Need to qualcomm flash Gr5 Kii-l21

[Delta2010]

Good Morning Guys,

I've totally bricked my phone, nothing is working on it, Bootloader in locked, FRP is locked, flashed even VIP stock roms yet nothing changed.

Installed DC Unlocker, said that it's finished the job but still nothing happens.
So the only remaining solution for me is to OPEN UP the hardware and try to flash the QUALCOMM processor itself.

Is there any guide for that?
Also do I need a special stock rom to install to the GR5 Kii-l21?

Please help.. ty

There is no guide available for this right now..
I would suggest you to visit service center to get your device fixed.

it will cost me a lot, then they will take the easy way and tell me that they will change the motherboard

Thats exactly what they will do..but tell them to give a try to flash software first..

I can help

I have the same device, and I unlocked it and flashed custom recovery and changed to another rom, I just don't understand what's going wrong with the unlocking procedures, can you upload pictures of the phone on the bootloader and the CMD when trying to unlock the bootloader

You can still flash through Qualcomm 9008/edl mode.
You're gonna need a factory firmware (some call Board Software, Board Firmware :silly.
I also have a bricked KII-L21 devices. Everything started from flashing a wrong oeminfo image. Bootloader is relocked ( Serial number and IMEI mismatched I think). Nothing can be flashed in normal way.
I found a link to this KII-L21 Board Software but it is a paid service .

I have a GR5 KIW Board Software but it doesn't work in KII-L21 device. It doesn't boot up.

So, If you can buy/find/get a KII-L21 Board Software ( not for me ), I am willing to help you.

hey dude, i used DC Phoenix which is a paid service, and they gave me the factory firmware for KIW-L21, the only thing i need is a way to flash it
i could upload it and share it with you if it helps you solve your problem
