Ok, I know what you are going to say, but I'm sorry.
So I saw that there was the MIUI 8 OTA update available tonight so I (stupidly) decided to update the phone, only now it is bricked/bootlooping and does not go past the "Mi" opening screen before restarting. (Bootloader is locked btw)
Before you ask, yes I have thoroughly checked through the thread below, but cannot get it to enter "EDL mode" using "dab reboot edl" nor by the method linked on that thread (2nd link below)

Thanks for you help in advance
EDIT: if it makes any difference to your recommendations, I have fastboot already on the phone (the bunny)
Also, when I use CMD to enter EDL, I can recognise the device attached, but when I enter "dab reboot edl" it just reboots normally and stops at the "Mi" screen as usual
Am I right to say that it goes to the "Mi" screen, then the screen blacks out and the phone hangs?
If that's the case, don't worry. I freaked out for a day before finally figuring out the solution.
Solution: After it loads the Mi screen and hangs, DO NOT TOUCH YOUR PHONE. Leave it as it is. Come back to it in 2 - 3 hours, and magically your phone will be switched on and working.
