Does anyone know what to do when you get "unable to connect to target" no matter how many times I've checked my solders and even tried on two different controllers? I'm at a loss as to what to do here

Flash ESC with fulldump using an ST Link. Do some research, and you'll find the method :)
Would you be able to elaborate on where to find this info? I've been searching but haven't found anything of use other than this wiring diagram:

showing where to solder each pin.

Is there anything else you need to do (like remove any capacitors)? Also would it be possible to use OpenOCD as opposed to fulldump? I'm assuming TVCC is 3.3v, but I'm not totally sure, so let me know if you have any info (I have the knockoff ST-LINK V2 suggested in the dashboard flashing guide, which doesn't include a TVCC pin). Thanks for the help by the way.
The schematic you found is indeed correct and it's the same one I use ;)
There's nothing special to know, just solder and flash. TVCC is indeed 3.3V.
As for the flashing part, fulldump refers to a fulldump file of the DRV (bootloader + firmware + user settings), and you can flash it with OpenOCD or STM32 utility.

Good afternoon I would like to know what is the correct scheme for welding because I see in the photo that indicate some red circles but it does not indicate which capacitors have to be removed and on pages later I have seen another user who has the same doubt. There is also another image with different indications. So my question is, where do I have to drop exactly, and if there is a capacitor to be removed, which of all is it? I would appreciate it very much please. especially if I could upload a photo with more precise indications. Not just a few circles. Thank you

I would be very grateful if you can help bring these drivers to life. For my part I have one totally dead because of bad flashing. greetings and thank you very much

All info is in the second post of this thread.
Why make it more complicated than it is?

Nowhere does it tell you to remove a capacitor, so why do you want to do that?
Also, why care about the red circles? The needed information about the solder points is in the picture too.

moiskey, blackass I can help you with chip programming. I found a way to connect to STM32 if flashing was wrong for some reason. You can find me on discord mircamen#3886
