I have had the same issue since I reflashed, and I have flashed my phone lots of times. I have tried every possible combination. It's driving me nuts, I'm on holiday with a 500 pound camera. this has to be a bug.
I used the wifi hotspot to install a different kernel, but I couldnt uninstall as it was stuck in a loop, thus I had to flash. Any more ideas? Should I try and reflash the kernel?
