Can't install ROM on TWRP (Xperia S)
I've got an old Xperia S currently running TWRP 22.214.171.124 (the latest version). I'm trying to install cyanogenmod on there but the recovery doesn't seem to work with adb sideloading and USB OTG doesn't seem to show up. I also can't seem to mount the phone's internal memory to my computer. The phone is wiped so I cannot access the actual system. Therefore, I cannot install a ROM on there. TWRP is the only recovery I could find which worked and so I cannot use a different recovery (unless you know of one). I now have a phone which cannot access any external files for installation and without a ROM. Help.
