Nevertheless, problems/bugs are as follows:
1. Bluetooth detectable but no working scan nor successful pairing.
2. Camcorder crashes upon mode changing/simply doesn't work.
3. Long pressing hardware home button doesn't give background management
Back to the title. Please check your update_script and look for the 49* lines with a text editor (I suggest Jota+), delete the doubled parentheses, repack, flash and enjoy!
Sorry for posting it here for the simple reason that I'm new here and hence not able to post anything in the development section. Nice work here! Tested on a TW T8585 LEO512 with DataOnExt and almost everything is working here: smooth transitions, working sound and HDA (not perfect, i.e. defective 720p decoding but useable with lower definition), seemingly working SD mounting (test not done yet), smooth Rosie and fast WiFi/3G (if only the latter didn't crash that often).
