OPPO F21s Pro 4G Won't Turn On

OPPO F21s Pro 4G

Modern smartphones can malfunction even with the most careful of handling. They arise most often due to violations in the functioning of the operating system, but physical damage can also cause the malfunction. If the phone does not turn on, there is no need to rush to the maintenance center right away. First, you should follow a few simple and safe steps that can help restore your favorite device.

Why Won’t OPPO F21s Pro 4G Turn On

There are many possible reasons for the disruption of the stable operation of the device; often problems arise during everyday use. According to experts and representatives of device manufacturing companies, power-on failures may be associated with the following events:

  • after updating the operating system, some system files were installed with errors;
  • the device stopped booting up due to viruses that came with applications not installed straight from the Play Market;
  • after dropping the device on a hard surface, the display or battery cable became disconnected;
  • the USB port is clogged, or moisture has caused minor but harmful rust spots on the contacts.

It should be noted right away that it is not an easy task to handle physical damage on your own. When attempting repairs yourself, you can inadvertently disrupt some of the connections, thereby making the smartphone unrepairable. If the methods proposed below do not lead to a positive result, it is recommended to contact a verified MC for diagnostics and repair.

Force Restart OPPO F21s Pro 4G

First, let's look at several methods using Recovery mode. You can boot up the Recovery if the device is charged by more than 15%. At the same time, by connecting the charger, you can make sure that the screen is intact and that the USB port is working as intended.

Then, if the phone responded to the charging connection and displayed the info concerning the process of replenishing the battery, you can proceed to the following actions:

  1. Simultaneously hold down the power and volume up buttons. Hold them this way until the phone vibrates. The boot splash screen will appear and vibration will follow, after which the power button can be released. Important note: sometimes the combination works with the volume down button, but not the up button.
  2. In the newly opened menu select the "Reboot to system" button (in some versions the option is called "Reboot system now").

The device should immediately proceed to the reboot, followed by a regular Android boot-up. By the way, if the device does not charge, it is recommended to try other USB cables and chargers. It is possible that the issue lies with them, and the phone is simply discharged.

Resetting to Factory Settings

After performing the steps described above, several scenarios are possible. In addition to the usual rebooting and boot-up of the device, the phone may turn off or freeze up on the screen saver. You should not be too upset about this fact, as the steps done helped to make sure that a number of important functions and systems are working properly.

Rebooting via Recovery is an option suitable for situations in which the firmware suffered from minor glitches that were eliminated on their own. If the violation in the operating system is much more serious (for example, after flashing the firmware with errors), then you will have to reset it to the factory settings. It is important to note that this will delete all files from the device's storage, including photos, videos and music.

  1. Open up Recovery, as in the steps described above.
  2. Select Wipe Data/Factory Reset.

The device should reboot. The rebooting process can last much longer than usual (up to 10-15 minutes), after which you will have to perform the initial setup.

Additional Methods

What if the steps described above did not help? If the device suddenly turned off, stopped responding to pressing the power button or charging, then most likely the problem lies in physical damage. If you dropped the device or it got into the water, then you should contact the maintenance center for diagnostics. Another likely cause is battery failure. The main symptom is a rapid discharge from 100 to 0 percent until a malfunction itself is detected. When using smartphones with removable batteries, you can try to buy a similar one and simply replace it. If the case is one-piece, then it will not be possible to do so without the help of maintenance experts.
