just wired up my u310bt, and have had some trouble getting the firmware flashed so far. originally i was getting the "open os cks" error, and after determining that my partition table on my sd card was wrong, i formatted everything up and got the update on it. now the screen stays at "updating image." its been about 30 minutes so far, and no progress. is this normal? and if not, is there a way to format the device completely and start from scratch? as far as testmode, i dont understand how to access it yet. is testmode accessible without a working windows image? ill keep reading for now, any help would be deeply appreciated.

ok, so now im reading something about some sort of uboot mode? is there a way to get to the menu from the front panel or would i have to tap into the uart or jtag?
