[Q] Rom flashing dilemma! - Galaxy Note 3 Q&A, Help & Troubleshooting

Hey guys, I'd like to know whether I can flash a rom with an older baseband version! Like if we talk about note 3 Exonus version, and I'm updated to Kitkat! My version is N900XXUDNA6 so if a rom is based on N900XXUCMK2, can I flash it!

No bootloader downgrade is possible. Once upgraded you must stay with it

I'm not sure about the exynos model but on N900W8, you can flash an older baseband through odin.

[Q] Difference between "Baseband Version" and "Build Number"

I have Froyo (motafoca's custom rom) installed on Galaxy 3 (I5801).
In Settings > About Phone following information is shown:
Baseband version: I5800xxJP4
Build Noumber: FROYO.XXJPF
What is the difference between both of these things?
Can Baseband Version be upgraded?
Baseband version means Radio version in the phone

So is it possible to update it?
When we update the ROM, or when we install a custom ROM, does this baseband version get updated?
baseband should updated if you will flash image in PHONE part in odin. if you are flashing custom rom then you do not flash this part. you flash PDA only. so radio and bootloader you usually dont flash.
flashing radio is allegedly only thing that can brick your phone.
in our galaxy 3 jpf rom we have baseband version I5800XXJP4. i think this is newest version. if not, somebody can correct me.

Its the bootloader that can brick your phone. Not the radio.

But the changes in baseband version would improve/decrease radio preformance? what will happen if you replace new baseband version with an old one?

I think as long as the ROMs you flashed is meant for the international version of S4, it should not be a problem.

[Q] Old Bootloader

Sorry if this is a noob question but will running an old bootloader (say 4.4.2 NA6) with a newer official rom (like 4.4.2 NE4) allow me to downgrade using Mobile Odin Pro?
And if thats the case, are there likely to be any performance issues with running an old bootloader with a new firmware?
KitKat boatloader works on all KitKat roms. Is good to update to latest boatloader to match the rom but no biggie if not.

so then will i be able to downgrade from newer roms to older roms with mobile odin (seeing as it doesnt touch the bootloader) if i have the oldest KitKat bootloader installed?
you can move to all 4.4.2 rom you want but NO downgrade to 4.3 rom
I'm on NA6 BL with NG1 rom

Updating to a newer ROM version.

Hello guys, I've been wondering that is it safe updating my Note 4 which is currently flashed with SimplRom 5.0.1 to the newer SimplRom 5.1.1 version without wiping out my phone? I've already google about this topic but it came out multiple answers so I thought I'll a clearly answer here.
Thanks
Yeah you can do. Just flash the 5.1.1 bootloader and modem beforehand. If you have the N910F then the latest bootloader and modem is POK1
