Help, I got a replacement phone and wiped the ROM without having a flashable one replace it. I had a backup from my from my old phone, but I zipped it to get it off my old phone. I was going to restore the back up, but I forgot to unzip it. I now can only boot into TWRP Recovery, and I don't know how to get the unzipped backup or a flashable ROM on the phone. Any help would be appreciated.
