Fatal Error on BLU-806 and Some other devices.
We have some BLU-806 at a system.
Someday, I see the "Fatal error:04" on Lcd window at a BLU-806.
I turned off and on the issued Device, and it was good working.
and some month later, It appeared at another device. and I turned off and on. it worked well.
I see that message three or four times a year.
so I discomfort with that system. because I do not know why that message come out.
anyone know why Fatal error:04 displayed.
I wait for your reply.
