Flashing MIUI rom (stuck at boot) - Xiaomi Redmi Note 3 Questions & Answers

So i am on Aex rom .
Now i am trying to flash hydrogen port miui10 or the epic rom port.
i have unofficially unlocked the bootloader so i am using Safe Twrpv2.
Now the rom boots but it is stuck at bootlogo even after 30 min.
i have tried everything from flashing the univeral_boot to flashing lazy flash but the problem persists.
what actually happens is that after several minutes the phone starts to vibrates in gap of sometime with screen going bright and dim.
I desperately want to flash miui rom throught recovery.
Has anyone else faced this issue.
What could be the possible reasons and how to solve this????

If u r unofficially unlocked then be careful . dont flash any firmware zip. It may relock ur bootloader.
Use latesttwrp 3.2.3 official.
Atleast once Format data(not wipe data) to decrypt ur data and internal sd..
On what miui rom u unlocked ur phone?

i unlocked it way back so i dont actually remember but it was miui6 i guess and after that i have flashed firmwares with no issue !!!
But now i want to hydrogen ported miui10 or any other miui10 ported rom.
https://forum.xda-developers.com/redmi-note-3/how-to/guide-redmi-note-3-available-twrps-t3406708
i used this thread as a reference to flash miui rom.
It tells to use Safe_Twrp v2 to avoid bootloop.
i usually use redwolf but for miui i am using this safe twrp.
So yeah this works there is no bootloop but at the same the rom is not booting it is stuck on boot animation.
so what actually should be kept in mind while flashing miui port on an unofficailly unlocked deviced
Can u tell me way to solve this??? Should i use different recovery??
i really want to try out miui10 port
It would be great if u can help me out!!!

Never tried hydrogen miui ported rom. They cause issues.
Flash latest twrp.
Before flashing rom Format data . not wipe data.

why do we need to format data???? whats the reason?????
I have flashed a lot of rom but i have always wiped data !!
Also miui thread dont mention the need of formating the data!!
Does miui ported rom require us to format data????

First thing is u unlocked ur phone on old miui6 rom. May be Lollipop miui rom. That means ur bootloader partition is outdated.
Most recent custom roms need latest miui bootloader to boot roms.
U cant upgrade ur boot loader using firmware zip with emmc appboot file. Which will relock ur phone and will bootlooop coz U unlocked ur phone unofficially .
Only offiicial unlock can update bootloader.
Now u may have tried lazy flasher or whatever patch in past. So u can try those patch to boot into miui ported roms.
I never tried hydrogen ported roms. Coz i heard lot of negative feedbacks from users who came from hydrogen roms. So i never attempted to try.
After u came from global miui u must format data. Coz miui encrypt ur phone data and internal sd by default.
If u never used format data command in past then u should do atleast once.
Encrypted data and internal sd are common
Cause which stops ur custom roms booting.

Its aex nougat Nov 13 2018 build. With stock kernel (heard that nougat gives best battery backup)
It gave 4.5 hours sot initially with negligible standby drain but now standby drain has increased

Flash this recent kenzo firmware zip. It doesn't have emmc file. It is safe. It wont relock.
