Well, that's good, the screen is still working. If the phone won't turn on at all then it's time to take aggressive action. First, try booting into recovery mode one more time.
Ensure the R and SPACE keys are pressed down firmly, and no other keys are pressed. Then press the power button to turn it on, while holding those keys. If it still doesn't do anything different, then here's something a little more brutal you can do.
You can flash the Devour's SBF file onto the phone using RSDLite, which is about the same concept as formatting your computer's hard drives and reinstalling a fresh operating system. Use the SBF file CALAND_X_01.15.08P_MONSTER_01.sbf
and use the guide provided Using RSD Lite to flash an SBF file -- correctly - Droid Forum - Verizon Droid & the Motorola Droid Forum
. That guide is for the Droid, however, but to get your Devour into bootloader mode you take out the battery, hold keys "E" and "R", then plug the USB cable into your phone and computer. (Step 4)
Please note that if you flash the SBF file you will have to redo all
steps to root your phone again if root access is desired.
If something goes wrong and your phone is permanently bricked, go to a Verizon store and see if they'll just send you a new one. They did for me, even though my phone was rooted and wouldn't start up. Just say you tried to install the over-the-air update and it failed and showed you the blue bootloader screen.
If you have questions, post back here, I had to use RSDLite and the Devour SBF twice
