@thelifeofmobile: Oppo A54 Won't Turn On? Red Battery Charging Error Fixed! Is your Oppo A54 not turning on and showing a red charging logo/error before shutting down? In this video, I show you how I diagnosed and fixed this issue step-by-step! When plugged into the charger, the phone showed the Oppo logo, flashed a red battery error 4 to 5 times, and turned off. After opening up the device, I found that the battery connector was disconnected. Watch how I safely opened the phone, fixed the battery connector, and brought it back to life! #OppoA54 #PhoneRepair #TechRepair #MobileRepair #DIYRepair
