Hi Masayuki,
Trouble shoot does not help. I still get the same error message after implementing the OSS messages. and all the trouble shoot steps.
I have checked the main.html on ARSRVC_UPB_ADMN, which is reading abap.js and sap-ui-core.js from resource folder; but it does not exist in UI5_UI5. 
Mime repository screen:
Any suggestions?
Best Regards,
Murali
