Seems like it's not clear that one SHOULD NOT touch QTweak or N9Tweak until there is a version specially for PR1.2, right now using (to apply tweaks or restore using backup made in PR1.1) on PR1.2 would just mess up your phone so I suggest to forget them until there is a new version, I think most of the backups are just original files from PR1.1 so it won't help either way. I don't think it's going to take long for a new version, so be patience. To reflash your phone using flasher, I would recommend this google translated site: tinhte.vn Remember to look for your own country code which you can find on the SIM tray. Good luck
