Xbox one update loop...

Okay so, this is gonna get pretty lengthy. I have an Xbox one OG console. I'VE NEVER ONCE HAD AN ISSUE WITH THE CONSOLE JUST SO EVERYONE IS AWARE...

So on December 10th of 2020, (the day the series x came out) my console had an update. Within that update that was going ever so smoothly, it got to step 3 of 3 (31% of step 3, and 71% of the entire update) which is applying the update to the console,
my Xbox screen went black and pulled up the troubleshooting page. It had an error code saying System Error and E100...... you know how it goes. So, I jumped on google and typed the code in. Brought me to the Xbox error code troubleshooting menu. Did all the
steps it told me and my console is still NOT WORKING. Did the reset, then the factory reset and keep games, then the factory reset and remove everything, then the Offline update, then tried to make a repair claim (apparently, my console is too old. Literally
bought it a year ago from Walmart brand new off the shelf but okay...). So now I'm stuck with a completelyyyyyy dead console so I took that bih apart. Like Wt f else was I supposed to do at this point? Watched some youtube videos, safely removed the HDD, bought
a SATA to USB cable, and repartitioned that whole damn thing. Plugged it back in and put the entire console back together, just to get back to the same damn place I started... I was triggered as I'm sure y'all can understand. Now I am f'ing clueless as to
what to do next. I don't have any more money. I bought another HDD same exact one from the console, repartitioned that, same problem. Tested the resistance of every electrical component on the motherboard. Everything is within spec, so I'm literally just stuck.
I DONT KNOW WHAT TO DO. Can somebody pleaseeeeeee give me pointers? I've been workin at this since the day it gained a chromosome.
