Once the board is closed you can only boot from signed images. If the signed image is not working (hanging during relocation for instance), then you can always boot from a new one. All the interfaces: SD-card, UART, USB are still usable. I have tried many u-boot versions on my closed board until I had something working. So, no you do not end-up with a brick unless you cannot sign your image properly anymore. Or maybe I missed your point? Thanks, Mathieu
