Canon Rebel T7i/800D Error 30 After Internal Filter Removal
Camera Model: Canon EOS Rebel T7i/800D
Issue:
I recently bought a used Canon Rebel T7i/800D to use as a dedicated astrophotography camera. I attach the body directly to a telescope and control it with astro-specific software. Many people modify this camera by removing the internal filter to allow more wavelengths, beneficial for capturing nebulae.
After using the camera stock for about a year without any issues, I decided to perform the modification myself. I’m fairly technical, have plenty of tools, and felt confident following a YouTube tutorial on removing the filter. I successfully removed the internal filter and reassembled the camera.
However, when I tried to take a shot or load the live view, I got an “Error 30” code. I double-checked all wire connections and sensor alignment but had the same issue. I went further and inspected the shutter blades and springs, ensuring nothing was loose. I removed the blades, reinstalled the springs, and tested the shutter motor with a 5V test. The test worked fine; the shutter operated normally.
After reassembling and verifying all cables, the issue persists. I also tried with and without a lens attached, but the problem remains.
I’ve attached a link to pictures of the assembly and videos showing the shutter test and the camera’s behavior.

Im fully aware the warranty is no more, and I did this at my own risk, but wanted to see if anyone familiar with repair may see where my issue may be and I can adjust it. Thanks for any advice
