Uaaahhh!
I just finished it and now I’ll have to take it apart again for the update 
BTW, in my KIT the front panel didn’t match the LCD. The hole was too small. I fixed it, but did anybody else have that problem ?
Edit:
Just an important note: the 10pin header on the PCB is NOT standard 10pin ISP layout and will short 5V / GND if you connect a programmer.
Edit 2:
I would not update the firmware. Since my update the scope shows some strange characters for SEC/DIV. Timebase is completely borked. Only thing that still works is frequency measurement and V/DIV. Going back to the old firmware (downloaded from jyetech site) doesn’t fix that 
Edit 3:
It seems that after the update to -080 the device was in some kind of illegal state that wasn’t fixed by going back to -070. Pressing the +/- buttons in SEC/DIV in one direction finally showed good stuff. This also works with -080. After that the strange characters and timebase error was gone. Also note that the ADC doesn’t get power when J1 is not connected! If your programmer supplies power, only the CPU and the display runs, but not the ADC.
Edit 4:
I was able to trigger the illegal state of the scope by using the new save to eeprom / read from eeprom feature. Definitely going back to -070 now.
Edit 5:
The fix only lasts till reboot, so I think its a firmware problem, maybe buffer overflow or whatever. Could anybody download the -070 firmware from a working device with avrdude and post that ? I’m not sure if the firmware on the jaytech site is OK. Should have made a backup. Darn.
Edit 6:
The eeprom is not erased when flashing the chip, maybe some bad data from the old firmware was left ???
