First diagnostic test should be the SD card. Use h2testw freeware
LINK with a freshly formatted card doing a full overwrite test (Link in German but program opens with an English option). If that shows all is well, then format the card to FAT32 in your PC. Note that Windows may not let you do this on cards bigger than 32GB.In that case use any card-formatting freeware which offers this. Put card in cam and power up. If it doesn't 'boot loop' then format the card in the cam. If this doesn't work correctly now, then the next step is:
Power the cam without the card and use the reset button with a paperclip via the small round hole on the side of the cam (press and hold a few seconds then release, you can feel it 'click' when depressed). Now insert card, power up, and test for function. If that doesn't work:
Try running the cam with a wall-powered phone charger, and if that doesn't work, reload the firmware. SpyTec should have the correct firmware for your cam. If vthey don't someone here probably will. (Alternative firmwares exist for most G1W series cams).
This should get you going good as new but if it doesn't or if you have any more questions just jump in here and ask.
