[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.

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...
Sent From My GALAXY S3 I9300 via Tapatalk4
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

Thank you very much for your help I just don't want to screw up my phone I'll root tomorrow after a full charge

[Q] Galaxy S2 i9100 Official Android 4.1.2 Firmware

Does any one have the download link for Android 4.1.2 Jelly Bean (i9100) Samsung Official Firmware? I flashed a custom rom to my Galaxy s2 without creating a firmware backup so I cannot revert or downgrade to original rom. So I was wondering if I could download official 4.1.2 firmware then I can flash it. One more thing pls: A friend of mine own a galaxy s2 i9100 and it has the same version of firmware that I am looking for, so can I make a backup of its firmware and flash it to my s2 or copy its firmware as a zip file or something.

Sammobile is all you need looking for your apropiate carrier of course.
Samobile requires premium account

No it does not. You only have to register, for free, in order to DL firmwares. Nothing premium required. Stop spreading nonsense.
Also, next parrot who posts 'Go to Samfirmware' to this thread dies. Once was enough, 3 times is ridiculous. What the hell is wrong with you people ?
I thought it was premium ..
Thank u man

If you want a custom jb ROM working fine in WiFi and signal, install shostock3 v4.0 or if you want come back to stock use Odin and install the last stock firmware I777UCMD8

If you have SGH-I747 as your signature indicates, then you are in the wrong forum. If so, disregard the advice above, and go to the correct forum for your phone.

[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
