[Samsung Galaxy A3, A5, A7 (2017) ROMs, Kernels, Re] corsicanu:
Disclaimer

I am not responsible for bricked devices, dead SD cards, thermonuclear war, or you getting fired because the alarm app failed. Please do some research if you have any concerns about features included in this ROM before flashing it! YOU are choosing to make these modifications, and if you point the finger at me for messing up your device, I will laugh at you.

​

Some personal thoughts:

- you should read at least install instructions stated in this post - i won`t offer support for any issues regarding installation;

- press 'Thanks' button instead of saying it - it will keep the thread clean and keep me motivated to do more;

- feel free to donate to me if you want to support my work;

- if you take any of my work without my permission i'll report you, and you'll probably get banned.

Installation steps

Proceed only if you updated Bootloader and Modem to Oreo! (info here)

Make sure you have twrp 3.x installed (download from 2nd post, install instructions here)

Make sure your phone is charged to at least 70%.

Download the ROM, and transfer to your phone / external SD card if you have encryption active

Make sure OEM Unlock is on in developer settings

Boot the phone into TWRP

Do a FULL wipe: Dalvik Cache, Cache, Data, System

- If you come from stock rom, probably encryption is active, you need to format data partition in twrp-wipe menu

Flash rom and boot (first boot may take 15-20 min)

If you face any lags/hangs at first boot, reboot 2-3 times and it will be fixed

uncheck diagnostic data in setting wizard

How about bugs?

Major issues for your info:

Selfie focus (background blur on selfie) - will be fixed later

Bixby Voice Wake-up
