I don't root any of my phones, downloading unofficial software is just risky business IMO, my phone began to crash and reboot so I just sold it on Ebay after no reply from Blu support regarding the issues, of course they did email me after I sold it. (a week later)
Anyways got a Nexus 5x on Project Fi and very happy now.
I have a Blu Studio One Plus.
Very fast, very beautiful and delicated. Everything is fine. The frontal camera is a little poor, but nothing that would stop me from buying the cellphone. I just got a little disappointed because it doesn't have a gyroscope, but the rest is fine. Like I said, the design is really beautiful. I just thrown mine into water yesterday, opened it and it didn't seem to suffer a bad damage too.
I got root rather easily with the "Ringoroot" app. Then, uninstalled it and installed SuperSU and BusyBox. No custom recoveries however, unless you build your own.
I need to do more research into MTK before that'll happen for me.
My phone has charging issues and now after it aid full charge it wont turn on. I have tried the volume and power and pc connection, and even vol pwr and home buttons anyone have any ides?
