Hello, if the mobile phone is dead now, it needs to be charged with the original charger for 30 minutes before it can be turned on. If there is enough power, please try to enter engineering mode to clean up the cache, and then restart. Method of clearing cache: When the phone is turned off, press and hold the power button and the volume reduction button at the same time to enter the engineering mode, and select the option of clearing cache through the volume button, and the system will automatically clear the cache for you. After clearing the cache, select Restart to see if it can start normally. If you can't enter the engineering mode? I suggest you take your mobile phone, warranty card and invoice to the local customer service center, and the staff will help you check your mobile phone and then help you. The address of the national customer service center is /service/network.

If you have any other questions, you can enter the OPPO enterprise platform to ask the customer service!
