Default [OCKERNEL - PATCHED/OPTIMIZED DRIVERS] EternityProject Kernel for LG Optimus 2x P990

Welcome to the EternityProject Optimus2x Kernel Thread!


What is it?
It is a kernel with some updates on Tegra2 and Cortex A9 management drivers.

Why should I flash it?
You should flash it only if you know what are you doing.
If you know what are you doing, you shouldn't ask this question.

Flashing methods:
1. Copy boot-new.img in /sdcard, then on your phone's root terminal type:
Code:
dd if=/dev/zero of=/dev/mmcblk0p5
dd if=/sdcard/boot-new.img of=/dev/mmcblk0p5
OR

2. Copy boot-new.img into your nvflash folder and do this:
Code:
nvflash --bl fastboot.bin --download 10 boot-new.img
OR

3. Download the update.zip version and flash it through ClockWorkMod Recovery.

Installing wireless.ko (Only for methods 1 and 2):
Code:
adb shell mount -o remount,rw /dev/block/mmcblk0p1 /system
adb push wireless.ko /system/lib/modules/
adb shell chmod 777 /system/lib/modules/wireless.ko
Features:
-- EXT4 Partition support
-- Stock frequencies
-- Optimized/Modified Tegra 2 Drivers
-- Modified Cortex-A9 (Tegra 2 core)'s cache behavior. Great results on tests.

MegaUpload says to me: The file you are trying to access is temporarily unavailable. Please try again later.

EDIT: Sorry, I'm impatient, it's all right. I'm trying .. Thanks.

It is common. I've uploaded it like 2 minutes ago, let MU process it

Quick advice: Refresh the page every 10 secs
