Hello there all,

I have a problem...I recently upgraded to os 4.5 but there were some errors with my telenav. To fix it I need t odowngrade back to 4.2 and then reinstall 4.5 without backing up the telenav application. When I try to downgrade there is no Prompt to do so. I think I followed the steps correctly. Can anyone post the steps to downgrading? It would be lovely to use applications that I pay for! Thanks alot guys
