HI, I am trying to update my Galaxy S II. I go to the manual mode (by holding power, vol up and menu) and I selected the zip file for the update. It gives a "E:signature verification failed" error. I have no idea how to fix this so I can update my phone. Can anybody help me?
My Model number is : GT-9100G
Current Andriod version: 2.3.6
and I would like to install andriod 4 and up on it.
Thank you
