THIS IS ONLY FOR USERS ON MF1 OR EARLIER BOOTLOADER WITH CUSTOM RECOVERY (cwm or twrp)

THIS WILL NOT AFFECT BOOTLOADER OR MODEM AS THEY ARE NOT INCLUDED.

GENERAL DISCLAIMER : YOU ARE RESPONSIBLE FOR WHAT YOU DO TO YOUR PHONE!

This is a stock, rooted TW 4.3 rom based off of the recent ML1 update. It does not contain a bootloader or modem. KNOX has been NIXED too. ThePagel was able to grab the .tar which made this possible. Go throw a huge thanks his way. Also send some thanks to decimalman for allowing me to use his kernel. As a few others have figured out, the stock kernel doesn't play well with the earlier .TZ firmware causing wifi to be borked. You can check out decimalman's work here. Remember to thank him while your there.

More about the firmware now. DON'T JACK WITH IT!!!!! I know in the past it was common practice to flash the newest firmware along with whatever rom base you were upgrading to but as Invisiblek "discretely" informed us here, that is no longer the case. You will brick your phone if you try! While your reading invisiblek's thread, go ahead and grab the new modem. You'll be glad you did.

Ok, back to the rom. I was doing this blindly as my S3 is on vacation with my son at the moment so I owe a huge thanks to jlyle and prdog1 for testing it out for me. Give them credit for the kernel find that fixed wifi.

Decimalman goes out of his way to support Trickster MOD which is available in the Play Store but states most other tuning apps work well.

decimalman's TW4.3 dkp kernel
Pre-Rooted
Deodexed
Zipaligned

When booting for the first time, it may take up to 5 minutes. DON'T PANIC!
