I succeeded in flashing the sim card Japhar with OS_v5 and I replaced the old sim card by the new Japhar sim and when I still have the message BIOS NO CA FOUND! Why does not it work? I followed the instructions except that file secondstage-dm800se-84-allsim.zip does not work to flasher the old sim card always the same message INVALID IMAGE (OR OLD VERSION). I do not understand anything anymore ! In the procedure to follow ????.
The files do not work on my clone DM800HDse v2. Thank you for helping me understand.
