I have it unlocked, rooted with Super SU (verified root access) and CWM for Spr.
I downloaded 4.4 OTA and when I try to install, it loads into CMW, and imeddiately aborts. I try to load rom from Sdcard/download and select the the zip.
It verifies the file, then checks for signature. I toggled OFF signature verification, and it still continues to Abort. Here is the abort message.
The only thing I dont' have is S-OFF. Not sure if that is what is causing the issues, but I haven't found an easy way to S-OFF with a mac
I am also on Hboot 1.55
