Hi, i work on kernel only, from Alexander's repository.
You can update only the kernel whith fastboot, using boot img from archive.
Of course, given "as it", if your phone may unlikely be damaged, i'm not responsible for it. I'm just sharing with interrested people work i do for myself.

g3434d04 http://www.file-upload.net/download-4098661/update.zip.html

This new corrects :
* framebuffer that isn't updated after resume while there isn't external event.
(black screen when out of suspend)
* battery management

Remaining to do :
* libgps
* Fix the Wifi indicator up in the status bar to correspond to its signal strength + wifi & BT mac adress
* Wifi crash when connected and device suspended
* When go to plane mode and come back from it, phone call terminate immediatly.
* Often, data connexion need to be relaunched
* better camera support + frontal camera
* fat partition on sdcard at boot (but not prioritary on my mind, and might not be a kernel problem).
* fm radio
* Light sensor for the LCD

The same, reverting modif for volume keys :
g3803607 : http://www.file-upload.net/download-4104515/update.zip.html
Found battery datasheet :) : http://www.digchip.com/datasheets/parts/datasheet/280/DS2746-pdf.php
There's a register to correct accum capacity register increase. Added support of it when battery seems full and not charging anymore.
Found more information about the accu capacity register. So i modifyed the comportement (accum value correction) for low value.
But not tested, battery still not low enough.
Edit : low value accum value correction does not work at all. You should not use this version. Ill reread datasheet monday.
Edit2: bug of shame found :-s
unsigned char i2c_msg[3];
i2c_msg[0] = r;
- i2c_msg[2] = v & 0xFF;
+ i2c_msg[1] = v & 0xFF;
i2c_master_send(pclient, i2c_msg, 2);

Some people asked me how to rebuild boot.img. Here is a way to do.
You should use debian whith classic dev tools packages (arm gcc, git, etc ...).
It's easyier to make a script to make compilation and resend by fastboot.

# Get boottools
git clone https://github.com/AndroidRoot/BootTools.git
cd BootTools
make
cd ..

# Get and build kernel (if you want to use mine)
git clone git://gitorious.org/~poussevin/linux-on-qualcomm-s-msm/tp-alex-linux-xperia.gi
t -b android-2.6.35

cd tp-alex-linux-xperia
cp arch/arm/configs/htc_msm_android_defconfig .config
make ARCH=arm CROSS_COMPILE=arm-none-linux-gnueabi- TARGET_BOARD_PLATFORM=msm7k
make ARCH=arm CROSS_COMPILE=arm-none-linux-gnueabi- TARGET_BOARD_PLATFORM=msm7k modules
rm -rf modules_path
mkdir modules_path
make ARCH=arm CROSS_COMPILE=arm-none-linux-gnueabi- TARGET_BOARD_PLATFORM=msm7k INSTALL_MOD_PATH=modules_path modules_install
cd ..

# Recreate bootdir
rm -rf newboot
mkdir newboot
cd newboot/

# Unpack original boot.img
export PATH=../BootTools/:$PATH
cp ../boot.img .
../BootTools/unpack-bootimg.sh boot.img
rm -rf boot.img-ramdisk/lib

# Replace image
cp ../tp-alex-linux-xperia/arch/arm/boot/zImage boot.img-kernel

# Change minimum cpu freq
sed -i 's/min_freq 122880/min_freq 19200/g' boot.img-ramdisk/init.kovsky.rc

# Add modules
cp -rf ../tp-alex-linux-xperia/modules_path/* boot.img-ramdisk

# Rebuild boot.img
rm boot.img-ramdisk.cpio.gz
cd boot.img-ramdisk
find . | cpio -o -H newc | gzip > ../boot.img-ramdisk.cpio.gz
cd ..
mkbootimg --cmdline "fbcon=rotate:2 smd_rpcrouter.hot_boot=1 no_console_suspend" --kernel boot.img-kernel --ramdisk boot.img-ramdisk.cpio.gz -o boot_new.img
cp boot_new.img ../boot.img
cd ..
rm -rf newboot

yay that means no more waking up issues?

awesome!

how to flash via fastboot? only: fastboot flash /boot boot.img that's all?

could you also add to your list to solve the wifi issues and detecting of wifi mac address? that would be nice ;)

EDIT: and also usb and adb?:p

it would be nice if some day everytihng works...

This new version, g3434d04 corrects :
* framebuffer that isn't updated after resume while there isn't external event.
(black screen when out of suspend)


I guess that means the black screen issue on calls, and when you wake the phone is fixed?

did you noticed my last answer in old thread about battery life? http://xdaforums.com/showpost.php?p=22301471&postcount=280

By fastboot, syntax is :
fastboot flash boot boot.img
You cant put phone on fastboot mode by rebooting to bootloader, or holding power button while starting.

About battery, i didn't really understand your explanation. When you keep charging while ratio is 100%, it continues to charge, and maximum value used for ratio is updated.

About wifi mac address, it's not a priority for me. I use only 3G data (in france there is a cheap unlimited phone bill ...). And i work for my use at first. But ok, i add it.

you don't have to do it. it was only a question of course but thanks ;)
surely you should do your stuff first

i ment there's a unknown point when charging with 100%, where the indicator starts to go down again. this one i've to strike to get better battery life but i never got the battery life i had with indicator stucked at 1%

Guys, I haven't tested the nand version yet.
Could someone who is using it confirm whether location service via mobile network is working with this kernel? I remember it was working fine in older Froyo based SD builds, but will all newer builds i have tested (Jerrytan, Kuskro,...) only location service via GPS was working in google maps.
Thank you in advance.

Also got a suggestion, Not an important one :)

- Fix the Wifi indicator up in the status bar to correspond to its signal strength

and thx zargloub, todays build is working fine for me!

yep it looks like the waking up issue is solved... will test later.

@zargloub great work! the battery indicator now don't goes down after a while. but now the battery is running hot after some time charging an the indicator is still messed up after reboot. but i think you already know that ;)

btw is the usb storage or adb working for someone

What about the battery?)
I try your updates but it became worse since 24.01(date of file) version. That version works just about perfect for me. And of course - buttons issue(qwerty,end call) we need those :).

And I also think there are a few more important "to do's".

Light sensor for the LCD (very important for battery consumption)
Proper 3D drivers for GPU (in windows Video performance is better). (Angry birds :( run in slideshow mode, and video has to be severly cut so that SW acceleration in players works fine)
Missed call? Or is it solved?

Yeap FM radio is important for sure).

One more thing. All the operations that make the phone heat up - severely drain the battery. Take care of that.

FIRST of all the basic feature, so we have good battery performance (quite good), and phone features working inkl mobile data (checked), then wifi, graphics and then GPS, camera, fm radio (I don't know why people use/need it).

The rom is quite perfect with working phone features, mobile data, graphics and gps (don't need bluetooth, fm radio, camera (special feature but not realy needed, wifi isn't any more important because of mobile data plan)

Will flash now. Download server is quite good ;) but if someone wants a mirror I will make one.

Edit: I just flashed boot.img and booting with SD-Card is still working for me ;)
I used my current rom -> didn't installed the update.zip file via CWM
so when just the kernel has been changed it should be the same as this

has someone the same experiences that sometimes when i want to make a call the phone immediately hangs the call up again and i have to wait some time in sleep mode till it works again?

Edit: mostly it works but sometimes...

Just asking. The file in the first post is 70+MB. If I want to start using the NAND ROM, I just flash that in the CWM once I do the LK bootloader stuff?

Could someone please point me to the latest ROM if the one in the first page is not the actual ROM?

Is this one: http://xdaforums.com/showpost.php?p=22014505&postcount=226

newer than the one on the first post?

Many thanks.

    Hi, thank all for your proposals, Elibl said he send me one.
    I didn't realied so many people were using this kernel.
    So i have a wonderfull phone for everyday (Defy+ is a good choice), and when i'll have an alive battery and some time i'll continue to work on the kernel.

    For now battery is still near the x1 on my desk. I got it back from my daugther,
    Lot of work this month, but i'll have a look as soon as i'll have some free time. Don't worry :)

    I think I finally have gotten somewhere with the battery drain. Alex had written some code to turn of power to the LCD-panel, but he had put a "return;" in front of it. I removed it and Voilá: Lower battery drain :D

    You do get some artifacts on the screen when going out of suspend. I think this is just an annoyance, but I have just tested it since last night.

    I just uploaded a boot.img file.

    It's a bit more complicated.
    There's an internal register in the battery, that increase or decrease, managed by battery chip.
    We can correct values, when we estimate it's not good, in the driver (for example, if you don't do anything, the register grows while it's pluged, even if charge finished).
    We estimate in the driver the "full" value of this register, and calculate ratio with it.
