Hi Nick,
Did anyone manage to backup the E2s firmware or hack it at all..?
So you're interested in reading the contents of the Samsung K9F6408U0C-TCB0 described at https://inputplus.co.uk/ralph/emailer/emailerplus.html#hardware-7 ? I'd expect that to be possible using the JTAG test points on the board, though I don't know if enrab's photos are available now his site has gone. https://inputplus.co.uk/ralph/emailer/emailerplus.html#jtag
