Disclaimer: this is for testing only, I assume no liablity to any potential damage. If you feel this is a violation to your copyrighted software, feel free to contact me and I will respond accordingly.

It's released only on forum.xda-developers.com and bbs.mfunz.com , please refer to either thread depending on you prefered language.

Hi, after a few days of trying, I'm releasing a prelimitary Dual OS solution for Defy. It's not very complete yet but it's good enough for daily use (the 'dual' part, not the MS2 port or MIUI).

Before you ask, yes I've tried using SDCARD (system+data or data-only), it's just too slow for daily use. app2sd would be a better solution.

Features:

  • Well it's a Dual OS, what can I say. (MS2 port + MIUI)
  • You can update the two system independently (admittedly a bit hard for the 2nd OS as of now)
  • Advance Settings in the 1st OS, try it!

Draw backs:

  • It eats up 327MB (may size down a bit in future releases) of your /data and the two OS use the same space for it's apps so you have 700~800MB free /data to split between two systems. I'm using memhack to save some space.
  • The two OS included isn't very stable
  • Only 2.2 kernel supported as of now

Installation:

  1. Root your defy and install any ClockWorkMod/Bootmenu/Snd-init if you don't already have one
  2. Download the RAR file and extract 'clockworkmod' folder to the root directory of your SDCARD
  3. Boot to your CWM, choose restore, and restore "DualDefy_v2.11". DO NOT WIPE after restoring or you loose the 2nd system.
  4. Reboot system and it will boot into the primary system
  5. To enter MIUI, press VolDown during blue LED when booting and enter Bootmenu, choose boot -> 2nd-boot and wait
Note:
It will reboot once during first-ever boot to generate a overclock(etc.) config file. *Do not use the overclock function in bootmenu* It's in "Settings -> Advanced Settings".

How to wipe:
To perform a wipe correctly (without loosing one of the system), follow the instructions:


  • To wipe 2nd OS, just delete /data/2nd-data with RootExplorer or "adb shell rm -r /data/2nd-data" in the CMD/Terminal window without quote. -- While booted into th 1st OS of course
  • To perform a full wipe, backup the 2nd OS, just copy /data/system.img to the root of your SDCARD (/sdcard/system.img), the wip as you normally do. It will be copied back if you choose 2nd-boot again.
  • To wipe the 1st OS: boot into 2nd OS, delete everything in /data2 except "/data2/2nd-data" folder and "/data2/system.img"
Thanks:

To all the devs who layed the ground work (Skrilax_CZ, CyanogenDefy team and many more) which ultimately made this possible.
And thanks to all the people who were helping me test it over at bbs.mfunz.com

Interesting finding. Let's hope it will come a day when we could select those 2 ROM's that are installed... so it will be possible install a stable ROM as primary, for daily use, while for the second we can opt for some test beta ROM's.

It has been publicly tested for green lens -- was made for green lens after all

Sent from my MB860
He want to say: the video didnt work for green lens (same is at mine) on MS2 not MIUI.
pictures are ok, i can make pics and see them in gallery.
when i press on video mode and start, the application block himself and no video recording.

And for the second rom (you chose MIUI) better please chose the MIUI from miuiandroid.com because the one from miui.us have many, many chinesse letter in menu after i chose english (i just tryed).

Will be nice when all work fine to help us and learn how to put 2 roms that we want :)

Sorry, missed that spot:eek:, it wasn't done by me and there are many many things I'm dissatisfied about the one I released.

This was put together in a rush before I have no time (like right now) to do anything further.

I am planning on making it a bit more flexible. And I have already made MIUI OTA via recovery usable as of now.

I'll be doing a more simplified version with easier scripting to aid other dev. Just give me some time pls.
