[Android Q&A, Help & Troubleshooting] Izaiah Coronado:
so i have a LG K20 (mp260) from MetroPCS, and like a fool, i flashed a rom that wasnt compatible...

its now hard bricked. my computer can only recognize it now as "Qualcomm HS-USB QDLoader 9008 (COM3)" in the "Ports" section of the device manager. the device itself cant turn on for nothing, there are no lights, no vibrations. but my computer can read it...

i have minimal knowledge on this stuff and ive been at this for almost a week now and how found nothing but the QFIL program that looked promising. ive installed all the appropriate drivers and give it the appropriate files (i hope):

Programmer: prog_emmc_firehose_8936.mbn

XML: rawprogram0.xml with the patch: patch0.xml

the files were manually extracted from my own phones stock .KDZ

i have seen others use rawprogram files such as "rawprogram_unsparse_without_qcn", and "rawprogram_unsparse". i dont know how to obtain these files and if they would help my problem.

(note: im using QFIL 2.0.1.7 and ive tried numerous previous versions:crying:)

apon pressing the "download" button, it says:

im getting tired of seeing this log lol. but as you can see the problem (from i can see) is that its getting stuck at the "Sahara" bit. i cant seem to fix this to save my life. and ive littrally tried everything!

yes including putting the firmware files into the "bin" folder of the program and stuff like that...

fastbooting wont work either as the screen is always black and the computer never sees it as a device, but a port.

i turned to creating this post as a last resort, for if i cant find an answer here, im afraid ill just have to use the phone for parts or something:crying:. please! if anyone has suggestion or a solution that i haven't tried yet it would be truly appreciated!
