Adam, I must admit that I found all this files confusing just as much as you did. I guess it is because the thread is written mostly for people who have done this kind of stuff before and know what they are doing . I spend the evening trying to figure it out what goes where... repeated some of the steps again to make sure I did it all right... even tried with two different CF cards and finally it worked! I assume you already saved all this zip files, so try to go from scratch. 1. format CF card using CardTricks144 and make it bootable (you did that already)2. when you extract bootflag-20090921.zip open bootflag-20090921 folder, inside there is a bootflag folder and inside this folder there is a file scanled.fir that maiohwmai mentioned in his first post. Copy that file on the CF card3. insert card in camera, turn on, try to update firmware again (when I tried to do that the blue light was lite - usually it is orange - and yes DP is lamp button... but nothing seamed to be going on...) Luckily on this instruction http://chdk.wikia.com/wiki/350D it said to wait few minutes and than remove the battery, which I did cause it wouldn't turn off4. I inserted now my other card (this could have been done with the same card I guess but I was confused overall and wasn't even sure what am I doing LOL) and on that other card I had files from the folder cyrustam posted. I am guessing that it is all the same files as in maiohwmai zip files, just a file for spot metering is added. When you download and un-zipp 350d_iso3200_spot.zip open the folder and than select and copy all those files directly on the CF card5. insert the CF card in the camera, power on... the red light and blue light should blink, meaning that now camera is booting from CF card... and that should be it.... phew... I am so glad it worked!HUGE thanks to maiohwmai and cyrustam for those hacks!!! I know it is an old camera by my 350d still serves me very well (counter says it is over 77 000 pix now!) and since I still don't have the money to upgrade to some more expensive model this is just brilliant! Thanks again guys!
@vvumewhat you described happened to me too... camera saying that cannot update etc. I think two or three times I tried to update the firmware... I also tried to copy BOOTFLAG.BIN and BOOTFLAG.FIR like described... so I actually did this step like three times... (blue light on, taking battery out.. in...CF out.. in)... to be honest I am not even sure what exactly worked when it worked. Just don't give up. Have you checked what firmware your camera uses? How come your 350d doesn't use CF card??? Try again from the beginning following this instruction http://chdk.wikia.com/wiki/350D, try to read this as well it might help http://chdk.wikia.com/wiki/CHDK_for_Dummies but I really think that more detailed explanation is missing in this thread, and on the instruction on wikia, cause a lot of people seam to get confused over all this which is a shame cause it is a great hack and since someone took the time to make it, someone should also make for other people easier to use it.
My Rebel XT does use a CF card. I use any of these cards on my Rebel XT:1. 4GB Hitachi Microdrive2. Transcend 8GB CF3. 16GB SDHC SD Card using a CF Adapter.I have often come across requirements for a <=2GB CF with FAT16 to update firmware. I was wondering if the Rebel XT also has such a restriction.I hope one of the experts would take the further step of explaining each step in detail, particularly with regards to what response to expect from the camera after each step (how do we know firmware is updating, etc.). Here is a bunch of questions I'd like answered:
1. Do I need to remove my lens to do this (bare body only)?
2. Do I need to only use a <=2GB CF with FAT on it?
3. Are microdrives ok for this procedure?
4. Step1: Do I copy scanled.fir to a Transcend flash card as the only file and click on menu > Firmware? What should I expect the camera will do. What I get: Message "Firmware update program: CF card containing firmware is required to update." - stuck there, no response. I remove the card while the camera is on with this message after a while.
5. Step2: Make my 4GB Microdrive formatted with Windows as FAT, and made bootable by CardTricks144. Boot flags for FAT verified using HxD. Copied autoexec.bin as the only file, insert into camera that is still on with the message in Step 1, removed battery and put it back again. What I get: A very brief blip of blue LED, and then orange LED. Menus show no ISO 3200. Steps 4 & 5 should have given me ISO 3200 when I press the print button?
6. Where is the <DP> button?
7. Is this a permanent firmware change or just a technique to boot the firmware from the flash drive, i.e., the firmware is only loaded if it can find it on the flash drive being used in the camera.
