@AndroidNewbie Do you have the image of the box?

@AndroidNewbie, what kind of help do you expect to receive?

@Ducdanh Nguyen, are you sure it was my modified update.zip (hint: open it with any archiver and see for file "wipedata.flag" - is it there?)? Are old settings and apps stays in place after flashing? Are update.zip located in root of sd card? If all answers is yes, then try to update using usb flash drive instead of sd card.
