We are glad to present our kernel and ROM for Xperia Ray (st18i).

Stock-based ROM with cutting all no-necessary software. Kernel assembled from sources with usefull modifications.

ROM is very light-weight but powerful. There are NO any google apps in ROM. This is our rule. You can install it from "standard" GAPPS packadge from CM 7.2 topic.
You may use kernel with our rom or with your own stock-based rom including full stock, with any baseband. (we recommend 58 radio).
Both the kernel and the rom have passed test many weeks before we offer it to you.

ROM features:

- removed bloatware: google apps, SE anonymous statistics, adobe apps, ant+ apps, datamonitor, devicemonitor, facebook apps, timescape and all of their integrations. Thus, you have a lot of space for your programs.
- all other good and useful SE apps are still here: player, gallery, camera (including 3D), FM radio, TrackID, browser, default launcher.
- root and Superuser software are included
- useful switches in notification area, clean and precise battery indicator

ROM downloads:
primary mirror: http://narod.ru/disk/35145199001/ST1...PDA_6.zip.html
secondary mirror: http://www.multiupload.com/VAOQ83X1SX

Kernel features:

- kernel is assembled from SE sources with usefull modifications
- cwm recovery
- light and balanced overclock up to 1.4 GHz (we leave SE frequences grid) (default frequence range: 122 MHz - 1 GHz)
- deep undervolting but working under hard loading
- default and recommended governeur is SmartassV2 (we have been testing power savings for some weeks with many different kernel settings!)
- support for dual channel voice call recording (with CallRecorder software by skvalex)
- as a result, power consuming is just a bit higher in overclocked mode and usually much less than on stock firmware
- guaranted very deep sleep in suspend mode
- very stable work and all-sides-testing

Kernel downloads:
primary mirror: http://narod.ru/disk/36316696001/bootuv5.img.html
secondary mirror: http://www.multiupload.com/UKGMCCMX2C

Installation procedure is usual:

- download rom & kernel
- put rom into sdcard
- you can also put gapps package into sdcard if you want to install Google apps
- reboot your phone to "fastboot mode" (switch off power, press Vol+ button and plug USB cable)
- flash kernel with command 'fastboot flash boot bootuv4.img'
- unplug cable, power on phone, press Vol- when the screen becomes bright for entering to recovery
- select 'backup' option and backup your previous firmware (just for safety reason)
- you DON'T need to clear user data -- wipe is not required!
- select 'install zip', select our rom file, wait for installing firmware
- install gapps package with the same command, if you need it
- select 'reboot'
You get a new rom!

Our plans:
- we are constantly searching for new features to implement into a kernel
- we are testing a kernel with the new approach now, with new compression, with new init.d feature
- stay with us))

I'm considering flashing your ROM, but why wouldn't you let us overclock to 1.9 or 2.0 Ghz and "only" to 1.4 Ghz?

Just flash hartej/DoomLord Kernel if you want to OC higher...

Yeah I have that one flashed already, but I would like to know if this one is "better".
To Aire: What can the kernel of this ROM do more that DoomLord's kernel? In other words, why should I use yours and not DoomLord's?

I am so happy that aire post his great work here!!!!

I am using both kernel and ROM for more than 1 week and I can tell you that is the best in term of stability, speed and battery.

I so frequent checking the 4PDA forum for your work and use Google translate the message. So most of the time is guessing, and now you are here... thank you.. big thank you.

Actually you can just try it out yourself to compare the difference and tell us about your finding.

What I found is without further setting, compare to DoomLord's kernel, the battery life is much better in this kernel.

thanks for your interest, guys!

while we prepared this first post (translate it) for bootuv4, aire has released a new kernel bootuv5. But translated features remained from previous ver. Now I will write up-to-dated features for you.
(so what you read 'in our plans' -- this is not future but presence release features)))

bootuv5 features:
- extremal undervolting at all frequencies
- filesystem support: ext2, ext3, ext4, yaffs2, vfat, ntfs
- overclock up to 1.4 GHz (work range 122 - 1024 GHz)
- init.d support
- default (and recommended!) governor is smartassV2
- ClockWorkMod Recovery 5.0.2.7
- anonymous services support removed (from kernel)
- fota support removed (from kernel)
- bidirectional calls recording

about 1.4 ghz.. Guys, SE kernel has calculated the manufacturer a grid of frequencies, if we add intermediate frequencies or overclock frequencies in table pll2_tbl (in kernel settings) -- in any case we have increasing a consumption.
We don't know how DoomLord has calculate this expanded table but all our tests says that battery drains more rapidly than on the default table. EVEN IF you will set 'default' 1ghz frequency in overclocked (to 1.8-2 ghz) kernel the consumption will NOT as at SE kernel, SE frequencies grid. The reason consists in it.
In real tasks enough 1.4 ghz, guys! But phone perfectly sleeps)) Any percent doesn't spend for a night. Is this not enough?

About init.d. In last repack4PDA (rom) the training script which is in a folder /etc/init.d is added. It named 'Scpufreq' and consists some commands to init default frequencies range and def. governor. You may try to change it for you taste)) But note that names of your scripts MUST begins from upper-case 'S', and permissions must be as r-xr-xr-x.

We will try to answer your questions, because aire have no time to read this topic.

ps. Don't forget that we tested more than month several kernel assembles and give you checked up Emerald))

Good to see another dev here! I Was using your latest kernel with stock .42 rom from SE for a little week or 2. Worked brilliant. Now I have flashed this rom, the repack4pda .58 version, and I am experiencing severe batterydrain in standby. Overnight I lost 26% when the phone was laying idle on my desk. There were almost nog wakelocks present, phone was awake for 3 times. I had this once before, that was when I flashed the hongkong edition .58 rom posted elsewhere on xda for ray. I think it has something to do with the baseband of this rom.
I found another baseband here on xda (also provided by you, thanks) and flashed that. After the baseband I flashed your kernel. The rom you have made is very fast and sleek, so I hope that this will solve my problem. Otherwise I have to revert to stock .42 again and start deleting bloatware.

See this screenshot of my overnight drain:

didn't try this rom+kernel....yet.
I'm currently on stock rom + doomlord kernel (bloatware removed from ROM).

I notice better battery life (@same clock speeds as stock) after rooting "and" 'battery calibration' app (free from market).

So fully charge the phone, then when still on charger at 100%, press "calibrate".

Hopefully this tool will extend battery life further :)

Please send you comments/experiences about the battery calibration, I used this tool successfully on my previous samsung apollo.

I have used that tool before. On .42, I managed to last 51 hours with the phone. Now, when my battery reaches 10%, it goes to 1% and the phone shutsdown. I will try to erase batterystats from cwm as soon as my phone is fully charged again. I used to have a Desire HD, I wiped batterystats from cwm there all the time and that worked great.

you can try new kernel w/o reinstall rom. this rom just more clean than we can clear it 'by hands')) if your current rom is ok -- no need to reinstall it.

Question is not for this topic, I think. Recalibrate battery statistics file need if you reflash cyanogen after stock or vice versa. If your rom is stock usually no need battery file deleting.
If your battery drains quick (as it seems to you) at first, once a month it is necessary for us to discharge the battery completely, then charge it _without interruption_. And even allow be at charger 20-30 minutes after 100%. (NOT at all night!) Repeats this twice. After that a new statistics will register to battery file and phone will 'know' it real edges of 0 and 100 percents.
At second, need to see which apps wake phone up. You may install any special app for battery and processes monitoring, e.g. battery mix, and see it statistics after some days for who eat battery)).
