[Q] Do I need to upgrade bootloader before installing custom rom?

Hi there,
just got my hands on this international Note 3 and looking to root it and install a custom rom. I think I got all the information and softwares on how to root and flash custom recovery. but I'm just not sure if I need to upgrade my bootloader before flashing a custom rom? I don't even know what bootloader i'm on. but I do know that I'm still on 4.3 stock.
please let me know of anything that I need to do before flashing a custom rom.
thanks so much!

first step, flash with odin stock KK rom to have good bootloader, after root and put recovery you want and don't preoccupate anymore bootloader and flash custom rom or not...

ok thank you!
I tried using kies to upgrade to 4.4 as i figured that would be the easiest way, but keep getting an error, so I do need to flash stock using odin. but I'm so confused as to which one to download. right now when I fire up kies, it shows this:
current firmware version: PDA:MJ7 /PHONE:MJ7 /CSC:MJ6 (ZTO)
Latest firmware version: PDA:NG3 / PHONE:NG2 / CSC:NG3 (ZTO)
can someone let me know which firmware I need to download from sammobile.com?
thanks so much.

oh please disregard. I didn't know sammobile.com had a place where we can search by country, etc. it's really cool. so I found what I needed.
thank you.

I was able to do an OTA update, so now I'm on kitkat 4.4; so my question is, now do I need to do anything for preparation in order to root?
thanks.

nothing to do
flash cf auto root and you re done...

thank you! you guys are great!

Simply install any LP ROM with specified instructions. Or if you want to restore pure stock, Relock bootloader and Install the IMG file.

You can use the modded stock rom and flash it from TWRP --------> Modded Lollipop 40.60 Stock Rom (Google Drive Link)
and flash the stock kernel through fastboot before you update to build 40.87 --------> Stock Kernel (note - this will remove the TWRP recoveries, After update you can flash TWRP recoveries back)
Otherwise, you can use this tutorial If you doesn't want to download the files. ( I recommend you to just download the flashable stock rom )
Or you can download and flash any custom stock rom (I prefer cleanstock rom, not to much bloatware)
Good luck

It's simple boot into recovery and make a back up of your stock Rom in case anything goes wrong. Download any custom Rom but make sure you are on the correct modem and bootloader before installing

Is it necessary to install modem and bootloaders when installing any 6.0.1 based custom rom(Not 5.1 or LOS 14.1)?
My phone baseband is N910CXXU1DPI1.So can i flash any touchwiz rom directly?

Bootloader and modem question

How do I know which bootloader do I have? I'm currently running build B35.
Can someone direct me to a thread how to flash universal bootloader and modem?
If I use bkores flash toolkit, it said you have to flash universal bootloader, modem along with Rom and Gapps but in which order?
If using twrp for future flash do I need to flash universal bootloader and modem every time I switch ROM?

I'm not an expert but here's what I understand.
1. You don't have to worry which version you have unless you're flashing a custom ROM, usually for Nougat you want the B15 and for Oreo you want the B35.
2.Universal Bootloader>Modem>ROM>GApps>Magisk/SuperSU
3.You only need to flash it once if you're switching ROMs with the same android version.

If you haven't you need to unlock your bootloader before you can start flashing custom ROM. You can find a guide on how to do it here.

How to root and install custom roms easily?

I just bought a secondhand s10+ exynos. I wanted to root and install custom roms on it but all the solution i found is complicated. Id there any way to root this and install twrp without downloading the firmware? Thanks jn advance

I would say that you can use the TWRP guide to install the recovery and then continue to install a custom rom or using Thunderstorm Kernel if you want to use the stock rom.
You still need to unlock the bootloader but it is the only solution i know so far.
Here is the official TWRP thread: https://forum.xda-developers.com/t/...-0-x-twrp-for-galaxy-s10-e-5g-exynos.4180287/
