I am not responsible for anything you do with your device. Anything you or someone else flashes or modifies on your device or someone else's device is not my fault or responsibility to fix (or break).

What is this?
SGH-M919V_JB_Opensource.zip [MDB Version] compiled with the defconfig grabbed from May 7th OTA - M919UVUAMDL. You can grab the source like I did, from opensource.samsung.com. Defconfig was the only change, since CONFIG_SEC_RESTRICT_SETUID was already commented out from the source linked previously. Modules are also included from this kernel source, same link as previously as well.
Flash this if you want to have a non-SetUID restricted kernel compatible with the May 7th OTA - M919UVUAMDL and you don't want to flash the old boot.img which is done in my root thread.

Downloads
Mirror 1 - Dev-Host
Mirror 2 - Batakang

Source
Github

Instructions
  1. Flash in the Custom Recovery of your choice.
  2. If you aren't already rooted, flash a Root.zip such as SuperuSu by Chainfire or Superuser by Koush.
  3. Reboot and enjoy.

Tested On
  • M919UVUAMDB
  • M919UVUAMDL

Be Advised
SDCard's using exFat will not work with this kernel.
Flasher updated, now will not remove all modules in system, but will just overwrite the ones made by Samsung Open Source. This way you don't need to flash exFat modules separately. You can still do so if you want.
The exFat kernel module is not open source and thus is not included in this. You can flash this to get exFat working if it is not..


Screenshots


Thanks to Shabbypenguin for advice on defconfig and modules. Hope this helps someone, and if it did, use the Thanks button.

Haven't tested on original firmware, only the OTA. Would be nice to have someone try it out and see.

EDIT: Original firmware now tested.

This is greek to me.

I know you're busy. But could you explain the advantage of having a "non-SetUID restricted kernel" and "don't want to flash the old boot.img"?

"non-SetUID restricted kernel"
Being able to have root on the latest firmware.

"don't want to flash the old boot.img"
You can already root the latest firmware by running the ORIGINAL kernel that came with the phone.

Also, just updated OP tested on original firmware.

It's already overclocked to 1.9 Ghz... I wouldn't be one to push it further.
