Problem: I9305 not able to connect 4G - Galaxy S III I9305 (4G LTE + 2GB RAM) Q&A, Help &

Hello to you all
this is my first post here, all though I have been lurking around for a while now.
The problem is that my Galaxy S3 I9305 doesn't connect to 4g anymore, both 3g and HSPA+ are working just fine. When forcing phone to 4G it goes into GSM.
Things I have checked:
APN: OK
IMEI: OK
SIM (on another phone): OK
EFS: OK?
Mobile network settings menu: OK
Phone specs:
Model: I9305
FirmWare: KitKat 4.4.4, NEE
PDA: I9305XXUFNL1
CSC: I9305NEEFOA1
- Trilogit

bump
Well it turns out (only thing I have been able to figure out) is that EFS folder is somehow screwed up. I think it's just best to be happy that I'm even having a HSPA+ connection.
One more thing which I couldn't really figure it out from other posts. Is it possible to import stock EFS data apart from IMEI (etc. phone specific data) into my phone from untouched i9305?

[Q] Galaxy-s seems unlocked but mobile data doesn't work

Hello,
I've a Galaxy-S, that I bought in UK from a T-Mobile guy. The phone was working perfectly in uk , I was using it on T-Mobile and everything was just great.
I even updated to Froyo using the Kies regedit trick.
Now I'm back in Italy. I inserted my SIM and everything works well, except for 3and data. I can only use WIFI. For the rest I can make calls, send sms and so on. I don't know why this is happening. If it was locked the telephone wouldn't start with the Italian sim at all.
By the way, I tried to get the unlock code using ADB, unsuccesfully anyway.
What do you suggest?
I forgot to mention:
PDA: I9000XXJPO
PHONE: I9000XXJPP
CSC: I9000OXAJPO
build info: 2010.10
Go to settings, under mobile networks enter the APN settings for your carrier. You can probably find it one the web somewhere.

[Q] In Mexico. Which modem for Telcel?

Serendipity 6.4
Kernel: 2.6.32.9 - [email protected] #32
Baseband Version: I9000UGJK4
Firmware: 2.2.1
And I've also tried
Serendipity VII Build 3
Firmware: 2.3.3
Baseband: I9000TUBJV6
This phone was unlocked and it worked just fine in Taiwan.
I'm now in Baha Mexico, I have a Telcel SIM card, but it just does not work. And I absolutely must get this to work because checking email is critical for me. I don't know what to do. Do I need to update my modem? Which one do I need to update to?
1. My APN settings are all correct for Telcel:
Name: Internet
APN: internet.itelcel.com
Username: webgprs
Password: webgprs2002
MCC: 334
MNC: 020
Authentication Type: PAP
APN Type: Internet
2. I show signal on the signal bar, but no 3G or 1X. It says "Emergency Calls Only."
3. When I go dial the number to activate (*333) I get "Data Network Not Available"
4. When I search for the available Network Operators, Telcel pops up, but if I click on it I get "Unable to connect. Try again later." and "unable to select network. Select automatically." This happens over and over.
5. I called Telcel and it is confirmed that they are still waiting on me to dial in and activate my SIM card, using *333. The problem is, I can't dial in.
AHHHHHHHHHHHHHHH!!!!
Hope I helped
Is your IMEI correct, ive seen that cause problems so make sure you dont have the generic one as that will allow you to connect to some networks but not all, also if you keep having problems i'd suggest odin back to stock (that for sure Works on Telcel's network and if your IMEI is missing it might even give it back)and then update back up SlimBean seams to work quite well for me. Hope i helped, would have answered earlier but just bearly stumbbled on to this thread

[Q] GT-I8190: Can't make calls, no connection to my cell phone provider

Hallo members,
I need help.
The cell phone of my daughter does not connect to the cell phone provider.
The history:
My daughter bought 6 mounts ago an Samsung Galaxy S3 mini. She made many pictures and videos , so that both memories of the phone was full. Than she made an official update vrom version 4.1.1 to 4.1.2. After some days she got problems to make a call. She cant make a call by her self, and also she cant got a call. If she tried to call, the got a notification, that the cell phone does't registred by provider. The phone was not rooted and has a stock room on those time.​
My activities to solve this problem:
I read many threads about brocken IMEI, or problems with base band, but on this phone ist the IMEI ok, also baseband.
At first I made a factory reset.
Second I rooted this phone and flashed an custom room from maclaw. But this does't solwed my problem too.
If I start this phone, I got always an notification message in the top of display, that the cell phone provider does't selected. If I try to search one provider, I see in the phone all available provider on my geo position, included my cell phone provider. This search lasts very long, about 5 minuts. After the search is finished, I try to connect to my cell phone provider, but without occur. I get a message that the connection is not possible on this moment, and I have to connect later.
At last I try to change radio from this thread http://forum.xda-developers.com/showthread.php?t=2548453&page=2, but also without success.​

go to settings - more setting - mobile networks - netmodus - choose auto modus
the go to settings - more settings - mobile networks - third point (the one under data roaming) and choose your provider.
update your baseband to the latest one XXAMJ3 (flashing with CWM or TWRP)

HI, and sorry for my late answer.
I tried to configure like your description, but it dos'n help. Thank you anyway.
What I tried to make also. I installed a rooted stock rom, and update after that to a new radio XXAMJ3, but it does'n help to solve my problem to. I can't make a call, or send a SMS anyway.
Have somebody an idea to solve this problem?
The SIM card oft this cell phone works very fine. I tested it with another phone.
Exactly I am with the same problem. There is no issue about sim card or service providers. It is all about the phone. Please tell me the solution.

You don't have warranty?
---------- Post added at 03:18 PM ---------- Previous post was at 03:11 PM ----------
You may try others baseband versions, If none of them fix the problem it's probably hardware related.
A simple way to do that is flashing different versions of stock firmware, just make sure it's for the right variant GT-I8910 N L T
Is there a fix?
Long story short...
My son's i8190n has been rooted for over 2 years. He has a new phone and I proceeded to update to a new rom. After that I think I messed up the modem/baseband somehow. The recovery is TWRP from maclaw.pl. At some point I even managed to soft brick this phone. I was able to use Odin 3.10 to install a stock rom unrooted.
I can:
* Install any rom and/or baseband
* Leave it unrooted or rooted
* Everything seems to work fine except...
I can't:
* Register the phone to my network
Tried different SIM(s) from different providers, but still no go.
Any suggestions?

[Q] i9305 Not registering to networks?

A friend of mine gave me a S3 to play with and said i can have it if i can get it to work.
Now he doesnt know the original network that it came on or what the original firmware version was.
Before i even tried to get a sim card to work i unlocked it using the hidden menu with sha256 etc.
Now when i put in a sim card it doesnt register to a network, I am in the UK and have tried Three, GiffGaff and T-mobile sims as they are what i have and none of the register to network.
I have a couple of bars signal and the phone says "emergency calls only".
The IEMI seems fine and I have backed up the NV data using QPST and EFS Professional
Device Details
GT-i9305

Baseband Version - I9305XXUEML1
Kernal Version - 3.0.31-2051278
Build Number - JSS15J.I9305XXUEML9
What would be the next step to try?
Have you considered that it may be blacklisted...
I wouldnt have thought so, It worked before when he used to use it ages ago, hes had a few phones since.
He messed around with it quite a lot and has changed the firmware/modems and what have you so much he doesnt know what he has done with it so i presume that its just not set up right.
So anybody got any ideas?
Flash a UK stock rom read the network imei efs stickied posts and work your way through them .
Try your carrier's guide of setting up the correct vpn.
