Thank you! I did tweet with Mike1986 when I first had trouble, I did say I was trying on Sprint since it said '" All M8 Models in his post and he did not say it was not Sprint Compatible so I assumed it was. All he asked was if I had Sprint boot.img on my phone. I am not sure what that meant and after searching the net and XDA, still don't know and said I would try other sources for help.
It does seem not seem to work on Sprint, I am almost positive I followed all of the steps, unless there is something completely different from M7 Flashing that I am not aware of. Rooting worked like a charm but as I said before, and thank fully so, after flashing, the phone reboots right back to the fastboot.
It does give you a scare at first as it goes completely dead for a few minutes but then finally shows up in Fastboot and can be wiped and the backup can be applied.
I'll keep looking around for info!
Well, enough said for sure.
Thanks all for your input!
