Update to my earlier issue - The bootloader screen states "FASTBOOT MODE - NO BOOT OR RECOVERY IMG". I assume this is the issue and it what is causing the boot loop. How do I flash a boot or recovery image? I've downloaded the Android 4.0.2 (ICL53F) files from google code, but following the instructions in the OP gives a file not found error.
Did you download the files linked in the OP?
You need to unlock the bootloader in step one, and then in step two you flash superboot.
i think that's where you're at right?
so, did you go thru with all the steps in the op with the designated files that are linked there?
