#25 Custom Rom by "Doc Froyo v2.2 XXJPO v7.6.2 (6/11/10)"

Simple steps you can follow and upgrade your phone to the latest stable JPO release.

1 - Get the stock ROM of I9000XWJM8 first on your piece with RE-Partition and 512.pit with ODIN v1.3.

3 - Perform a factory settings restore, and after that setup phone language, location, disable automatic sync.

4 - Install CF-Root-XX_XEU_JPO-v1.2-Busybox-1.17.1.zip via ODIN. It's a much simpler root (to use) than the other methods available, just a single PDA flash through ODIN is all there is to it.

This kernel has:

- Based on JPM Froyo kernel and modules from XXJPO initramfs
- Works on all stock Froyo ROMs XXJPO/XWJPA and popular custom ROMs
- 341MB RAM and all features should work e.g. 720P recording & playback
- Includes sztupy's Universal Lagfix
- Includes neldar's BackLightNotification 2.2 from https://github.com/project-voodoo/ba...ernel_patches/
- Sharpness & color fix for UI, inspired by supercurio's work on Voodoo
- SpeedMod: Replaced kernel jhash2 with jhash3
- Includes my Startup Tweaks from http://forum.xda-developers.com/showthread.php?t=813309
- Adjusted kernel HZ value to (hopefully) balance battery life & smoothness
- Uses BFQ IO scheduler by default, from http://algo.ing.unimo.it/people/paol...ed/sources.php
- Updated ext4 code in kernel from http://www2.kernel.org/pub/linux/ker.../ext4-patches/
- Optimized compiler flags: -mcpu=cortex-a8 -mfpu=neon -mfloat-abi=hard -fno-gcse -fprefetch-loop-arrays --param l2-cache-size=512 --param l1-cache-size=64 --param simultaneous-prefetches=6 --param prefetch-latency=400 --param l1-cache-line-size=64

This kernel is based on sztupy's Universal Lagfix: Lagfix and root options are accessible by booting into the Recovery Menu. More instructions on other ULF settings are here: http://forum.xda-developers.com/showthread.php?t=814228

To get the best speed, it is recommended that you enable all Tweaks from the Recovery Menu. Tweaks are under ULK features. Info on Tweaks: http://forum.xda-developers.com/showthread.php?t=813309

In my case i use the below Lagfix mode and most of the Tweaks enabled.

No-RFS Overkill: turns on all options: everything is ext4+ext2 and /data/data is bound to /dbdata 
(If using the overkill scheme using the bind option is dangerous if using too much apps, so I disabled it in the advanced menu.) 

Screenshots will follow on the next post.
