My android phone internal memory need to format. How can i do it

[anbalagan JC STUDIO]

my coolpad phone with snapdragan processor is rooted. when I upgrade it to MIUI 8 BETA ROM to MIUI 8 STABLE ROM the phone goes to black screen. after several methods i am unable to give life to it. I format the internal memory to FAT 32 file system. is it correct? if not what is the format type of the internal memory and how to format it?

Welcome to the forums. Did you reinstall Android? If you did, you shouldn't have to reformat anything.

Reflash the 8 Stable and you'll get the screen back (but not any of your data - if you don't have it backed up, and can't get it off with adb, it's gone).
