QPST(Contains QFIL)

Qualcomm Drivers(Signed)

Make sure you follow these steps exactly

This tutorial has two stages - If your phone is brand new: proceed to step - b. If you have messed up following the tutorials online, forget everything and start from step - a:

a) Flashing with Fresh Stock ROM(requires PC)

Install the drivers and QPST without any errors(Sometimes you may need to disable Driver Signature Check, Google how to do it)

Charge your device fully or atleast 75%

Extract the S045 version to the clean location. Try to keep the path as simple as possible.

Open the QFIL application

Press both Volume + and - together and connect your phone

The red LED will glow and your PC will detect the phone

On QFIL, It will show as qualcomm hs-usb qdloader 9008 <COM PORT>

Now select Flat Build radio button

Click on the browse button and select prog_emmc_firehose_8936.mbn

Click Load XML and choose rawprogram_unsparse.xml and patch0.xml files

Click Download and the flashing will begin.

Be patient, it will take upto 15 minutes

After the flashing is complete, you will see the blue text: DOWNLOAD SUCCESSFUL

Disconnect the phone from the PC

Now press the power button and wait for the phone to boot up(Be patient, first boot will take longer)

Don't insert sim / sdcard yet

Once you see welcome screen, just do basic configs and reach the home screen

This is the tricky part! Don't do any configs or settings...

At this stage, when you type ####6020#, it will show you default - This is completely normal

Now follow the procedure a) above

b) Updating the phone with OTA

You may get OTA on your phone or when turning on the brand new one

Make sure you are on stock firmware and NOT rooted

Charge your device for about 75%

Download the OTA from above links

Extract the zip for these files: India2Default.ota.zip, India.ota.zip, System.zip

First flash S056 and then S105

Switch OFF the phone and reboot into recovery(Press Vol +, Vol - and Power together)

Follow this order while flashing: India2Default.ota.zip -> System.zip -> India.ota.zip

Choose install update from sdcard and select the OTA zip & confirm.

It will take about 15-20 minutes for the each of the OTA to install

After update, phone will reboot automatically

Be very patient, first boot will take a bit longer

Congrats, your phone has been updated! Enjoy!
