I'm sorry to make my first post so noobish, but I've been trying for a day now to get CM 11 onto my phone, and the installation keeps failing, something about the signature failing. I tried miui just to see if the rom iteself was the issue, and i had the same result. I have the phone rooted via odin(CF-Auto-Root-d2can-d2vl-sghi747m). I found a rom (cm-11-20140217-NIGHTLY-d2att) and dropped the zip on my sd, popped that in, put the phone in recovery. I formatted and cleared cache. Then tried to install the rom from external. I see it there but the installation fails every time.
Where am I going wrong? do i need something else on the phone?
thanks for any help.
