[Defy General] boonhoong:
This is a fantastic ROM! I can only say that I am very surprised to see this kind of quality interface coming from MOTO. Anyway, to help those who're new to this, I've written a somewhat comprehensive installation guide below.

Preparation

1.	Firstly, you’re going to need all these files

a.	Rooted-nandroid-backup + fixed sbf from http://www.multiupload.com/SPZ8SIEC60

b.	Superoneclick from http://xdaforums.com/showthread.php?t=803682

c.	Defy ClockworkMod Recovery from http://xdaforums.com/showthread.php?t=875233

d.	Latest RSD Lite and Drivers from http://xdaforums.com/showthread.php?t=1100585​

2.	Install the RSD Lite and appropriate drivers into your PC (32-bit or 64-bit)

3.	Follow instructions at the Superoneclick thread to root your Defy

4.	Follow instructions at the ClockworkMod Recovery thread to install System Recovery into your Defy

5.	Launch System Recovery and install Recovery System

6.	Perform Recovery Boot (USB debugging MUST BE TURNED OFF in your Defy. It’s located under Settings – Applications - Development)

7.	Create a nandroid backup of your current system by scrolling to “Backup & Restore” using VOL UP/DOWN key, and POWER button to execute (this is so that you can return revert back to your official ROM for warranty purposes)

8.	Reboot normally

9.	Extract the rooted nandroid backup + fixed sbf file you downloaded earlier. The filename should be “shadow4.5.1-134rootednandroid.zip”. You should see 2 folders “fixed-sbf” and “nandroid backuo”

10.	Copy the “shadow4.5.1-134nandroid” folder (not just files, but the whole folder) to your SD card under “\goapkrev\backup”. So you should have “\goapkrev\backup\shadow4.5.1-134nandroid” in your SD card.

Actual Flashing Process

1.	Launch System Recovery and perform a Recovery Boot (USB debugging MUST BE TURNED OFF in your DEFY. It’s located under Settings > Applications > Development)

2.	At the bootmenu, use the VOL UP/DOWN key to move through the boot menu and perform a full wipe (Wipe DATA/Factory reset & Wipe CACHE Partition)

3.	After both wipes are complete, go to “Backup & Restore” > “Restore” > “Advanced Restore” and you should see 2 items. Your earlier backup as well as the folder you put in earlier “shadow4.5.1-134nandroid”.

4.	Select “shadow4.5.1-134nandroid” and choose “System Only”

5.	After the restoration is complete, choose “Reboot System”, and IMMEDIATELY hold down the VOL UP key.

6.	This will put you in bootloader mode.

7.	Launch RSD Lite on your PC, and connect your DEFY to your PC

8.	Let the appropriate driver installations take place

9.	Select the fixed sbf file from the “fixed-sbf” folder. The filename should be “shadow4.5.1-134fixed.sbf” and Flash your DEFY

10.	Be aware of the flashing progress. It’s very fast.

11.	As soon as you see your device reboot, IMMEDIATELY hold down the VOL DOWN key.

12.	This will bring you to stock recovery. Press both VOL UP and VOL DOWN key simultaneously to see the boot menu. Select items with the VOL UP/DOWN key, and POWER button to execute.

13.	Perform a full wipe (wipe data/factory reset & wipe cache partition)

14.	After both wipes are complete, hit “reboot system now”

15.	Once your device completes the normal boot up process, RSD Lite should show the “PASS” status. Close RSD Lite and unplug your DEFY from your PC.

16.	Enjoy!
