I have installed marshmallow and nougat on the blackview P2 using the SP flashtool - but I cant install twrp using the same SP flashtool .
Basically I loaded the scatter file of marshmallow, then clicked on the location of the recovery image file and replaced it with the twrp img file that I had downloaded separately.
But the alternative recovery was not flashed . twrp img was not flashed. It remained stock recovery
What am I doing wrong ?
