Complete Guide how to use Custom Kernel - XPERIA X10 Android Development

This guide (A-Z) for most custom roms for x10 out there how to use custom kernel.
-Just skip to step 10 if you already have the Custom Rom flashed.
++REMINDER++ please don't install custom kernel provided by the ROMs modders just yet, or you will end up stucked at Bootloops.
Thanks to J, Z, Goroh, DL, AZ, AD, WB, AJ and all of you!!
1 - Flash your X10 with fresh SE Firmwares using Flashtool, Reboot, wait until you got stable signal. Turn on USB debugging.
2 - Root your phone using Flashtool, Install Busybox included in Flashtool.
3 - Reboot you phone. Now go to your phone screen, search for Busybox icon. open Busybox, press install.
4 - Download xRecovery 0.3, place it in your SD card.
5 - Open your file manager and search for xRecovery that you just downloaded. Install xRecovery
6 - Download your Preferred Baseband (i'm using .54 in this Guide)
7 - Flash your new Baseband using FlashTool. Reboot, wait until you got stable signal
8 - Download your Preferred custom Rom (Achotjan_2.2.3_v06 & Wolftweak ROM V009) this guide should work for all custom roms. Place it in your SD card.
9 - Reboot, now go to your xRecovery. Flash the new custom rom.
10 - Download Goroh custom Kernel 362 & DoomLord custom Kernel v02 boot.img & wifi module (X-Series for me)
11 - Reboot, go to your xRecovery and flash Goroh custom Kernel 362 FIRST!. Reboot, wait until you got stable signal
12 - Install setCPU, open. Set your setCPU Max: 1113600 Min: 128000 (Higher might get WLOD)
13 - Reboot, open your xRecovery again and flash the latest kernel from DoomLord v02 X-series boot.img & wifi module
14 - Reboot, enjoy the latest custom kernel!
15 - You know what, Your just F****D SE in the AZZ... xD
S-series - Stock like - will be using stock SE kernel voltages, so should work on most devices w/o issues
X-series - eXtreme - will be undervolted, so as to give better battery life
This is what i did, and it's working Perfectly on AJ & WB Rom
No Negative Comment Please.

the first 9 steps arent required actually
they are only useful if u want to do a CLEAN install of everything...

QUESTIONS
a. After rooting the phone, do you have launch Busybox? I though it was already installed and functional as part of the root process (Flashtool seems to think so)?
b. Why go through the process of downloading xRecovery and installing it manually, when you can install it directly through FlashTool?
c. At what point (if any) once you're in xRecovery should you be wiping things like phone cache, Dalvik cache, and battery stats?
d. If this is to be a general guide, you may want to mention that SetCPU is really an option, and not a required part of the process.

a. you´re right
b. you´re right
c. not extremely necessary if you follow the instructions (flash from scratch) but always advisable when change between roms. always right before the installation of the new rom
d. not necessary at all BUT the OP advise the Doom kernel witch is by default on 2(and something) and 9(and something) locked. to have 1.. & 1000...you must have setCPU or another

[*]now for sake of safe booting i have hardcoded the startup/bootup frequencies to min:245, max:998 (in ramdisk) u can over-ride that using setcpu, ('set at boot' option should be used only after u have done adequate testing)

either way, simple & good guide

Great guide, I no longer get random reboots but i cant get wifi to work..
says Wifi error? i have tried with both X & S-series installing both boot.img and wifi together then rebooting but still no luck
ROM:FreeXperia Achotjan Froyo 2.2.3
Baseband: .54
RESOLVED.
Started from scratch and used
zkernel_0507_modDK_v02-X (X-series)
Boot.img (Froyo)
and
Wifi module
Then I had to re-enter wifi password once wifi was working again.

Cool.
One more question:
Is it sufficient to make an xRecovery backup of the stock ROM after installing and rooting it, and then restoring that to create a "fresh install" of a new ROM, or is there something that isn't done by restoring that makes doing it all from scratch a better option?
Just wondering so I can potentially save some time for future ROM installs.

it's not really necessary because, you can always flash it with SE Firmware with fresh stock rom.
