well after flashing frozen rom this morning on 100% battery, installed fine, booted up, rebooted as suggested. and now here's the interesting part. once it was in the process of rebooting, splash screen came up and everything just goes black. won't power back on, won't charge, isn't even recognized by laptop when plugged in, can't even get to the bootloader. i do beleive i've got a brick on my hands :/ and it's off to the sprint store tomorrow.
