Thanks!

Very helpful tool. I used it with our LG Leon phones AFTER rooting since I couldn't get the OTA updates to install. This tool gave me stock which included the latest update, and then I re-rooted the phones (using the guide for the LG Stylo) and was back in business. I've got another OTA update, so have grabbed the latest KDZ file to repeat the routine. I HOPE the latest update will still be rootable. If NOT, then I can easily revert to the prior KDZ file and be no worse off but for the time spent. Good to have this utility.

According to T-Mobile US rom update H345K was released for the Leon H345KT on December 5, 2016 it is supposedly Android 6.0.1 has anyone been able to find it on the LG servers? Oh T-Mobile support is saying this update will only be released via OTA push in other words you won't be able to use LG software on your computer to do the update which sounds strange to me
