Do you know anything about the structure of the flash chip data? I see that every 0x800-byte block of data is appended with some additional 0x40-byte footer, which seems to contain some checksum. I guess you would have to fix that checksum, unless you copy them from a raw flash dump, like PouchX's one.

This is not a footer, for example. This is a part of the data.

Actually, the HWID of the x-loader and the bootloader inside PouchX's dump is 673... a new one.
