Question about Samsung SCH-U450 Cell Phone

Open Question

First my phone was stuck in USB bootlock mode. I tried taking the battery out over and over and sometimes it would get out of bootlock, but when it did it kept spazzing and doing things by itself. Eventually the screen started to get darker than normal. Finally I went to Menu, settings, phone info, and Software update, so now the phone always turns on. But it still will randomly call "#963" or try to text it, or change the volume, and the screen is still really dark, barely visible.

SOURCE: screen is now white with the text --download started--, emergency @ usb.

i dont know what is happening, nothing happened to my phone to my knowledge, it just went to a white screen. on the white screen it says --download started-- blank then it says, emergency @ usb, then at the bottom of that screen it says, boothlock version: a870:zd09.1. i can turn the phone on, but it goes directly to this screen. i cannot turn it off, i have to remove the battery. i also cannot call or text or even see anything other than this white screen. i cannot receive calls or text either. what is wrong?

Take out the battery to unfreeze it, then Menu>Settings>Phone Info>Software Update>Check New. Repeat the Menu etc step till it doesn't find any more new software -- it may have to update an update.

Stuck on usb downlode mode


Take the battery out of your phone so it shuts down. put the battery back in but do not press the power button. plug in the usb cord to your charging input on your phone. next plug the usb end into a usb port on your computer. make sure your internet browser is open. phone should automatically turn on and reset itself. If it does not come back on then press the power button. If this also does not work then you will have to flash your phone or find someone that can

My lg rumor is stuck in usb mode and i dont know how to get it off


Hello,

To get your phone off usb mode,

First turn off your phone, remove the battery and reinstall it back.

If that does not work, the you can got through the menu, select the security settings, and restore the factory settings.

If that does not work, then it means you have to flash the phone.

it will automatically reset the phone.

Take care
