Custom Galaxy S3 Kernel ‘Zaventh’ R3 Released

This is a kernel I’ve made for the T999 to learn more about kernels and also to enable some features that I wanted. I built it on top of Romanbb’s Adama 003 kernel, so please go thank him there.

My philosophy is to build a stable kernel that is tuned for real-world performance and not benchmarks. I have been running this kernel for a while now with great success, but as usual I can’t be responsible for anything that happens to your device.

New in R3

  • SIO scheduler
  • Patched from 3.0.36 to 3.0.40
  • Insecure adbd binary (adb remount command now works)
  • Default scripts now executed before init.d scripts

  • Samsung’s proprietary exFAT modules will not work with this kernel. Make sure your SD card is FAT32 or EXT4.
  • Please don’t flash this if you don’t know exactly what you’re doing as I’m too lazy to include n00b instructions.
  • You should already be rooted and have busybox installed into /system/xbin before flashing this kernel. As always, wipe all caches after flashing.

Thanks to Romanbb for the initial kernel including OC/UV/OC hacks.
