[CWM/KERNEL]Stock Kernel with ClockworkMod[4.0.2.A.0.42] - Xperia Play Android Development

Credits:
- DooMLord -> his recovery sources on github, and his guidance on assisting me with setting up the build environment and for his kernel.sin unpacker.
- Sony Ericsson -> the kernel with this.
I wanted the stock kernel because of battery drain issues present in many custom kernels, mine included, because although I used the semc sources to compile my kernel, it still had worse battery drain than stock.
I have unpacked the zImage from the kernel.sin in the 4.0.2.A.0.42 and then made that and a modified ramdisk into a boot.img, which you can flash.
This is for people who want to stay with the stock kernel, but want clockworkmod recovery.
Kernel string version:
Code:
2.6.32.9-perf

MD5: 1ad7e6db6258b73555f0e6ae73fe4fd6
To flash, use the command:
Code:
fastboot flash boot boot.img
If you are on linux:
Code:
./fastboot -i 0x0fce flash boot boot.img
Don't forget to say thanks if you use this!

Super interested in this since I went back to Stock rom moments ago so I can play FIFA 12. Will this work with the new HK 4.0.2.A.0.58 rom released as I have just put that on.

Yes, .42 and .58 use the same kernel.

Will this provide root? I only install Doom's for root & recovery, so if this does I'll use this instead. Thanks.

No root, but you can flash RootXperia.zip in clockworkmod (search it on google: rootxperia.zip).

Done but having booted after installing and rebooted into recovery (which worked) then restarted to phone it wont boot. Black screen after Sony Logo.
Update: Boots after 15 minutes no battery but now android market is keep coming up unsuccessful
Update 2: It just will not boot so I had no choice but to flashtool 4.0.2.a.0.58 back to default. :-(

Doesn't work at all for me - fastbooted it left it for a bit
came back and got the red blinking light.
What is the trick to get a stock kernel.sin to a working boot.img ? (Spent most of this afternoon failing to get it to work). All I really want is ro.secure=0 (or ro.debuggable=1). fastbooting CWM is ok for me.

Small how-to for creating insecure kernel
1) Unpack kernel.sin to get zImage and ramdisk (tools posted in my other thread)
2) unpack ramdisk
3) edit default.prop and set ro.secure=0 & ro.debuggable=1 then save file
4) repack ramdisk (cpio.gz)
5) repack into boot.img, using zimage + new packed ramdisk, using correct mkbootimg arguments
6) flash using fastboot
7) enjoy
PRO TIP:
Use ONLY LINUX FOR ALL OF THIS ELSE DEVICE WONT BOOT

Thats pretty much exactly what I did. (I did the initial split under windows though I will try again.)
I used the mkbootimg arguments from SE's building kernel blogpost.

Hey Doom, I'm trying to follow this, and I'm getting stuck
I downloaded the R800x 2.3.3 (3.0.1.E.0.88) TFT from here: http://forum.xda-developers.com/showpost.php?p=19438024&postcount=12
I unzipped it using xarchiver (installed on arch linux/available on sourceforge)
I ran unpack-kernelsin.pl, and I get two errors (that don't exit out of the perl script):
1) ramdisk written... gzip: no such file or directory
2) cpio: premature end of image
When I try to cpio-ing the ram disk, my computer just sits... How long should I wait, I have a netbook (i know, not the best for doing compiling) and the longest i've let it sit is about 10 minutes (i'm about to let it sit overnight to see if it'll work itself out)
If you could give me any pointers, that'd be outstanding
Thank you,
Pax
