Starting problems on BMW 3 after replacing spark plugs and coils

Hi all, I have a 2009 BMW 3 with 100507 km and I am facing a serious problem. The car does not start. Initially, I changed the spark plugs and the car started but misfired. Then, I decided to change the coils, but now the car won't start at all. Has anyone had a similar experience or know what could be causing this problem? I would appreciate any advice or suggestions. thanks!

Check the battery voltage first to ensure it's fully charged, as a weak battery can prevent the car from starting. If the battery is fine, inspect the connections to the coils to ensure they are properly seated and connected. Let me know how it goes or if you have further questions!

I put a new battery but it still does not start, there is no warning light and no code, the only one that appears after scanning is 00A10A.
