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

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.

Network Unlock/update for AT&T Samsung Note 3 (SM-N900A) topic

Hello,
I got an AT&T Samsung note 3 (SM-N900A) from USA and i want to use it outside Europe and US, the Note have the following specification:
Model number: SAMSUNG-SM-N900A
Android Version: 4.4.2
Baseband Version: N900AUCUCMLG
build number: KOT49H.N900AUCUCMLG
Version:
AP: N900AUCUCMLG
CP: N900AUCUCMLG
CSC: N900AATTCMLG

I successfully root it by using Geohot's Towelroot app :) . but when I tried the Chainfire's RegionLock Away v1.3 app it didn't work for me ( since I no longer have the AT&T SIM card) :( .
I also tried to use the service mode ( *#197328640# ) method but I couldn't find phone control screen :( .
so I tried to Install Custom ROM (build number: Dynamic Kat 2.0) using Safestrap, it worked fine for an android system but after repeating the above methods didn't seem to unlock it :( .
the Note seems to read the new SIM network but can't register on it or read its internal saved contacts :eek:
So can I update the modem of this device to an international modem without bricking it? and how to do so in a Safe way?
is their a other way to SIM unlock it ?

Excuse my little knowledge, I'm new in the android world :confused:

I really need help guys, any suggestion will be helpful, thanks alot.

[Q] Att Note 4 issues with tmobile network topic

So I bought an Att note 4 unlocked I bought it knowing I might have internet issues but it was cheap, and I'm having issues with the Internet it works fine its fast(not as fast as it should be) just very bad signal and constantly looses connection and searches for network I checked the apn it's on tmobiles network all looks fine, I'm guessing it might be the band issues but I'm using METROPCS which uses Tmobiles network I had a G3 and G2 pervious to getting the note 4 both where from tmobile and never had a single issue with those I would always get full signal never dropped a call not only that I would get download speeds and upload of over 30mbps now it's taken a dump. Any suggestions? I despise att because I use my network a lot away from home I was averaging 150gb a month on my G3 now it seems that it will be hard to do that with this phone pretty bumped use Netflix a lot watch movies online download games etc. :crying:

N900T Network issues, firmware or hardware? topic

Hi Guys!

I recently purchased a used Galaxy note 3 Tmobile variant model N900T. The phone was sold as unlocked and the seller assured me it was fully functional and recently used on the T-mobile network.

Since I received the phone I have had severe network issues using my T-mobile simcard. The network issues are as follows.

Data network stuck on EDGE.
Voice Network disconnects usually after the first phone call, the phone call itself will not disconnect and is stable but once it is ended the modem seems to lock up or reset i'm not sure which one but it could be an hour or more before the voice network will come back. Sometimes a reboot of the phone helps but not always. When this happens I will receive a NOT REGISTERED ON NETWORK ERROR or OUT OF SERVICE AREA.
NOTE: As I'm writing this it is 2am, in LA, California and I have just managed to make 5 calls in a row with no disconnection which is a first! I have noticed however that there is no data service, not even edge, could this be related in some way?


I have done the following.

Contacted T-mobile, they checked everything including IMEI, APN settings, and confirmed no blacklisting or network issues.
Checked that the IMEI number on the label and OS match.
Replaced sim
Tested the phone in different high signal LTE covered area's (Los Angeles)
Used my current sim in various phones, S3, Iphone4, S3 mini. All without voice or data issues, apart from the international S3 LTE which was stuck on EDGE also.
Re flashed various official stock T-mobile firmwares using ODIN. Such as N900TUVUDNF1, N900TUVUDNF4, N900TUVUDNF9, N900TUVUDNK3 and I also believe N900TUVUCNB4 with similar results.
Currently using N900TUVUDNF4

I have pretty much run out of idea's at this point, and decided to post here as a last resort. The seller is telling me that the phone has always worked fine for him and that he does not take refunds. Its all quite suspicious I am starting to believe that this phone has some kind of intermittent fault on the modem. I am hoping there is something that I might have overlooked on my end or some kind of test I can perform here to confirm a hardware fault.


Thanks for the support.
