I don't know whether to be impressed that Metazoa cracked it so quickly, or not surprised at all, as XOR is a notoriously poor choice for obfuscation/encryption. Anyway I did not think of XOR, so hats off to Metazoa.
If Kobo really want to stop this hacking, then perhaps they should make the firmware more configurable, and thus remove the need for the patcher. If they don't want to do that, then for heaven's sake leave the door open for us to patch it.
