Eos 400d ( Rebel XTI )

mrc67

Hi Sergei,
as high iso is my preferred option I have a question to ask you:

- the camera (if enabled) has built in noise reduction for shot times over 1 second.
It would be very interesting to try performing noise reduction indipendently from exposure time.

- An addictiional very useful feature would be to fix min ISO for noise reduction application

Thanks,
bye, Marco.

Hi,

I have a Problem with the hack.

It works fine, but about 300 pics, the battery is emty. Normal are 700-800 pics possible.

Now i need help to remove the Hack.

Sorry about my bad english.

Greetings from Austria

to remove the hack, just reformat your memory card, it will be gone since it is the one you placed in the memory card which activates the hack in your camera

I know, but the bootloader is not even on the CF card, but on the camera. I want to flash the bootloader back to original state.

the change and continue running even looking for a file on the CF card.

The bootflag changing program for the 350D appears to have been written so that it simply flips the relevant bit(s) to their opposite state. So to change them back to factory default, you would just run the program again.

But I've seen nothing suggesting the 400D bootflag modifier was written that way. If someone knows for sure, maybe they will say so.

If it wasn't written that way, perhaps it could be? Surely it would be a very minor change to the source code, perhaps using the 350D source code as a guide.

Flash again with the Canon original Firmware.

Others have reported that does not restore the boot flag.

This really don't change bootflag, tryed it last night and camera stil reads fw from card when powered on.

Is the source code for the bootflag modifier available? It's testfir.fir if I remember correctly.

Paincookie

I still search for a source code or a program with which I can read the boot loader and can create a "modified testfir.fir".

that the camera always check the CF slot, I realize, but normal is not lighting up when changing lenses. And after 120 Raws is already the first graduation of the battery indicator off.

Please help me. I am in 2 weeks on vacation and can not replace the battery every 200-300 photos.

thaibv,

I just wanted to say thank you! I just installed the hook into the firmware! It works great and makes me feel like I have a whole new camera with features I believed should have always been there.

I attempted to install a link to picture of the new settings as seen in Photoshop... ISO 3200 with spot metering... awesome!

Thanks again for he wonderful work! Now we can get out the very best of 400d.

I woud like to share with you some conclusions from some test I did.
With High ISO, if shooting in JPG, Picture Style play a strong role with noise:
a Picture style too much agressive on sharpening and colors pushes high the noise.

With ISO over 2000 try Neutral Picture Style (or something very similar to it)
to keep noise under control.

Ciao, 😉
Marco.

I've done the hack and it works beautifully on the 400D! YAY! now the boo ...

After taking all the pics i tried to connect camera to computer via USB.
The camera/CF Freezes when i open the CF folder on the computer
- it displays about 16 RAW or 40 jpgs (fine) and then freezes & windows explorer ('My Computer') becomes unresponsive
- i run the original autoexec.bin (tried the 3 earliest/stablest ones)
- windows 7 64 bit
- under 16 RAW files are fine
- sandisk speed II ultra 2gb card

perculiarities:
1) CF card is fine with card reader
2) not booting with hack (ie delete autoexec.bin) - does not crash
3) uninstalling all canon programs does not solve
4) this is very perculiar

- when camera booted without hack - cr2 files appear as white icon (camera does not freeze)
- when camera booted with hack cr2 files - THUMBNAILS are shown! (i dont use any cr2 codecs)

QUESTION:
- seems like the camera can't handle displaying too many files on computer - why??? any ideas?
- why can i see thumbnails with the hack - does this have anything to do with the crash?

PS i dont think it's my OS as i installed a clean 32-bit win 7 just for the sake of testing and it's the same result
BOOHOO HELP! It seems it's only me suffering from this problem?!

roblem?!

WOW! Seems like you got a lot of things going wrong!

1. What version of the hack did you try?
2. If you don´t remember go to page 13, post 57 and start from there.

Still got problems? Please report back so others can look into it.

wtm0325

Reporting with exactly the same problem as joker97.

Using:
1) Windows 7 Ultimate 64-bit
2) 4GB Kingston CF
3) AUTOEXEC.BIN.20090913 source- http://code.google.com/p/400d/downloads/list

Got to try out Windows Vista/XP

John_Doe2

Anyone else having problems with the hack using Windows 7 ? ???

I am experiencing no problems on Vista x64 with AUTOEXEC.BIN.20090913.

wtm0325

Update.

1) Tried Windows Vista Business 32 bit
2) Disable Antivirus
3) Clear Camera setting

Same result.

mrc67

Probably if you wait for Windows 8 you will get other incompatibilities to describe...
Well why not to use another OS?
Get a linux live CD (ubuntu or similar) and try with it I promise you won't get problems......
Microsoft is unfiendly in many ways, photographic ones also!

Bye,
ìMarco.

the hack version is autoexec.bin.20090913 - i have also tried other versions with the same result.
using card reader at the moment but it is a pain in the bum

John_Doe2

joker97 and wtm0325... this is really odd. 😉

I have had no problems at all. Sorry, but I have no advice for you. Seems like you have tried everything. You could try the forum over at photography-on-the-net, they have a thread running http://photography-on-the.net/forum/forumdisplay.php?f=9

Hello fellow forum-members! Anybody want to share their experience and help out here? Anybody?
