Eos 400d ( Rebel XTI )

hi guys, hi thaibv

thank you for your help and your efforts,

i'm also have the problem with a bootable card.
my camera starts everytime (with/without card)
My cards a Sandisk Ultra II GB and TRANSCEND 133 2GB and my camera are a eos 400D (bought in germany) with 1.1.1 FW

thaibv

Hi all,

Reflashed my 400d firmware, format and prepare my card again and it work like a charm.
I use Transcend 2gb 133x. My firmware 1.1.1 downloaded from Canon USA site here: http://www.usa.canon.com/consumer/controller?act=ModelInfoAct&fcategoryid=139&modelid=14257#DownloadDetailAct

Very sorry!
Now my local time is 2 am, will borrow another card tomorrow and find out why.

You wrote if my card is bootable there will be a failure or something like this, you wrote it will hang and I can´t turn on.
But even without a card I can turn my camera on, but with an error message...
Did you meant this with "will hang" - that there will be an error message (if my card is bootable but I have no autoexec.bin on it)?

When power on, your cam behave as follow:
- Without a card in: In turn on with warning message "No CF card"
- With not bootable card: It turn on with no message
- With a bootable card in and a correct autoexec.bin file at the root directory of this card, it run the autoexec.bin file.
- With a bootable card in and this card have no autoexec.bin file or bad autoexec.bin file, your Cam power led will turn on (green) but the lcd screen will not.

if it doesnt boot the hack you cant set the iso...

lykantroph

IT WORKS 😀

i do the posted steps by thaibv and load the testfir.fir on the cf card (https://chdk.setepontos.com/d/1618). After i go to fw-updade at the camera menu, the cam loads and "hang off".

i removed the akku and started the camere seconde time, and i see a blue led blinking.
If i put a "normal" CF Card, it work normaly...

THANKS GUYS FOR YOU HELP!!!

T.B.

bingo!

Thank you guy! And tahibv!

But it doesn't show the ISO on the display? Is it right?....
Another question: What is "Factory Mode"?....

Great work! testfir.fir is the trick

lykantroph

this is right, you have to remember your iso settings, or looking to the information of the last picture.

thaibv said something about reset the metring-mode from spot to default, with the factory mode

lykantroph

ah factory-mode

if you press it, you have at the cam-menu a new point "factory" and you can do some camera test/checks 😉

Oh my God!
Thank you Lykantroph! you have a big finding.

Sorry guys! That's all my mistakes. I don't remember exactly when, but i am sure that i tried the file testfir.fir before as Lykantroph did above.

I really confused about the name of that topic is 'Rescue' and what Owerlord said:

owerlord

Why I'm writing it? Two reasons:

1. So if you'll break the camera like that, mayby it will help you (attached .fir and AUTOEXEC.BIN)
2. As I said in a other thread: I'm not rich man - I was terrified when It happened (guarantee expired, so much money!), and I had to write somewhere 😀

So I think the testfir.fir file is for rescue only (if I brick my cam) and did not recognize that it is the key step. 😖

But now everything are OK, please enjoy the hack.

lykantroph

doesn't matter thaibv. 😁

Now it works 😀 Thanks a lot for the autoexec.bin
Can you maybe tell us what other features are still available?

Foldesa

I don't know about many features more, but I'm working on some auto iso functions. It's not fully ready, but it will be 😀 After this i want to integrate functions in the system menu, so we don't have to press keys, to enable them. Simpli select it from menu. Untill then enjoy these bin's.

Sooo happy, you made my week 😉

Big thanks to the developer and helper of the hack!!!

PhyrePhoX

i guess this is the first DSLR modification that really is released to the public. congratz. this will be big news for the dslr sites - i guess. hopefully this will be explored more, and more devs come join in on the fun (without financial interests of course 😁).
btw welcome to the elite circle of devs on this board, Foldesa. Time to introduce yourself, i mean, you havent really been active before the 400d hack on this board here, have you 😉

lykantroph

yes, really great work guys!!!

thaibv and foldesa you spoke something about shutter speed? what you mean?
Is it maybe possible to raise the picturefrequenzy?

thaibv

[unknown]
am i allowed to write a full howto, for sure with thanks to thaibv and lykantroph, with the links to the files
and upload it on another german board?

Bugmenot, may be you can. Becoz the moderartor PhyrePhoX wrote:

But you should ask The Moderator for allowance, I think.

PhyrePhoX

lol. go ahead 😁

Foldesa

Wow, hold your horses 😀
So many requests ( witch I also want 😉 ) and so little time. I only have a few hours a week for this. My family and work takes most of my time.
Anyway, I think enableing ISO 3200 in menu should not be hard. There is a string for this in the firmware. Maybe it's a hidden function. I will try to find it after my wisit to Prague 😀 Then I will finish auto iso. After this I will try integration to system menu. This is the order for me. Maby someone else is tring such things, and share our expiriances.

Go slow foldesa, doesn't matter. Your work until is great.

I wish i can help you but my asm knowledge is realy smalllll.... :😀

Zibri

Very nice !
I also got crazy not booting anything before I understood testfir.fir was a necessary step.

Now I have a few questions:

1) What does testfir.fir ??
2) Where does it come from ?

I don't just wish to use this hack but to contribute as much as I can.

About AUTOEXEC.BIN, which is the best at the moment?

I noticed people is using cygwin and an arm toolchain to build it.
Where can I find more infos?
