What is a bootloader and how do I upgrade one?

Hi guys
I bought the Note 3, I'm trying to put TWRP recovery on. But there is a note saying
Use the 4.3 version of TWRP if you have never upgraded kitkat bootloader. Otherwise make sure you use the 4.4 version. These versions of TWRP have different DTBs and will fail to boot if you do not match your bootloader.​
So, how do I know if I have which bootloader?

Get an app from tge Play store. It's called Info. Here is the link:
https://play.google.com/store/apps/details?id=com.app.info
You will find there what you need. Good luck!

Wrong post

Can you check if I have the correct bootloader installed?
I can not make any phone calls at the moment, I get "com.android.phone as stopped" error. Is something wrong with the bootloader, or kernel or the rom or something else?
Please help me. I can not call or receive any calls, I miss talking to my mom.

You have to replay entire procedure: unlock bootloader - flash TWRP - root.
BTW after dualsim enabled you make upgrade to C432B130 firmware?

And with ARB mode active, what is the problem?

For me there is none, just wondering of it is the same on other Redmi Note 7.
ARB seems new to me, I should research more on it and how it affects ROM & kernel flashing.

I confirm: just bricked my phone.
edit: OK. Got the situation sorted with flashing through fastboot following instructions here (complete flash, link below includes links to tools and proper ROM). Need to completely flash the phone but not to lock :

A Message in chinese appears in Mi unlock

Hello all, so I've been trying to unlock my Redmi Note 7 since two weeks now, I download the unlock tool did everything, at first it didn't work on my Windows 10 machine (the tool did not detect my phone at all), so I tried it on my old Windows 7 Laptop and had the drivers installed and all is good then I boot into fast boot and press unlock. After that I get a message in chinese, which I can't read, so I asumed it said I had to wait, again that was two weeks ago, I kept using my phone regularly, and today I tried the unlock tool again and got the same result, since I can't read chinese, I don't even know where to start.

Help me root my Galaxy A20

Hello guys, I am new here.
So basically I got a new phone which is the Galaxy A20, but I would like to have full control over the phone as I did on the previous phones I had.
I tried a lot of videos from youtube and tutorials from here & Google, but failed to the end.
I was able to unlock the bootloader, which was easy. But I cannot find any TWRP based on my phone version.
