[Q] ROM with default latest baseband + LTE support?

Hi,
I couldn't find anything related to this on the forum so here it goes.
I know that google has disabled LTE support in latest baseband release. And one would be able to flash the old baseband to regain LTE support. However there's many steps that one need to do to get it enabled (type in service code, change LTE setting, enter APN etc.), not to mention you also loose some enhancements/bugfixes.
So my question is that, is there any way one can build a custom ROM + modified latest baseband (4.2.2) to have default enabled LTE support directly? (means no service code change, APN change etc. and with all the possible enhancement from the baseband build)
If yes, please direct me to the post or instruction, if not, why not?
Thanks for answering!

You can just use the old baseband and have LTE on any ROM.

Thanks for your reply. Yes, as I stated in my OP, I'm well aware of the ability to use old baseband on the other ROMs to have LTE. However, I'd like to have LTE on latest baseband, and also native LTE support without fiddling with the settings.
I would like to learn how to do it if there's no one already doing it, just need some direction to the right documentation/guides or explain why its not feasible.

I don't believe the baseband software is open source. Since the LTE functionality was removed from the baseband itself, flashing a ROM is not going to restore it to the .44 baseband.

I see, that's what I'm afraid of, so I guess the best one can do is pack a .39 baseband with custom 4.2.2 ROM with default LTE configuration then? So I guess my follow up questions is how much of the LTE operation is controlled by the basedband module?
Can a ROM have LTE as Preferred Network setting?
I think its possible to have default APN configured baked into the ROM?

[Q] 4G connection gone after Omega rom.

I have the Canadian Note 3 from Wind Mobile, which runs on AWS network. I was able to get wifi back working after flashing the kernel, but i still can't get 4G back. I tried setting up the APN, but still no go. Does anyone have solution to this?

bump! help please!

In which area did the OP of OmegaRom say that the ROM was compatible with the N900W8?
In any case, think about this...
Kernel: Controls system modules like the Wifi ✓
Baseband: Controls the communications between the network and the device. ✖ (try this)
If even flashing the baseband, you don't have your LTE back, then you know what you gotta do.

[Q] - i9507: No service on KitKat - Can receive calls, can't dial (no service)

Hi Guys,
I'm from Australia and recently bought an Optus Galaxy S4 4G. Strangely, the model number is i9507. I double-checked this online and usually weird model numbers are just carrier-spin-offs. So I went ahead to root and flash just like you would with an International i9505.
So far no problems - 4.3.x PA rom works absolutely fine.
BUT:
I've tried some Kit Kat roms recently and they all flash fine but give me 'mobile network not available'. Strangely though, I can receive calls/text and talk on the phone, but when I try to dial or send text messages, I can't do it. My reception bar is completely empty as well.
WiFi is totally fine, just no data and mobile network
I've tried messing with the 'network operators' setting and if i select my carrier (I have a Vodafone sim) I'll get network reception until I turn off the screen and then my mobile network becomes unavailable again
Not sure what the problem is; modem? APN? or roms not suitable for my phone?
Current info:
ROM - [ROM] KOT49H【4.4.2】 GOOGLE EDITION 4.4.2 by Danvdh, Kryten2k35 & Ktoonsez
Baseband - i9507XXUAMH2
Kernel - [email protected]oonsez-VirtualBox #1
I've been flashing for a while now but it's usually just basic stuff so you can probably tell I'm pretty amateur lol.
Any help is greatly appreciated!
Thanks =)
Richard

Hi Rich
As your baseband is quite out of sync with the firmware you are trying to run (MH2 is from 4.2.2 ,,, right?) I would suggest you change your baseband (modem) flashing an equivalent to the ROM firmware from here.
I've got yesterday the exactly same behaviour when finally and reluctantly I've added a data plan. I was running a successful low-baseband + high-firmware because was setted to "GSM Only" (try it ... will work flawless). When I've switched to LTE got what you've described in the face too . I've promptly updated my baseband and now all is fine :angel:
EDIT: please do nothing of the above described BEFORE taking a EFS backup with every tool you can find and preserving them in several highly fortified locations and 2 or 3 K7 Tapes too . Have an ODIN flashable copy of your MH2 baseband is advisable too.
Hope I've helped and please share your experience.
Nice regards.

Hey thanks for the reply! Helps heaps =)
While I still had those roms installed I did try flash a few modems within Odin, all failed though =S
Which one should I be flashing?
I believe I tried XXUFNA1 but the flash just doesn't go through
Does it make a difference which rom I flash the new modem from? I.e. flash when the new modem now or flash the new modem on the kitkat rom?
I'm currently using Pacman 4.3.1 since it's perfectly fine. Just can't wait to get on a KitKat rom though! haha

Hi Rich
Sorry, may be my fault, but quite didn't got your
You may proceed having the below as a rule of thumb:
Your baseband (modem) version should always match your ROM (firmware) version.
Failure to flash something is never good signal. As you have an i9507 (I own the 5) is very advisable to flash a modem built for your S4 flavour.
The above rule should apply to it too so, if the only modem available for the i9507 is the MH2 your firmware have to match or these issues reported will return.
Did you tested the "GSM Only" option to corroborate (or not) my hyphothesis? With this config, you should perceive no signal drops when waked. I know it isn't a viable operational mode but ... just for fun
Nice regards and keep sharing :laugh:

If you dial *#*#4636#*#* do you get the testing menu? If so, go into Phone Information and check you are set to LTE/GSM auto or similar.

Sorry to bump old thread but I do not get any testing by dialing *#*#4636#*#*. I am on official stock kitkat.

If you input that code in the dialer (correctly) it should take you to a screen called "Testing". If it doesn't then there is something wrong with your phone. This works on pretty much all phones.

@GDReaper: The Galaxy S4 does not recognize that particular version of the USSD code. It can be run however through the Phone Info app.
@khsh97: Please post the following information:
1. Model Number
2. Android Version, found by going to Settings > More > About device.
3. Firmware Version (AP, CP, CSC), found by dialing *#1234# in the dialer or by installing Phone Info from the Play Store and running it.
4. Service Provider
5. Country
6. Is the phone rooted? (Yes/No)
7. Is a custom ROM installed? (Yes/No, and the name of the ROM)
Before using GDReaper's suggested method, post the information requested, so that we can eliminate other possibilities for why you don't have a LTE option.

I ran the code before posting and it worked on my S4. However, am running the gpe rom. Maybe that's why it actually worked

That is probable, as I'm running a rooted and debloated Touchwiz and it didn't work. But as mentioned, the Phone Info app is another way to get there.

Sorry for late reply!
Model No: GT-I9505
Android version: 4.4.2
Firmware: I9505XXUGNE8(official stock)
AP: I9505XXUGNE8
CP: I9505VFGGNE8
CSC: I9505VFGGNE2
My phone is rooted with towelroot however the option was missing before root as well.
BTW, I don't have LTE sim, does that matter?
If that matter then how can I check without LTE sim?
And yeah, the code *#*#4636#*#* is not working in my galaxy s4.
I am going to check out phone info app.

If you don't have a LTE SIM, you won't have LTE as an option. Upgrade your SIM to a LTE version and you should then be able to select LTE.

Ok, thank you...!!!
By the way, why the code is not working on official touchwiz roms?

Ask Samsung that question, but don't expect an answer. There could be a multitude of reasons why Samsung disabled it, but unless they pony up a response we'll never know.

Lol, Nice answer!!! Anyway phone info app can do it so why we should argue with samsung for disabling that code.

I think you must have firmware based on your country to have LTE. Now I'm downloading 4.4.2 for my country and I'll keep you posted

@velizarcho123: And you'd be wrong. LTE depends on two things: having a LTE-compatible SIM and having the proper frequencies in the radio chip to pick up LTE service. Assuming the device is neither region nor SIM locked, the moment you put in a LTE SIM Android will load the APN for the carrier into Settings. LTE should then work immediately. If it doesn't, the APN can be modified in most devices so it does work.
That said, if possible, using the firmware from your home region is the smartest idea, as Samsung does modify the firmware a bit, usually by removing languages other than those spoken in the region.

All firmwares have LTE, I does a trick - rooted my phone and modified a system file that enables LTE in the network menu. This is stupid Samsung restriction.

Reread my post. You were able to modify the firmware, but that modification would not have worked if the SIM wasn't capable of LTE and the radio chip didn't support the frequencies used.
EDIT: Just to clarify, Samsung modifying firmware to remove the option to use LTE does not mean the firmware doesn't support LTE. Clearly it has to support LTE if your modification worked. This means that firmware is eliminated as a variable, leaving the two remaining variables as the SIM and the radio chip.

[Q] LTE RF issue on N9005

Hi. I'm trying to select RF LTE Only using secret code "2263" via *Phone info* app but my Note 3 is not selecting that option and if I select LTE/gsm only mode then my network switches to edge network.
What shall i do in order to use LTE on my phone.
I'm running Lollipop 5.0 also tried to flash Modem with the older versions but no success till yet.
What could be the possible issue. The LTE coverage is strong in my area though.

No but previously when I was using kitkat XXUGNG1 I was facing the same issue.
Can you recommend which firmware is best in terms of signal recieving and stability?
Mine is a BTU version though.
