Is your game on Internal? Try it on external with BD-Mirror enabled. (to fix sound problems)
As far as 1.06 unsupported data: I havent tried these updates yet, but you have to install ALL N0DRM updates in order, you may also not have to use the 1.00 NODRM and use the original eboot instead, if thats the case you'll have to reinstall all updates after you do this. That error is usually from not having original eboot in full game backup when an update is applied.
Also make sure you install the official sony updates 101 102 104 105 106 then patch 106 in dev_hdd0/game/(twisted metal game id)
(yet again havent updated my twisted metal yet, but this is the normal procedure i mentioned)
