I've reproduced this bug, and the entire codeplug is definitely being obliterated during installation. This was not caused by an incoming packet or frame collision.

Looking a deeper, it seems that the VHF codeplug is much smaller, only 1MB instead of 16MB. Thus there is no room for the DMR MARC database, and we ought to avoid flashing the database, as the erasure will take out the original image.

That seems to have fixed it.
Running the update for a little while, then abandoning it gives me this message.

We should add a USB command to query the SPI Flash's extra parameters over USB, as silently failing is a bit awkward to the user.

Given that this issue has been duplicated at #69, #78, #117, #128, and #131, it's probably time that we did something to properly close it.
I suggest that we either find a gap in the codeplug's lower 256K which is unused, or we compromise by putting the menu settings at 0xEBFC, where 72 bytes are available overlapping the very last two contacts.
Close this issue when menu settings are stored somewhere on VHF devices.
