[Xperia Play Android Development] paxChristos:
FIRST OFF: THIS IS FOR UNLOCKED BOOTLOADERS. IF YOU TRY TO INSTALL THIS WITH A LOCKED BOOTLOADER, YOU WILL BRICK YOUR PHONE.

As aGraceful has been mentioning, Here is the CM9 thread dedicated to the R800x.

What it is:

We (myself, aGraceful or anybody else who's interested) will port FXP with every new release that comes out.

I (or if anybody else is interested) will be building & uploading a new version (from source) about mid-week (between FXP release) with the newest CM9 updates.

What it is not:

Neither myself, aGraceful, or anybody else who contributes claim any thing special about the code. Either FXP built it (if it's a port) or it's code from Cyangenmod/Koush/freexperia or anybody else who has contributed to the CM9/Android repos.

Starting 2012 June 06 -- I am using my own device tree and vendor tree to build this, so it should work better with wifi than FXP's builds.

Now, onto the good stuff.

What Works:

Data

Calls

Wifi

GPS

SMS

Accelerometer

MMS (thanks chrono!)

What Doesn't Work:

Bluetooth Media Audio (Thanks chrono!)

Video Recording (Thanks Neoandgeo for pointing that one out)

Facebook account syncing (Thanks DoubleByte) -- Note facebook account syncing looks like it's a problem within 4.0 framework...

Anything else that doesn't work, lemme know, I'll add it to the list.

FXP Changelog: changelog for fxp

Link to All Downloads

What's in it:

1) agraceful's port of FXP 115 116 117 (Current as of 04/22) I'm gonna stop hosting FXP ports through my mediafire, look to agraceful for those

2) mega_fix.zip -- contains Atarii's wifi/gamepad fix & 216monster's mms/carrier name fix

3) My latest build from source (newest date in the title)

4) Older builds

5) Copy of the libs I use for porting, If you're interested in trying to bring another ROM to our phone, these cover mostly everything) dev corner with some libs if you're interested in porting something.

Steps to do a install:

1) Download & copy to sdcard

2) reboot recovery,

3) MAKE A NANDROID!

4) wipe dalvik/cache

5) install from sdcard.

Steps to do a 100% clean install (we're talking if all else fails try this option)

1) Reboot into recovery, MAKE A NANDROID, wipe the 3 major things (data/cache/dalvik)

2) Turn off your phone & connect it in fastboot mode.

3) enter this fastboot erase system (this will erase the /system partition, insuring a clean install)

4) boot into recovery

5) install from zip.

Thanks to Ridder215215, a complete guide on how to install CM9 (just replace the link in line 2 with the link above)

As everybody knows, Flashing roms can lead to issues with your phone. When you decide to flash something, you are taking the responsibility for your phone working into your own hands.

Test update: 2012 April 11

Uploaded a xLoud test version for y'all to try out. Please tell me how well it works for you guys! (If it makes a big enough difference, I'll change out dspmanager for it)

1) Added in xLoud framework (kinda, I think we're missing stuff from framework.jar/framework-res.apk so it doesn't show up in menu-> sound settings) ALSO: It's having an issue with wrong UID (settingsProvider.apk issue) so when I get around to it, i'll tear apart some things and see if it can't be ported.

2) Removed DSP manager
