040 firmware made to look like 78 . not hacked problem

[Stusy]

I having a spot of bother with the 040 firmware.

With the hacked firmware if i make that look like a 78 drive it works with the latest dash update, but if I take the original unhacker 040 firmware and make it look like a 78 it just gives me a E64 error.....

any ideas

You might need to also change the checksum to all zero's

ok stu, not seen u around on other forum for a bit.

anyways, i`m sort of having the same bother but in a different way.

ive made a few 47 drives, look like 078s no problem.

but come to do a 46 drive, to look like an 078 and no matter what, i cant get it to fire up.

if i do it so it is unhacked + key change + 078 version change, its fine.

but i cant do hacked + key change + 078 version ........................had a few hours out of me this yesterday so any developements on this will be inetrestiing.

If thats my drive your talking about just send it with whatever firmware works after update, i'm sure ill be able to sort the rest out myself. (p.s. please be quick it  doing me head in with no 360, been a year since i didn't have one working).
Cheers.

Nah mate I haven't been on the secure forum for a while now. Sometimes look in ever now and again. When dont you just inject the keys into a 47 image and use that instead? The hardware will supoort it.

Where is the checksome on the 040?

The checksum is located in the same place on all Hitachi drives.

At HEX address >3E7FC --- Four bytes long --- until >3E7FF

When making any changes in the firmware from >6000 until >3E7FB,
you need to set these four bytes to the right checksum, or if you set
it too all ZERO's you will disable the checksum feature.

If you wish to calc the true checksum, use a program called "firmsum".

tried that buddy (47firm) still having mixed results.

think it could be my progger.

gary, i`ll try that  cheers

Ok cheers I'll give that a go tomorrow.

1 last thing what program is used to convert the hex to assembler? What assembler language is used?

I did a hole load or assy programming at uni many many years ago, so would mind havig a butchers at it to better my understanding.

The Hitachi uses a MN103 Controller, which has it own sort-of-Risc set of common assmebler commands, much like a older 16bit computer,
but with 32bit addressing.

We use a problem called "IDA PRO" with modules written by "hitmen" to disassembly the Hitachi firmware into it's assembly form.
