Also, on the developer page, it says to use one recovery vs another. Is this mandatory or it just the developer's personal preference?
The reason I ask is that when I first rooted my phone I flashed TWRP and did a back up. Then, to get this other ROM on my phone, it was said to use CWM, which I flashed in place of TWRP. If I wanted to go back to my original backup, would I need to reflash TWRP so that I could restore that back up?
Thanks in advance.
