Have you been able to flash other drivers before this?

[Marios]

No, this is my first use of the USBasp programmer.

Same error when trying to flash using my phone

OK. I am not expert enough to be of much help. I have to refer to my notes every time. There could be many reasons. Let’s wait and see who else can help. Best of luck with this.

Thank you so much MtnDon,

I don’t know what fixed it, i just re-seated the clip and added “:a” at the end of flashing command… and it worked

the weird thing is when the flashlight is off the green led inside the push button is ON and vise versa… now i have to turn the battery cap to disconnect the battery and make the switch led off… weird.
