Hi there! I did what you did (use cmupdater to update and got the status 7 error). I followed verygreen's upgrade (not new install) instruction and updated to CWM 6.0.4.5, but when I flashed CM11 I still get the status 7 error. Did you install as New Install or Upgrade from CM10.x?
I then use the New Installs instruction, unzip the initial SD image, unzipped and wrote the 5 files with winimage to a SD card. But when I went to choose zip from /sdcard or /external_sd, it didn't see the files. And if I just save the initial SD img file to the SD, it will see it, but then gives me the status 7 error.
Also, there are two files there "for completeness"... what does that mean? Should I use those instead?
What did I do wrong? Many thanks to save my nook (HD+)!
