Installed beats audio drivers. Didn't like them and wanted to go back to Volume +. Found an uninstall program for the beats audio and ran it. Now phone won't go past the boot screen. I have CWM installed but no backup to flash. I tried to mount the SD card in CWM so I could copy over a ROM to recover with and get an error message saying "E:Unable to open ums lunfile (No such file or directory)." I then tried putting the SD card in a reader on my PC but it's not recognized. I'm guessing that's because it's formatted for Android? Any other ideas before I pack it up and send it back to ZTE?
