(This is not necessarily a TWRP issue but if I have any options left it's almost certainly going to involve TWRP so...)
The system & vendor partitions on my Pixel C seems to have been erased as I learned (the hard way) how to use TWRP (3.6.1).
--The device is unlocked.
-- adb & fastboot still work
-- the data partition was reformatted so TWRP doesn't ask for passwords
-- I can still get to the bootloader screen and recovery.
-- I have TWRP installed but it can't see my USB-OTG drive now - although it used to be able to - so I can't install anything from TWRP.
-- I tried to sideload LOS 15.1 but it failed with these errors in TWRP:
Code:
]Failed to mount '/system (invalid argument)

Then I tried to install factory 8.1 image from fastboot. It failed with the following console errors:

What can I do to get ANYTHING installed on this device?
