You don't have to switch modems/bootloaders before flashing it. But You need to wipe data before as it will give You a ton of force closes.
So backup Your apps with titanium or other app and flash MIUI, then just restore those apps and You should be fine .
Also for everyone else
This rom is prerooted with SuperSu 1.79 but it won't show You any prompts. It will just grant access always.
Battery says that it's 2600mAh but it won't affect Your battery life.
This rom is based on Marshmallow. Not Nougat. So that means that xposed etc should work .
Fingerprint and everything works great. It also uses samsungs stock camera therefore it has perfect camera quality.
Source? It's a patchrom so there is no source other than the patchrom source on github. But building Your own MIUI is extremely difficult so If You want to improve this rom. Just use apktool and obviously ask the devs for permission.
Overall bugs are barely visible in daily usage. So no worries there. Feel free to flash this rom and enjoy .
