I don't know if it is causing the AVRDUDE errors but it looks like the image (153K) is bigger than the available FLASH in the controller (about 120K). You'll need to delete/disable options until your image is under 120K and try again.

@Bob-the-Kuhn thats a intel hex file, it is a text representation of the bin. you must convert it back to binary to get its real size. @gromas with bootloader means that the image contains a bootloader, you need to use a AVRISP to program the device. As that is the only way you can write a new bootloader.
