Hi i'm new to the xiaomi world, i had a nexus 5 with custom roms and kernels so i know a bit about this topic. I just bought a redmi 4 3gb from ******* (i hope is ok to write the shop name), i chose the version with "custom rom" over the "global official rom" because it has italian "my language" but no ota updates, i really dont know which was better to choose, did i choose wrong? Anyway now i want to know the steps to install the xiaomi.eu rom and which rom to flash. I read a post where a guy bricked his redmi 4 and i would like to know for sure what i'm doing. Will the bootloader be already unlocked? Will it already have a custom recovery? The way to unclok the bootloader it's very strange with xiaomi.Will change rom invalidate my warranty? Sorry for the many questions and thank you in advance.
