Instructions:

How to Lock and Unlock the Bootloader : Thread by Spyder-X with Instructions

Please make sure to delete the following modules if present in /system/lib/modules/ this is really important otherwise phone might reboot due to unloading adresses have changed : delete x8oc.ko, x8uv.ko, cyctma300_ser.ko, x8mddi.ko, ext3/4.ko jbd(2).ko or mt.ko

except OC everything is already in Kernel, please do not try to insmod current x8oc/uv module needs to be recompiled with new addresses

unpack the Kernel zip and place ftf file in firmware folder of flashtool

select flash and choose ZombiePanic

flash like usual

Features

no touchbug with GB roms

Tun/Tap

Overclocking (and undervolted)

built in Multitouch

mddi patched!

netfilter

iptables/xtables

ASHMEM/PMEM/SHMEM

EXT3/4 JBD(2)

USB RNDIS/RMNET (one step closer to native USB Tethering)

partial USB Host Side (not yet fully working)

alot more filesystems supported (CIFS,CD_ROM ISO,etc.)

few performance tweaks on performance govenor, smartass would be nicer maybe next time after i get permission

Bugs

none known so far

Download

Again you do this at your own risk!

Download ZombiePanic Kernel v1.63

At the Moment I advise to not use Overclocking as I still need to patch some PLL values which means OC maybe slower than set to 600 MHz

Download Zombie Panic Extreme Edition

Warning: Do not use if you are a regular user, its for hardcore overclockers. Zombie Panic Extreme Overclocking Edition be careful with Overclocking!

Features:

- upto 864 MHz with patched PLL

- features (and maybe bugs) from ZPKernel v1.61 integrated .

might be unstable with higher frequencies!! be careful do not set cpu speed on boot while checking frequencies

I am not responsible for bricked devices. Do at your own risk.
