Plus search exact same question posted multiple times .
XDA Chef Central .
But you would be best in my umble opinion to mess about and change an existing custom rom yourself to get an idea of what is required as a first step .
Basics are Cut and Paste .

I'm a developer, and since I bought my Samsung S3, I wanted to create a custom rom. I'm motivated.

[Q] Intern Counter and Custom Rom Questions

Hi guys ^^
Just got two questions which bother me ...
1. Anything new about that internal counter? ... Read about the secound counter in the S3 before ... one which can be reset by USB JIG and one which is really hard to get to. Is there are a opinion to resett it at the moment?
2. Secound Question is pretty nooby I know but ...
Which are the leading Custom Roms right now? Yeah I know depends to the user etc ... but there are always very famous and good ones like on the S2 it has been Checkrom v7 ... Cynag ... etc
How is the development at the S3 right now? and what are the main advantages at the moment of the custom roms. :angel:
To reset the flash counter use triangle away the development for s3 is very good loads of Roms.
And I personally can't comment on Roms just try them all see which is best for you.

[Q] Don't kill me for asking

Good day, everybody!
I've seen that there are here many great experts in this domain, so that I would like, with your permission, to ask why SG S3 has to be factory unlocked before rooting? All the guides provided on pages I've found on internet specify that (as a newbie, I only can assume that factory locked means that the device is working only on a specific mobile carrier, which is applicable in my case).
I also want to get a newer stock version of Android, and I dont't know if the latest is 4.1.2 or 4.2; maybe you can tell me.
From what I've read, in order to do so, I firstly have to root my phone, using a method for the specific kernel I have (XXDLJ4), and then install the software, using clockworkmod and the stock Android kitt. If I've understood it completly wrong, please let me know.
I can figure that you have been hearing this kind of questions over and over in your life, and I understand you perfectly, but I wouldn't be coming here I didn't you're the best.
The AP of my device is 9300XXDLJ4 with CP I9300BVDLI1.
Many thanks for your patience and time,
Cristi

Which means that I only can install 4.1.2? If so, which is the name of it? Does it have be "compatible" with my device?
I forgot to mention that my build number is JRO03C.I9300XXDLJ4.

Sounds like the unlock you used wasn't a permanent one, find your carrier Rom and flash that with Odin.....then get a proper/permanent unlock code

AS you post above shows lack of basic knowledge .
Please read the basics before flashing all stickied faqs and guides .
Is it worth it your choice suggest you actually take time to read the rom thread and decide .

JJEgan is being like that because this has been asked multiple times... now if you just search around the forums especially the Stock Firmware thread you'll find your answer.

ok i will
thanks for your relpy !!!
I've been using the 4.3 Wanam version with Yank custom kernel, as the official version IMO is not production quality yet.
If you just want a normal upgrade through OTA or Kies, my advice would be to wait as the current 4.1.2 stock firmware is very solid.

You lack basic knowledge and therefore in greater risk of bricking your phone .
If you are a experienced flasher you should know better than to ignore the basics .
Your choice your brick .

[Q] Are Custom Roms Region Specific??

As far as i understand flashing stock roms meant for a different region than mine(India/INU, in my case) will cause problems(soft brick)..Now, my question is, what about custom Roms?? Are they meant for specific regions?? Can i flash any custom rom made for GT I 9300 ?? Or have i missed something??

Nope. You can flash any region stock firmware/rom. My phone came with a France region and I have a UK firmware on it. Just make sure the model number is the same. GT-I9300 for me, think yours too.

You have no right to ask me to shut up for speaking my free mind because pasting threads over and over again flooding posts after posts like a vigilante towards the threads that leads to many pages which you could have just ended it by one short simple answer. Besides, you do know that sometimes the search function is not 100% noob proof. If you're sick of the op above don't reply let others do it. It's Q&A. Nobody points a gun at you to start replying every noobs that exist in the world with your copying and pasting skills inserted together with rude remarks. Likewise you're free to report me if you like. Otherwise shut up and let me speak my mind. Good copying and pasting skills of yours is contributing a lot in here.
