Hi! I have a N900W8 from Claro PR. I'm not new to flashing custom ROMs but this phone has definately given me some problems. I've tried just about every Rom available and every modem and I can't get better network speeds. I flash everything step by step (WiFi/BT Fix and everything else needed so that N9005 ROMs work on this device) and still no luck. I've even flashed the Original Claro PR ROM from sammobile and my internet speed is still very slow. It wasn't like this when the phone was brand new (untouched). Is there anything else I need to change or fix ? APN settings are correct (I've triple checked). If anyone can chime in with any information it will be greatly appreciated.

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?

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 =)

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:

Hi all,
I recently bought a Galaxy S4 337M that was rooted and loaded with a custom ROM. I decided to go back to stock so went to sammobile.net and got the latest rogers firmware for my galaxy S4 (which they said was 4.3).
I loaded with ODIN, all went well, rebooted stock, but the max signal icon I can get now is 4G (even though I used speedtest and am getting close to LTE download speeds I think). Any idea why my LTE is gone ? Did I download the wrong ROM ?
I also noticed that none of the APN settings were there and no rogers apps were installed either. Makes me wonder if it was indeed a stock rogers rom after all.
Another strange thing is that it shows me a bell canada navigator update is available in the google play store, yet its not even on my phone. Regardless, even if its a Bell ROM by some chance, Bell Canada has LTE as well, so I am confused.
Btw I used the standard ltemobile APN settings that I always use on all my phones to get LTE (that always work)....
Any help or suggestions would be really appreciated, thanks so much !!!
My iPhone shows LTE using the same SIM...
PS. If I do need to get an original Rogers ROM, is sammmobile not the best place lol ? Any other places to go??

I believe that all I337M uses that same firmware but you need a CSC changer to make it change to your carrier as they don't release the specific ones with the carrier apps.
Search "Samsung CSC" in the play store and you should get one.
Thanks for the reply.
Seems I need root - which I deleted when doing a factory restore.
The strange thing is that it was supposed to be a rogers based firmware that I downloaded and flashed.
Maybe something went wrong in the flash.
Will try again.
And check out the CSC
i have a bell i337m and i have the same issue when flashing from a "custom rom to stock" and i have to flash the firmware using odin a second time and than i get my LTE icon enstead of the 4G icon, sounds weird and i can't explain why it takes 2 flashes to get it to show up proper, but it does.
i also have the problem with missing phone vendor apps, the second flash also makes these show up too.
also another thing i noted about my phone is if i don't root and install recovery to wipe, odin will dirty flash my roms, even though odin is supposed to wipe it isn't.
i've tested this to no ends, the results are 100% the same everytime.

After flashing the stock Rom, go back into stock recovery and wipe data and cache, then reboot that should fix it. To fix your csc issue there is a way to do it by dialling a number on your dialpad which includes your imei number then you choose a specific code. Search for it, google

Thanks so much for the replies and help.
I wiped the rom just for fun and rebooted and noticed that its actuality a BELL ROM (all stock BELL apps etc), but when I entered my rogers APN settings it still only showed H+, maybe due to network differences. It's frustrating because I specifically selected a Rogers S4 ROM from Sammobile.net. Any idea where I can get a stock rogers ROM for s4? Also do you think this may have affected my 4G/LTE issue ??
Either way, I will definitely flash the correct ROM twice, and then go back into stock recovery to to wipe data and cache.
Thanks again for all your help

THAT WORKED
Thanks so much !!!
Hi,
I recently was getting frustrated with the ROM Gummy. ROM GUMMY: (http://forum.xda-developers.com/showthread.php?t=2563973) so i wanted to try something new and never thought i'd get a problem as when i flashed GUMMY it was so simple and everything worked.
However, when i flashed to the ROM S4 Google Edition: (http://forum.xda-developers.com/showthread.php?t=2544474) i noticed my signal / network won't stay connected. It may work for 2mins then disconnect - so i tried another ROM thinking it was caused by the S4 Google Edition.
I'm now currently on KOT49H【4.4.2】Google Play Edition (http://forum.xda-developers.com/showthread.php?t=2557353) and still getting no signal, only if i keep changing it to automatically find a network.
I've been reading it could do with Modems, or have i really messed something up and won't be able to fix my phone? I'm sort of new to this all so if you could explain more than tell me to do something that would be great.

You have to flash a new modem for 4.4 like nb9. If you have a bootloader without knox, flash only the modem.bin file. If you have knox, flash modem and non-HLOS.bin. there's a nice modem thread in the general section.:good:http://forum.xda-developers.com/showthread.php?t=2192025

Hi
I'd be grateful if anyone can offer any advice about very poor 3g speed. On my S5 my data connection fluctuates between 1mb and being so slow it cuts out. The same sim card in my iphone gets a steady 3mb so I know the problem is something to do with the S5.
I'm not sure if it's something that can be configured manually or if changing the modem or kernel will help. I'm not too knowledgeable about these things and am a bit nervous to mess with them when I don't understand what I'm doing.
My phone is on BOA3 modem with a BOA3 Lollipop rom (Ambassadii's rom). It had the same data problem on the Odin flashed stock Lollipop. Should I try a different modem and can anyone suggest which one please? I'm on giffgaff (o2) in the UK.
Thanks
It seems that I can't get any mobile internet connection whatsoever on any Marshmallow ROM.
I have tried different roms, I've tried over 20 baseband versions (modems) to no avail. I honestly have no idea what to do anymore and can't seem to find any fix to this.
If anyone has ANY idea and thinks that can aid me anyhow, it would be of great help, thanks !
Select the correct APN.
Mine doesn't connect with the default APN either.
