InnJoo ONE 3G HD 5.1 (Lollipop) root/custom recovery

I had rooted my InnJoo ONE 3G HD device running 4.4 (KitKat) using KingoRoot android app.

A few days ago I updated my device to official 5.1 (Lollipop) ROM.
After that I tried rooting using KingoRoot android app, but it doesn't work anymore.

I understand that with 5.0/5.1 (Lollipop) Google introduced an extra layer of security that essentially disallows all exploit based rooting methods.
The only way around, so far has been modding the kernel or using a custom recovery.

I can't seem to find any custom recovery for InnJoo ONE 3G HD 5.1 (Lollipop).
Also, there are no modded kernels for InnJoo ONE 3G HD at all.

I was wondering if pushing any custom recovery with MTK Droid Tool would work or not.
The only problem I see is losing IMEI info.

So, the question is, does anyone know about a method for rooting InnJoo ONE 3G HD 5.1 (Lollipop).
Or, does anyone have a custom recovery for InnJoo ONE 3G HD 5.1 (Lollipop).

Hope all InnJoo ONE fans find a solution for this soon :)
