    so I bougt a tinyG and wanted to test tgFX and discovered that I needed a newer fw to test it, said and done, tried to flash with avrdude via USB and it cant verify the hex, I get:

    C:\tools\avr\bin>avrdude -p x192a3 -c avr109 -b 115200 -P COM3 -U flash:w:tinyg.
    hex

    Connecting to programmer: .
    Found programmer: Id = "XBoot++"; type = S
    Software Version = 1.7; No Hardware Version given.
    Programmer supports auto addr increment.
    Programmer supports buffered memory access with buffersize=512 bytes.

    Programmer supports the following devices:

    avrdude done. Thank you.`
    So after a few tries it only went into bootloader mode and wont start tinyG, connected it to my AVRISP mkII according to instructions(lockbits issue) but the Atmelstudio(6.x) tells me the lockbits where correct, reflased the xboot.hex and it looks fine, downloaded the latest tinyG and trie to flash it and atelstudio says:
    `Unable to parse objectfile C:\Users\selektha\Desktop\tinyg.hex: Unsupported format.

    Timestamp: 2013-07-05 11:10:10.044
    Severity: ERROR

    StatusCode: 131106
    ModuleName: TCF command: Modules:add failed.

    Unable to parse objectfile C:\Users\selektha\Desktop\tinyg.hex: Unsupported format.

    I have tried all tinyG.hex I can find on the Github and noone works(xboot.hex works fine to flash). And if I understand everything I should use the one in debug/ for atmelstudio6.1.

    So any idee how I can get my new and fine TinyG to work again? =)
    Sorry if I am unclear but im 100% newbee on this but like to tinker(danger danger! 😉 )

    Well.. I am not sure. See your board had the bootloader loaded on it. All you needed to do was flash via avrdude the tinyg.hex file. I am not sure what “state” your board is in now since you reflashed the bootloader. Unless you changed any “fuses” you should be ok if your reloaded the bootloader.

    That being said… save that file like told you how.. then hit “reset” (led should be flashing) then hit enter with the whole command line that was give via the instructions.

    If you are still having issues shoot me an email at riley &nospace& porter @ gmail.com and I can setup a google hangout or cell phone call to help you out. I we are hackers too I totally get trying to mess with stuff

    PS
    To put your mind to rest. Nothing you did should have “bricked” your tinyg. And being that you have an MKII you are gold. This is a speed bump in your road to CNC awesomeness.

    Just wanted to say that it now works again with the original master branch TinyG version, but I cant get the dev version to work so I havnt been able to test it yet, the problem was that the files got corupted when I downloaded them.
