[ requirements ]
latest FreeXperia Project CM7 ROM (available from here: http://forum.xda-developers.com/showthread.php?t=1128216)
bootloader unlocked
working fastboot
u have read this: [How-To] Safely test custom kernels / custom ROMs and get back to stock SE 2.3 ROM
android app for overclocking like SetCPU (paid) or NoFrills CPU Control (free) OR use CPU Setting under CyanogenMod Settings (Performance)
NoFrills CPU Control (free) to select I/O scheduler
VDD control app: IncrediControl
[OPTIONAL] CIFS Manager (free)
[OPTIONAL] Swapper 2 (free)
[OPTIONAL] xCharge Reboot Otions (paid) [app to reboot into recovery/fastboot mode]
[ how to install ]
download the boot.img
save the boot.img in the folder with fastboot binaries (fastboot.exe files)
power down device
start device in fastboot mode
use the following command to flash the boot.img
Code:
fastboot flash boot boot.img
reboot phone and enjoy the kernel
FOR OVERCLOCKING
start SetCPU/NoFrills CPU Control app on ur phone (or any other app which supports overclocking) (u may get a popup asking for SuperUser permissions, click ok/yes/allow)
now slowly increase the MAX slider to the right (one notch at a time) to increase the maximum frequency limit
DO NOT JUMP TO THE LAST POSSIBLE FREQUENCY
SLOWLY increase the frequency one notch at a time and do stability/testing for few hours

Finally!!!! Nice Doom!

Awesome work Doom! I'll give it a flash now

---

here's a noob question ><, can I flash CM7 to use the CWM backup from my stock rom? It's compatible right?
And CM7 is rooted by default right?

You can still try it, but I guess there's no guarantee it will restore to CM7 correctly. It depends on what kernel/firmware you come from and how similar they are to CM7. Can always just try it and see if it works

Hi Doom,
This Kernel can be work's with the XMIUI Roms??

---

Titanium Backup does the job. It was the first Android app I paid for, and it's never let me down.

thanks for the info, I am not sure whether i wanna pay for the full version though, is the free version able to do batch backup/restore?
cause don't really want to backup/restore one by one

use any kernel which has CWM recovery, enter into recovery and take nandroid backup... then install the kernel required for the rom u want to use and then flash the rom...

In the requirements section you link to the cm7 arc rom, not the play rom. correct link is this one: http://forum.xda-developers.com/showthread.php?t=1128216

nice catch
i just copied my ARC thread contents
will correct it now

---

i can confirm that the kernel is fully! working with the nightly build of cyanogenmod

---

Hey, in case no one else has checked, the kernel boots beautifully on the CDMA play, however the hardware buttons below the screen do not work. Overclocking works, camera does not work, wifi works, calls work, data works.

hey doom great work on this evrything is working for me except bluetooth doesnt turn on at all

Also getting this.
Used the 'original' FXP kernel before, though i haven't attempted to use BT there.
