[Fire TV Android Development] LocoMexican:
OK, I have checked edits on the script and then connected the board to my computer. It gives me the following message:

Unable to Mount 6.1 GB Volume

Error mounting /dev/sdb20 at /media/locomex12/57f8f4bc-abf4-655f-bf67-946fc0f9f25b2: Command-line `mount -t "ext4" -o "uhelper=udisks2,nodev,nosuid" "/dev/sdb20" "/media/locomex12/57f8f4bc-abf4-655f-bf67-946fc0f9f25b2"' exited with non-zero exit status 32: mount: wrong fs type, bad option, bad superblock on /dev/sdb20,

missing codepage or helper program, or other error

In some cases useful info is found in syslog - try

dmesg | tail or so.

I disregarded the error message and reflashed the device with the correctly edited "flash.sh". This is what the terminal shows:

locomex12@locomex12-Presario-C700-Notebook-PC:~/Desktop/Folder-5.2.7.0$ sudo ./flash.sh

I'll disconnect my adapter and see if I can get back into twrp and go from there.

In twrp, under mount, it shows cache, data, system, and usb. However, only cache, system and usb allows me to check; i.e. the data will not allow the box to be checked.
