Try pulling the battery & SD card, power up without SD. Do a factory reset. Are you currently in an unlocked state with a fresh .22 RUU installed?
now I can not really answer, because that I have tried many options to fix this.

I also tried to flash original RUU_Vigor_VERIZON_WWE_2.01.605.11_Radio_RS_0.95.00 .1123r_3161E_9K_QMR_release_233635_signed.exe, but when I click the button to proceed and I get an error message stating it failed due to an invalid signature.
