Root or permissive mode on Mediatek MTK6572 running Android 5.1 stock?

[gnidorah]

Hello.

I have a device:
- MTK6572
- stock Android 5.1
- 3.10.something kernel
- no boot lock, flashing with sp flash tool, images must correspond so called scatter on the phone; or possibly via adb flash

Issues so far:
- no known rooting method, most of tools for mediatek including recovery automakers are obsoleted
- no source codes from vendor
- getenforce returns Enforcing
- adb boot returns unknown command
- normal boot restores stock recovery from /system/recovery-from-boot.p, but that's not critical

The only thing I was able to achieve is to get root shell by replacing adbd with permissive adbd in boot.img, but that not much go due to selinux restrictions.
What would be potential escape from prison plan? There are many info, but none of them seems to fit.
I've heard of success with Android 6 and SuperSU, but what be the exact precise instructions on how should I modify stock boot.img and probably recovery.img to get root?

Thanks.
