[Q] i9505 only getting G/E in mobile data indicator

hi guys im a new android user. i bought my i9505 galaxy s4 3 weeks ago and everything is working perfectly except the mobile data. i can only connect to E/G signals with it (which doesnt really do anything because i cant even check emails). its on LTE/3G/WCDMA/GSM(automatically) setting and the APN is the correct settings with the carrier in my country(philippines). i tried my sim on a different i9505 phone and it was able to connect to 4g so i guess the carrier/sim being the problem is ruled out. i have restored to factory settings/rebooted multiple times and am still unsuccessful. the phone's IMEI is not blacklisted or banned and it is intact(dont really know what that means but it shows a long series of numbers and im not really sure its safe to post it here). My carrier also supports the frequencies listed on what the phone has. i have not installed any custom firmwares and have not re installed any official releases.
i would really appreciate it if someone can help me fix this problem. could it be a software problem or a hardware problem(praying it isn't)?
my phone specs are
GT-i9505 samsung galaxy s4
android version:4.3
baseband:i9505XXUEMJ7
kernel version: 3.4.0-1765174 [email protected]#1 tue oct15 16:14:54 KST
Build number: JSS15J.I19505XXUEMJ7
SELinux: Enforcing SEPF_GT-I9505_4.3_0010
if you need me to put any more info just tell me

Go Settings > More networks > Mobile networks > Network mode > select WCDMA

[Q] What if I can't connect to a specific cellular network provoider (yesss! AUT)?

Hello all,
I want to understand in a more detail how android is working because I have a specific problem with the cellular network.
On my galaxy s4 i9505 I was running a CM11 Snapshot M9 for a while without a problem.
It's ok but I often wanted to update to the latest CM11 builds (Snapshot or Nightlys) but there seems to be a problem with my cellular network.
The thing is, my provider is "yesss!" which is a discount mobile provider in Austria. With the M9 build the correct network is found and automatically connected. On all newer variants there is no automatical connection.
When I search for cellular network providers I only find the bigger ones like "A1", "Drei", "T-Mobile", ...
I can connect manually to "A1" which is a roaming partner of "yesss!" but it won't reconnect automatically and it is detected as roaming (which is correct). So basically the modem is working but there is no cance to find a connection to "yesss!"
How does it work?
I found out that even on the newer builds, the same modem is used.
I tried: I9505_XXUDMGG_MODEM.tar and later I9505_XXUDMHI1_MODEM.tar
both work with CM11 Snapshot M9 but are not working with newer builds.
So it may seems to be no problem of the modem?!
I tried to go to the "*#*#4636#*#*" menu and checked the settings:
on both versions "LTE/GSM auto (PRL)" is configured, so also no difference.
I tried some inofficial CM12 builds and other Andorid 5.0 builds.
Allways the same... The roms are working fine but the can't connect to "yesss!". only "A1" is possible.
Does anybody know what I could do?
Please help. Right now it seems that I am stuck at an old CM11 build.

BaseBand version: I9505XXUGNG2

`maybe your carrier doesn't support LTE. i have this issue too because my carrier only has 3G support. try 3G (WCDMA) it works for me.

Thanks. It has LTE support but I'll give it a try. No need for bootloader or modem update?

S4 I9505 only 2G (E) mode working.

Hello,
I got a S4 and it had a Chinese modem number (ZHUFNB3), I don't recall whether 4G was working there or not on android 4 but what I did was flash crDroid 7.1.1 and kept the same modem, 4G and 3G was not working here, only 2G. Since I live in Albania, I supposed that it's no wonder that the 4/3G was not working with a Chinese modem, so I downloaded an stock firmware built for Albania well Hungary actually (XXUHOJ4) but it started downloading those Vodafone bloatware in my language so it's good. Problem is, the 4G is still not working and the APN is configured correctly. What could be the cause of this? Could it be that I need to take it where I bought it and have those guys change the entire board?
Thanks in advance!

What is the phone's model # in download mode? Does the model # in download mode and imei match the model # and imei on the label under the battery?

I believe it is an issue of the APN. All the custom roms i had tried had this issue. But it was only later (Like 5-6 different rom tryouts that i understood that changing the APN worked. For me it was set to "portalnmms" for my sim by default. Changed it to "www". You can try this method. Settings->more->mobile networks-> Access point names

Nope that didnt resolve the issue.

I think you are having a baseband problem . Even if you flash it you will not be able to change the baseband version. I was having the same problem but if fixed it .
