Recovery Issue with TCC8920 - Android Q&A, Help & Troubleshooting

Hi - I have a media streaming device I'm trying to salvage by attempting to update firmware (from vendor) but am unsuccessful due to issues during system recovery (so the new firmware is never applied). Some quick details on the device:
Hardware: tcc8920st_evm
Running Android 4.0.4 build
Connecting via onboard mini USB port
There are no external SD card ports
I'm able to connect successfully via adb (via usb port) and have root access
The system log shows it finds the update successful but appears to be having an issue mounting on one of the partitions (it doesn't exist from what I can tell). The error specifically is:
format: make_ext4fs failed (1) on /dev/block/mmcblk0p2mount: failed to mount /dev/block/mmcblk0p2 at /system: No such file or directory
What I think is happening is the update isn't taking since there's no partition for it to apply it to. My guess here is I either need to repair or correct the missing /dev/block/mmcblk0p2 partition. Any ideas if this is the issue and what would be the best way to correct this?
Any and all advice would be greatly appreciated!
Below is the system recovery for reference:

Bump - can anyone point me in the right direction?
Or would it be possible to flash my firmware in some other manual method, outside of using the usual recovery process? (i.e. applying the updated system folder and flashing the related boot.img found in the firmware I want to update to?)
