QFIL is an application used by firmware engineering to flash stock or custom ROMs on devices having Qualcomm chipsets only. This post will explain how to load Qualcomm based stock software (.mbn) on a QFIL loader tool and flash a Qualcomm smartphone or tablet in just a few easy steps.
This process can come with some complications, therefore I advise you follow all instructions carefully. Also note that I will not be responsible for any damage that may occur during this process.
How to install and RUN QFIL on PC
To begin you have to download and RUN QFIL on your PC. The application is portable therefore you don’t need to install. Simply download and extract, then launch the QFIL.exe and you are set.
QFIL is found in QPST v2.7.416 and above installer package. So after installing QPST on your PC you will have QFIL.
Download QPST 2.27.420 from – HERE
Extract an install it.
I also advice you observe and use the LOG BOX, QFIL has a log box which helps users troubleshoot QFIL errors using codes which will be displayed on the application
