Regardless of the PIN code associated with the SIM card, Android offers several lock solutions to protect access to a mobile device and, more specifically, to the personal data it contains. Solutions that are usually implemented during initial setup, but are also entirely possible to activate or modify later. On recent models, you can usually use a biometric solution (fingerprint reading or facial recognition with the selfie camera). But on all models, old and new, it is possible to define a numeric code (PIN code) or a lock pattern (a path to connect dots on the screen).
Unfortunately, if this unlock code or pattern is forgotten, and if a biometric alternative has not been defined, the mobile is locked and the user no longer has access to anything. Logical, since it is a security measure intended to prohibit the use of the phone or tablet by a stranger, in the event of theft in particular. However, there are solutions to unlock the device. But the method and, above all, the result vary depending on the version of Android.
In fact, Google has tightened Android’s security with each new version by making it more complex and even completely removing the options to bypass a forgotten unlock code or pattern. Thus, if you have an old mobile, you can easily unlock it without losing anything. But if you use a recent model, there will be no other solution than to reset it by deleting all its content…
If you have an old device running an older version of Android (4.4 or earlier), you can easily unlock it when you forgot the unlock code or pattern.
On the unlock screen, enter a passcode or pattern (any!) five times in a row. An alert appears indicating that you tried to unlock the device with the wrong passcode or wrong pattern. The screen then locks for thirty seconds.
After this time, a new option is displayed. Press “Forgot code?” »
or “Forgot the pattern? ” depending on the case. A screen appears to sign in to your Google account associated with the device. Enter the email address and password for the account. Your smartphone is normally unlocked.
Then go back to your mobile device settings to set up a new code or pattern lock.
Android 5.0 or higher
Since Android 5.0, Google has drastically tightened security by removing the ability to reset a forgotten unlock code or pattern. If you have locked your smartphone, there is no other solution than to reset it completely to restore it to the factory state, with all the default settings, like the first day. The manipulation can be done in two ways: the first using the Find my device service that allows you to remotely wipe a mobile, the second by accessing the hidden Android reset menu accessible through a small operation.
– With the location service: obviously it cannot be manipulated with a locked device! Grab a computer, tablet, or other phone, launch a web browser, then go to the Find My Device service and sign in to the same Google account you used on the locked device. This is found automatically. Then click Wipe device and confirm to wipe device data.
To start the process of resetting your device to its factory settings, you need to confirm your choice one last time by entering your Google account password. Then press Delete in the dialog that appears to confirm the permanent deletion of data from the device. To use it again, you will have to reconfigure the mobile as if it were new, fresh out of its box.
– With the restoration menu: since the mobile is locked by a code or a pattern that we do not remember, obviously we cannot reset it in the usual way, from the Android settings. But you can get past a hidden restore menu, accessible at startup through the physical power and volume buttons.
First make sure the phone battery is fully charged and then turn off the phone. Then simultaneously press the Power button and the Volume + or Volume – button (depending on the model). It shows the Android boot menu, the bootloader, in the jargon. Its appearance and option labels may vary depending on the device manufacturer, but you should find it easily, even if everything is in English. To navigate through the menus, use the Volume + and Volume – buttons. Go to the Recovery Mode option that is highlighted. To confirm your selection, press the power button.
Once in Recovery mode, go to the Wipe data/Factory Reset option with the Volume + and Volume – buttons and confirm with the Power button. A message Delete all user data is displayed (usually in red). Choose Yes or Factory data reset using Volume + and Volume – buttons and then confirm with Power button. At the bottom of the screen, a Data Wipe Complete message is displayed confirming the mobile reset.
Then select the menu Reboot system now using the volume buttons and validate with the Power button. Your mobile restarts free of data, as when it left the factory. All you have to do is completely reconfigure it, just like the first day. However, you can save time by using your Google account to automatically retrieve apps and lots of personal data (contacts, calendar, etc.).
