Verizon told me that maybe at the store they could possibly download the software back on to my phone......that's a big maybe. The tech told me that once it gets to this point, a lot of time it's too late. If they can it will happen, if they can't oh well, I'll get another phone and go on. I really like this phone and the version 2 from what I was told, won't do this. But I also know to back everything up.

My phone just blinks vcast now


I work for verizon-take your phone to a verizon store, have them swap it out for a new one. If your phone is under warranty you should be able to swap it out for a new one. If you are in contract the WARRANTY IS GOOD FOR THE LIFE OF THE CONTRACT. Call our Customer care line, don't go back to the store.

Will not boot up I believe the boot has been locked


what you need to do is take the phone to a mobile service center and have them fully service the phone, then reflash the firmware on the phone this will fix the issues.

Turn it on, all it does is vcast flashes off and on


Same thing here... got caught in the rain, and now it just goes on to the V-Cast screen and flashes.  Removing the battery does nothing.  Tried a blow dryer to the case (didnt disasemble) but this had no effect.  Any ideas? abkapner@yahoo.com

Vcast screen keeps repeating.


It's a software crash, and unfortunately it's unlikely even the technicians in your local Verizon store can fix it. They will almost definitely have to replace it.

The good news is that this is a warranty issue, so if the phone is less than one year old it shouldn't cost you a penny.

The bad news is that any data on the phone is most likely lost :(

Wet phone


Did you try taking out the battery and letting it dry. Depending on how wet it got, your battery may need to dry out or the phone is damaged. My friend dropped his in the shower, took 2 days for the battery to dry out and it was fine.

White Screen on u740


If it is a Verizon Wireless phone and you have bought it in the past year, it is covered under warrenty. When mine loads it will start with a white screen before it goes to my pic on the main page. Did you try setting the background on the main page, change the wallpaper and theme, if nothing works, like I said take it back if it is still under warrenty.

Your phone's .scr file is corrupted. Try this first....*228 and Send, wait for it to finish, the phone should power off and on by itself....then go into VCast. If this does not work, then go to the Verizon store and ask them to reflash the phone. If you tell them the problem, they should know what to do....
