When existing partitions are retained, the dd call writing the uboot image in the space before the first partition was accidentally writing the whole image, making the code for individual partitions redundant. Limit the copy to 1016KiB (the first 8KiB are skipped, and the first partition starts at 1024KiB). In addition, conv=notrunc is replaced with conv=fsync. It seems this was an oversight, as notrunc doesn't make sense for block devices and all other dd commands use conv=fsync.
