How to use QFIL to flash Qualcomm (QLM) firmware

The tool can flash a firmware in Flat or Meta build. For Flat build, the firmware needs to contain:
.xml files (programmer file etc), .img files (recovery, boot, system etc ), .mbn files (tz, rpm, prog_emmc_firehose etc), .bin files (gpt, NON-HLOS etc)

If you encounter SAHARA FAIL ERROR then ensure to use a programmer that's compatible with your device

How To Flash ROM Using QFIL or QFIL Flashing Tool

00:10
In this video tutorial, I'll be explaining how to flash a Qualcomm Android device using Qualcomm

00:15
Flash Image Loader or QFIL. In order to use QFIL, you need to have installed QPST.

00:21
You also need to have installed your Qualcomm USB drivers. We have a guide on how to do that

00:26
and of course you need to have the
firmware which you intend to flash usually

00:29
in this format. Now, once you have all these in place, the next

00:32
thing you'll want to do is to launch QFIL so I'll do that by searching for

00:37
QFIL. If you have a desktop
shortcut you could also launch the

00:42
shortcut and wait for the QFIL
dashboard to come up. Alright! Great! So I

00:47
have this here. Now, I have no port
available so I need to connect the device

00:51
in EDL Mode. Now, for this particular
device, to boot into EDL, I power off

00:57
the device still with battery inside, hold both volume buttons then

01:03
connect it to the PC via the USB cord. Alright! So that changes No Port Available to

01:09
Qualcomm HS-USB QDLoader. Now, the next thing you'll want to do is to

01:14
load the firmware which you intend to flash. The firmware I have here is a Flat Build

01:18
so under the Select Build Type, I select Flat Build then I click on Browse. Now, in

01:24
this Window that opens, what you'll want to do is to navigate to the location where you have the

01:28
firmware folder and then you open that
and select the loader file. its usually in

01:34
this format and then click on Open. The
next thing you'll want to do is to click on Load XML.

01:40
Still in the firmware folder, you select the raw program file and then click on Open and

01:44
then another Window will automatically open. You select the patch() file and then click on

01:49
Open. Alright! So everything we need to do is in place so the next thing you'll want to

01:54
do is (still with the phone connected) you click on Download and that

01:59
should start the flashing process. Now, to
be sure that flashing has begun ,you are

02:04
going to have a blue bar loading. That is
confirmation that we have flash in

02:12
progress okay? Great! So we have the blue bar loading right there so it's very

02:18
important you do not interrupt the process because if you interrupt the process

02:23
that is going to cause your Qualcomm Android device to get bricked and then if you

02:28
are lucky, you'll be able to revive it by
retrying to flash it using QFIL and

02:36
if you are unlucky, you have to find a
way to get the bootloader for your

02:40
particular device, flash the bootloader
first before you talk about flashing

02:45
the firmware and that could be a very
tedious process so to just avoid going

02:50
through that headache, do not
interrupt this process okay? Just sit back

02:55
and QFIL do its thing.

03:06
So I'm at 7.21%

03:20
okay 23.47% now

03:58
Okay, so we are 83.83% and flashing
should be completing any moment from

04:09
now still have to be patient , do not interrupt the process.

04:18
Okay, flashing is rounding up right now. I should get a confirmation message

04:27
anytime soon showing that flash was indeed

04:32
complete and successful

04:40
Alright! Download Succeed. I have it
right here

04:44
Finished download so you can disconnect
the device and power it up. If you get an

04:50
error message asking you to reset the
encryption data or encryption unsuccessful

04:55
just reset the phone and that should make it boot up normally. So that's how
