[T-Mobile, Samsung Galaxy SIII] cobraboy85:
Welcome to Lightning ROM

MAJOR UPDATE, REV3, CHANG LOG IN SECOND POST**********

The goal when creating this today has been simple. Squeezing the most performance out of the T-Mobile Galaxy S III as I possibly could, without destroying your battery. This ROM was build with two things in mind - optimization and speed. Nuff said. It is based off the official Jelly Bean leak as of late last night and wild child's deodexed version he was kind enough to throw down. It will probably impregnate you, with twins, then not pay you child support. If you are ready to propel your device to levels above 9 thousand, you should probably keep reading. You have been warned. IT IS FAST! ..... yet... friendly...

Like myself, in the spirit of android, I am sure you all love customization. I am doing something a little different with this. Rather than add all the toggles, mods, themes, etc, I focused today on the performance aspect and will leave the theming up to you, and after you get it set up the way you want (as there will soon be and already is tons of pretty extras for this build) revert to post 2 of this thread for a nice little guide to odex this bad boy straight from Android UI via terminal emulator. I'll take care of the tweaking, you theme it the way you want, then wrap it up with some memory optimization of your own, or don't. Sound good? Thought so ;)

Getting right down to it - a quick list of things modified here, and I know I am missing some things:

-Init.d support

-Busybox

-Deodexed (until you odex - see post 2)

-Rooted - duh

-CIQ removed***

-Debloated: removed a lot of stuff, but it is all avail' in the market, youtube, etc, you would have had to update it anyways -__-

-File system and SD read optimized for speed

-added freeza's custom CPU script to init.d ***see changelog in post 2

-Build.prop has been modified.

*added the 0 ring delay script

*wifi scan adjusted to 600

*media streaming optimized

*media recording optimized (video and image)

*data speeds optimized

-Database df on each boot / sql support - totally kanged this from somewhere else it was kanged... all credits due

-Memory optimizations

-Default IO scheduler optimized for flash-type disks (android devices)

-Carefully modified CPU parameters with performance in mind. Tweaked values to optimize IO throughput during heavy workload and multi-tasking, yet on the other end, CPU cycles are greatly reduced when system is not under heavy load. You will see this in performance :highfive:

INSTALLATION - follow this to the T, or I will ignore you. And keep in mind you might still have issues. Not every device is the same.

1. download ROM, put it on your external SD card, and verify it is good with an MD5 check

2. once all is well, boot to recovery

3. do a factory reset/data wipe (I have always been in the habit of being thorough and formatting anything 3 times)

4. format/wipe system (3 times recommended)

5. flash ROM

6. reboot (it will take a couple minutes)

7. once the device boots, let it stand alone for about a minute or so (i typically wait until it shuts off the display on its own) and ENJOY

NOTE: DO NOT TRY TO SIGN IN TO DROP BOX. I REMOVED IT. DL FROM MARKET!!

Also, some other things removed: browser, YouTube, calculator, some other stuff. I didn't remove anything that was not available in the play store. Wanted to keep it light weight. Do not try to sign in to anything other than your google account when you boot. Again, enjoy.

thanks to wild child, freeza, virus, steelH, dj, luke, ktoonz, and many others. mad respect to you all. i have implemented things that are either your direct work or things i have learned from you. so here is my humble shout out. if there is something i left out, somebody i didn't mention, please forgive me and post in this thread and call me out, i will happily update the OP with thanks. respect to you all

REV_3 - ready, set.. ok click now!

With morfic's kernel..... clocked at 1.83
