I bought a used factory network unlocked S3 i9300
it had 4.1 , i downloaded 4.3 from Samsung-updates.com and i flashed the stock recovery and stock firmware using odin (i downloaded the first one "GT-I9300 NZC I9300XXUGNJ2" (i think because my phone is not tied to any network operator i cold choose any firmware)
i followed this guide http://forum.xda-developers.com/galaxy-s3/general/fix-s3-to-factory-unroot-stock-recovery-t2323847
every thing went smooth and good now i have android 4.3 but the problem is that when i call a number i get not registered on network
i'am confused why is this happening ?
i had seen some pages on the web that say root the device and install custom recovery then flash a modem file...
i dont want to root my s3 , and why the hell it is not working and i'am using Samsung stock firmware why do i have to flash a 3rd party stuff to make calls working !!!
note: the IME after update is correct

Rooting your phone doesn't change your firmware.. You're still on the stock firmware unless you flashed a new rom. Goto settings>about device> and see your build.. Then goto Sammobile and downlaod the rom that is listed for Panama and matches your carrier or build whichever. Download it and flash it rom via Odin and you'll be unrooted.
though i don't see any point in unrooting. Rooted is always better.
Hello Guys ,
I have the international galaxy s3 version ,
i'm now runing cm 10.1 with googy max kernel but i want to revert back to stock , but when i go to sammobile and choose my country from the list (Egypt) the latest version is 4.1.2
so my question is , can i choose another country like UK for Example and flash their 4.3 firmware or not ,
my dad also has a stock s3 which updated itself to 4.3 OTA , so can i download any version and flash it or not
although can you tell me what is the latest one i know its 4.3 but the one with the latest modem and csc and stuff as i cant read the firmware letters and searched for a describtion and didn't find any info (XXELLA , XXEMA2 , .. etc )
another question , is there any mod that switches between 2g/3g networks , like the one in cyangoenmod that switches between network types with one click , i searched but all i can come up with is the play store shourtcuts to network setting
last simple question , what is the best kernel for 4.3 ??
Sorry for long post and questions

For your rom question: yes, you can flash any unbranded rom (GNA7 build is considered the latest one), but if you're planning to root your device, then I suggest flashing a custom rom (there are a lot of GNA7 builds available in 'android dev' thread)- they also come with a variety of modems to choose from (I personally prefer the MK6 modem)
About kernel- there is no 'best' one, it depends on personal requirements...

If you're going back to a stock ROM, then the 2G/3G settings can be changed in the Mobile Data options, I can't remember the exact name of the options as it's been a while since I even looked at it, but you'll know when you see it, hope this helped.
Hi guys, im new user on creating posts lol, im from latin america, so my English its not very good, well, i have a problem with my Galaxy Xcover 2 GT-s7710L, when i flashed the official rom (downloaded from sammobile) from chile, jelly bean 4.1.2 (S7710LUBAND2) i was getting normal results, everything was right, but some days later, my mobile data (only internet) stopped working, so i thought that it was some problem of the rom, so i tried flashing the guatemala rom (S7710LUBAMC2_S7710LTFGAMC1_TGU) and when i go to the phone info, i realize that i have the base band XXXX, but my imei is right, and my mobile service is working, only my mobile data (internet) is not working, and i didnt find any info of how to solve this problem of the baseband, i tried extracting the tar.md5 of the official rom and only flash the modem with odin, and there is no change, if somebody knows something about how to solve this.
Thanks in advance.
So i have a problem with my s3 i bought a new motherboard for it couple of days ago and i install it and everything and i put on stock rom everything is working fine atm.
But when i try to install any custom rom i tried dokdo and miui and back to n00t and all of them i get an error that it cant find my sim but on stock 4.3 it works did anyone have a problem like this if anyone knows how to fix this pls help and yes i have imei and baseband.
Was the phone running the latest bootloader and modem before you flashed a custom rom?

I was running a stock rom on a stock kernel for the modem i dont know.
Sounds to me like the bootloader and modem are too old for the custom rom. Flash the latest stock rom from Sammobile.com to ensure the modem and bootloader are matched and up-to-date.
Are you sure it is an i9300 motherboard? Not a Korean or Japanese version?
You can confirm the model number by booting into Odin mode.
Yea the motherboard is GT-I9300 so its international version
I have downloaded from sammobile and tried custom rom stillno work but when i got the motherboarc it had android 4.1.3 or 4.1.2 i dk
You confirmed the model number in Odin mode? What error are you getting in the Odin log?
There is no error it says that its custom and nothing else
The Odin log comes from the app, not the Odin screen on the phone.
On the phone's Odin screen, it says gt-i9300?
On the phone it says that its gt-i9300 but when i connect my phone to odin it dosent say anything

Why are you flashing firmware for an LDU? Is your s6 an LDU? If not then don't flash them....
Search your model number in www.updato.com to find the correct firmwares.
