You have to unlock bootloader first in order to gain root access.You can relock bootloader and regain warranty after flashing ZUI 1.9.004.But don't relock bootloader on custom roms as it can result in brick.

Just a few doubts regarding Bootloader and rooting

Hey guys, I'm new to the Redmi forums, I've been on XDA since 2012 and have been using mainly Xperia devices.
So just had a few doubts regarding this phone(bought it last week)
I read about the procedure to unlock the bootloader and everything.
1. I know unlocking will void my warranty, but can i then relfash stock rom and relock bootloader to show that the bootloader was never unlocked? We could do that in Xperia.
Is it possible to do it now?
2. Will just rooting require the bootloader to be unlocked? And if yes would the warranty be void if I unlocked the bootloader and just root the phone without flashing custom ROMs?
Unlocking bootlader procedure doesn"t void you warranty. At least in Poland
Rooting requires unlocked bootloader. Im not sure about rooting, but you can always flash offcial miui build and its going to unroot your Redmi and relock you bootloader

Install custom ROM or root with out unlock bootloader

Hi my Sony Xperia xa2 say bootloader unlock no is there anyway to force software or at least root with out unlock bootloader thanks
This is not possible. In order to flash anything to the device, the bootloader must be unlocked. The whole point of the bootloader lock is to prevent flashing anything; firmware is updated via OTA.
