Thanks for everyones suggestions but I'm still getting the same message. I put off trying this for a while (months)
but after following matty's classroom thread for a while it looked pretty simple and in fact it is now that I've went through the steps 4 times, 2 from my pc download deleting that one and downloading the file from my phone directly to my internal storage then moving the file to the extenal SC Card and trying that twice.
I've never seen anyone else on matty's thread have this problem ( E:signature verification failed ) is there away to turn off signature verification and another question I have is something I've read on this and other forums about this problem, some say to make sure and download into the root of your external sd card, what the hack does that mean, how would i know if i did or not?
Hope someone can come up with a answer to this problem, would really like to have and enjoy this upgrade on my razr maxx!
Thanks Guys !
