[Q] What's the next step? topic

Hi,

This is my first time doing this and I've been doing pretty good until I get to this stage where I got the status 7 error while installing zip file cm-11-20140217-NIGHTLY-d2spr.zip. I want to transfer other files (cm-11-20140203-NIGHTLY-d2spr.zip) to my phone but when I reboot, the logo still stuck on "Samsung Galaxy S III"...

I am still able to go into PhilZ Touch 6 CWM Base version 6.0.4.5 but I don't really know what to do from there. The files I have currently in my phone are:
DE-SAMSUNGNIZER_KNOX_REMOVAL_SCRIPT_V1.0.zip
UPDATE-SuperSU-V1.93.zip
cm-11-2014-0217-NIGHTLY-d2spr.zip
pa_gapps-stock-4.4.2-20131230-signed.zip

What I did was:
1. Rooted my phone using Odin and verified that my phone was root via RootChecker app.
2. I went to "Wipe Data/Factory Reset" and chose the option to "Clean to Install a New ROM".
3. Then I received the error Status 7 message
4. Reboot and it also said "Root access is missing. Root device?" then either option (yes or no), still stuck on the Samsung Galaxy S III.

My phone is Sprint Samsung Galaxy S III 4.4.2, SPH-L710 and I followed the instruction from this website: http://forum.xda-developers.com/show....php?t=2596697

Your assistance is greatly appreciated! Thank you.
