I did not get an Error 7 as far as I can remember. I was just a message saying the attempt failed. I can try again this evening, and get the exact message.
As far as I can determine, I have the latest 4ext:
4EXT Recovery
v1.0.0.5 RC9 Testing build:70
I think my firmware is version 3.33, but I can't remember and find how to determine that.
HBoot 1.29.0000
RADIO-11.24A.3504.31_M
Was wondering about my radio, and found a thread, but the number they list are version different and for ICS or Gingerbread. I'll have to read more on that.
