Don't unzip the file. I'm not sure what you mean by it "showing up as two folders"-it should download and appear as one file if you are just doing a normal download.
Can you provide more details on what exactly you are doing?
Also, have you rooted already? If not, those files won't help you- you need to be rooted before you flash a custom ROM.[/QUOTE]
I download the file that they tell me to, which is Update.zip and instead of getting the icon and it saying update.zip its two different things instead.
im not rooted yet either.[/QUOTE]
Interesting, i guess I've never seen that.
OK, first things first-you need to get rooted (and some additional homework to some of the basics would be beneficial to you). There are plenty of threads on the forum to guide you through the process, these can be found with a search (HINT: Use the Google search instead of the native search, it works much better).
Next, you will want some navigation tools, such as Astro, if you don't already have them.
Finally, the Hacking section of this forum is where you probably want to be, as there is a lot of help available there.
A word of caution-please do research before you jump off the cliff (you are doing the right thing by asking questions here). Rooting and playing with ROMs is great, but odd things can happen. It is extremely difficult to completely kill your phone, but recovering from issues will be easier if you understand the basics of working with recovery, backing up nandroids, etc. My signature is particularly appropriate with this stuff
I know you want to dive right in and get started, but a bit of reading and research will pay off and save you time and frustration if you run into issues.
Again, resources on all of that can be found with a search.
Welcome to the forum and good luck.
