[APP] z4mod by RyanZA (lagfix)

[ZowLe]

Alright, here is the z4mod app at long last! This release needs a lot of testing for different devices still, so make sure you check the compatibility table below unless you know how to use Odin to flash back your original kernel. Thanks for helping to test this!

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!

Custom Firmwares
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.

Custom Kernels

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

Other Samsung Devices
