There are videos on Internet about changing NANDs.

You will need to pick the chip from donor board, same position.
We don't have yet positive feedback left on the forum about this.

So it not possible to replace it? Since there is no positive feedback. Just wanted to know possible or not.

After dfu. I got the operation….(Amrestore….error 6- failed to …. And it’s same board same side but not precise about the position. Should I give it another try or it’s not possible

People claimed on Internet that only worked with chip from same position.
