I have done that too. But the question of what causes the rebootloop still remains..
I noticed the following wierd phenomena:
In the transitions.ini file there are no spaces in the blurrless and blurless_saturation lines, but there are spaces in the other lines in the thp_tweaks section... (after using CSSUfeatures config)
After manually adding spaces in the blurless and blurless_saturation lines my hildon strated crashing. The obvious solution is not add the spaces. But without these spaces, the CSSU feat. configuration cant seem to change the values of blurless and blurless_saturation. It says it saved the new config sucessfully, but after checking them manually, there haven't been made any changes... Has anyone else noticed this too, or can anyone confirm this?
