Thanks Tautech
That is just the problem the solution with the scoop button is not working.
Tested the trick for more then 30 times.
While pushing the scoop button gives only a Bleeb after more than 25 seconds pulse pushing the scoop button.
And i can only get it in the meter mode.
When pulse pushing the METER button it gives a Bleeb and after the Bleeb the meter screen appears.
When in the meter mode no user menu is available
If I push the scoop button the SHS806 freezes and power down is the only way getting out the freeze status.
So I hope flashing the software will fix the problem.
Do you mean this chip NOR memory? And his Jtag connection?
