Cerebro Premiere Back

[007.4]

All the Cerebro bios update files I've seen have been fakes.

Theoretically it should be possible to erase the cererebro OS from a card (restore to original virgin Atmel status) and then write a new Didem OS.

However, from Opos 1.04 onwards the Cerebro team made their OS non-erasable (like we did with Opos 103, Titanium 2 etc). Therefore, in practice this is not possible

If you can get the Didem OS it should be possible to write that to a virgin Atmel card. Getting the non-public OS is the problem. Once it is public, support for the card will stop instantly.

The only thing is to wait for an official update from the cerebro team, or to buy a Daytona Card.Y have twice to restore the ATR on a Cerebro Card
after loading with fake Files.For my part thats enough.Tommorow y try to buy a Daytona Card.

Files are not working in my 5400 Humax

There are three different ATRs of Cerebro card.

ATR: 3B EC 00 00 40 38 43 45 52 45 42 52 4F 20 00 0C 01 01
ATR: 3B EC 00 00 40 38 43 45 52 45 42 52 4F 20 80 0C 01 01
ATR: 3B EC 00 00 40 38 43 45 52 45 42 52 4F 20 A0 0C 01 01


They do not indicate the card BIOS, rather the card status.

If the fourth from the end byte is:-

00 = card in normal status, no application loaded
80 = card in "trapped" status, no application loaded
C0 = card in "trapped" status, with application loaded

You can demonstrate this yourself with my Erase_Opos_APP.xvb file.

Has anyone actually got a card with BIOS 1.02?

Hi,

thats interesting, where did you find the explanation for the card status/ATR?

[007.4]

Simple experimentation.

[007.4]

I forgot to add it was exactly the same with Titanium 2, Opos 1.03/1.04/1.05

der atr bleibt aber nur solange geändert (80 oder A0) solange winex. läuft.
überprüft man danach wieder den atr ist er wieder 00.

[007.4]

Yes, when the card returns to normal status (not trapped) the status byte returns to 00.

dann hätte man ja neulich als manche geschrieben haben das bei 00 die files nicht gehen einfach einen alten funktionierenden file laden sollen. hätte es dann geklappt? dann würde die karte beim beschreiben ja A0 haben.
