is something I'm not doing now, definitely. Neither is upgrading through OTA (although I really don't think we are going to receive any updates anymore)

You first have to get the blankflash to work. These commands come afterwards, once you are able to turn on your phone in bootloader (fastboot) mode. As @echo92 pointed out, your phone must be detected in fastboot after successful blankflashing.

[tawanda01]

[Ali.B]

fastboot device detected serial number? my device is waiting, what to do

Did you succeed in blankflashing? It'll only be detected after that.

P.S: I've given my phone to a local shop, will get it back and do the process.

 

[aaryan1596]

My XT1643 is successfully recovered, thank you so much for this blankflash.

If you are in bootloader, try disconnect cable and connect it again. Then fastboot devices must see you device. Maybe reinstall Motorola drivers and adb and fastboot.
