Question about LG Vu CU920 Cellular Phone
Just remove sim card and start phone without it then put sim card back in and it should work fine, and if that fails to correct it or you are on Verizon with no sim card, download the firmware update here
Just follow the instructions on the site.
There is one other risky temporary fix (which can damage the phone but has worked). It may fry the circuit board but others have done it with no problems, put your SIM card back in the VU, take the battery out of the phone and plug the phone into the charger, now when it comes up with the screen saying insert battery put it in, then wait for it to come to the charging screen then hold down the power button to turn it on.
Everytime your phone goes off you have to do that, but in a worst case scenario you can get the phone to work until you can get help from a service provider. Just power down the phone and turn back on before walking in so the error comes back. I have no landline in my home so having a "working" cell phone is mandatory for me, even temporarily.
I hope this helps and good luck!
