Restoring old bookmarks and logins and history of operamini
If opera mini needs a reinstall or phone needs a format but you are tired of loging in again and saving bookmarks in opera mini then this method will help you a lot.
Go to c:/system/MIDlets there you will see folders of different names just open each one there
the one with a file mini.Jar is our target..
Copy the file rms.db to some other safe location and format or uninstall.
When you install it again then find the mini.jar in MIDlets folder and replace rms.db of older version with this one(older file has greater size). DONE.
