Hi Youwang,
Can you suggest the import phase you are stuck in. Refer to SAP Note 1597765 Known problems with Support Packages in SAP NW 7.31 AS ABAP..
If there are lot of dumps and stuck in IMPORT_PROPER phase, Raise a OSS message to SAP they look into the system and suggest few checks and would provide a tp in order to progress further.
Regards,
Sandeep Singh
