Have you tried doing a Pram reset hold command -options p and r while booting or a sac reset shut off your MacBook unplug everything even the power supply remove your battery if you can press the the power buttons then put in your battery plug everything back in and power on and did you try internet recovery by trying holding command-option-r after you hear the chime
have done all the above just restarts and does the same apple loading screen or displays circle with a line crossing it
Connect HDD to the USB port and try to boot(you will need SATA to USB adapter). If it fails, you are definitely have a failing HDD, if you succeed you have a failing internal HDD SATA ribbon cable.
I put in an external usb into the port. hold down option as it powers on .
the screen comes on and the only drive that shows is EFI BOOT
This is the one you want. You are seeing EFI BOOT because your Mac does not support APFS.
okay I then click it.
the computer boots up, the patcher does its thing.. the apple logo comes on.. the loading bar comes on it takes forever..
reaches the end, reboots and then does it again
Do you have a macOS Mojave usb Patcher or do have another Mac in which you can download macOS Mojave and create a Mojave Patcher
Congrats! Your internal HDD SATA ribbon cable is fine. Your HDD/SSD is still in question, you might want to run DriveDX to check condition if you have access to another Mac.
You might also want to boot into patcher recovery and make sure that "AMFI get out of my way" is set, but I can't help you with that, look for this in this thread.
I dont have a patcher on a usb but I do have access to another mac, im reading that the latest os for my macbook was El Capitan youre saying to download mojave and do a patcher and then boot from that usb correct?
Thanks @TimothyR734 and @jackluke for your Displays prefpane fixes!

Yes I know there is supposed to be a way with the Catalina Patcher to be able to boot APFS if your HDD/SSd is formatted APFS but I haven't used that method I took a risk and use the dosdude'1 APFS boot rom patcher but is is risky as one models have more than one boot rom number and choosing the wrong one could brick you Mac I bricked my iMac 8,1 but was successful with my MacBook 5,2 and iMac 9,1 the reason I suggested Mojave it is the last macOS that still supports HFS but you can use APFS to and still supports 32 bit apps if yo still use them macOS Catalina does not If you decide to try Mojave your usb need to be 16 gb and formatted HFS-Extended-Journaled http://dosdude1.com/mojave/ here is a link and follow the instructions there

Now to figure out how to get Night Shift back in the Display settings
You might want to to do a clean install -erase your HDD/SSD and formatted it HFS-Extended-Journaled using disk utility in the patcher
im trying to atleast salvage my google chrome bookmarks and stuff all my other stuff was on an external
so a clean install will probably be my last resort
so a clean install will probably be my last resort
so update cant do thr patcher on my current Mac becuase its a 2019 and I read that dosdude1 patcher has problems with 2018 and later Macs so somehow I will have to get a hold off an old one, or just try to take a to a Mac repair store in the City and see what they say
I have never seen 2019 Mac in my life but I already know that the first thing you do is disable that horrible T2 chip and then proceed with creation of the mighty Mojave patcher.
