Can I make a Full Backup of the ROM I currently have?

[Diogof786]

Good morning everyone, I'm new here. I wanted to try the MIUI12.5 ROM on my MI 8 Lite but I'm afraid of some problem.
Is there a way I can backup the ROM I currently have with all the data exactly the same? Similar to what happens with the iPhone.

You can create an nandroid backup using twrp. Remember to delete the folder /data/extm to avoid error 255.

I've been researching a bit and tried to use it, I ended up realizing that it is necessary for the mobile phone to have ROOT. What is the best way to do this? Is kingroot viable?

There is no need to be rooted if you use TWRP for backup. For other methods like swiftbackup etc you will have to root.
I have done several backup for different phones without root.

So I'm doing something wrong.
As you can see in the print, when I try to do the backup it tells me that I need root.

You are using the TWRP app (in Android), I believe the suggestions were about the TWRP bootloader.

Don't use the twrp official app. Unlock your bootloader first. Boot to twrp. img and backup your data. Use ADB command or Fastboot/adb tools to do it.

However, when you unlock bootloader you probably will lose your data. So back up your data like videos or music files to PC first.
