Spyros,
Neither do I have the capability, the desire or need to do what you are doing. However I can pose a few questions and comments that may shed some light on your issue.
1) Have you done this before with a NX8 v1??
2) If yes, were you successful??
3) If yes, what did you do this time that was different??
4) Have you tried to read the chip again with your ic programmer??
5) If yes, can you see any difference??
6) Do you have another chip that you can check that does work so that you might be able to see the differences??
7) If you have another chip that is good, then drop it on the board and move on with your day.
Hope that helps.
Les

Finally i wrote again the buffer on the eeprom and works ok.

Hi,
Am I understanding that you are unlocking Networx panels by accessing the chip directly?

There is a much easier way without having to pull out any chips on the board, and also revealing the last installer code as well as the dwld/dealer code... saves time for the next board from the same company.
