Help Phone Stuck In Bootloader Screen Zte

Mar 6, 2015
I was upgrading the current Stock rom on my ZTE Nubia Z5s Mini, I went through the recovery mode to load the new rom and got a message saying that the rom installed correctly, I rebooted the device and now its stuck at the MIUI logo or if I try to load the recovery mode I get the Nubia logo just to load back to the miui logo again. I got the rom from the MIUI site its v5.

I've left the phone for over an hour hoping it was just loading up but no change, the phone heats up and even has a charger screen when plugged in.

Anyway to get back into the recovery mode to load the original rom again or any other way of fixing this? help please.
