Lost the dictionary files through a hard reset without having a backup, don't have my CD for the 860, couldn't seem to install them from the japanese support ipks floating around (Not sure if that's what they're for), tried to do a Nand-restore from one I downloaded and found that it was post-conversion instead of a raw 1.40jp image.
Gave up on it, installed the 1.10jp Nand restore, backed up the dictionary file, Upgraded to the 1.40jp rom from Sharp's page, ran Stubear's conversion script, then dumped my own backup nand image.
Ugh.
Teaches me. Should have done a nand backup the instant I turned the bloody thing on, but Noooo.
*Sigh*
