If I download this via ROM manager and then want to go back do I just restore the ROM I just backed up...what happens to the SkyRaider? Sorry for all the questions Im a little nervous as this will be my first time changing ROM's.
Dont be sorry for any questions.
A backup basically freezes your phone exactly as it is right this moment. Call history, browsing history, navigation history, settings, etc.
If you flash a rom and dont like it, you flash right back to your backup and its like nothing has changed.
Its for this reason a lot people will probably have a backup folder looking something like this:
Backup: Stock, before root
Backup: Stock, after fresh root
Backup: SkyRaider 3.2 (fully setup)
Backup: SkyRaider 3.3 (fully setup)
Backup: SkyRaider 3.3.1 (fully setup)
Backup: Virtuous (fully setup)
Backup: MIUI (fully setup)
Backup: SkyRaider 3.3, KK#5 Kernal
etc etc
This helps in a few ways ...
1. If your on a ROM that you like, and all of a sudden get a bug out of nowhere, you flash back to before the bug happened
2. If you flash a new rom and it puts you in a boot loop, or gps doesnt work, or you dont like it for whatever reason, you flash back to the one you liked
3. You can test new rom/kernal/radio options with little effort, make the change and see if its good, otherwise flash back
etc, you get the idea
