Chosen Solution

Hi! I ordered an iFixit essential electronics toolkit from the EU store and a new frame and screen for my Honor 8 Lite (P8 2017). Once I finally got them, I replaced the broken screen and bent frame, but once reassembling everything and booting the device, I get a black screen with EMUI logo requesting me to reboot the system, doing a factory reset or wiping the cache. I tried factory resetting and wiping the cache, but it still reboots to the very same screen. I’ve re-seated all connections twice now and I still have the problem. What I am more curious about is why it does this, after all the only part it could know has been replaced is the screen. Please help!

Check the power switch first sometime this may causes such issues.If same then firmware upgrade the phone. Hope this may help you.
