Buying Verizon G2 for use in Europe - flash other ROMS for 4G support?

Hey guys,
is it possible to use one of these in Europe with full 4G support? Can I flash ROMS that are meant to be used on the European model and it will fix the antenna or should I flash specific Verizon ROMS and then flash an european modem, if at all possible? I thank any input because I'm clueless.
Thanks!

1st wrong section
2nd, Not 100% sure on the bands, but you cant flash any other firmware other than Verizon unless its a custom rom, But flashing a rom wont unlock bands.
in us version missing bands totally - physically! it isnt about software but only HW ...

I thought this would be the appropriate section, which one should I use then?

So you're saying there is zero chance of making it work by flashing something?
Thanks all!

Freedompop N900P help

Hi all,
I have a freedompop ( they use sprints network) Note 3 N900P. Since the phone uses the sprints network indirectly, I am not sure which roms I will be able to install. Also the phone comes with lollipop; can i use the cf-root app? It says that it only supports the 4.4 bootloader, but the phone is running 5.0.(not sure if the bootloader was updated).
I would like your advice.
Thanks in advance
The Faqs show that phone as a Sprint model so i would expect the Sprint forum to have the answers .

No one replied; I can confirm that it already has twrp installed. The only thing I am curious about is if the roms in the general note 3 threads will be compatible.
USUALLY any non-exynos rom will work. I'm on ringplus. I just add my APN and done. Tried using Music of life LP rom, though that one is tricky to add apn because it's greyed out with the SPR csc. Use the XAS csc to get apn to work. I'm now using darkera13's s7 edge port which gave me no problems editing my APN. I'm assuming the s7 edge port in this forum might have a similar experience.
Oh and the sprint section was no help for me. I had to figure it out on my own.

are you able to update the prl while on the custom roms?

No, I never could. For that you'll have to try sprint-based roms. Personally, I've gotten a signal just fine without updating prl.

Probably APN. Find out what your cell provider's APN settings are and make your own.

The phone get APN form provider, also i added it manually, but can't get 4G.
I think the problem, is that the phone is sprint and 4G work only in USA, right ?

oh right you're not in the US. If the bands aren't supported then you won't get the data. I don't believe a cdma phone was the right choice to use outside the US. Have better odds using a gsm phone.

SM-G935A in Europe?

Hi everyone, I just wanted to know if is possible to use the SM-G935A model in Europe? I know that USA models are using differend network frequencies so I was not sure...
Also how can I check and know for sure if the phone is carrier locked, and if it is, is there any way to unlock it here in Bosnia?
Should be fine but check what frequencies your network uses and then compare

It supports Band 3, 7 and 20, commonly used for LTE in the UK and Europe.
It also supports both 2G and 3G on all networks in Bosnia.
Since all countries in the EU use the same LTE bands, it'll work everywhere.
Thank you both for the replies.
Which site is recomended for carrier unlock, I have found cellularunlocker (dot)net but I am not sure if it is reliable and safe to use? It costs 25$
I am sorry if this is not allowed to ask on the forums.

You should look for the partition file and debranded rom which should unlock it, that's what I've done in the past anyway

Hello, thank you very much. I will try it and I am familiar with flashing roms, so I will use ODIN to flash a stock ROM which is rebranded. But could you be a little more specific about the partition file, as where I can find them and how to flash it?
Is there a risk of bricking the phone?

Don't know if there are any, but you'll have to find the newest SM-G935A ROM with a PIT file, apparently that removes the network lock.
If you're still hesitant to flash, you'll have to find a reputable cell phone unlock code website. Not sure about them since I've never needed to use one.

Hello, thank you for your help. Just to be sure, the phone is on AT&T so am I right that I have to download the firmware (includes PIT file) from this post No.14: https://forum.xda-developers.com/galaxy-s7/how-to/collection-firmware-rom-pit-files-t3326707/page2
I just want to be sure that those are the right files/firmwares before flashing them?

I don't know how new/old the firmware is, but if the PIT file is included, it should work fine.
Sorry, wrong thread.

So you assumed that the fixing the IMEI would get you your SIM network? Did you get the famous "baseband: Unknown" problem?
Because that's something entirely different... or so I've been told.
What baseband/modem what CSC??

What ROM are you running? Are you on stock? What is your baseband?
All of these questions can be answered by taking a look at "About Device" in Settings

I am on official lollipop
Do you have baseband and CSC correct for your network.
Suggest returning to service center if you don't know .

I had the same problem. Tried all kind of difficult how-tos, but the one which did the trick is just try to flash another Kitkat firmware (one meant for a different country). I bought my Note 3 in Belgium, so I assumed it needed a Belgian firmware. That was not the case. A French firmware did the job!
