unfortunately I can not trace the mounted sensor type, even going to the factory mode, only UMI can tell us really sensor mounts

Did you read back? Holzi sent two links with people that already discovered the sensor.

OV8858 from Omnivision on the backside and a gc2755 from I dont know.
...
Just stumbled accross a github repository with the kernel source of Elephone P6000. It contains a driver for the ov8858 camera sensor. Maybe we can compile it and run it on the Emax.

And:

Maybe someone with deeper knowledge can have a look into this repo too
Some ARM64 defconfigs for MT6752, with settings for OV8858.

unfortunately the OV8858 is mounted as a photo sensor front in many devices and not as rear

anyone knows some guide for porting rom on mt6752? unfortunately I only worked on mt6582 but it is not the same thing. as regards the cam our OmniVision is used for the front cam in many devices, someone wants to help in porting?

you can try this.

use emax 5.0 LP beta ROM and replace boot.img with the boot.img from MSTAR S700 ROM (it's on needrom). Also replace the original recovery.img with twrp-recovery 2.8.7 for lollipop. Flash this with SP Flash Tool. After that replace the modem file with the one from KitKat via TWRP file manager and root the phone with SuperSU.

MSTAR S700 has different kernel drivers and camera, so it would be useless. I tried to use our lollipop kernel with bootimg of MSTAR but will not start, also need to bring the cam libraries, not just the kernel

MSTAR has different kernel and camera driver, so it would be useless. In addition it must also bring all the cam libraries, not only the kernel.
