-Allows two system partitions
-One system is non-safe system where your main stock system resides. You can make and restore backups in this partition but you cannot install custom roms.
-The other system is safe system. This is the partion that lets you install roms and what not.
-You can toggle between the two systems from within safestrap recovery. It will automatically backup the current system before switching over.
-Safestrap has a nice feature that prevents bricks. On restart if Safestrap is installed there is a boot menu that pops up. You can hit the menu button to get into recovery from there. This comes in handy if you are having a bootloop. Just pull battery, restart phone and hit menu key when safestrap animation appears.
-One downside is that webtop doesn't work in safe system and the rom may run a tad bit slower in safe system partition
-This is the riskier one
-This is more like regular clockwork recovery. You boot intro recovery from the bootstrap app.
-You can make backups, install roms etc in bootstrap recovery
-If you enter a bootloop while using bootstrap recovery, your phone is pretty much bricked. Because of the encrypted bootloader there is not a way to get back into recovery if using bootstrap. You will have to use sbf/fxz from a pc computer to unbrick your phone.
