Dead poll mode means the V2 is waiting for you to flash in the firmware.
You need to use V8 HAPI to flash, not the EFILive Firmware Programmer. What bootblock do you have? Open up V8 Scan & Tune, then click the V2 icon that appears next to the windows clock. Click F6 Firmware, then if you need to update the bootblock do that, then program the firmware.
What firmware version did you upgrade from...?
If it was 2.4.xx then there's a specific procedure for doing this.
