A8000 China to Hong Kong Flash OK no service

Hello,
I have a A8000 China no Playstore. I flash with Hong Kong A8000 Flash FIle: A8000ZHU2AOK1_A8000ZZH2AOK1_TGY and Used : SM-A8000 TGY pit as PIT file.

All flash done. Playstore now OK. But when insert sim write "NO SERVICE". What is the problem?

Network is 100% ok before flashing.
