If you have root, copy the old Sense apk's with right permissions to system|priv-app and reboot. It must be a version of Sense where you still can log in.
If you are logged in, go to the priv-app folder and replace the old apk's with newer version of Sense. Don't log out, don't uninstall, don't delete data.
Reboot. Now, the already logged in data from the previous version should still work with the newer Sense.
At least that always worked for me.
Yes but there is no version where u can login anymore..
"SGNGX : file not found 404" in any version of sense
