Any updates on the video?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.
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..
