timmmay: I didn't really understand much of that Jeff. I backed up to external SD card using titanium pro, copied that to my PC.
You're saying I flash Philz Touch using Odin, that lets me back up my existing ROM/firmware to external SD card so if a flash goes bad I can recover? I assume Philz Touch replaces Android System Recovery? Are there any downside?
Titanium backup only backs up your apps but nandroid takes an image and just replaces it so everything is as it was beforehand. I only suggested custom recovery as you are rooted anyway so may as well go whole hog. Only downside is the same as rootung, you don't get OTA updates but the flipside is you can get the latest and greatest when you want and as I said you have already rooted so the nerve wracking part is done.
Just pushing you, not so gently, to flash custom Rom as I think you won't look back once you have ;)
