[Question] Laude S800 telephony.db

[chiopuui]

I changed manually my telephony.db under
data\data\com.android.providers.telephony\databases .
The original one I renamed delephony.db .
After reboot the phone shows errror messages like com.android.phone etc. and
was like in loop.
With the recovery I made a backup of user data (with the defect telephony.db).
Now I tried to make an update.zip with the the original telephony.db for the recovery.
But I get only messages with invalid ota and missing scatter file etc.

How can I fix my telephony.db? I want use my backuped user data further.
