A custom rom never contains a modem or bootloader. So no that does not apply.
It mean no any problems after flashing?
Some custom ROMs require an up-to-date modem and bootloader. If you flash a custom ROM, the imei may disappear or wifi/calls may not work if the ROM is too new for the phone's bootloader and modem.
Before installing a custom ROM on a phone, I make sure that the phone is working properly with the latest stock ROM.

He means it the other way around. He wants to use a kitkat rom on a lollipop bootloader and modem. That's shouldn't be a problem.
I see the OP asking 2 questions:
1) Can a KK ROM be flashed to a phone running an LP bootloader and modem. Generally, I would say yes but whether all functions work will depend on the KK ROM. Some custom KK ROMs I ran on my Nexus 5 required me to downgrade the bootloader and radio to KK versions.
2) Can a KK modem and bootloader be flashed over an existing LP modem and bootloader? I think it depends on the phone's installed bootloader.
Yes audit13 brother my quistion is no1. I have now albe95 astra v2 on UHOJ2 base modem and bl lollipop. And goes to goldfinger kk base.now confused what can I do?
Did not try on i9505 but it works on i9500. I think it will work but u should backup your EFS partition
I say try the KK ROM on the LP bootloader and modem. If it doesn't work, you'll either have to find another ROM or you'll have to try and flash a KK bootloader and modem over a LP bootloader and modem.

Well, since this is noob-friendly, would I be able to install a Custom ROM IF there were one available for 4.4.2? I got a Custom Recovery from Autorec and it said it downgraded my Bootloader so that it can install and old version of TWRP.

you can install any rom for your device as long as you meet the following-
a)if you are flashing a kk rom(g pro 2/flex kk/stock kk) then you just just have to either be on kk with recovery or flash the kk baseband for your device
b)if on kk and you want to flash jb rom(stock jb/flex jb) you need to flash the jb baseband at the same time as you flash the rom
c)if you want to flash an aosp rom you either check if it supports stock kk/if it doesn't mention anything flash a kk ported baseband for aosp kk or flash a jb baseband while flashing aosp rom

Yeah, it works! Thanks for verifying for me!
hi guys, i have flashed android 5.0 stock with odin to my n9005 and then got recovery mode on my phone TWRP and flashed a couple of android 5.0 roms.. now im wondering if im able to go to kitkat (x-note) rom without any problems... my phone bootloader modem n stufs etcs are in lollipop's now as i used odin to upgrade it last time.
Yes you can go back to kitkat just flash kitkat firmware with odin and that's all
Flashing a custom ROM should not touch your installed bootloader or modem.
Try flashing a custom ROM with your existing bootloader and modem. If it doesn't work properly, then consider changing the bootloader and modem.
Hi, I have recently rooted and bootloader unlocked a G900V and it works fine on Lollipop roms, but when the device is flashed with a MM rom via TWRP or Flashfire the Wifi wont work. IDK what is up with this. Maybe it has something to do with the baseband or whatnot, I'm out of ideas so I have to bug you guys for help, thanks in advance!
A little more Info I'm on PF4 baseband. Tried the Note5 port rom, the BS free rom and a deodexed debloated MM rom and all have no wifi. Ive tried the phoenix kernel, still no go. Tried flashing the PD1 baseband as its another MM baseband and it didnt take (via odin or TWRP ¯\_(ツ)_/¯) . So idk why flashing basebands doesn't work, maybe it'd solve my problem.
By using Getex's [GUIDE] Unlocking the Galaxys S5 Bootloader using DEV Bootloader [KK-MM]
and following the bottom subsection (If You Already Have Bootloader Unlocked And On A Samsung TW Rom) I was able to fix the problem.
Nice! Thanks GETEX!
So I'm flashing stock 5.0.1. After that CF Autoroot, TWRP etc. etc....
As I'd like to flash resurrection remix 5.8.0, the thread says this:
ROM Firmware Required: Lollipop supporting bootloader and modem / non-hlos
Now the stock rom says I'm on XXUHPK2 modem and bootloader, but It doesnt say if Its combined ora just non-hlos or gsm.
What are the modem differences? Shoueld I flash another modem or bootloader?
I just understood that non hlos is for lte... but dunno whats better for the RR rom.
I'm on GT-i9505
Thanx for help
As long as the phone is running the latest stock 5.01 ROM, the bootloader and modem should be fine to use with the custom ROM.
Stock ROM flashes everything you need.
I don't want to repeat the steps from the beginning and i want to flash a kitkat rom and keep the MM modem nd bootloader !! can I? (the KK rom work using the mm stuff but navigation hardware key don'!)
Thanks
It's always advised to use the original things. Even if a KK ROM works fine with MM stuff (I think it won't), it's better to just flash a completely stock firmware through Odin and work from there.Why do you want to keep the MM modem and bootloader though? Just curious.
swear that it works tried with kk aosp roms ..
well flashing through Odin will makes my bootloader locked again(I'm g900v Verizon user)
haha nothing genius I'm just lazy to flash things from beginning and maybe there will be an upcoming interesting ROM that work only with MM BL and Modem.
Thank for the answer.
