Wiped System Partition... No OS.. How can I recover it back? I successfully installed TWRP yesterday on my phone and then wanted to root it, but before doing that, I wanted to do a Full-Wipe of my phone, just leaving the phone with the OS, but for some reason, I left the System Partition Wipe option enabled and Wiped it. Now, I'm stuck in a bootloop without an OS, and I can only access TWRP and Download Mode.

How can I recover the system/install the OS again?
