It's alive.

I can barely believe it, but it was indeed the emmc after all.

Now to restore the backup!

I have thank all of you in a heartfelt, special way, for all the time and suggestions throughout the whole ordeal. And I will do so, by making a video explaining the case (which might be a first in the country where I live, since there are zero records everywhere) to have a register of the problem for future troubles other people may have, and naming each one of you who participated by giving me hints and insights.

I will update this topic with the video.
Any updates on the video?
I really wish to know how you did it with a different emmc module board.

My situation is since I do not have the skill to reflow and replace the nand chip, I bought the complete module (the nand + the small board)
The board have different ID from the original board, thus restoring nand backup from the original nand do not work because the encryption is different..

My steps are exactly like the video above except the nandpart, because I cannot even reach there.
I got the error below after restoring nand backup:

Yes I used that to restore, the normal hekate wont allow to restore.
I also tried balenaEtcher to write to the nand after mounted with memloader, to no avail - same error from Atmosphere.
Did you fix this? Where is the OP's video?

Hi,
This video is a concise walkthrough for replacing the eMMC. Maybe it can be of some use.

Brilliant! I never realised there was a video out there. I done this mod using a written guide. The only piece of information omitted in that written guide, was that Hekate will create a folder to store backups that has a name linked to eMMC chip. I got same error as DestinySky because I was trying to restore Boot0/1 and raw NAND from incorrect location on SD. I got around this by creating a random dump through Hekate with new blank 256gb eMMC fitted, (I think a fuse dump.), this created a brand new folder of which contained the correct Recovery folder that I should place NAND backups.
