Samsung SCH-U740 Double-Flip will start to start up but loading bar never finishes it just freezes

Sounds like your problem could be a result of a MAJOR software trojan.

You start by taking the battery out, wait 30 seconds and replace battery. Turn on the device again to see if if will boot up correctly. (Note: If this does work it is merely a temporary fix)

I would check with your carrier/and or nearest store for service/repair options. Your device may need a software update or even a hard-reset to set device back to factory defaults.

Hope this helps! Thanks.

Have you tried taking the battery out and powering on the phone just using the power cord plugged into the wall?

My samsung SCH-U740 will not power up, just sits and vibrates.

I think your only options are to have the phone refurbished or replaced. The SCH-U740 is extremely sensitive to moisture.
