Blinking blue box with lock symbol on screen

Try with the Mitsubishi remote the soft restart, set on Menu,1,2,3, and enter.

Cold start and repeat. Format the drive. "blue invent screen"? Is the HDD led blinking? Are you using a disk? or recovery partition?

Look to the owner manual if you have it as it will likely have the answer you need--if no manual Google the model number with "manual" to try to locate the owner manual---if get or have it read it carefully as it sounds like to me the parental lock is on or something similar to it.

Try dumping the RAM. To do this press the power button and then hold "Command, Option, P, R" before the gray screen appears. Then the computer will 'bing' and restart. Wait until it has 'binged' twice then let go.

sounds like the ram is fauly

Have the vehicle check for DTC'S diagnostic trouble code's . Qualified repair shop !

The light is pressure sensitive. Press it and see if it turns blue. If that doesn't fix your problem then the adapter might be disabled. To check that go into your Network and Sharing center and on the left side of the screen click on manage network connections. There should not be an X on wireless network connection, if there is then right click on it and choose enable.

Generally rectangular box appears when you are in Roaming. After doing the Hardreset still if you are getting rectangular box in your handheld kindly walk into the nearest service center.
A hard reset involves physically removing the battery from the smartphone and then reinserting it. To perform a hard reset, complete the following steps:
1) Remove the battery cover from the back of the BlackBerry smartphone.
2) Remove the battery, and then reinsert it after a few seconds.
3) Replace the battery cover.
I hope I was able to help you.
