PowerMac G3 B&W 350MHz won't boot from CD

So, I bought a PowerMac G3 B&W with 10.4 on it on ebay. It worked great and I had it for less than an hour before I decided to install OS9 on it. I had a version of OS9 that installed in a DMG file for classic. I know that this version of OS9 is functioning because I have it running on my iBook G3. I assumed it would work on my PowerMac because it worked on my iBook. I transferred the file from my iBook to the PowerMac with a USB drive and once once it was on the Powermac, I began to try to install the DMG off of the USB drive. After it decompressed from its .zip format, I began the installer. It took a little while but it installed correctly. I tested out that classic mode started. It loaded and classic mode started correctly. Because it started correctly with classic mode within OSX, I Changed the startup disk to the OS9 one and then restarted the machine. When it began booting back up, it flashed the happy mac face for a half a second and then switched to a flashing floppy disk with a question mark. At this point, I realized that I could not turn off the machine with the power button so in desperation I just unplugged it. I realized later that I could hit the reset button and then immediately hit the power button and it would turn off. After a few restarts trying to get it to work, I broke out my Retail Mac OS 9.0 and Mac OS 10.3 CDs. I tried booting with the OS9 CD first but it didn't work (probably because its not a 9.2 or restore disk) so I popped in the 10.3 disc. After a few tries and restarts, I actually got it to boot from the 10.3 CD. I don't remember how I got it to boot from the CD because I was already giving up hope of it loading at that point. But it loaded and I got into the installer. (Side note, It changed resolution to a lower res at that point and its still at that res). I decided I would go and change the startup disk back to the 10.4 one but once I got to that screen, I (very stupidly, and out of pure curiosity) decided to load back into the broken OS9 system folder. I really should not have done that because I have not been able to load back into the CD since then. Since then, I have tried all of the normal tricks to get it to load from the CD like resetting the PRAM and the NVRAM and and using all the open firmware commands I could find or think of and nothing worked. Whenever I tried to boot from the CD from open firmware using the "boot cd:9,\System\Library\CoreServices\BootX" and the "boot cd:9,\\:tbxi" they would hang for about a minute or two and then read out that "Block0 Read Failed". The closest I got it to booting was when I used the Previous Open Firmware commands but instead of trying to boot from the CD, I tried them from the HDD. I typed in "boot hd:\System\Library\CoreServices\BootX" and it flashed a blue screen with some text and a finder logo for a second then it showed the 10.4 apple logo on the screen but then switched to a circle with a line through it. I don't even think the CD drive is even spinning up because the disk is in the same position as it was when I put it in after I tried loading it. Also the light will steadily flash when I put the disk in and not irregularly like its reading a disc. So thats my issue and I've been trying to fix it for a while and I would really appreciate any help I could get.
