New firmware solved my problem of being stuck at start-up screen. Interestingly, using an older SD card (256MB) freshly formatted and only with the bin file on it will not update the printer. I emptied the 8GB card that came with the printer and that did work. Hopefully it will work for Sonics99 too!
Unfortunately, I am stuck again at the auto-leveling. I will look at the forum threads and see if I can solve that through that route first.
