So far I have taken the factory incredible load and rooted it using the unrevoked tool. I've played with some root apps and now i'm ready to play with froyo. The thing is I want to be able to go back to the factory load at anytime. I'm not sure if I like the vanilla or sense interface better so I was thinking about trying the OTA leak and Cynogen 6. The question is how easy is it to switch between ROMS and is it possible to go back the factory load so I could get the official OTA Froyo update (for if and when I get tired of playing with root)? I keep reading that loading Froyo requires an update of the radio previous to loading the ROM. Is the radio downgraded automatically if you installed the original factory ROM again?
Anyone recommend another ROM for me to try?
yes you can easily switch between roms. everytime you install and load a new rom, if you like it, go into rom manger and select backup current rom. name it something that makes it obvious which rom that is for future reference.
you can go into rom manager and either select install rom from sd card, if you've downloaded a rom off the internet, or you can select download rom, and select from 3 different roms, cyanogenmod, skyraider, or jagerrom, (jagerrom is hilarious). or you can go to managed and restore backups, and select a backup you've made.
coupe things to note, when installing a fresh ROM through rom manager, always select wipe data and cache. (this does not apply to kernels, when isntalling a kernel do NOT select wipe data and cache).
you can run froyo right now without the radio update, you just won't have a camcorder. they did finally get the camera working and everything else is stable (atleast on the cyanogenmod6 test8 rom, that's the only froyo rom i've run for an extended period of time). if you update the radio, you can try skyraider (if you're the kinda guy who's into sense) or jager (if you hate sense, like me) and everything should work, including the camcorder.
IMPORTANT!!!!!
when updating your radio, there are two things you must not do. do not ever take your battery out. Not until it's painfully obvious the whole process is over. if your screen is blank and you feel like it's frozen, DO NOTHING. let it sit overnight if you have to. if you remove the battery your phone will be a brick. also, do NOT under any circumstance apply the update.zip twice. once the radio is updated, and everything is good to go, get into your SD card and remove the update.zip file. if you apply the update.zip twice I hear that will also brick your phone.
most important thing regarding roms, backup backup backup!
