I disabled the reset function on the tiny85 to use it as digital pin and later I tried to reset it but it’s stuck on „Init programming”. It’s odd because I can restore mega328p chips. Also I was able...

Check quality of your +12V reset and +5V supply voltages slopes at rise and fall. If they are bad (timing is bad, rise or fall is long, it shows some riplle) then the patient chip can be in normal...

Hello, default fuses for AT90pwm1/2b/3b should be L=62, H=DF, E=F9. Can you paste here terminal log? Can you check your board with some other AVR chip? And you do not need this device to unlock...
