Hacked 400D ISO 3200 and Spot Metering AND AUTOISO!

Some one release a hackable firmware for Canon EOS 400D. yes Right, i think this is the first DSLR release that release on public. the author of this release is foldase and modified by thaibv from march and now i just knew this release from my fb friend kang supri. But the full credit still goest to foldase and thaibv for this amazing mod, i just read the source file and i have no brainer to edit the file again with my needs(offcourse coz i'm not a programmer D'UH!). Ok, enought chit chat, here is the step by step how to modified your 400D with this hack version. 

if you go the forum where this hacked version released you will get tutorials "howto: like this:

HOWTO:

1. use a fully charged battery. you need CF card reader and windows. on a mac, use windows under bootcamp/vmware fusion.

2. update to latest firmware (1.1.1) by downloading the latest firmware, copying it into the root of CF, and running "update firmware" in the setup menu.

3. empty your CF, download testfir.fir from http://chdk.setepontos.com/index.php/topic,1618.0.html and copy it into the root of your CF.

4. insert CF, and then run firmware update again using testfir.fir the screen will go blank. wait 5 minutes, turn off, take battery out and back in.

5. insert CF into card reader and perform a quick format.

6. IF Card <= 4GB (fat12/fat16)

download cardtricks: http://chdk.wikia.com/wiki/Cardtricks run it, choose CF drive, tick "cf boot sector" and then click "make bootable."

ELSE IF card > 4GB (fat32)

mirror download cardtrick: rapidshare or  Mediafire

use HxD : http://mh-nexus.de/en/downloads.php?product=HxD run as administrator, goto extras -> options -> security -> uncheck "open disk as readonly by default", then open CF card using the 5th button (cd, floppy and HDD icon) in the toolbar, then carefully write "EOS_DEVELOP" at 0×47 and "BOOTDISK" at 0x5C. save and exit.

7. download autoexec.bin from here: http://depositfiles.com/files/jbygql51l copy it into CF.

8. safely remove CF, insert it into camera, if the blue print led of the camera briefly lights up when the camera is turned on, the hack is successfully loaded.

9. to use additional ISO values, choose one of the 100,200,400,800,1600, and then push the print button to access more ISOs. (80/100/125/160/200/250/320/400/500/640/800/1000/1250/ 1600/2000/2500/3200)

ISO levels 16/32/40/50 can also be enabled if you go to menu and turn "shoot without CF" ON, but not sure if they really work (i see no difference.)

10. to use spot metering, go to metering selection screen, then push the print button. to go back to "evaluative metering", you have to select other metering modes first, and then back to "evaluative metering", because the camera thinks you are at "evaluative" although you are at "spot metering".

11. to view shutter actuation count, which was only viewable by canon themselves, go to menu, push print button, push menu button again twice, ("factory menu" appears), enter factory menu, then push print button to enter "debug mode". after a beep, go back and set spot metering. and you will see the camera writing something to the CF (CF light). eject CF, insert it into card reader, you will see a file called STDOUT.txt, search the textfile for "Release". there you see a number and that is the shutter count.

thanks very much thaibv and Foldesa of CHDK for this wonderful hack.

Credit goest to raingrove for making this quick tutorial, i actually don't have any problem doing step by step, but i never tried above 4Gb Card(Don't have them)

for the sample picture taken with ISO 3200 will be updated stay tuned

Ok i'm back! here is the example pict taken with this hack: *all with ISO3200

Acceptable images, noise is plenty but for this kind of situation the important thing is not get blurred images! thx again for foldase for this hack. Full album you can see on my fb >HeRe<

try it, but don't overdo it this hack is very new about 2 month ago,.. so anything can happen…

*a little Update on October 3rd-2009

I've been playing around with this hack and has shot more that 300 images and still no error issues(i hope not). so this hack is still safe. peace out..

*Update yff

sergei made a new feature: AutoISO! yeah a new feature on todays new modern camera come to the old Canon 400D yay! explained by sergei on forum chdk:

"If anybody's interested in autoiso, here is another autoexec:  
http://www.filefactory.com/file/a19a8ah/n/autoexec_autoiso_20100112.zip
Minimum shutter speed can be set from Tv or M modes. Shutter speed in those modes will be minimum set point for Av and P (after switch from M or Tv to Av or P). And maximum speed will be minimum + 2/3 ."

a member asked: What does this actually mean?
Do you need to got to M or TV first for auto iso to work, and how do you turn auto iso off if not needed?

and sergei answered: You will need to go in M or Tv modes only if you want to change lowest shutter speed in auto iso. Software in the camera saves shutter speed value from M,Tv in memory. It will be in memory even if camera is off. Auto iso will read that value and use it as set point.
To turn off auto iso set "shoot without CF" to OFF.

i tested it and it worked on AV and P Mode, You can set the shutter speed setting in TV or M mode, and enable/disbale on menu disabla ww/o card on/off. there's a little bug though you can't set spot metering on AV mode but still can on TV mode, not a big problem
