Need help regarding 4.1.2 update

I'm new on this forum and I'm from India.. Recently I got one AT&T S3 i747 unlocked version for my dad and it's running with the 4.1.1 version..
While trying to update through OTA it shows there's no update and I would like to update to the 4.1.2 version...
Could someone tell me how to update to 4.1.2 manually and will there be any problem with the network since I'm from India.. Coz all the 4.1.2 roms in Samsung updates website are for Canada or US

anybody with a solution??

I found this here and it should help get you to 4.1.2 http://forum.xda-developers.com/showthread.php?t=2388065 I believe you need to be already rooted with a custom recovery on 4.1.1 and then from there you can flash the .zip but factory wipe and backup before hand. I also don't think you need to download the modem from there just the 4.1.2 ROM

I used it on mine just fine.

I'm running cm10.2 stable right now with T999LUVAMB7 baseband (android 4.1.2), however I want to flash cm11, do I need to flash android 4.3 baseband. And if I did flash the baseband, would this cause a problem to my imei number as I've seen many reports regarding imei being erased when flashing. Please share your knowledge, thanks.

[Q] Will my 4.3 work with 4.1.1 baseband? SGH-T99?

The title explains my question, will sombody tell me the answer?
i updated my s3 (SGH-T999) to 4.3 without sim unlocking and now the i downgrade i keep loosing imei (null / null) :crying:
I did a backup of my EFS on 4.3 and tryed restoring it on 4.1.2 and 4.1.1 and it just didnt work
i heard on a thread that if you are on 4.1.2 and want to sim unlock your device you dont have to downgrade firmware to 4.1.1 you'll just have to downgrade the baseband thank you for your atention i hope to see an answer soon

It won't, and if I'm not mistaken the unlock method won't work at all if you do the official 4.3 update, even if you downgrade basebands

[Q] Canadian Stock ROM Compatibility with ATT Variant

hello everyone,
I am tempted to flash the stock ROM package for the SGH-i317M on an ATT version of the device, the SGH-i317
the reason I want to do this is because of theATT KK update, and how it locks the bootloader.
the ATT note 2 is now on 4.1.2 (MA4), so its still on the old bootloader..
would I be able to get away with this, or will I nuke my phone?

I have the ATT version of 4.4.2 (NE5) available without the bootloader. Follow my sig or check the dev section. @dicksteele also has a modded and debloated version out.
