You forgot a very important thing.
As you said:
second if you see my reply #1459 i try to flash my device with tl866.exe and no serial number found ...
And what i tell you what you have to do?
Please try again the flash process to change the serial number an then pay attention if device code and serial number is shown.
If NOT or you see other values than alphanumeric in this case GENERATE NEW ONE with the Random button.
You said by your self
there are no serial number.
Then you must genaerate a new one.In all the mails you dont answer my questions.
Pease read all of them not the first sentence.
Answer not with only one sentence.
We want to help you but if you dont cooperate there is no chance that we can help you.

Our mebmber ebastler have said it in in short words.
Please read the advice carefully and follow it.
I don't think that's very complicated.
