Card Focus defect?

Aseară am făcut upgrade la firmware pe IPBox 910HD (am pus ultimul HDMU), după ceva vreme de la upgrade (10-20 minute) oscam readerul local (internal) cu card focus a incetat să mai funcţioneze, testat inclusiv cu vechiul firmware (păstrez intotdeauna vechiul soft pe altă partiţie pe stick pentru siguranţă). Asta ar putea insemna că ori cardul Focus este dus ori cititorul din IPBox are o problemă (n-am modificat nimic in setările oscam).

Intrebarea mea este: cum aş putea să depistez problema, neavand alt receptor la dispoziţie?
Orice idee este binevenită.

Zici ca alt receptor nu ai la indemana, alt card ai ? Macar asa iti dai seama daca e de la cititor.

Nici card. In ultimă instanţă o să cumpăr un card TVR.

Eu zic mai bine sa cauti pe cineva aproape de tine sa bagi cardul sa vezi daca e bun ,,, baga si tu locatia ta poate gasim pe cineva .
Sau mai bine cumperi un receptor oficial Focus .. e plin netul . Si faci Update cu el .

Umbla la frecveta cardul pare ok da rateu la clock

Am incercat cu diverse frecvente: 1 MHz, 2 MHz, 3.57 MHz, cu acelasi rezultat. Poti explica de ce crezi ca e cardul ok? Multumesc.

Offtopic: se pierd caracterele cu diacritice, din posturile scrise in Tapatalk?

neutrin, cautama pe mess si te rezolv eu.

Update: am incercat cardul in două conserve Focus oficiale, in loc să zică "smartcard neimperecheat" zice "smartcard incorect".
E ăsta un semn că e stricat cardul? Aştept păreri.

Mulţumesc!

e f****t cardu... :)
chiar daca aparea "smartcard neimperecheat" , receptorul citea sim-ul si puteai sa vezi seria cardului, asa sim-ul este ars iar receptorul nu are ce sa "citeasca" , d'aia apare "smartcard incorect"
daca e cardul tau te duci cu buletinul si ti-l schimba gratis
ps. camd mi s-a ars cardu mie imi aparea la detali card doar siruri de zero

Pai nu ar zice ,, Card neimperecheat '' pentru ca nu se imperecheaza .. daca zice nerecunoscut e nasol ... daca nu e pe numele tau asta ..

Ba se imperechează. Cardul merge şi in alte receivere dar receiverul nu acceptă alte carduri.

Eu am Kaon 100SCO oficial de la Focus si am bagat 5 carduri Focus in el , toate merg fara probleme ... nici vorba de imperechere .

Eu am doar 2, ambele pe acelaşi abonament, dacă schimb cartelele intre ele scrie clar: Unpaired Smartcard (asta pentru că am pus eu meniul in engleză).

Daca bagi cardul in el iti arata si seria la decodor sau doar ce de la card,daca iti arata doar seria de la card inseamna ca are softul schimbat,la decodoarele care au fost resoftate pe timpul cand mergeau cu key se scrie un soft oficial focussat doar ca nu mai apare seria interna a decodorului care a fost stearsa la prima softare.

Am trimis un e-mail la FocusSat, intreband daca pot transfera contractul pe mine, nestiind cine e pe contract si ca vreau sa mi se schimbe cardul pt ca e defect. Am fost sunat de ei, mi-au cerut datele, am fost trimis la un instalator autorizat, am primit alt card, care acum isi face update :)
