Unbrick a Mya-L23 Huawei.

Hi recently I got my hands on a Mya-L23 and I thought it would be very good to use as a In Car Waze, so since I use a tasker app for this I needed root, so I did a booboo, rooted it wrong and ended up with a VERY nasty bootloop ( I even did open it to remove the batter ) , however I was able to recover it and see that it was almost unbrickable.

The Chip inside a Huawei Y5 2017 is basically a MT6737T so thankfully there's a tool we can use to write directly to the chip ! ( YAY ) it's called Smart Phone Flash Tool ( SP tool ) , so basically we are going to overwrite the whole phone so we have a new and fresh install.

you are going to need:

you can look for other roms here:

The ROMS ARE HUGE !!!!!!!!!

- How to do it.

1- Install the MT drivers

2- Open the rom ( unzip it )

3- locate the "download agent file" ( this is a file that will tell SPtool what will be downloaded )

in the rom I used it was called: DA_SWSEC.bin and it was located in a folder called download agent

4-locate the scatter loading file ( inside the firmware folder of the rom ) , this is a text file in my case it was: MT6737T_Android_scatter.txt

5- Now open the SP flash tool

6- Press the download tab

it will have a screen with 3 things you can write, go to where it says: "Download agent" click on choose , and add the the download agent file you identified before

7-Load the scatter loading file, pressing on choose on the second choose button, if everything is ok it will read a lot of files, and will take like 10 minutes or so... be patient

8-you will see below this a select list that says:

Download Only, Firmware upgrade, format all + download

for now select: Download only, if it fails, try Firmware upgrade, if that fails, then Format all + download

8-WITHOUT THE PHONE CONNECTED TO THE PC PRESS the Green Download button on SP tool

9-Hold the VOL DOWN button on your phone ( even if it is on a boot loop )

10-Insert a USB cable from the PC to the phone, keep the VOL DOWN BUTTON PRESSED until it starts showing a yellow like , then the rom will be written to your phone. ( after this most likely it will be alive again )

11- Profit !

---------------------- Do all of this at your own risk ----------------------

Most likely this will work with other y5 or even other phone models with the right rom and download agent...

Have a nice day !
