1) Does the DELL recovery verify that the update.pkg is valid?
2) Does the Streak finish the copy process?
3) Does it go on to the next screen with different background, with the build number and date and a green bar at the bottom, installing the new ROM
4) After it does 1,2 and 3 it automatically does a factory reset with a DELL logo and some rainbow effects following (if you choose stock ROM 351 and up I believe this is what the boot animation does)
yes , the rainbow appeared for 2 times, then stuck at the regular dell logo...
