The Nokia C100 is a great phone, but sometimes it can get a bit wonky and need a good hard reset.
To start, you'll need to find the correct key combination to initiate the reset process. According to the user manual, this involves pressing and holding the Volume Down and Power buttons simultaneously for at least 10 seconds.
Pressing these buttons will trigger a forced reboot, which can help resolve minor issues. However, if the problem persists, you may need to perform a more extensive reset.
The phone's settings allow you to perform a factory reset, which will erase all data and restore the device to its original state.

Wiping Data
To wipe data on your Nokia C100, you'll need to perform a hard reset. This will erase all content stored on the device, so make a backup copy of your data before proceeding and unlink the Google account.
The hard reset process can be accessed through the recovery mode, which can be initiated by simultaneously pressing the power key and the volume key down for a few seconds. On some devices, the combination may be the power key and the volume key up.
When the Nokia logo is displayed, release the buttons. You'll then need to move through the menu with the volume up and volume down keys until you reach the option "Wipe data/factory reset" and press the power button to access it.
A warning message will appear, and you'll need to use the Volume Up and Volume Down keys to select the "Yes" option and press the Power button to activate the option.
This will result in the formatting and deletion of all data from the Nokia C100, returning it to its factory state. After a few seconds, you'll need to restart the device by moving to the option "Reboot system now" and pressing the power button.
Keep in mind that the procedure may be slightly different depending on the country, model, and firmware updates of the Nokia C100.
