[XPERIA X10 Android Development] CosmicDan:
This ROM is no longer being developed, I have moved on to the Xperia Play. I will help as much as I can whenever I can.

Introduction

This is seriously the fastest X10 MIUI I have ever used after installing my many background apps for gaming, working, typing, browsing, everything. This is a production of my own kitchen and also seems to be 100% stable and very compatible in all my extensive tests. It is built upon FXP and MIUI UK's build of 2.4.20 (for the Incredible S). I am taking the time to research and test every small tweak out there for the X10 and hope to create a perfect stock-like MIUI ROM, which I think I have done - but I'll let you decide ;)

Features:

- Supports many languages, including Right-To-Left

- Exclusive tweaks specific to the CosmicUI and the X10i (very snappy with multitasking)

- Uses WebKit Core and DalvikVM from FXP, providing the fastest MIUI ROM for X10 yet

- Aroma graphical installer with various options to suit your needs

- Native screenshot working with Menu + VolDown key

- Mi Button option to remap camera key

- "Performance" menu, based on CM7 Performance Menu, for setting CPU and CompCache settings

- Aroma Installer for customizing the install

Installation

:

0) Factory Reset recommended if upgrading to v0.6.x

1) Flash baseband .71 if required (for X10i, this ROM is not tested on X10a)

2) Flash the kCernel CosmicMod (recommended), which is based on kCernel_v01 with 730MB on /data and OC capability, or alternatively use any FXP-based kernel (for advanced users), or the old one from 0.4 if you don't want a bigger /data partition for some reason (check my Mediafire folder). Wifi modules flash not needed. Note - CosmicUI kernel is based on kCernel, all credits go to champ.

3) Download the ROM CosmicUI-vx.x.xx.xxx ZIP (see newest version in "Downloads" below) and install in Recovery. Highly recommended to perform a Factory Reset. Also install any hotfixes after (you can reboot if you want, doesn't matter).

4) When the ROM loads, it will automatically reboot once/twice (depending on what customizations you chose).

5) If you get stuck at kernel logo after the install, repeat everything from step 1 again. Sometimes the X10 gets a bad flash.

Note: Do NOT use the old v0.3 Modpack ZIP with the new versions! v0.4 onwards use the graphical Aroma Installer that allows you to chose mods there.

Note 2: The new kernel uses Touch Recovery y DoomLord/Team UtterChaos. If you made Nandroid backups with FXP CWR on previous versions, it is 100% compatible with them. If you still want CWR and/or Bootmanager, use champs' original kCernel.

Downloads:

DO NOT MIRROR. If I find mirrors in Google I will remove this ROM from the public! An honest thank you to the various Middle-Eastern and Asian forums for linking to this original thread :)

If you are updating from v0.5 to v0.6 you may need to perform a Factory Reset to fix some things. At the very least, do a "Clear Data" for any app that FC's or performs strangely after update. Please do NOT report bugs if you have not done a Factory Reset in Recovery!

Screenshots:

(These are from the old v0.3, v0.4 onwards has a new default theme in the style of screenshot 6 and 7)

Description of each, in order -

01 - Desktop

02 - Settings > System > Performance menu

03 - Showing the new "Mi Button" option for remapping the Camera key (personally I like to have it set to MultiTasking Pro)

04 - Auto-Brightness settings disabled because it doesn't exist on the X10, and a reminder to reboot

05 - Music player (working 100% now, Equalizer removed completely but fade working)

06 - My personal (heavy) desktop setup. QQ Launcher, Beautiful Widgets, Minimalistic Text, Wifi Manager, and the shortcut icons is a widget from Folder Organizer (it allows smaller grid size than stock launcher icons, and resizes icons better quality than the Multicon Widget).

07 - Quadrant Benchmark with a number that doesn't really mean much... try the ROM yourself for the real feel ;)
