This is still in beta! If you know how to flash with Odin, please help test so all bugs can be found and fixed to allow for wider release!
What is this?
Another lagfix. This one is a bit different from existing lagfixes though:
- Differences from OCLF: Uses native EXT/JFS instead of loopback mounts. Loopback mounts in linux can be a bit flakey at times, especially when they're on RFS. So this is generally better.
- Differences from lagfix kernels such as voodoo or sztupy's: These types of lagfixes are kernels compiled from GPL sources for specific devices. This can cause a number of issues, such as losing out on bug fixes in later Samsung kernels released after the GPL code, or differences in devices such as the I9000B, etc. z4mod also has (imo) a nicer design, in that it uses /etc/fstab for filesystem mounting, as well as keeping the convert scripts outside the kernel. It should also work across ALL (or many?) Samsung devices without changes!
How do I use this?
Install the app. Click the buttons. It should all just work. Let me know of any issues or complications! This is still in testing!

Any custom firmware that uses a stock kernel works as the stock kernel in the table above
Custom kernels that make use of changed filesystems or boot up scripts are unlikely to work at this time. Emphasis is on stock kernels currently.
BLN (backlight notification) custom kernel for GT-I9000 works
Voodoo kernels do not work
Kernels with heavily modified boot procedures such as rooted Vibrant kernels do not work
CFRoot kernel does not work.
DamianGto's kernels work
