Eos 400d ( Rebel XTI )

davo_fn

Hi!

I´m new here in this forum, first of all, sorry for my english!
I have a 400d and I´m interesting in this fix/update but this will be the first time I will make an update, so I´m afraid of damage my camera.

If I could understand correctly, when I put a compact flash without any modifications, the camera would work as usually before any mod or update, is it rigth??

Thanks.

Some success 😀 There is a "cf_extend_iso" hidden custom function. This enables ISO3200 to apear in the system menu. Some bugs with it. It doesent appear always. In a few days I will post the code and the bin file, when it's stable.

Yep. You are right. A normal card and the camera will be back to it's plain old form 😉

Well, davo, not really since the bootloader is changed.. but I tested it and you can safely go for it.
Just remember FIRST to "upgrade" to testfir.fir THEN put AUTOEXEC.BIN on the CF and make it bootable.

Great work!
ISO3200 in menu, spot-metering in menu and its mostly perfect! Thank you!

- okay, more frames per second, or an Auto-ISO-function would be great - 😉 but...

IT´S WORKS!!!!!

I followed the steps puts in this post and all it´s OK.
Sometimes my LCD turn off and I have to switch off and switch on the camara again, but this is the only failure.

Thanks guys! Waiting for the ISO3200 in the menu... 😉

Do you know if there is a way to make this work on a 350D too ?

Zibri

any news? keep us posted!

Foldesa

Congratulation!
There's many new father here. Me too 😁

Some news:
- Now I can make it show correct ISO value on screen, it change when set ISO from Cannon iso dialog and when press DP button to hack ISO also. Only when switch it back on, it show incorrect number (if switch off before with a value other than the original 100, 200, 400, 800, 1600).
- Another secret thing is I can write down Shutter Release count that Canon hide from public (to a file in CF card).

Wait for more hours, I will post my bin file and code when at home after work.

Foldesa

I don't get it !!! Damn >🙁
For some reasons I can't always turn on ISO 3200 in the menu. Sometimes it goes, sometimes not. I'm tearing my hear out 😀 My cameara is half dead anway. The dust delete hardware is broken... Anyway I will try 😀

Zibri, You mean you can display other walues not just 100, 200, 400, 800, 1600 ? Can for exampl.:320 be shown ? It would be great 😀

Foldesa

No spesific program. Just the decoded firmware and function lists, and some logs created when the camera is running and features are called and lots of try.

Hi,

Here my new files: **updated: Download newer files here: https://chdk.setepontos.com/d/3290/91
Bin: http://depositfiles.com/files/mdlitu1zy
Code: http://depositfiles.com/files/v16vcrkmg

How to use:
-Press DP button-> change iso
-Press Left arrow to display Mestering Dialog, then press DP button -> Spot meter
-Press Menu button to show camera menu then press DP to enter Factory mode (After camera beep, press Menu button twice to see Factory menu)
- Go in to "Factory Menu" dialog then press DP again to active Debug mode. After a beep, you will see CF red led blink when you press any button on your Cam. It write log to a file named 'STDOUT.txt' at the card's root directory. To know yours shutter release count, set Spot metering when in debug mode then take out and insert your CF card into cardreader, open this file in Notepad and search for string: Release.

note: the bin file have bugs. Some time it turn off display and you have to switch off then back on.

regards,

T.B.

Another great work! Nothing for real use, but it looks great.

It displays the ISO, the handling is better.

The shuttercount works!
But what is "RecentErrorX" ..... ?

Will you build an ISO-Function, that let us control the ISO-Settings in the menu?

thaibv

why not, do nothing for real use while it display real iso on screen?

"RecentError..." is some last Canon's loged error (guess: cannot focus, Error 99, Batery empty, no cf card, card full...)

Full ISO seting menu? Have no answer now but may be in future.

thanks for trying!

T.B.

Sorry, but if i'll take a picture and the camera turns off display.... No, its not for productive use. Not for ME 😉

I'm testing the aktual autoexec.bin with my 2gb CF, the older one on 4gb CF. Both are working. The older one perfectly!

If i can help you, just say a word. I would do my best.

T.B.

Oh. An ISO-problem?

If i set ISO to 100, the EXIf says ISO100
If i set ISO to 125 the Exif says ISO160
Ii i set ISO to 80 the exif says ISO100

If i set ISO to 3200 the EXIF says ISO 1600
And so on.

The problem is, if i set ISO1600 and press the "direct-print-button", dhe Camera sets ISO 2000, but displays ISO 1600. (Exif = ISO2000). If i press the "direct-print-button" twice, camera sets ISO to 2500 (EXIF) and displays 2000....
