On CyanogenMod 11 snapshot M8 I have the notification LED setting in
This is the main settings database and contains most (if not all) of them. You probably don't want to transfer the whole bunch, so you have to extract it.
At first, there were 2 files in my backup:
settings.db (the interesting database) and
settings.db-journal (its "rollback journal"). The journal contains data that were yet not transferred to the database due to unfinished transactions or maybe for some other reason. Still, before dealing with the database itself, it's better to process the journal. This little (Linux) command did the trick for me:
$ sqlite3 settings.db VACUUM
After this, the journal should be merged into the database and removed. I've found that the LED settings we are interested in are in the system table. This will get them for you:
$ sqlite3 settings.db "SELECT name,value FROM system WHERE name LIKE 'notification_light_pulse%';"
I suppose the most interesting ones are:
I'm afraid I don't know a good way how to transfer those values to your current settings database, though. You should definitely be able to stay with the
sqlite3 tool, maybe use its
.dump meta-command and then filter it and insert the selected values into your database. This might get messy, though, as the indexes might differ. I'm really no database guy, sorry. Maybe some GUI tool like SQLite Browser might be easier for the job.
Should someone know a good and easy way I'll be glad to update this response.
