I was running the recent update to get the ring through to work and was reinstalling my back up from my storage card, but now my phone is stuck in the boot screen with the yellow logo......HELP!!!

FYI I have tried multiple hard resets and it still stays on the boot screen

try taking the battery out and waiting about 15 minutes or so and try to start again........................if this doesn't work, a trip to the Sprint store will be next or call Lockline if you have insurance.

Do you select yes to clear both the registry hive and the storage?

Put the phone in Bootloader mode and retry the flash.

Hold down the voice recorder and power button, and push the reset button on the bottom of the device to enter bootloader mode. Connect the USB cable and flash away.

I got this procedure from another site and have used it myself when flashing to 2.2 - it should work unless your 6700 is actually damaged in some way. Its very hard to actually brick a 6700 with a flash upgrade.
