In this video tutorial, I'll be explaining how to flash a Qualcomm Android device using Qualcomm
Flash Image Loader or QFIL. In order to use QFIL, you need to have installed QPST.
You also need to have installed your Qualcomm USB drivers. We have a guide on how to do that
and of course you need to have the
firmware which you intend to flash usually
in this format. Now, once you have all these in place, the next
thing you'll want to do is to launch QFIL so I'll do that by searching for
QFIL. If you have a desktop
shortcut you could also launch the
shortcut and wait for the QFIL
dashboard to come up. Alright! Great! So I
have this here. Now, I have no port
available so I need to connect the device
in EDL Mode. Now, for this particular
device, to boot into EDL, I power off
the device still with battery inside, hold both volume buttons then
connect it to the PC via the USB cord. Alright! So that changes No Port Available to
Qualcomm HS-USB QDLoader. Now, the next thing you'll want to do is to
load the firmware which you intend to flash. The firmware I have here is a Flat Build
so under the Select Build Type, I select Flat Build then I click on Browse. Now, in
this Window that opens, what you'll want to do is to navigate to the location where you have the
firmware folder and then you open that
and select the loader file. its usually in
this format and then click on Open. The
next thing you'll want to do is to click on Load XML.
Still in the firmware folder, you select the raw program file and then click on Open and
then another Window will automatically open. You select the patch() file and then click on
Open. Alright! So everything we need to do is in place so the next thing you'll want to
do is (still with the phone connected) you click on Download and that
should start the flashing process. Now, to
be sure that flashing has begun ,you are
going to have a blue bar loading. That is
confirmation that we have flash in
progress okay? Great! So we have the blue bar loading right there so it's very
important you do not interrupt the process because if you interrupt the process
that is going to cause your Qualcomm Android device to get bricked and then if you
are lucky, you'll be able to revive it by
retrying to flash it using QFIL and
if you are unlucky, you have to find a
way to get the bootloader for your
particular device, flash the bootloader
first before you talk about flashing
the firmware and that could be a very
tedious process so to just avoid going
through that headache, do not
interrupt this process okay? Just sit back
and QFIL do its thing.
So I'm at 7.21%
okay 23.47% now
Okay, so we are 83.83% and flashing
should be completing any moment from
now still have to be patient , do not interrupt the process.
Okay, flashing is rounding up right now. I should get a confirmation message
anytime soon showing that flash was indeed
complete and successful
Alright! Download Succeed. I have it
right here
Finished download so you can disconnect
the device and power it up. If you get an
error message asking you to reset the
encryption data or encryption unsuccessful
just reset the phone and that should make it boot up normally. So that's how
to flash a Qualcomm Android device using Qualcomm Flash Image Loader or QFIL
