Sounds like you need to restore the stock ROM, just download it and flash using flash tool and your device will work again.

It appears the PureX audio may have corrupted the ROM and has prevent it from loading

Hope I could help

I'd like to share my experience about, I had the same problem, what i do is to press power button and connect the phone to the computer (befere I tried to flash it with flashtools and I couldn't get the phone to enter to flashmode) a icon of the battery will appear, now start flashtool software (you should have the firmware downloaded previously) and follow all steps for reinstall android, this time flashtools recognize your phone.

I hope have helped, and sorry for my english I'm not english speaker.
