Updating TWRP and various Root questions

Alfa_G said:

I've flashed via odin the TWRP recovery before I installed the v30 omega rom. 2 days ago I flashed the v31 and now the phone reboots randomly.I've tried to use logcat but i can't find the cause.In safe mode though the phone doesn't reboot So here is the deal:

I'll reflash the v31 since some features were NOT flashed like call button on contacts but i want to update the TWRP to its latest version....how?Through the TWRP manager app?Or flash it through odin?Flashing an updated version on an existing one recovery using odin won't be a problem right?Also,what jfltexx is the codename of my version right?(9505)

Also,a nandroid backup is basically an "image" of the phone right?Like a disk clone operation of acronis in windows....correct?

thanks for your time
