I got a new phone and am trying to sell my old HTC desire C with beats audio. When I turn it on it says 'type password to decrypt storage' but I can't remember my password, any way I can overcome this? It has no SIM card either.
Power off your device and wait for 5-10 seconds until the device is fully switched off. Press and hold Volume Down button, then press the Power button to switch on your phone and release it, but keep holding the Volume Down button. └ This will boot your HTC Desire C into bootloader mode You’ll see a screen with option to boot into Recovery mode among several other options. Here, press Volume down once to navigate to RECOVERY, then press Power button to select it and boot into Recovery mode. └ In Bootloader and Recovery mode, use Volume buttons to navigate Up and Down between options and use Power button to select an option.
You should have an option to wipe device. Unfortunately, if you forget your password, all of your data is just gibberish.
