This rooted kernel is for the "rooting beginners" and those who want to keep as close to stock as possible. CF-Root takes the kernel from an original Samsung firmware, and just adds root, busybox, and ClockWorkMod (CWM4/5) recovery. For Galaxy Fit You Need To Flash Clockwork Mod Separately. The Kernel is Custom Supporting Ext4 FS, OC, UV and other Features
THIS IS NOT A ROM - it is only a modified kernel. You need to have the relevant firmware already on your device. You do NOT need to wipe anything for this patch. You DO need to read the instructions. PLEASE READ THIS ENTIRE POST!
Donate
There have now been nearly 1.000.000 downloads of CF-Root for various devices (see for example Galaxy S1, Galaxy Tab 7", and Galaxy S2), and many more if you include ROMs, kernels, etc that use it. Don't be a leech, buy me a beer (and use the "Thanks" button!). Imagine if every CF-Root user had donated me $1...

Other kernels
Replacing CF-Root with other kernels and vice-versa sometimes works, sometimes it doesn't. I don't have a list.
When going from CF-Root to another kernel, root will usually stay, while CWM will be lost (unless the other kernel also includes it), but there should not be issues. The CWM Manager app may remain, but probably won't do anything useful. For Galaxy Fit CWM Recovery Wont Go Flashing Other Kernels
CF-Root/CWM4 is NOT compatible with ROM Manager! Manage/perform your backup/restores from CWM directly or using the CWM Manager application included with CF-Root
- ADB is functional in recovery, however it may take up to a minute for it to start up after booting into recovery.
- When connected to ADB in recovery, you need to use "rootsh" command to get root, instead of "su". This will not prompt you, it will just give you root. Obviously the "rootsh" command does not work when booted normally.
CWM Manager
Because of incompatibility with ROM Manager, I wrote and included "CWM Manager". This is a new app (as of March 30, 2011). You can find it under Applications -> CWM. It is much faster to use than manually booting into CWM and selecting these options.
Features:
- Boot to CWM
- Backup firmware
- Restore backups (CF-Root v5.0: including partition selection)
- Delete backups
- Install APKs
- Flash CWM3/4/5 update.zip's
- Flash kernels (zImage, zImage in TAR, zImage in ZIP, zImage in TAR in ZIP) - without changing warning triangle status or increasing flash counter
--- without changing warning triangle status or increasing flash counter
- CF-Root v5.0: Flash complete firmwares (seperate files as well as .tar and .tar.md5 archives, dump files in /sdcard/external_sd/firmware folder)
--- without changing warning triangle status or increasing flash counter
--- can pre-root new firmwares during flash
Note: If you flash a different kernel, CWM Manager may remain installed. However, functions may not work, because they need kernel compatibility !
Custom boot / init scripts
CF-Root will execute the following scripts if present, in the order listed:
- /system/etc/init.d/* (there can be many files here, no extensions! use #!)
- /system/bin/customboot.sh (busybox sh)
- /system/xbin/customboot.sh (busybox sh)
- /data/local/customboot.sh (busybox sh)
Please make sure you chown / chmod the scripts correctly so they can be executed. Pretty much root:root / 755.
Custom boot animations and binaries
CF-Root also supports custom boot animations:
- /system/media/bootanimation.zip
- /data/local/bootanimation.zip
And custom boot binaries:
- /data/local/bootanimation.bin
Installing busybox over the included version
It is possible to install a custom busybox over CF-Root v3.0 and newer. However, this is not without risk. CF-Root makes heavy use of scripting, and many CF-Root scripts rely on the internal busybox version. If you do install a seperate busybox version (always use "stericson" installer!), install it to /system/xbin. Installing it to /system/bin will mess things up for sure. Even if you do that part right, it may still break CF-Root, so make sure to make a backup before trying.
How ?
I wrote my own toolchain to ease patching of initramfs, and that is what all this is based on. Took me a few days to get it to this state. If this works right, however, next time it will probably take me a few hours tops
