Xbox bricked after update.

It's not a power issue. I've unplugged, changed outlets, tried different houses, power bricks, tried my power supply on another console and my psu is fine.

Not under warranty. A forced update did this. Not anything else. Warranty shouldn't be the issue. The issue is breaking something of someone else's and not being held accountable.

Were you using the insider hub or preview program? There is a disclosure stating that the updates could do harm to the console, but thats the risk. Sorry that it happened to you, but there are places that it can be taken to have it reapired, the warrenty
unfourtunitly will not cove the repair

If you've not done so already. Take a look over the
Startup error code troubleshooter. It will provide you with the steps you can try to get the issue resolved.

Same thing happened to my X Box 1 S console. A mandatory update (working just fine before it) Never made it through the update. Tried offline install and every troubleshooting advise I could find, still nothing. The box is out of warranty of course too.
What crap support from Microsoft! They caused the problem, they should fix it for free.

Playstation sounds good at this point if I ever buy another console at this point...

Yep! My xbox turns on...... for 5 mins then shuts off. I've unplugged everything, made sure my external drive was not plugged in.. nothing is working. My xbox was perfectly fine till I turned it on and it ran that update. It rebooted like it was suppose
too, I went one YouTube then shut off... turned it back on.. waited a couple mins, then turned off. Waited 20 mins turned it on one last time and it turned off after 10 mins. After this point I got pissed off and said **** it. Only thing I can think of is
factory reset it if it gives me a enough time too and see if that works.. last thing I want to do. Microsoft seriously need to step up their game on updates, between console and PC. Their updates are ****.
