Tried doing this once without success, but perhaps trying to install debs in incorrect order. You obviously have your reasons for sticking with Sweden Country Variant DFL61_HARMATTAN_40.2012.21-3.299.1_PR_299, but may have to accept using different firmware to circumvent issue with N9 Repomirror. You don'y mention whether you have this 299 firmware stored locally as I doubt that will be able to source it now if "flash" is needed. No doubt you have across this thread concerning Repomirror although offering no solutions: http://talk.maemo.org/showthread.php?t=96018
