1) Re download the update.zip in step 2.
2) Remove all traces of update.zip off of your SD card
3) Copy/move the update.zip you downloaded in step 2 to your SD.
4) Power down phone
5) Go to post 1, and start at step 15 again.
If it still doesn't work go back to step 4. Maybe cwm_froyo didn't actually get flashed correctly. Check for errors in the left window as it goes through the process.
Nope. Tried and still not working. I:
1.) Re-downloaded update.zip, cwm_froyo, and attach.zip
2.) Loaded update and DL-30 leak to a third SD card (totally new to the process)
3.) Reflashed cwm_froyo from an entirely different computer. No errors
4.) Put battery back in, got into system recovery.
5.) Pressed apply sdcard: update.zip
6.) Got the same message as before:
Finding update package...
Opening update package...
Verifying update package...
E:signature verification failed
Installation aborted.
So, I tried flashing an older file, CWMRecovery_DJ05_DJ09_RED.tar.md5. That also flashed with no problem, but it hung from the red menu.
So, I flashed back to cwm_froyo. Still no luck.
