Re: Kyocera DuraForce stuck on restart screen. Help
I have the same model. I am currently stuck on the "ATT" icon screen with white background. This screen is part of the reboot scenario when one restarts the phone. It will sound the swoosh sound and then just stay on the ATT logo.....I have tried numerous times to " hold on/off button and volume up at same time" only to have it reboot to the ATT screen again.
I didnt drop it or anything just woke up to it. I am at wits end trying to figure it out. I have evendrained the power to try to see if that would work when recharging.....nope!
Incursio, have you found a fix to your cell yet? If so I would love to read about it. Thanks!
