Nextbase 322GW support?

[d687r02j8g]

I own a bricked Nextbase 322GW due to a failed firmware update. I found this repository and was hoping that @evilwombat might be able to assist with the Nextbase device.

Upon starting the device with the Nextbase button pressed, my laptop recognizes it as:

Bus 003 Device 015: ID 4255:000a GoPro A12

I am wondering if it's feasible to use the firmware files provided by Nextbase to recover the device.

Firmware files can be found here:

• Nextbase Support: 322GW Dash Cam Support
• Firmware Download Link: NBDVR322GWA-R23.7.zip

There are two files in the firmware:

1. FW322GWA.bin (51M)
2. LD322GWA.bin (1.2M)

Running binwalk on FW322GWA.bin produces extensive output, including shell scripts and various other elements. The initial lines of the output are as follows:

Binwalk for LD322GWA.bin is relatively short:

I'm open to trying out and experimenting with potential solutions if someone could guide me in the right direction.
