Thanks for your help! Of course I have followup questions.
The radio combo updates hboot (I have 2.10) among other things as you mentioned. Do I need to flash this update prior to flashing ROMs?
Can I flash any of the ROMs located here:
HTC Supersonic/ROMs - XDA-Developers
Do I need to concern myself with which ones are AOSP and Sense? I prefer Sense UIs. Can I flash either?
My preference is to update to a stable phone state with gingerbread, with all the firmware and radios functioning (not still being worked on by devs).
Since rooting I've been to the custom recovery boot screen a couple of times. I've noticed there are other clockwork mod versions to choose from. Are there benefits? Do you recommend anything in particular, or go with what I rooted with?
Do you recommend a ROM manager app to facilitate flashing ROMs?
Also, am I correct in understanding you should never have your phone connected to power or USB when flashing?
Final question, are nandroid backups created from Recovery really all a person needs for recovery protection, or is an app such as Titanium backup highly encouraged?
Thank you!
