you software was the only way my Blu Diamond M D210U (android 6 marshmallow) got the custom recovery and then managed to Root it
I tried Kingo Root, and all imaginable APks for rooting
MTkRoot, MTK Doid Tools, and all other tools and sideloading
every 1 Click Rooter or custom recovery/patch or port of CWM and TWRP
even tried manual porting TWRP and failed miserably
until I found your app guys
thanks for all the hard work blood and swet
it all paid off
THANK YOUUUU!!
