Below is a link to an Auto-DeOdexer that I created.
What's in the file? I used xUltimate's program 2.2.3 to DeOdex the Leaked OTA updated phone. Took the deodexed files and created the proper script (Thanks 928Droid for the inspiration!) to install the files and get rid of the Odex files.
I took a test Droid X.... updated to 2.3.3 / 4.5.596... was previously rooted... bootstrapped.... and installed the above linked file that I created.
Starting from a clean 2.3.340 SBF... factory reseted phone... and used Z4Root to root.... then updated to GB 2.3.3 / 4.5.596... and it worked beautifully. Installed my theme... and done!
Step by Step:
As long as your phone has a clean system with 2.3.3 / 4.5.596 on it, this should work fine. Doing a data wipe may not be necessary, but if you are having issues, attempt to do that as well.
1. AS ALWAYS! Perform a backup before DeOdexing your phone!
2. Root your phone with Z4Root. I've used 1.3.0 several times on a fresh 2.3.340 install without ever having a problem. Then updated to 2.3.3 / 4.5.596.
3. Install Droid X Bootstrapper by ClockworkMod found in the Market. Once installed, Bootstrap Recovery... then Reboot Recovery.
4. Once in recovery, go to install from zip, find this zip on your sdcard, and install.
5. Reboot and Enjoy!
I put a script at the beginning of this to check build.prop for the latest 4.5.596. If you have a modified build.prop or are not on 4.5.596... it should fail. I haven't been daring enough to install another build and attempt using this, so if you are that daring... feel free to do so. On 2.3.3 / 4.5.596... it gets past this without issue.
I take no responsibility for what you do to your phone. This update works on rooted phones only. Currently I've only tested with Droid X Bootstrapper Recovery. Disable USB Debugging in order to use Droid X Bootstrapper. If someone is able to use Droid 2 Bootstrapper... then let me know.
