Problems with Skydragon on M7 after release keys update.

Hi. I got Skydragon GPE-LRX22C.H3 release keys installed on HTC M7. Automatically, it downloads the "release keys LMY470.H9" update. Every time it powers off, on reboot, it installs it. After rebooting, it keeps optimizing apps, finishes, reboots again, and again the same loop. It never ends. I have to reboot it with the TWERP and do a restore, as the only way to get mu phone back. How do I do to stop it from downloading the update, or how to do to get it installed right? Thanks in advance.
Marcos.
