My original SD card that came pre-setup finally carked it after almost 4 years of solid use. So I've purchased a replacement (32GB Kingston, Class 10), but I'm struggling to get it to work with the exact camera I have. It doesn't help that I don't actually know what firmware is currently running on the camera nor do I know what version camera it is (English, Korean, etc). I've run the SD formatter on the SD card using the 'overwrite' function and it completed that fine. I've lost count of the different firmware versions I've tried, and the different configurations of changing the config.ini to English & Korea. Some results I've had: Firmware 1.38E, config set to Korea - version incompatabile repeated in English voice. Firmware 1.38E, config set to English - Korean voiceover says 1 sentence and device flashes blue for a bit and restarts, GPS LED lights up, restarts again, then Korean voice repeats the same sentence over and over (from my testing and guessing, it's saying version mismatch). Firmware 1.40E, both English and Korea - instant version mismatch. Basically, no matter what firmware or language setting, the camera doesn't startup properly. Googling for a guide brings up a complete ****load of different ways, and not knowing what firmware is currently installed doesn't assist... Does anyone know exactly how these cameras work and what they are checking for at bootup? Is there a 'surefire' set of steps I could do to reset or start the device from scratch?
