I did the installation of Lollipop 5.0.1 custom rom and works fine, the problem is when I was trying to install gapps file, the installation never finish and after reboot all the applications as google play services, google play store and the other ones crash, then I can't have control over my phone the only way is reflashing and have no apps, I don't know if this helps you to know what is going on with my i527m from Bell Canada.
