Does that actually work with MG4 4.1.2 when I was in the thread it says clearly that it works on 4.2.2 leak...

Nothing works with 4.2 leaks as there's no kernel source for 4.2.
It works on all sammy 4.1.2 and all AOSP 4.2.2

So I can use it with the 4.2.2 paranoid android and still keep my ROM will it mess up anything with my efs since I'm on MG4 thanks for the reply

It should be fine so long as you don't flash additional basebands from within the second rom.
Sent from my GT-I9300 using Tapatalk 4

How can I tell if this will do different basebands? And is old root ok for MG4 or is there a updated root sorry for the questions I was fine before MG4 came along I haven't flashed ROMs since
Sent From My GALAXY S3 I9300 via Tapatalk4

You can only have ONE baseband on the phone. Aosp roms don't come with a baseband.
Root as before

[Q] International Compatibility

So I asked a question like three days ago and I think I wasn't very clear
I have a Mexican SG3 and I want to try one of the European Jelly Bean Roms that have been out for weeks but I haven't really understood how does the builds and basebands work on this phone, I used to have an epic 4g touch from Sprint and I was used to only have one kind of baseband because it's an us phone only, but with this one I don't know what all the XX(insert random letters here) builds mean cause my phone has a build number of UBBLG2 and I'm afraid that if I install one of the jelly bean roms my data service will be lost...could someone please tell me how does this work

since its the international s3, you have no problem.
If you lose your service flash a compatible modem/radio from here http://forum.xda-developers.com/showthread.php?t=1740061

There is only one modem for JB, much more simple than allthe ics stuff. In the pointed thread download XXDLID baseband if you don't already have it.

Don't worry, just flash the jb rom. If you encounter andyproblem, then you should flash another modem.

[Q] How do I get stock 4.1.2 back on my S3 using OSX?

HI all!
I am at a loss here. I have searched and searched for a solution to my problem but to no avail!
Basically I have flashed CM10 on my S3 and also have Clockwork Mod recovery, I would like to go back to the stock rom with touchwiz ui on top. I have found guides online on how to flash stock roms using odin but I have a Mac and do not have access to a PC. I really need some guidance with this as cm10 is annoying me at this point and I would just prefer to go back to stock/out of the box rom. P.S. I did not back up my phone when flashing cm10.
Many thanks,
Dave

Install mobile Odin, put the Rom on an sd card. Then flash with mobile Odin.

The IMEI is your device's fingerprint number, flashing roms don't change it, unless the rom file is corrupted or some error happens during the flash, what is kind of rare.
You should be able to flash without problems, but don't forget to flash the correct rom version for your device, and to flash GAPPS after flashing the rom.
Hey
In addition I would strongly recommend to back up ur efs..

that's actually downgrading rather than upgrading. 4.1.2 builds are newer and use a new EFS format but the 4.2.2 builds are older and use older EFS format! so back up your EFS every time before you flash something as already mentioned above. if you face any problems refer to the link under my signature and post there for any queries.

my friend has a galaxy s3 with android 4.3 and knocx bootloader how to install custom recovery and rom on it in my dads s3 with android 4.1.2 was easy help me to install custom rom it runs XXUGNA8 Android 4.3 version
The i9300 doesn't have knox. Either you are mistaken or have another model, in which case you've posted in the wrong forum.

[Q] help? I can't find out my stock firmware

Hello I own a Samsung galaxy SIII GT i9300 running nightly build PAC man ROM 4.4.4. I deleted my stock backup on cwm thinking that I wouldn't need it but I'm getting a upgrade to the LTE version (GT i9305) now and I can't find out which model I am for stock firmware to sell this on, it doesn't say in settings and dialer doesn't work, and I need stock to sell this on. Is there a working ROM on all international's? I'm a noob at this so sorry if this is already answered or its a stupid question
EDIT:I know how to go to stock but don't know which firmware is right. also build number in settings says PAC man ROM nightly then numbers..
Thanks in advance!

Follow the guide in sticky thread, download the latest stock firmware for your country at sammobile.com
It doesn't matter what version your original firmware was, just make sure it is for the i9300.
Everyone says it does but okay thanks if it works
