There'll be a way to extract the data from the flash backups you have, which you can then write to the device in a way that knows about the bad blocks. The ams_delta installer script will be doing exactly this. I can't remember what any of the E3 partitions do any more but the big one will most likely be a JFFS2 filesystem. Loopback mounting those JFFS2 images is a pain because you need to use mtdram to fake a flash device.
If all else fails, you can always run ams_delta on it.
