Phone won’t boot.
Hello there. So my father was using the phone and suddenly it turned off. We tried to open it again but it wouldn’t. We tried every button combination but it will show the logo and stop. Sometimes it will flicker and glitch pixels too. Anyways, we bought a new battery but the problem still existed. After tries and tries removing the battery and pressing buttons we managed to get to a screen that warn us about a costume OS installation. We pressed continue but it froze. Again we remove the battery and tried again many times and we managed to get another screen that said FRP LOCKED. Now again it’s kinda hard to get those screens. Anyone that can help me fix this please?.
