you have to go to themarkrt and download ROM MANAGER,this will let you get into clockwork recovery mode.Most ROMS come already deodex through themselves so if you want a ROM then you may not need to pre deodex.This 928Droid Themes for the Droid X is a great starting point that deodex your x and you can theme or ROM right over it and you dont have to worry because youwill be deodexed .Just be sure to follow all install instructions prior to doing anything .

 

if you download the team black hat app from the market you can download a 2.2 (2.3.15) deodexed rom and flash that to get deodexed.

you can flash it from rom manger or bootstrap recovery. as long as you are rooted.

 

ok you can do this two ways .....TOM108 way is very good ,personally prefer 928 since it deodexes and has a nice theme IMO.sorry about the first link as i saw it did not have proper instructions....Easy Deodex Droid X OTA 2.2 there should be what you need .Now either way you willl have to download ROM MANAGER for clockwork recovery .

 

ok you can move files by using root explorer or e strongs file manager or astro ....etc.....just be careful where you move them when and if you do ......yes you can create a new folder and just copy and paste your files into that folder.i personally like to use dropbox for all of my themes and roms but thats just me....ok now if i were you i would make a backup of how your x is now ,,that way you always have a clean slate to switch roms and whatnot...ok now you can install roms over 928 you are running now like i said just make a backup so if any problems occur as long as they are not too serious you can restore your backup.Yes you can theme over roms but not all themes can go over all roms ....prior to installing anything i would read up on it and see other peoples experiences with it.make sure you research and follow the instructions to the t!with thaat being said Fabs APEX V1.0 is my personal favorite.....ROM away my friend!
