(TECH) Unable to falsh Adrunio IDE firmware

I had the same problem but after several trials an errors now it works - no reason why.

Maybe these advices help to avoid or overcome the problem:

  • install the drivers as admin.

  • be shure, that the battery has enough power.

  • run “\Arduino_IDE_for_RePhone-master\drivers\mtk\UninstallDriver.exe” to repair driver issues.

Good luck!
