(For providers) In case you, the Provider, are sure that your Clients have an active service and you do no blocking, please ask your clients to generate a new Virtual MAC. Do not forget to give out the NEW Virtual MAC to your Provider. This will make your TV appear like NEW device to the Provider. Workaround: Change your Virtual MAC to NEW one. This is due to MAC CLONE PROTECTION from your Service Provider. Starting STBEMU will cause the issue to reappear. When the TV MAC is added again in the Portal, start the app ONLY ON SMART STB, NOT on STBEMU. Then, do NOT use the STBEMU as it has different SERIAL number and this causes the BLOCK (Authentication Problem) So, 00:1A:79:XX:XX:XX must be DELETED from the Portal, completely! Not disabled, but REMOVED. You need to ask Your Provider to REMOVE the Virtual MAC completely. Sometimes you may get Your STB is blocked message instead of black/grey/white screen. This problem is caused usually when you use a Portal with Smart STB and other apps like STBEMU with the same Virtual MAC.īut if you are reading this and are 100% sure your STB is NOT blocked by the Provider and activated properly please continue to read below. In case you see black screen or white screen or Authentication proboem error on a blue background, then please do this to solve the problem.
