My phone was locking up during the download, After about thirty minutes I pulled the battery and restarted. The download resumed but locked again. I removed the battery and tried again but this time I was caught in a boot loop.
Did a hard reset but the phone locked again during download....crap!!!!
Another battery pull but this time with the battery out I held the power button down for thirty seconds. I put the the battery back in, did a second hard reset.
After I finished setup I turned off wifi and sync before the ota download started again and this time i updated without a hitch. YAY!!!!!!
During the last two times the phone was locking up when the ota was downloading and wifi and sync were kicking on at the same time.....so far all is good.
