Supra-
Results seem to vary from user to user: Apparently Zirowe was only able to restore the waveform with a Factory Reset of his Kindle. However the chip containing the waveform, which is an eraseable serial flash memory, a Winbond 25X20BL, if memory serves (pun intended!) is read during either a Reset or a Restart. I routinely extract the chip data using a Restart so that I will not erase the Kindle.
By the way, to do this you just need the ribbon cable from the old 3G unit containing the Spiflash chip and the plug. I routinely peel the ribbons off the broken screens and discard the glass, just saving the ribbon assembly.
Zirowe is correct about the consequences of a Reset (or a Restart). The new flash chip on the replacement screen is not flashed during either a restart or a restart. Therefore, if you perform one of these operations later on, you'll need to pop the hood and plug in that old ribbon cable again, or you'll revert back to the old washed out graphics!
