I reflashed using the MK2 TAR (from http://forum.xda-developers.com/show....php?t=2621279). That seemed to get data working and fixed the error but wifi doesn't really work. After first boot/setup, when it asks for wifi network/password, wifi seems to work and shows available wifi networks like expected. I select my network and enter password, then it just hangs for a bit then goes back to the wifi enable screen, with the on/off toggle not green and the area below just says "turning on". Rebooting doesn't change anything. Can't turn on after that. After a hard reset, I am able to do the setup again, but same thing... works to enter password but then never again.
Seems like the options to try are to reflash a kernel or try a 4.3 ROM, but I don't want to take a few steps back after the reflash got the data working again (at least it can be used as a phone again). Also, my main goal is obviously just getting it working like normal, but I also don't want to lose any future flashing because I was rash and did something I shouldn't have.
Thanks for any help you can provide.
