[Q] What modem to use?

Hello Guys,
I live in the Netherlands and I bought a new S4 so I flashed Omega rom on it (stock version) but before I did i made sure I wrote down the baseband version I had: UAME2
Is it safe to just flash the modem back? and i'm using 3minit frame work will it be affected by it?
Any help appreciated
If the current modem can't achieve good signal strength than the UAME2 modem then revert back

I'm from Holland too and you should be fine with the modem you have. There is no need to change it as long as you have good reception and so on everywhere. 3minit framework won't affect your modem in any way. Also the only way we can flash a modem is using Odin.

Do i need flash bootloader too ? I have flashed CWM on Original Android 4.2.2 then updated to This ROM
Thanks in advance for any help.

Hi, have you guys already flashed the NB8 modem?here it is:
https://www.dropbox.com/s/5jbn672kzzaf85q/I9505XXUFNB8_Modem.tar
Flash it with Odin.
For a TouchWiz based custom ROM ( Echoe V17) flash this kernel in recovery:
https://www.dropbox.com/s/j2twx723izz2apa/[romcook.com]_GT-I9505_Adam.Kernel.2.1.CWM.zip
NOTE: if your phone is Knox free (old bootloader) flash only the modem file, not the non-hlos.bin.
For correct Modem flashing use this guide:

Goto settings/options/device info. What shows the baseband? And what ROM are you using? The baseband should be the same as the ROMbase. So if you are on a NB9 based ROM, you need to flash a NB9 baseband (modem)

You can just flash the latest omega rom mate and make sure your doing a fullwipe so you wont get any problem later. And dont forget to make a backup first incase something will happen. About the modem , if your not having any problem with signal issue after flashing the v2x then no need to flash any modem. And Feel free to check sammobile for the modem you need that base from your country/provider and download the modem/lte from here and flash it via odin .

Best thing you can do is stay on Fn5 modem then flash the latest version of Omega rom , If your having any Dropping signal issue then flash the modem base from your Provider , But feel free to flash the FNC4 modem since that's the latest one for your Country !

Signal problems

Hi
I've had the i9505 for more than a year now, within the week of buying it I installed wanamlite rom with no problems, maybe a little weak on the signal, but nothing major, but a couple of days ago y wanted to try the latest one from wanamlite, but after installing it the signal was horrible, no signal for the most part, I read it could be the modem or something, so I changed the rom to goldeneye, now I have signal but no internet (I have 3g), does someone know what could be the problem and how to solve it?
I have a GT-I9505 4.4.2
baseband I9505VJUAMDE
kernl imperium 1.8
And I live in santiago Chile
Greetings and thanks

Hi mate
the modem you have is kind of old try a different one to see if your signal improves ( no need to change the rom) , check this thread
http://forum.xda-developers.com/showthread.php?t=2192025
To fix your wifi look in the thread for the wifi fix
Odin flashable NON-HLOS.bin (called WiFi FIX) for Samsung Galaxy S4 - GT-I9505
Use it with care!!!
Open in Odin as PHONE!!
WiFi FIX Collection: XXUAMDE - XXUFNC9 - Download: <<<Dev-Host >>>
Thanks for the answer.
But which of all those modems should I install?

well all that depends in what bootloader you have , if you were 4.4.2 before you installed wanamlite you could flash any of the newer ones or
update all modem / bootloader as your knox has been tripped already
