Hello guys,
Ive bought a samsung galaxy s III(gt-i9300) from ebay. Its from swisscom mobile but i am using it here in india with my vodafone sim. Now im clearly new to this and was havig a million questions.
CAN I USE THE ROMS and MODS of the general galaxy s3 for this phone ????
If it's a genuine i9300 then yes, all i9300 firmware will work.
Don't ask questions that have already been asked a thousand times, go read the general forum, stickies. They will answer all your questions and show you how to safely customise your phone.
Backup your efs folder before you change anything.

Hi guys , i need your important help.I have Samsung Galaxy S3 (i9300) ''Live Demo'' (It's a promo code).It works great but GSM is locked for every operator.
I almost rooted and i flashed OMEGA custom rom from xda.How i unlock gsm ???
Does it have an IMEI? If so you should be able to purchase one of of ebay. If they aren't available yet, they will be soon.
Edit: By "purchase one" I meant an unlock code...if you have an IMEI.
It works for every operator ?
You mean something like that cellunlocker service ?
I have an IMEI but the device its only for promo..doesn't read any network simcard.
So, this unlocker it works for every operator.Is anyway to rooted or flash custom ROM to unlock GSM function ?

Moving to Q&A
u could try to flash a stock rom wich is completly unlocked

it may solve ur problem
@ OP
Have you found a solution or?
Phone is an S3 for T mobile running 4.1.1
I've been in phone unlocking hell for 4 days.
Closely followed the "free" unlocking in debug mode method-trouble was phone will auto lock back after a couple hours or calls.
Tried turning the flag on and off, factory reset, all kinds of stuff and still no luck.
I broke down and bought an unlock code but can't get my phone to prompt for it.

Hi all ,
i bought s3 i9300 it was a european model with region lock my sim in egypt worked on it , i tried to flash another stock rom after that my sim didn't work and if i try to make any call it tells me not registered on network i tried many apps root every thing on internet that didn't work , i gave it to a guy who used z3x samsung tool and some boxes and cables and he couldn't lock it on 4.1.2 so he downgraded it to ICS 4.0.4 and he managed to make my sim work , is there any way to get back to 4.1.2 and make this network problem go away ? thanks in advance .
Unlikely, if it is network (not region) locked then 4.1 and later will cause it to lock again.
Without the genuine unlock code from the original network you cannot unlock at present, 4.0 will cause SDS to your emmc chip.
Most network registration issues at the moment are caused by people not reading about the efs change, before flashing to EMG rom. This might be your problem as well, read sticky thread in general forum: efs 'know this stuff'.
