S12_CD4 0_recovery_instructions
After installing S12 CD4.0 there has been identified some problems with the BTS parameters. The problem is caused by incorrect (old, not converted) BSD files taken into use after the CD4.0 activation.

The reason for this is either
1.Failure in file conversion (BSDCF3) or
2.Failure during the BSD file copying (converted files copied from TEMPOR to LFILES)or
3.Unexpected automatic database disk updating done by system before system restart
