Selecline Smartphone 5 (auchan-s6s5in3g)

Also known as Maysun M5016

have in mind that it's hard to find info about this phone (also it looks like this is not the only  Selecline Smartphone 5, maybe I should use M5016 codename as official(ish) name?

Official name is Selecline Smartphone 5" but I omit the " symbol which creates more trouble than I thought in scripts

What works

 * Nothing

What does not work

 * Everything, no kernel sources available

How to enter flash mode
Probably unlocked bootloader by default, needs proper images

Probably AOSP recovery or similar

Reflashed with TWRP, unfortunately I don't have copy of original bootloader

Key combination:

`
 * Press and hold power,
 * Quickly press and hold VOL-,
 * Release both buttons as soon as boot logo shows on screen
 * You're in recovery mode now, navigate to "bootloader" (VOL+/-) and press power to enter fastboot mode.

Original software
Android 6.0 with 3.10.65 kernel, might be the most stock system I've ever saw

I've managed to flash TWRP from different phone on it, so only adb. Unfortunately that made Android to be stuck on boot logo. Adb works fine in Android and recovery, whereas in recovery the shell runs on root priviledges
