I am running 4.2.2. on a Moto X that was rooted using PwnMyMoto. I am trying to upgrade to 4.4. and I am having no luck doing so. I have read in all the other forums that the phone must be unrooted to load the update. I have attempted all the tools and methods as well as watched the Youtube videos all to no success. RsdLite does not recognize my device and I have the current Motorola Device Manager. I tried the MotoX Tool Kit and that doesn't work. My computer is running Windows 8 and it recognizes that my phone is attached and USB Debugging is selected on my phone.
Any advice or help you could provide would be greatly appreciated.
