I've rooted my Grand 2 with "towelroot v1", and it was ok, and it gave me a root permission.
but there was no superuser app so i installed one from the market, but it needs to install some files in recovery mode, and when it goes to recovery mode it fail.
is that ok? or not?
or do i need to be worry about any thing on my device?
and i was wondering if i do a hard reset, does the factory reset remove the root. in case of any update that will come in the future?
and if not, how can i remove the root for the upcoming updated?
