back-to-n00t; Bring the LTE fun back to 3G


/* Introduction */

Previously, Korean developers were porting i9300 ROMs to e210s.
How ironic, we are now porting e210s ROM back to i9300!

The Korean letter "눝", pronounced "noot", symbolizes LTE(as you can see).

/* Overview */

Touchwiz Android 4.4.4 for Exynos Galaxy S3 3G
Ported from Exynos Galaxy S3 LTE
Havily debloated
De-KNOXed
Deodexed, zipaligned, uncompressed
Since this no longer bases on N7100 ROM, this is much more stable than other KitKat ports

/* Disclaimer */

Your warranty is now void.
I am not responsible for bricked devices, dead SD cards,
thermonuclear war, or you getting fired because the alarm app failed. Please
do some research if you have any concerns about features included in this ROM
before flashing it! YOU are choosing to make these modifications, and if
you point the finger at me for messing up your device, I will laugh at you. Hard. A lot.

/* More disclaimer */

Unlike Besonderes, everyone is encouraged to fork this project and make his or her own ROM based on this project.
Please read https://github.com/arter97/back-to-n.../master/README

/* Supported device */

Galaxy S3 3G International (GT-I9300)
Galaxy S3 SK-3G (SHW-M440S)

/* What you need to know */

'Open' does not mean 'no-respect'
Leave credits to original developers

Config optimizations
Unaligned access enabled
Deadline I/O scheduler with latency improved

MMC and ext4 performance improved
ARCH_POWER enabled
New ARM instructions set

for the last few days i have tried to help you guys with some problems , so that you can use this rom as a daily driver .
So @arter97 and me had a little chat over twitter , where he agreed to give you guys a new build with all the bug fixes and improvements , and after giving you the new build he will mark this thread as finished that is no more development can take place after the v7 , So after this build i should see none of you complaining as i run this rom with all the fixes integrated and it is flawless . So do not bother arter97 after he releases this new build , yes if you have some question you can ask me , will most probably solve it for you , because i have been using this rom for a long time and i myself have solved most of the issues i used to get . Get ready and dont ask for ETA's he will give you the new build or i should say the final build and then he is done with this project . Thank you i hope you Co-operate !!

Hello , @arter97 So i will link all those fixes that you might want to integrate . Also i will be posting a link for the CSC , may be you can replace this very CSC wit the one in the ROM , this helps with the 2g /3g toggle in settings , may be you can link my post for the step by step instructions to get 2g /3g toggle in the settings "http://forum.xda-developers.com/show...postcount=2423" that will help users , also may be you can edit the OP saying that this firmware can now be used with other kernels that support this rom as i used ARCHI KERNEL AND BOEFFLA and both worked fine . so here are the links to the fixes .
New CSC :- http://d-h.st/7KI
Telephony fix :-http://forum.xda-developers.com/atta...0&d=1420370418 that enables 2g/3g toggle to work by my step by step instructions whose link i posted above , having that on O.P will prevent the users from asking the same question again and again .
JustArchi's camera fix :-http://vk.com/doc10926468_344278240?...9b9bd6b15b14d3, my camera was not working when i flashed the rom so did the cameras of many users . integrating it will fix camera for evryone.
Also the BLUETOOTH FIX that you were talking about :-https://mega.co.nz/#!F9NyEayT!HYelXB...tje08IlfFE6dMM
I think that is all , these three are the issues that users complained about. And yeah thanks @arter97 for your great work.
