Software Update

Hey everyone,

Can anyone tell me why I can't install this update? I've updated it like 3 times now and it keeps popping up every time and it also showed me a message "Beta Version and there may be some errors, etc". I'm wondering why is it not installing and it keeps showing up every time my phone restarts after presumably being "installed" ? Is this some kind of glitch or something? I've attached a screenshot of the update that won't install and hope to get some support regarding this.

Thanks!
