My apologies if this is already answered somewhere - I've done a lot of searching and can not find it. Do an Xperia phone's usable frequencies change based on which regional firmware is installed? If yes, is there a database or list of the frequencies supported by each regional variation?

Has anyone been able to get the i9505 to work on NTT Docomo's network? I've tried a few different roms and also looked through the different CSC's that are available in the prerooted thread in the android development thread, but unfortunately can't find the correct CSC for Docomo (DCM). I'm also not sure if I have the correct modem file to work out here, the baseband I have on the phone right now is I9505ZHUAME1. Also, I made sure that the apn is correct...spmode.ne.jp
Docomo does offer their own varient of the i9505, it's the SC-04E. From what I have read so far, it is essentially an i9505 but most likely has docomo specific security requirements in the hidden partition. My skill level for computer programming and android programming are quite low, but I'm wondering if it would be possible to extract the modem file and CSC from the SC-04E rom and use it on my phone? Or is it possible to flash the SC-04E rom on my phone?...I kinda doubt flashing the rom will work on my phone and probably brick my phone, just grasping at every straw I can to get the mobile data to work..having to rely on wifi connections sucks lol.
Here is a link to the SC-04E firmware:

Hey guys,
So a family member (FM) of mine received a Verizon GS5 and I was just wondering if it would be possible to change to UK, as far as I am concerned when I owned a GS2 I would have to change the modem for it to work in a completely different country (e.g. owning a UK GS2 and taking it to somewhere in Asia or South America). However, would prefer to have a complete clean install (and possibly a debloated ROM) with a UK firmware? If this is possible what are the steps to folow, do I have to be careful with tripping KNOX and/or flash counter? FM doesn't mind losing data.
"This Sim Card is from an Unknown Source". Just from reading this thread I can see that I either have to root the phone and disable/uninstall the app or install a different ROM, would prefer to have it as official as possible. Tried changing the APN settings and inserting the information manually, unsuccessful. Haven't tried searching for a carrier and letting it set up itself. I don't mean to be difficult, sorry!
Checked here for frequency compatibility, does this mean that 4G wouldn't work?
Thank you!

You need CSC=BTU and a clean stock-like ROM, right?
Have a look: https://forum.xda-developers.com/galaxy-s5/development/rom-ane4-kitkat-4-4-2-multi-csc-t2813628
Installation on G900V is tricky because of locked bootloader but it works fine.
4g may work on B3 (it's supported by device, just not listed in specs) but the chances are not very high.
Hi,
Yep, change the language.
No, it's not that simple as you might think - like open up preferences and choose correct language. Or install some kind of soft that doesn't work properly (not localized to the end).
Phone I'm referring to, is made for US market probably, hence no European languages there. It's SCH-G900P, and from what I googled, it's a Galaxy S5 Sport (for US).
From what I know, best way is to reprogram the firmware with European version. But, but.... I've got few details to find out, like:
* which FW to pick - is that country and network, which phone is operating in ? For example, I need to change language to Polish - so is it a difference between Polish networks (in terms of FW features that I'm going to download) ? Is it more safe to pick exactly the same network firmware, or it makes no difference at all (maybe except some bloatware) ?
* what about WiFi calling feature - for example British BTU and British EE are quite different - first one (unbranded) won't allow this, and second one (EE) - will do, so maybe it's better to use British EE firmware to get more features (and other languages should be built-in) ?
* S5 do have 2 various CPUs (from what I know), does it matter, or all FWs are common ?
Thank you forany clues.
Cheers,

According to SamMobile, the CSC selection for the Sprint S5 (SM-G900P) is as follows.
BST = Australia (Boost Mobile)
SPR = USA (Sprint)
XAS = USA (Sprint)
VMU = USA (Sprint)
XAR = Cellular South
The only other option would be (if it can be done) is to Unlock the Bootloader and search for a way to be able to flash a Compatible Custom Firmware that has the language your looking for like the SM-G900F.
I've never tried this myself on either of my S5 Devices but, see if any one of the following threads/links are helpful.

Thanks for reply.
I don't know how it happened, but apparently I had unlocked bootloader as I was able to install TWRP and flash custom kernel with no hassle.
Now looks like there's only one custom firmware that supports multiple languages, including Polish: Beanstalk (thread present in Sprint S5 group). However I can't check the rest of its features as Pixel Launcher constantly hangs up.

I'm not sure but, I had thought that the LineageOS has a multilingual feature...
You can always ask this question within the following Official LineageOS thread for the klte variants.
https://forum.xda-developers.com/showthread.php?t=3680666
Just keep in mind that the LineageOS for your device is the "KLTEDV" and the above thread is the support thread for all variants that doesn't have their own Official LineageOS thread (like yours).
If you need to, you can always try to obtain some member guidance within the following Q&A thread that's specific to all GS5 devices.

Hi,
I noticed recently that the Galaxy S10(+) and its firmwares are quite similar, if not coming from a network operator.
To illustrate this, I would say for example BTU which is stock UK has the same PDA and CSC numbers than French stock XEF.
How is this possible?
What's more, the phone seems to automatically know which code to use — after flash it will display on the 'About' tab the code related to your country, independently from what country-related S10 firmware you decided to download.
It can't be fooled anymore because as far as I remember you could flash other firmwares with different country codes so that you would sometimes get updates faster.
Or I might be just wrong.
@ThomasM6
Regardless of the branding, the available network bands are similar, if not exact, through Europe, Middle East, Africa, Southeast Asia and Oceania so that a one size fits all approach works on a hardware-level.
This same methodology is in place when it comes to firmware.
To an extent.
To demonstrate my point, I've attached a file called 'product.map' which I've extracted.
(I had to rename it to 'product.txt')
Inside that file you will see almost every major telecom company across EMEA and APAC listed.
It is using this file, alongside a combination of .info. txt., .dat, .xml and others across the operating system, to isolate the Carrier based on the SIM card inserted.
If it does NOT locate the appropriate telecom, it defaults to native country where it was intended to be sold.

A number of users have stated the software now matches the SIM's CSC so flashing the device is no longer necessary.
Some are still having trouble selecting the correct active CSC in a multi CSC firmware

Hello,
Yes, I've read and read again and searched as much as possible, but strangely enough changing CSC is not widely covered as root, for example, and I still have some questions.
So, as the subject says, it is a Latin America variant with dual sim and Panama (TPA) firmware. I can't specifically say why, but I feel like I want to change that. Perhaps faster updates; maybe ability to use functions that currently I can't (Samsung Pay?!), etc.
I am in the U.S. with main sim from TMO and second SIM from Israel. Current Service Provider shows
TPA/TPA,ILO/TPA
In Phone Info app I see the following:
Active CSC is TPA
Firmware's CSC is XEF.
1. What is the difference between the two (Active and Firmware)?
Note that I did not do anything out of the ordinary: activated the phone new out of the box, it downloaded some updates (before I put my SIM in, if that matters), and that's about it. So why would a Panama phone have French CSC and how come I don't see XEF anywhere in the phone info itself (only in this app)?
2. Is there a 'better' CSC to have compared to others, in terms of frequency/priority of updated, available services, etc? Phone Info shows a list of available CSC's to chose from (see below). As far as I can tell, the only two things that don't work for me are TMO Video calling and Samsung Pay. Will different CSC enables these services for me?
3. Are there any downsides to changing my TPA CSC to a different one?
I am sure I'll have more questions and I appreciate any assistance.

The Phone INFO App doesn't always reflect the actual firmware. Try Settings, About Phone, Software Information, Service provider SW ver.
Samsung Pay can work on the Exynos European variants but I haven't seen it working on any Latin American variants.
You definitely won't be able to use T-Mobile Video Calling on your firmware. Your only hope on changing the CSC is rooting the device however you'll trip Knox and lose your Secure Folder. It's an "Iffy" option and I wouldn't recommend it. You might want to review this thread for additional info, good luck!

Thank you @varcor.
Rotting is definitely out of the question, I don't have any interest in doing that.
What defines the phone as European vs. Latin, when both phones can accept (technically) any OXM multi CSC f/w? Is it the CSC itself (the last 3 characters after the sim info)?
BTW - INFO app shows the same details as About Phone (in my case).

It's for software compatibility for the most part, the hardware is identical with a possible exception in cameras. The CSC's will be different as well and they do affect software configuration. If you read the last few pages of the link I've shared you'll see some members claim they're having success changing their Active, SIM 1 and SIM 2 CSC's using Samkey, which doesn't require root. Remember the 4th CSC (Sales Code) can't be changed regardless. How well Samkey works on individual devices likely depends on the device, it's associated firmware and Service Provider. Not an interest to me as I mentioned since my device aligns and incorporates calling features based on the Active SIM for the regions I've visited. I have T-Mobile as my carrier which works with Telcel (Mexico). I'm surprised I don't need Telcel SIM for calling features, T-Mobile has eliminated that need as I get Wif Calling and VoLTE on Telcel's network.
