Unable to add back storage from Linux partition after deleting ( FFFFFFFF-FFFF-FFFF-FFFF-FFFFFFFFFFFF Drive)

Question

This is embarrassing.... I want to Linux distro hop but first I need all the spaces from my partition for something before that. So, I mindlessly followed apple's guide on deleting partition, and surprise surprise: I failed.

diskutil list:

It's only after googling more about this that I found out that my hard drive have this weird FFFFFF type and that's apparently bad news.

Not sure if this is relevant at all, but in my Disk Utility, I saw something that I normally didn't see before. Normally, it would only show my hard drive (The second one in the list). But here I saw another one.... which is also coincidentally my hard drive (Normally, if I put it to show all devices, the second volume in the list would be under this volume. But now, they're completely seperate). And of course, the second volume, is still showing the same capacity with no added storage from the partition.

I'm just really damn confused on this matter altogether, the gist of what I want is that I want to fix the FFFFFF volume/drive thing and make everything back to normal. But, well I need to seek some guidance on this because I don't really know what I should do next. I'm currently just not shutting down the device at all and using it semi-normally I guess.

Post the output from diskutil info disk0s2 | grep -e Offset -e Size. And maybe sudo dd if=/dev/disk0s2 bs=512 count=1 | hexdump -Cv. — David Anderson, Dec 30 '21 at 03:30
@DavidAnderson Okay, here's the output: https://imgur.com/a/xpNnUWA — schlong, Dec 30 '21 at 03:36
@DavidAnderson It's supposed to be my SSD but I booted back on my hard drive to clean some stuff out. — schlong, Dec 30 '21 at 03:58
@DavidAnderson Yeah everything is back to normal now. Thanks! — schlong, Dec 30 '21 at 04:23

Your question is not exactly the same as this question: OS volume shows as type 'FFFFFFFF-FFFF-FFFF-FFFF-FFFFFFFFFFFF', but your question is close enough to be a duplicate. — David Anderson, Dec 30 '21 at 07:19

Boot to macOS Recovery. Enter diskutil list to verify the FFFFFFFF-FFFF-FFFF-FFFF-FFFFFFFFFFF partition is still disk0s2. Enter the following commands.

gpt -f remove -i 2 disk0
gpt -f add -i 2 -b 409640 -s 1269426984 -t apfs disk0
