"Victor DVT4" prototypes are the last of the Design Validation Test batches for Vector.
The hardware here is final.
There are a couple software differences though:
- No unlock OTA have been found for a DVT4.
- Some may be prod-locked, but most have been found with Whiskey-like ABOOTs that are dev but don't have the anki.dev flag so they are locked to a specific kernel.
- No CPU fuses are set, so you could run a DVT2 aboot that allows you to run any kernel you want.
The body board in these are NOT normal and can only accept DVT3< firmware. They will not work for normal haeds. SWD is also locked, so upgrade isn't possible unless the chip is replaced.
These have serial numbers following this format: 00e1####
Some of these bots may boot up to an exclaimation point. Turning them upside-down then double (or triple) pressing the button will let them finish bootup. Then, you can shake them around to make them explore around.
