I have the same problem. I updated SFOS to 3.1 and after it I activated all patches. Then I updated all in Respo and now I have PM3 and can't deactivate all patches in real, because the new PM3 don't work with the original files. If I install PM2 all patches are deactivated but I can't activate this, because I get a message that the patches are not compatible with my SFOS because the PM2 don't have a developer mode. All patches works perfekt but I cant deactivate the patches real. Could you upload the last Version of the PM2 before the Update to 3 with a developer mode. Maybe this will help us. After this we will use PM3.

Thanks in advance and sorry
