Switching Off and On the Device and Bluetooth

It is the easiest and simplest troubleshooting process for any device whether an iPhone or an android, where the user can try switching off the device such as a speaker, and then switch it on to fix any minor issue if present in the device software.

For an iPhone, just long-press the power button and slide the power off appearing on iPhone’s screen. This way the phone is switched off. Now wait for at least 30 seconds and then again press the power button to switch on the iPhone. After the phone switches on, try getting connected to the device.

Similarly, for an android phone or device, hold and long-press the power button and swipe up the screen to start the phone again. Once the phone is switched off and on, it will ask the user’s password or pin. Enter the same and try connecting to the device again. If the problem persists, try switching off and on the Bluetooth connection. Go to ‘Settings’ select ‘Bluetooth’ and slide the On/Off button. When the Bluetooth is off, the selector switch will turn gray, once the Bluetooth is on, it will turn blue. Once the Bluetooth is turned off and on, try reconnecting to the device and see if the problem is resolved or not.

Switching Off and On the Device Pairing Mode

There can be many times the device refuses to connect due to some minor software issues. However, it can be resolved by turning on and off and again on the device pairing mode. This is also another simple troubleshooting method that will reconnect to the lost Bluetooth device without causing any major issues.
Usually, most Bluetooth devices have a toggle or a switch or a button to connect to any other Bluetooth device. Find the toggle or switch or the button on the Bluetooth speaker, headphone, or earbuds and switch off the pairing and wait for at least 30 seconds and then switch it on again.

Is DFU Restore a solution for iPhones?

For iPhone users, if none of the above solutions helps in reconnecting to the forgotten device, the user will need an in-depth restoration of the phone. DFU restore or Device Firmware Update restore follows an intensive restoration process that requires data backup before starting the process. The user can back up all the data on iTunes or iCloud or any other platform of their choice.

The DFU mode allows iPhone users to get back all the factory settings and get connected again to all the Bluetooth devices that have been forgotten.

Follow the steps to get started:

  • Start with taking the backup. Connect the phone to any computer. It does not matter if the phone is on or off. Open iTunes in PC or MacOS Mojave 10.14. In the case of macOS Catalina 10.15 or newer, open Finder.
  • Now in the case of the iPhone 6S or below, press the Sleep/Wake button and home button together at the same time. In the case of the iPhone7, press the Sleep/Wake button along with the volume down button. The iPhone will appear on Finder or iTunes on the computer.
  • When iPhone is visible on Finder/iTunes, release the buttons. The screen will turn black. Now restore the phone through iTunes or Finder. If the display doesn’t turn black, the process has to be done again.
  • For iPhone 8 or above, the phone can be restored in DFU mode. For that, quickly press and release the phone’s volume up button first and then the volume down button. After this long press, the phone’s side button till the phone display turns black.
  • Once the display turns black, long-press the volume down button and side button together. After 5 seconds release just the side button. When the phone is visible on Finder or iTunes, release the volume down button too. Don’t keep the volume down button pressed for too long. The Apple logo will appear on the display and the process has to start from scratch.
  • The appearance of the iPhone on Finder or iTunes signifies that the iPhone is now in DFU mode.

It is to be noted that the DFU mode deletes all the data on the phone’s hardware or software and starts the phone all over again. Since the phone is already damaged, would it be wise to damage it more with DFU mode?

Factory Data Reset- a last resort for Android

If everything else is tried still the Android device is unable to connect to the forgotten device, consider a factory reset as the last option. Bearing in mind that there will be a data loss while doing factory reset so it is recommended to have a backup.

For factory reset, go to ‘Settings’ and select ‘System’. Under ‘System’, click on the ‘Backup and Restore’ option. Select ‘SD card’ for backup and start the factory reset. Now again open ‘Settings’ and select ‘System’. Select ‘Reset Options’ from the list of options and then click ‘Factory Data Reset’.

After selecting the Factory Data Reset, the user has to confirm by entering their device password to start the process. The reset will take few minutes to complete.
