I decided to share my 5600 NAND backup file with the community. It is 250 CPU, basic the Kompany ROM with no additional software. The size of the file is 67Mb. I have just made it and have not tried restoring from it. I could not upload it to the Download section here (maybe there is size limitation). Please post here if you have web space on http or ftp server to post this file. I do not want to disclose my email to everybody in the world.
