SQLite Editor works
Thanks. I got 'SQLite Editor' and it worked.
After reboot, I was able to view MobileData in the toggles.
First time when you click the toggle, it brings up the setting page to enable Mobile data.
After that, it behaved as normal toggle.
I had tried below apps - But did not work.
sqlite Database Editor - This never completed loading Application database. Hence did not work
SQLite Debugger - I was able to modify settings.db. When I run the query again after reboot, I could see the modified value.
But toggle was never visible. After installing SQLite Editor, when I ran the query, MobileData was not there.
So I assume, SQLite Debugger never changed settings.db. I had system partition mounted as rw using root explorer.
