What can I do if my phone keeps rebooting or won't boot all the way to the Home screen?

When the phone is unable to fully boot to the Home screen or keeps rebooting, it may be having issues launching the operating system. In these cases, the screen may show a warning icon, such as a red triangle with an exclamation mark , or it may show the HTC or carrier splash screen but not proceed to the Home screen before rebooting. You can use one of three different button combinations to force the phone to restart the boot process. See How do I reboot the phone using hardware buttons? for details.

If the phone is still unable to boot to the Home screen, you may need to reset the phone to factory settings. Since the phone will not boot properly, the factory reset can only be performed using special commands outside of the device settings. See How do I perform a factory reset using hardware buttons? for details.

If the phone continues to experience problems after the factory reset or the reset cannot be completed, you can reinstall the software, which will also delete all content on the phone and install the latest software version. Please visit the Updates page to find the latest ROM for your phone.
