And doesn't work anymore. Yesterday evening I had the charging cable on and instead of charging it only became less. Now, when the charging cable is closed, it flashes red briefly every 2 seconds. Turn on is not. I also tried the power button and up and down buttons. I also left it on the cable longer. Nothing goes. Thought it was probably due to the cable or the socket, so I bought a wireless charger. Put it on and it flashes but it doesn't go on. I have very important data on it and I don't care about the cell phone. What can I try next? Now in the crisis, I can't just get it anywhere. Everything to?! Thank you in advance and sorry for the spelling mistakes. I'm writing with an old replacement cell phone.

Lo

Have you tried the power button + volume up button at the same time?
