Here's the OP
[ROM] DarkSlide v4
Follow the install instructions exactly.
I'd suggest if you don't have it, before you do this, you get the "Droid X Bootstrapper" app from the market- use or press "bootstrap recovery" to make sure you have it working, then press "reboot recovery", and you will end up in the right screens to backup your current ROM, and then follow the directions in the OP above to install Darkslide V4.
I'd recommend the "blurred" version (just as fast, less trouble) and remember, when you wipe data/cache, you will have to do the setup from the android prompt just like when you got your phone- entering your gmail address and password, which will also recover all your market apps and contacts. If you had facebook for pix in contacts, you may just have to readd that account too, but most of that work gets done for you just by re-adding your acccounts when everything syncs.
I just wanted to make sure that you understand when you wipe data to install this, you'll have to re-enter those things, but everything you had will come back, reinstalled from gmail and market.
You might have never done a data wipe before.
Cheers!
