Nie reaguje na metodę tftp. W ogóle dioda power ani mrugnie ani się nie pali z i bez trzymainia przycisku factory. Wiec dla testów za jakiś czas wrzucę tam kostkę flash z innego działającego egzemplarza. Jak ruszy to wstawię nową zaprogramowaną.

Podmieniałem kości ale nic to nie daje:

Zaczekałem co będzie dalej po tych blokach i jest to:

Board HW ID mismatch,it is forbidden to be written to flash!!

Ma ktoś jeszcze jakiś pomysł...

Czy może być procesor martwy?

jak wydobyc te HW ID z obrazu?

Przy próbie ustawienia wyświetla to:

Nowa kość jest sprawna bez badów (tak twierdzi programator) w porównaniu ze starą którą wylutowałem to tam jest ich pełno jak pokazuje programator zewnetrzny

Nie ma wszystko wyczyściłem zalutowałem topnik cynel znowu czyszczenie. Możliwe że procek coś nie halo albo płyta główna? Gdzie on zapisuje ten hw_id na nandzie czy gdzie bo już nie pogubiłem co z czym on porównuje
