sch-i435 upgrade from 4.4.2 to 5.0
I have a SCH-I435 I am no longer with Verizon and have not received any updates since Nov. 2014 . I have heard there is a upgrade from 4.4.2 into a 5.0 . I'm not very up to date on all the different terms. Can someone please give me step by step instructions . Also my phone has been rooted.
