I had a working install of MacOS Mojave on my MacBook Pro 2010 and then upgraded to Catalina using the patcher tool (http://dosdude1.com/mojave/). It has an aftermarket SSD, and 8gb ram.
Well, I didn't pay too close attention, and updated to 10.14.4 without reading, and realized when it wouldn't boot, that i had to be careful with this update.

Oops. Well, I can easily reinstall macOS, but I cannot get the MacBook to chime now.
When open, the MacBook power LED lights, and then slowly dims until it's off.
Upon closing the MacBook, i can hear fan spin, but no sounds / image.
My first guess is that something odd was happening with the sensors for the lid, and its booting when closed. I plugged it into an external display, there is no image, so I don't think it's booting.
I have tried a handful of SMC / NVRAM resets using keyboard combinations, and even removed the battery carefully, and re-seated the hard drive and ram (carefully that is).
I have tried booting it with one ram module, no hard drive, no battery and various other situations.
No luck.
Well, what could be going on? I don't mind if I lose the data on the drive, as I have backups, I just am unsure why it won't boot / chime.
What should be done next, and what troubleshooting should I perform?
