Unmount and insert sd card again if opera mini was installed there. Pull the battery and SIM for 5 min and reboot in offline mode, after a while reboot with SIM on-board, Opera Mini is alive? If not download again the latest v from m.opera.com, saved pages can be found in the same place (folder). 1. Better access mini app via app/games folder rather than fast access with one click. 2. Avoid heavy usage of default storage space, all media content should be on sd card and all important apps on phone memory if I got that right for Nokia devices.
since it will be useful only for old phones then most likely light dimming feature is doomed. #3 from mini4 it's a miss and reloaded forms another glitch for java version. Easy and without fuss Opera Mini 5 for j2me tend to serve a more deprecated user experience since all new features are developed for Android and implemented on other platforms for compatibility reasons. In fact Google which is Opera's default search partner for Opera Mini and Opera Mobile has to be the monicker in this affair just dusting and of course Opera sweep.
Maybe here is the reason: I have only 1.xx jre version. But I have seen that in workable Chrome on another PC, there is also another 6.0 version or update. So maybe I need move such folder from another computer or install this update. Maybe operamini simulator needs some higher version of java environment?
