Ok, so here's the command I'm using to push it to the phone:
dd if=/sdcard/lucid.img of=/dev/block/mmcblk0p26
(I renamed the file for brevity)
Doesn't seem to do much. Even when I wipe the phone in CWM and reboot, start from scratch and run that command, it still comes up that I need to install the OTA and nothing has changed. Not sure if maybe I need to be writing to a different location or what.
