[17.12.2011][CF-Root v5.1] ICL53F - su+bb

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 firmware, and just adds root and busybox. 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 THE ENTIRE FIRST FEW POSTS! 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... Main features - The kernel is fully stock and taken from the original firmware, with just the following added: - Superuser v3 - Busybox v1.19 - Custom boot / init scripts - Insecure Installation instructions Please see the next post ! Recovery Unlike CF-Root for various other devices, CF-Root for the Galaxy Nexus does not include any recovery, due to kernel and recovery being separate partitions on the device. This means you don't need to flash a recovery with your kernel. 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/sh") - /system/bin/customboot.sh - /system/xbin/customboot.sh - /data/local/customboot.sh Please make sure you chown / chmod the scripts correctly so they can be executed. Pretty much root:root / 755. Busybox Busybox by default creates symlinks in /sbin. You can turn this off by executing the following: adb shell setprop persist.busybox.nosymlink 1 And reboot your device. Installing busybox over the included version It is possible to install a custom busybox over CF-Root. 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. It is now used to make CF-Root for many devices! Help! Which file do I use ? Check Settings -> About phone -> Build number and find the matching download. YAKJU downloads are for GSM, MYSID downloads are for LTE. Download These are general-purpose downloads. See the posts following this one for the kernels. source
