Restore your TA backup.
That will relock your bootloader, of course.
Then just flash official ftf (you have almost all region here on XDA to download).
Flash 136, don't go to 534.
But remember : flashing ftf through flashtool will wipe everything.(and it should)
So backup all your files.
If you want this only for updating to 136, as I can see, many guys just flashed NUT stock deodexed 136 without wiping anything and it's working.
