If not rooted (手機沒 root)
1a) rename path /sdcard/datang_gaoyang to /sdcard/datang_gaoyang.bak

2a) rename path /sdcard/Log/app_service to /sdcard/Log/app_service.bak
2b) create an empty file /sdcard/Log//app_service
3a) rename path /sdcard/LogicDownloads to /sdcard/LogicDownloads.bak

4) reboot

(PS. the /sdcard/Log/app_service/* will keep logging, because the malwares are running, but bugged to download, and will still submitting your IMEI, etc.)

If rooted (手機已 root)
  1. remove the above 2 systems apps
  2. perform above 1a, 2a, 3a to cleanup
  3. reboot


Good luck.
