Thanks a lot Smatt23.I will try this and post my update here.
By the way, should I check the "Re-partition" box or leave it unchecked?
So, even if someone roots the phone, reinstalling the original firmware upholds the warranty? I mean can't they find out the phone has been rooted?
Sorry for asking too many questions, I am very new to all of this.![]()
attahas: From the guides I have read, better not repartition.
I believe that reinstalling the original firmware will unroot it, and thus uphold the warranty. However, this is just my belief, I could be wrong.

Is your VPN working? Mine works on wifi, but now it doesn't work with china mobile data connection, but it did with stock firmware.

I will try this and post my update here.
