Is my microSD really bricked?

Alright so, I have a 32gb sandisk microSD that was formatted for use with the raspberry pi.
One night I did a sudo apt update && sudo apt upgrade, let it run and left on all night by accident. The next morning, the pi wouldn't boot and my windows pc would reject the card and freeze my explorer. I read online and have concluded that it is most likely bricked.

I have tried:
  • Formatting on windows with built-in format
  • Formatting on windows with Raspberry PI recommended format tool
    You must be registered for see links
  • Formatting on windows with fat32.exe
  • Formatting on Linux (Arch) with fdisk, cfdisk, gparted, parted.

Is there anything else i could do to completely reset and clean every superblock / partition on the microsd? Or is it really bricked

I would just clear it, then reformat it :p the sd card shouldn't be bricked
Code: 
sudo dd if=/dev/urandom of=/dev/mmcblk0p1 bs=8192
then reformat it with either diskpart or fdisk

It's not bricked, you have broken superblocks. Give me output of:
Code: 
dumpe2fs /dev/mmcblk0p1 | grep -i backup

Don't cancel the dd command i should have stated if you do you can brick your sd card, it will take a few minutes as your writing 32GB of random data, this will clear the sdcard and should make it so you can reformat it

If there are bad superblocks he's still going to have the same problem. Wiping it like this can make things worse.

... why are you cancelling it. run it in screen, detach, then

Code: 
ps auwfx | grep dumpe2f | awk '{print $2}' | xargs strace -s 8192 -fvt -p
verify it's actually doing something before ctrl+c

I cancelled the dd command, wasn't doing anything.
(fdisk still the same after cancel)

back to Eckos request,

Code: 
[griimnak@revenge ~]$ sudo dumpe2fs /dev/mmcblk0p1 | grep -i backup
[sudo] password for griimnak:
dumpe2fs 1.44.1 (24-Mar-2018)


ps auwfx | grep dumpe2f | awk '{print $2}' | xargs strace -s 8192 -fvt -p
Code: 
strace: Can't stat '1495' : No such file or directory

Sorry, it's trying to strace your grep and code block messed it up:
Code: 
ps auwfx | grep dumpe2f[s] | awk '{print $2}' | xargs strace -s 8192 -fvt -p

It finally finished but it said
Code: 
unable to mount root

yeah the PI definitely cooked this card lol, it still has root boot and media volumes but everything is screwed
