Default Problems with my Jiayu G3T

Hey guys, i have a G3T running the official ROM

Today the phone is stuck on loop, it shows the logo, then goes black, then shows the logo again then goes black etc

Ive downloaded countless versions of SP flash tool and many many scatter files, each of which are giving me errors.

Can anyone please point me in the direction of the best version of SP flash tool to use, the correct scatter files and the best recovery image

I would really appreciate

Thanks guys
