MIUI rom fail?

After installing I've been stuck at the MIUI_US united World wide splash screen for the past 20minutes.
Sounds like a bootloop. Did you wipe data/factory reset, wipe cache, wipe dalvik, fix permissions and (if you flashed another kernel) flash the kernel cleaning script first?
If not, do all that stuff. I flashed MIUI yesterday without issues.
if you can load into CWR goto Mounts Menu Format Data, Datadata, System, Cache, the goto advanced Wipe Dalvik. Now install Miui. and Fix permissions then reboot.
if not revert to stock via odin/heim and follow the steps above after flashing CWR.

TWRP reboots and doesn't let me wipe

So I'm trying to clean flash a ROM and I want to wipe Cache, Dalvik, System and Data, but TWRP reboots every time and doesn't finish the wipe. And nothing gets wiped.
I tried only a cache + dalvik, but nada. Instant reboot to my home screen.
Tried TWRP 3.0.2.1 and 3.1.0.0 both, same issue.
Ideas?
Solved it. Went back to the May update via fastboot & rerooted + TWRP (latest). Done and dusted.
Mods may close this thread.
Same problem here. Any solution aside from flashing factory image?
