SuperR Pusok what model GoPro is this? You repalced the battery? Checked the charger to make sure it works? Cleaned the chraging port with some isopropyl alcohol? Checked for bend/broken pins on the charger? This could be a bad charger, bad charging port, corrosion on the inside of your GoPro etc. So we need more information to at least getting started
