Launch the latest version of TB and go to menu, more, create update.zip. Choose Amend as scripting type, choose TB will be installed as system application, and you can choose either options as the name of the output file.
Now your ready to flash it. Reboot into recovery, choose install zip from sd card and toggle signature vitrification off then choose the file you just made. Reboot and TB should be working fine.
This will be added to one of the OPs now.
