An update- it actually cleared itself up, I had it plugged into the usb port and left it on for a while, and when I unplugged it, it was working again. Go figure. I still want to install the hack, but if I could, I'd like to ask for a little clarification on a few of the steps:
3. empty your CF, download testfir.fir from https://chdk.setepontos.com/d/1618 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. download cardtricks 1.45 : https://chdk.setepontos.com/d/4214 (first download link). Run it to self extract the archive. Run the binary extracted, choose CF drive, tick "cf boot sector" and then click "make bootable."
7. download latest autoexec.bin from the list below and copy the ONLY AUTOEXEC.BIN to CF card.
8. safely remove CF, insert it into camera.
step 3 says, "empty your CF". Does that mean format it, or delete the other files on it, or just take it out of the camera?
After step 5 you have an empty cf card, is there no need to reinstall any of the .fir files? Just the autoexec.bin file after it's been made bootable?
