Restarting problem or looping

There are a few possible reasons why your LG Env3 is only displaying the Verizon logo:

1. The phone is stuck in a boot loop: This can happen if the phone's software becomes corrupt, causing the phone to continuously reboot and display the Verizon logo.
2. The phone is stuck in a firmware update: If the phone was in the middle of a firmware update and the update failed, it may be stuck in a loop and only display the Verizon logo.
3. The phone has a hardware issue: If the phone's hardware has become damaged or malfunctioning, it may only be able to display the Verizon logo.
4. The phone is locked: If the phone is locked with a passcode or pattern and you've tried to enter it multiple times, it may display the Verizon logo.

If you're unable to fix the problem by yourself, the best solution would be to contact the manufacturer or the carrier to get the phone checked.
It is also possible that the phone was previously owned by someone else, it may be locked to a carrier and the only option is to contact the carrier and ask for assistance

you have to have it looked at sounds like the fone had developed a fault

Go to badcaps.com because a bad capacitor on the powder supply board will cause this. There can be other reasons, but all involve taking that Sony apart.

It might stop it booting in a loop, if it wont help you need to restore the phone and jailbreak it again

WHAT UR MODEL CONTACT UR SERVICE CENTER IS BEST.............

you have to hard reset it. Remove any software that you just install.

If your Treo loops or freezes during a soft reset, a system reset may help. Performing a system reset allows you to get out of an endless loop in order to uninstall a third-party application causing the looping: 1. Press the Battery Door Release button and slide the battery door downward to remove it from your Treo. 2. While pressing and holding Up , use the tip of the stylus to gently press the reset button on the back of your Treo. 3. When the Palm Powered logo appears, release Up . 4. Delete the third-party application that you suspect is causing the problem. 5. Perform a soft reset. The wireless features of your phone are not available until you complete this step. Good luck!
