Okay, you're good to go
You need RSD Lite, a piece of PC software by Motorola, for flashing your phone. You'll have to googe for it, since we can't share warez here. Get the latest version you find! (I've got v4.5.7
)
After getting it, you should backup all your stuff. Everything that is in phones memory will be gone after flashing! You will need Flash&Backup 3.0.7 to completely backup your phone's software. You will need that in case your phone "dies".
You can check the MonsterPacks section now, to find something you want to flash on your E1
You need to get the "E1" version (or "0A.02 version") not the E398 (07.D0 version)!
I have to recommend you some older, legendary MP's! After them, feel free to flash anything new
First, Revolution v4, by Bodyguard! One of 2 best MPs ever for me

http://modmymobile.com/forums/7-e398-i398-rokr/240-back-black-mp-v1-0-a.htmlThose are 2 old MP's that I loved the most
(I've been into E398 modding for almost 6 years now) They are old, but they've got heart and they've got soul! New mp's have much more features, but I think you will be stunned by those two, since you never modded your phone...
If something is confusing you, please ask! Better safe than sorry
You can find some guides on the forums... Just ask anything about where you get stuck
Cheers!
