[T-Mobile Samsung Galaxy S II SGH-T989] Psiryu:
Android 4.3.1 ROM based on Cyanogenmod 10.2 nightlies

Tweaked for performance and battery life while retaining a stock CM experience. This rom is for the people out there who love CM and want to see it fly.

Want to see this rom go even faster? Use Nova or Apex launcher, and, inside developer options, set window animation scale, transition animation scale, and animator duration scale all to 0.5x.

Additions like HALO are not included to keep the bloat down, but can be included in future releases upon popular demand. I'm open to all suggestions or requests.

Changes from CM:

performance tweaks

network speed tweaks

sd read/write tweaks

other build.prop changes

zipaligned

init.d script support

uber kernel

compiled with linaro

custom boot animation

Viper Audio

removed stock apps:

CMFileManager.apk

CMWallpapers.apk

DSPManager.apk

LiveWallpapers (removed all live wallpapers, but live wallpaper picker left in place so you can still use your own)

(Think any other stock apps are just bloat and can be removed? Let me know)

Installation Instructions:

Warning: by installing this rom you accept all risks of modifying your phone. If anything goes wrong, whether it be bricking the phone or Godzilla attacking you, you take full responsibility.

Must be on a newer recovery and baseband, same deal as all other 4.3 roms.

1. Download the rom and 4.3 GAPPS to your phone.

2. Full wipe (cache, dalvik, system and data) if coming from a different rom or Android version, only cache and dalvik wipe if upgrading from a previous version of this rom or from stock CM

3. Install the rom

4. Install the GAPPS

5. Install any other kernels or mods you like (I'm personally a fan of the Fly On Mod)

6. Reboot. Wait until it finishes and boots up fully

Optional: 7. Give it 10 minutes to settle.

Recommended: 8. Install TricksterMod and change the governor from interactive. I prefer InterectiveX or OnDemandX, both of which go nicely with sio

Viper Audio Tips

Run the Viper app to set up the audio. You can choose between regular ound quality, super quality, or battery saving quality.

If you want to use any other sound mods along side Viper (I'm a fan of Noozxoide), be sure to go into the Viper app, hit the settings key and turn on the "compatible mode"

Want better sound quality? Check out the Impulse Response Sampling starter pack here: http://vipersaudio.com/blog/?page_id=115
