Hi @imbuildr
If data is not important, you can consider this
Master reset with hardware keys
A master reset restores the original factory settings and may delete your personal data on the internal storage, such as downloads, ringtones, images, apps, contacts, and Visual Voicemail. It does not delete data stored on the SIM card or SD card. If the device menus are frozen or unresponsive, you can master reset using hardware keys.
# Back up data on the internal memory.
# With the device turned off, press and hold the '''Volume Up''' and '''Power''' buttons until the ZTE logo screen appears, then release.
# Press the '''Volume down''' button to highlight '''wipe data/factory reset'''.
# Press the '''Power''' button to select.
# Press the '''Volume down''' button repeatedly until '''Yes -- delete all user data''' is highlighted.
# Press the '''Power''' button to select.
# Wait as the device resets.
