D4 6.16.217 ICS Leak files. Download and open the zip to find the update file, boot.img (named ICSFIX) and the crc. If too many of you jump on this at once the host might go down. Be great if someone could mirror. I have a very slow dsl upload speed here and no 4g. Took about 3 hours just to get this up.
