Problem with network connection on galaxy s3 gt i9300 - Galaxy S III Q&A, Help & Troubleshooting

I'm using a galaxy s3 gt i9300, android version 4.1.2, baseband version I9300XXEMB6. I currently had installed a custom rom ''Sotmax_Ultimate_Stock_V23_XXUFME7_HD_AR'' I managed to install it but when the network service provider requested the handset configuration (picture shown in the attachment) i clicked ok but then another pop up message appears saying ''temporary error occured in application. please try again later'' (picture shown in the attachment) I thought it was probably the custom rom so i reinstalled the stock rom of galaxy S3 but still the problem is there so until now i have no network connections on my phone .....so if there is anything i can do please help

Just go to your provider website, get the apn settings and enter them manually

i dont think it will work because the network connection is telling me ''Emergency calls only'' and the attachment shows the picture of the device's status

Looks like corrupt imei.....have you had the MG4 modem on your phone?

to tell you the truth i am still new to this stuff about android but when i installed the sotmax v23 romi did select the stock modem instead of selecting no changes to be made on the modem

Try ariza patch . Google it. You need to be rooted and busy box installed

You need to provide details of what modem you are on.....I'd your imei starts 0049.....and it looks like it does, then you have probably at some time had one of the new format modems, so you need that (probably MG4) to get your imei back, unless you have a back up of it which I doubt.

Just flash the modem and all should be back to normal

Please go to general > sticky roll-up thread. In there read the imei / efs thread

sim signal problem showing no service

My czn galaxy s2 is working perfectly has xwlpd 4.03 except he detects sim but shows no service for sim...
plzzz help me...
i will be very thankful to u.........
Hi!
Since you are new here, it might be the best time for you to read the forum rules just to get you informed.. http://forum.xda-developers.com/announcement.php?a=81 check it out!
1. try inserting your sim in another phone, if you find a signal in the other phone, then there might be something wrong with the s2..
if there is still no signal, then it is a network related problem and call your network operator
2. if you find a signal in the other phone and not in your s2, then you must flash a modem..
DEFINITION:
*Modem/Radio/Baseband is all the same thing and can be seen by going to Settings - About Phone - Baseband. It's basically a driver which receives and sends Mobile Network signals as well as handling switching between GPRS, 3G, HSDPA etc....... (but not WiFi connection, that and switchover between Mobile Network and WiFi is handled by the kernel). Reasoning as to why Modem has no influence on WiFi can be found in this post by Entropy - http://<b>http://forum.xda-developer...count=6556</b>
USAGE:
*There is no one "Best" modem for everybody. Unfortunately you actually have to try to find the modem which works perfectly for you on performance, strength and battery drain levels. The good thing is that from my lengthy 8 month experience with Galaxy S2, I'm happy to report that there are a few modems that seem to perform well geographically for most users. These modems are KE7, KH3, KI3, KI4, KL1, LPS, NEKF2, NELP2 & NELP3.
COMPATIBILITY:
*Modems do not need to be matched up with firmware like it's done with ROMs and Kernels. For example, a KI4 modem can be used with a KL1 ROM and the other way round. The only thing you need to pay attention to is what model your SGS2 is. 9100 and 9100 modems are compatible across both models. However, 9100 model and US variants are not cross compatible since the devices are designed to work on different bands.
INSTALLATION:
*I will add a flashing guide to post number 5 soon, hence why it says "Work in progress.....". For the moment I suggest asking Mr. Google to do a search for you. Bottom line is, for CWM packaged modems you need to be rooted and have a working CWM recovery (flash the CWM modem zip within recovery). For .TAR packages, all you need to do is flash it while your device is in Download Mode and connected to ODIN. The .TAR file should be selected in the PHONE field. Don't touch anything else.

Because MG4 roms and higher change your efs partition format if you stick above MG4 then your efs wil stay the same, where as if you go below, you will have to repair it and same goes if you wanna flash above MG4

my phone became sim locked after stock rom flash

hi there all - just bought an s3 from someone on gumtree - tried it with couple of different simcards and it worked fine... it had ics on it (csc xxale8) so i though i will change it to jellybean - so following a guide here i have downloaded stock firmware BTU (UK generic) and flashed it using odin. than put a sim in and boot and it asks me for sim network unlock code... any idea what is going on?
FYI i have reset the flash counter before flashing the rom and wiping data and cache
any help?
Some older methods of simlock break after flash. Also latest releases, non of these methods work anyone (the free methods).
I'd imagine you need to buy an unlock code now. If you do, get one that will refund you if it fails
_
I'm assuming you've flashed mg4

You root it before flash?
You make a EFS backup before flash?
Did you already check what imei shows your phone with *#60#
thanks both!
yeah flashed mg4
the ics installed when i bought it was already rooted
i have not backed up EFS prior to flash but rooted and backedup EFS after flashing JB
I have checked the IEMI before flashing which corresponds to the IMEI on the box
any one can recommend an unlocker which will guarantee unlocking or money back?
I think cellunlocker can help you but, if you already have a backup of your EFS folder try to flash others modem here in xda is an mg4 especially to work with all roms, a few days ago I try it because cyanogenmod roms have no signal and after flash that modem it love because give signal to all roms, you don't loose nothing try, before spend money.

Forget modems. This cannot help you now. You need to continue your search for a recommended unlock code provider.
I have the file but I can't post it try to find XXEMG4 modem patched, in the Web or xda developers, if no work, get the code. and remember create a backup of your EFS.

Patched modem is for Serial number 00000000 issue. It is not for anything else.
Like I have already said multiple times, there is only one option.

[S3 GT-i9300][Official Frimware 4.3 XEO] Problem with connecting to mobile operators

Hello,
Sometime ago i had a problem with my s3. It wouldnt turn on, and after pressing volume up+power+home i saw that some files were corrupted. Found the solution here and fixed it. But i flashed android 4.3 xeo while before i had 4.2.2 and now i can't connect to my mobile operators. I know i know, there are lots of topics like this ... are there really? I think i read everything i could find on this topic and tried the solutions but nothing helps.
To be precise:
* have full bars of connections
* i can make and receive emergency calls
* i can't make or take calls
* i can't make or receive text's
* my phone detects all operators in sight and when i want to connect it says succeeded, but in reality it didn't
* i even tried ariza patch, downloaded it and started it but it doesn;t show for me any "apply" or "patch" as i was expecting after reading tutorials,
* my imei is proper and wasnt changed in anyway
* my signal power changes so i quess that works too
Only thing i wasn't able to do is flash 4.1.2 or 4.2.2 because believe it or not there isn't any file on net i could find. All the websites that post having it disconnect downloading at 90% and says to try it tomorrow ( every day ) or buy premium.
Could some one tell me step by step if possible, how to flash newest archidroid (i have it on my other phone and i want it on s3 ) so that the network issue would be fixed? Or at least give me link to working stock firmwere 4.1.2
Thanks alot.
no one knows the fix?
Do not try to go back to earlier firmwares. Why? Modem MG4 repartitiones /efs partition so it finishes with bricked /efs so no imei and calls itp
So, how to flash custom rom? Firstly you need to root your device, e.g cf autoroot way, later flash custom recovery via odin and later its simple, just wipe data in recovery and flash zip (rom)

Your imei doesn't start 0049 or (unknown)?
Also as said by post #2 you shouldn't downgrade unless you can flash the older bootloader and efs v1
Secondly I can link you to 4.3 but you gotta tell us where are you using your phone (just country), otherwise I'll link you without the respective csc, but I can't guarantee the ROM I link won't contain country specific bloatware
Third and last, the two guys above are trying to help and your output is very rude and ungrateful, please know that this is a community forum, the community are the one helping you, again I'm js, don't bash me for helping you too, you can call it backdoor moderating, but I call it letting you know

Guys belive me. I'm not rude, in very polite way i'm informing author of 1st answer that he didnt read my post and answered questions i didnt ask, totaly off topic answer.
To second author i asked how will this device help me.
* my imei is proper and wasnt changed in anyway

And lastly snkmv as shown in the quote no my imei is fine.
Also i do not need links to firmware 4.3 as i have 4.3 and the problem i spoke.
What i ask help with is fixing that problem.
I thought that maybe flashing 4.1 would fix.
So guys pls read my 1st post, read carefully all the bulletpoints and if anyone knows something pls help.
Yes so I commented what you want to do, it wasnt the answer for your question...i read your post... MG4 isnt 4.1? So I wanted to save ur phone bro, but if you know better... Later again if im not wrong NA1 was partitioning /efs so I just wanted to tell you not to flash earlier firmwares to not to brick your /efs totailly. It's not that simple as you thought "I'll install earlier firmware, may it will help, what may happen" - no, that's not on
And now yes, this post is so off topic, but it was just comment, we're here to help together, share advices together.
Bests, have a nice day

ok, so you answered my questions about coming back to 4.1.
and yes mg4 isnt 4.1.
what i dont understand of all of this is why can i make emergency calls but not normal.
