Greetings to all. I have a problem. I have THETU SC. I can’t charge, I tried the original cable, non-original cables, charging from a PC, but also from the wall. He doesn’t react at all. The only thing he reacts with is POWERBANK. It flashes red, you can also take a picture of the trigger. As soon as I disconnect from POWERBANK, it switches off. I tried to change the battery, but it behaves exactly the same. Does anyone have a tip on how to do this?
