I have just tried to update my YDPG18A with the ICS update from the Yinlips website. The update (force format) said it was successful and the machine then powers on, but it seems to be stuck in some sort of boot loop. I get the full-green pic with the flying android for a few seconds, then a blank screen, then a little android man in a square on a black screen, then a blank screen, then it starts again. I've left it running in the loop for a couple of hours but it never progresses. I have rerun the update a couple of times, but always the same result. Anyone have a solution to this one? Perhaps unrelated, I did notice that the manual said don't delete the 3 main folders (.android_secure, Android, and Lost.Dir) but when I backed up the card in my PC there was no .android_secure in the root?
