    @flopp Yeah I did try that one too.
    I will retry some stuff tomorrow and if that doesn't work (again) I will have to reburn the bootloader. Thought there might be some easy solution I overlooked.

      Something must have been damaged on that board. I was able to reburn the bootloader using and arduino UNO with the ISP sketch but I still can't update the sketch via serial. I build another board and that's working now.

        @LastSamurai when you connect the Pro Mini to FTDI, does it blink the led on 13? The standard boot loader should blink three times. If it doesn't blink, maybe it doesn't get power. I managed to damage the Vcc connection from the FTDI header on one of my Pro Minis, but if I power it through the Vcc pin on the side it works.

          FTDI are up to there old tricks again and trying to block counterfeit chips. I have a couple of nano's that I can no longer program on my windows 10 computer but will work on an old windows xp laptop.

            Shenanigans like that makes me happy to work with Linux. But if I had to buy it again, I'd use an ch340 based usb-ttl device just to avoid ftdi chips.
            Something like this: http://www.aliexpress.com/item/CTS-DTR-USB-Adapter-Pro-Mini-Download-cable-USB-to-RS232-TTL-Serial-ports-CH340-Replace/32236136728.html?ws_ab_test=searchweb201556_6,searchweb201602_5_505_506_503_504_301_10032_10020_502_10001_10002_10017_10005_10006_10003_10021_10004_10022_10018_10019,searchweb201603_2&btsid=dbfef4d9-1a89-4f88-9906-180148e01e92

              Thanks for your help guys. I know the problem with the FTDI drivers and I already switched back to an older version from 2013 which is working fine (although windows 10 sometimes replaced these with "better" drivers :angry: ).
              I'll try that power fix though.

                Did you solve the problem?

                I have the same error when I trying to upload any sketch to my pro mini.

                Tried two boards, and the first upload went well, but when I tried to upload a new sketch it wont work.

                  I had the same problem. But I blew something on the board when I forgot that I shouldn't connect the VCC of the FTDI while I had an external power source connected to the arduino as well. Apparently some Arduino's can't handle that ;-)

                    @LastSamurai
                    I made it!

                    Tried a lot of solutions that I found on google, and when I tried to sleep, then i found it.
                    I found this:
                    http://www.instructables.com/id/Uploading-sketch-to-Arduino-Pro-Mini-using-Arduino/?ALLSTEPS

                    It work from the beginning, so I think the serial adapter is the problem.

                    I hope this would help you all.
