[TWRP & Custom ROM]Huawei Y6 MYA-L11

Introduction

This ROM is working for Huawei Y6 MYA-L11 I fixed the cellular network (SIM card recognition), but I don't know how to fix other issues as it won't boot up if I put some Huawei libraries.

Huawei Y6 2017 (Huawei Nova Young) doesn't have an official page, not even a custom ROM, nothing, so I needed to take action on this and free ourselves from Huawei terrible practice to lock everything.

So here it is, finally custom ROM to this shady model name and device.

[What doesn't work]

Back camera
Back flashlight
And the front camera is capturing in upside down
NFC
Easy button (won't be recognized as it's Huawei specific hardware code)
GPS is kinda shady, don't know if it works or not

[What work]

Everything else

[Unlock bootloader]

First we unlock the bootloader on huawei that ask us for the code. We need to bypass it.

d. type this command :

e. done !! your phone will report now and it will do a full factory reset and will delete every thing .. so make sure to have backups

f. and don't relock the bootloader (huawei problems), as it can brick device, live with an unlocked bootloader

[TWRP]

Flash TWRP recovery

now with an unlocked bootloader, time to flash TWRP recovery

in booted android go to developer options>enable USB debugging and also enable/check OEM unlock (so you can modify partitions)

download twrp-3.2.1-1.zip (note: older version also available: twrp_3.1.1.zip)

unzip file and flash in bootloader mode

fastboot flash recovery recovery.img

You can rename .img file as you want.

or use SPFlashTool.

Boot into TWRP recovery

To boot into recovery, first you need to completely turn off phone.

Then hold volume up + power button.

Release volume up and power button, moment when you see warning for unlocked bootloader (as if you hold longer it will bring you to huawei erecovery)

It should boot TWRP, but don't enjoy yet, when you see TWRP boot logo, tap on screen (anywhere) as much as you can (and as fast), because TWRP have some touch issues (buttons don't work, slider slides but don't react to it)

If slider and button work fine then you can proceed, you successfully flashed TWRP.

[Flashing custom ROM]

Backup

First you need to backup everything.

Go to Backup

And check all boxes (because huawei have hardware-specific code for their stock ROM and you don't want to screw up anything, or lose some important partitions)

Swipe to backup.

Save it to somewhere safe (on PC)

Preparation for flashing custom ROM

Download Huawei MYA-l11 DotOS v1.2.zip

Download gapps: https://opengapps.org/

(Download ARM64, 7.1, Pico)

Put those 2 files in SD card or internal memory.

Now boot into TWRP, and go into Wipe>Advanced Wipe

Check Data

And click button (above slider) Repair or Change File System

Click Change File System

And then choose EXT4

The reason for doing this is that Huawei f2fs is encrypted, and if you flash it without this, it will be stuck on asking you for the password, and you would have to reflash stock recovery and all can get messed up, just follow these instructions

And then, again, go to Wipe, and wipe Data, Cache, Dalvik and System (clean flash)
