Hello, try this.
Remove any case or gel skin from the phone. If the case is pressing on the Menu key, it can cause it to load into Safe Mode.
Remove the battery and SIM card (if present) from the phone.
Wait at least 30 seconds.
Press each of the keys and buttons several times, to make sure none of them are stuck.
With the battery still out of the phone, plug the phone into its wall charger.
Place the battery and SIM card back into the computer.
Turn the phone back on. While the phone is starting up, do not press any keys or buttons.
