What GRE scanner model do you have? What is showing on the screen when you power it up?Is there any place to send these now ..I tried to update mine and now it appears to be in a update mode not letting me shut it off unless I pull the power.
That is a typical situation where the firmware update was applied incorrectly. It's still waiting for the update file.It's the 800 Model...... the screen says this below as soon as you put a battery in it without turning it on. I can't shut it off either
uP Boot Ver :F1.0
uP App Ver: NONE
CPU SW Upgrade:
Waiting for USB
Yep, that's about your only option if something truly needs repaired on an actual GRE labeled radio.
