MacBook Pro bricked after failed Big Sur update 😵 ⚰️

Hi Guys and Gals.


I saw that there was an update to Big Sur today so clicked update. It all downloaded fine and I clicked all the items to go ahead. It said it'd be a while so i stepped away from the computer. When i returned the screen was black - no status bar, no nothing, but I could tell the LED was on. Nothing would wake it up so I eventually held the power button to force a shutdown.


Now it won't boot. Tried SMC, PRAM, holding shift, option keys, recovery mode etc etc. Tried all many many times.


The only thing that happens is the LED for the screen turns on. So i can see it's slightly lit black, and the apple logo on the outside of the screen is lit up.


An automatic Catalina update destroyed my dads iMac a month or two back - resulting in a new SSD and a cracked screen from opening it up. And now my MacBook Pro (A1502) is now dead?? What's the deal?


At least it would boot into recovery mode - this one won't even get to the loading bar, or chime when i'm trying to reset the PRAM!


Any ideas? I've done everything I know to do. It was working just fine before the update, and now i'm kicking myself. Cant even do a restore from my backup!


😰

Just for info sharing, it was reported that unplugging the IO board (the one with the SD-Card, HDMI and USB port) allows Big Sur 11.0.x to further boot an "bricked" MacBook Pro Late 2013 - to finish its Big Sur 11.0.x OS install.


Once done, connecting an USB or Thunderbolt LAN adapter gets the MacBook Pro back connected to the Internet (because the unplugged IO board incl. also WiFi and BT - so not working so far anymore) and then allows Mac OSX Updater to search and update to latest Big Sur 11.1.x (Apple reported to avoid the "brick" issue with).


Once Big Sur 11.1.x update has finished, reconnecting the IO Board, the "brick" issue is solved without any hardware replacement needed.


So, wondering if it ever was/ is a bricked hardware, while this seems (at least for some) that it was/ is just Big Sur 11.0.x stuck the IO Board and therefore from booting, but Big Sur 11.1x update solve it quickly (by getting this installed with the method described above).


May this is helpful info (if not known by Apple Genius Bar Experts) and offers another way to "repair" an "bricked" MacBook Pro Late 2013 (or Mid 2014) by lower costs for the value of the users affected.
