I was looking into flashing a rom on my razr and saw that safestrap is the recovery to use. I have read up on it quite a bit and think i get most of it and how it is different than CWM. Although I'm a little unclear on the what safe mode enabled/disabled does. When you make a back up of stock+root rom in "unsafe mode" then flash a new rom in "safe mode" can you switch back to "unsafe mode" and boot into your stock+root rom? Or if not what happens if you switch back to unsafe mode while running a custom rom?
