Okay, let's say there were 3 versions of Thumb2 CSSU so far. when i installed 1st when i already had CSSU-T a few things got messed up (like i had only 4 desktops), but i didn't pay much attentions to that, because phone got responsiver and fast in overall. Then i updated and n900 bricked, so i did a clean install of the 2. version, without preinstalling CSSU-Testing. That went all well, and even "fixed" desktops and other little bugs. After that i updated to the last version, and phone slowed down say... 10 to 20 percent. But i will do a reflash today, and do another clean install of the last version available. Therefore i have a qusetion, do You think a eMMC reflash in this case is usefull, or shud i just reflash with a COMBINED image?

Keep in mind i didn't overclock in any of the cases...
