I bought a s4 yesterday that was rooted with hyperdrive. I was originally just going to put the phone back to factory but after I got to playing around with it I decided I liked it the way it was. I'm new to all this rooting stuff so not 100% on this. Im trying to install the new updated hyperdrive software and am having trouble. I rebooted into recovery, did factory reset, wiped cache and dalvik then went to install and found the file I downloaded. When I tried to install it it said failed. What am I doing wrong.? I'm afraid I'm going to fry my phone. Please help!
