[Q] Modem help Please - Galaxy S 4 Q&A, Help & Troubleshooting

Hi Guys
so i'm currently running:
baseband i9505XXUBMF4
and i ger LTE and data reception with foxhound rom ..
however with some roms i loose my data connection ... i get cell and wifi but no data...
I tried the 4G LTE switch it app. and nothing ...
so what baseband should i be flashing with ?
how should i do it ?
please help
thanks

I think the foxhound rom isn't compatible for that... try flashing your stock rom maybe it will return the connections....
Sent from my GT-S5360 using xda app-developers app

Or extract the modem file from stock firmware

Similiar Issue
Here's some steps I went through to investigate this issue. Don't get your hopes up, I don't have a solution.
You can use service mode to lock the phone to LTE and get a better view of what's going on.
Dial *#0011# to get you into service mode. Then you want to go up a menu (there's a bug here). Hit menu>back (nothing will happen), then menu>keyinput then type 1 and hit ok. Select option [1]>[6]>[2] from here you can lock to LTE by hitting [4]>[2] (Telstra run LTE on Band 3 = 1800MHz). Reboot for good measure.
Exit and Dial *#0011#. If your phone works, you're now looking at some low level LTE RF stats. I have 2 GS4's which are showing me strong coverage. If you phone is like my third GS4, it'll say No Service.
I can lock that dodgy one to GSM or WCDMA with no issue.
So, off I go to flash the modem to within an inch of it's life...

No data connection after rooting to custom rom (Darky's v5.6)

I'm new to flashing custom roms and what not. I used odin and flashed everything to the point, csc, modem,pda,pit the rom works awesome but i cannot for the life of me connect to the internet. the 3g icon or h icon wont' show up. in the status it says my network type is gprs and i'm roaming and my mobile network state is disconnected.
I'm with fido, the phone is unlocked i have never had trouble with data or anything until i flashed to a custom rom.
Anyone have the same problem or suggest how to fix?
Data Conn. Issue
Hey mate,
Have you gone into 'Settings', 'Wireless and Networks', 'Mobile Networks' and then 'APN settings' and entered your appropriate settings?
That should fix it if you define the correct access point.
Alex
hey man, yeah i did all that stuff, went in there, found my carrier, put in all the apn settings i can find and still nothing. when i put data roaming on then i get data and the edge icon comes up.
Hey dude,
That sounds strange, flashing custom (or even release) roms is never a guarantee especially with weaknesses in the way that ODIN communicates with your phone, What I would do is Re-Flash your stock rom through ODIN then use the "quick" install method from Darkyy.
I am running 5.6 like you, and I had issues doing it through odin (I kept getting random FC's), additionally, the rom; if installed from CWM will keep your apns and apps e.t.c. along with many settings and configs from the base rom you're using before the flash.
That is the best advice I can give you.
Alex
My config is a follows:
I9000 International
16gb SDHC
500HZ Hardcore Kernel
Darkyy 5.6
Whats the process for reverting back to stock 2.1 eclair rom?
Did you keep a record of your firmware version before reflashing?
If not, you may have to ask someone on here what your base firmware was.
Are you familiar with using ODIN? (The software used for reflashing)
Alex
I am having same issue to...I used 5.4 from Darky and it works well...same with DocRom 4.0 works and the next 5.1/6.0 don't work.
Both Darkys and DocRom are based some JPX....which seem to be root cause..
I've have the same problem. Tried eveything but still didn't work. So went to Samsung Service Centre to have my SGS firmware refresh. I notice after the refreshed same issue of data com missing. Told them and they when into the SGS to select the telco operator setting selection. Now data com. working well. Anyone know the SGS handset setting code? I want to reload to Darky's v5.6 again.
hi folks
i have the same problem... my provider is a virtual provider in the network of our biggest provider here in austria. i was using doc's rom based on xwjpa firmeware and everything worked fine without enabled roaming options.
since doc's rom is based on the newer releases (xxjpx, xxjpy) i' only able to use data connection if i turn on roaming. it also shows me that i'm in a roaming network. i guess the cause are the xx firmwares. xw and xx are european firmwares but i do not know the differences between them. maybe someone has more information about the differences? currently i'm using xwjpa firmware because i don't want to use my phone with enabled roaming options.
hey um i'm having the same problem and thought replying here would be better than starting a new thread.
well i installed the rom without having any idea of what i was doing *stupid idea* so i didn't take note of my original firmware.
i didn't use odin to install the rom just clockwork recovery and the rom and everything installed fine except my data network. i can get signal, call, receive the only problem is i get no data transfer. any help much appreciated. if anything can someone help me step by step to reboot my phone to original?
just for future travellers
Sadly this isn't my own gem, but yeah. hold the power button down, wait for the shutdown menu, above the airplane mode there is a data network button, and it'll most likely say "de-activated" if nothing else has worked. Its ok to feel like a chump, I did after rehashing the hell out of this phone for a few days ( the wifes phone, my phone does exactly what its told. )
Anyway, yeah, this will probably be the reason for the lack of the icon "G", "3G" or "H" where it should be.

LTE/WCDMA/GSM setting restricts mobile data

Hello. Im running Kitkat 4.4.2 Goldeneye rom. NBE modem. I am encountering a problem with my mobile data. Whenever I choose LTE/WCDMA/GSM I get a brief connection to H or LTE but after a few minutes (random) it goes away and doesnt return after ticking on/off.
My temporary fix is just using the WCDMA only option. Anyone encountered this problem? Would provide more info if needed. Thanks in adv for your help.

GT-I9500 dropping from H+ to 3G and not going back

Hi, I'm from India and have a GT-I9500 which has been running flawlessly for the past 1 year on BSNL service right up to OS version 4.4.2 firmware vers. I9500XXUFNE4. Since then I upgraded the firmware twice to I9500XXUFNG1 and subsequently to I9500XXUFNI2. Midway while using firmware I9500XUFNG1 in rooted version, I started noticing that my phone data would run normally for a while and then suddenly the data connectivity would drop from H+ mode to 3G but would not return to H+ even though I know that I am in an area that has consistently strong H+ signal. The only option to get H+ mode back was to go to Settings/More networks/Mobile networks/Network mode/ and change the setting to WCDMA only mode for two minutes and then switch back to WCDMA/GSM(autoconnect), then the phone would get H+ service back again for a few hours. I thought that it might have been some problem caused by rooting, so when the latest firmware (I9500XXUFNI2) was released this month I upgraded the firmware but since I lost root on upgrade, I did not root the phone, fearing the problem will come back since I thought root was causing it.
Now in stock firmware running on I9500XXUFNI2 I am still getting the same problem of the phone dropping to 3G mode from H+ and not reverting back ( the speed is not even 2G. Just the 3G icon shows it - data packets hardly get transferred) and I can rectify it only by switching to WCDMA mode and back to autoconnect, as previously stated.
I checked online for solutions, but I don't seem to see anyone facing such an issue.
I thought it could be a service provider problem, so I used SIMs from Idea and Airtel as well, but while using those networks also, the same problem persists, so I have deduced it is a problem pertaining to the phone only. Not sure if it is a hardware malfunction or firmware based.
Does anybody else from India running the latest firmware for GT-I9500 have similar problems, and is there a solution?
Thanks.

The problem is with the modem firmware. Change it back to the original or get a kernel.

Thank you, Devilslasher. Could you please link me to a thread where they have listed the original modem firmware? I did a search under the Samsung S4 subsection on xda but could not find any thread where modems/radios for Indian version was hosted.
Thanks in advance.

Moto X Play India version accidentally changed

Hello guys, I wanted to change my data setting to wcdma(3G) only because my phone keeps on reverting to 2G so I did some research and found an application in playstore called Network . I was going through it and there was this button called Radio band if I'm not mistaken , I pressed it and instead of pressing the back button I chose USA band, now my phone is not able to receive any network, please help me I really need to get my phone working again, if there is any way to revert it back .Please leave some comments . Thank you
I am having same problem. Please reply if you got anything.
instant solution...factory wipe it from recovery.
otherwise you have to do it by dialing *#*#4636#*#* . you have to select wcdma or your preferred network..otherwise easiest way is factory wiping.
edit: after dialing go to phone info then top right corner 3 dots and select radio bands and if USA band is active deactivate it.

Try reverting it back from that same app

No way to revert from same app. I was forced to re flesh official ROM on my device. It's working fine now.
