Note: If downloaded PORT ROM is SP flash tool flashable and not recovery flashable then extract system.img using ext2explore or dsixda's Android Kitchen.

b) open folder system in STOCK and copy folder vendor
c) open folder system in PORT and paste folder vendor

Step 10:

Open build.prop in PORT and search line ro.sf.hwrotation=

If value is 0 then change it to 180 as MMX A106, Myphone Agua Rio Lite, Wiko Bloom have flipped screen.

In build.prop search lines
