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?

[QUOTE So, how do I know if I have which bootloader?[/QUOTE]
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.

Problem with changed IMEI Samsung A20e (SM-A202F/DS)

Hello, I'm new here so please go easy on me
My Samsung A20e (SM-A202F/DS) has got stolen while ago. The cops found the phone in a neighbouring country but it was already tinkered with. After it was returned to me, it had a problem booting. I can't remember the exact error, but I managed to fix the issue by re-flashing the firmware with Odin. Problem is, the phone does not register with my network provider anymore - in other words my SIM card doesn't work with it, I get no telephony or mobile data. After further investigation I discovered that the IMEI of the phone appears to be changed - the ones reported by the About menu does not match the ones printed on the back of the phone itself. Can this be the cause of the problem? Can someone please help?

i even tried using erecovery and hisuite but no luck whasoever, erecovery says "package info error" and hisuite says i'm on the latest version (i'm not, i'm using an emui 8 rom for ARGC771 model that isn't working well with mine, i'm looking for the one from the C771 model), not to mention that the firmware finder app is completely useless now
i had recovered my phone back to normal after unlocking its bootloader and flashing a custom rom into it, but that was like 2 or 3 years ago, but now idk where to find the firmwares i need, i'm doomed...
i need a way to return my phone back to normal... i appreciate if you guys can help me, thank you
here are my phone's exact model:
FIG-LX3 C771
Vendor: entel_cl
