K800i F4# error - Esato archive

Posted by kyoung1988
Hi, I don't know whats wrong with my phone but everything is written like f4:####. It started to happen when i turn off my phone on the plane and then turn it back on when i landed. I did not installed anything new on my phone. This just happen out of no where. I turned off my phone and took out my sim card and it didnt seem to work.
