  8. Can I use that CNC machine to remove NAND with earlier version of Iphones e.g. Iphone 5S too?
    Or must I have the NAND not damaged because I need to read it first and then to upload some data to the new NAND first?

  9. I am a simple man. I see REWA uploaded a new video, I stop what I am doing and watch.

  10. Not an easy repair, you can do it without the cnc machine but you need skills to break the sdram without bothering the cpu, to bad you didn't show that the phone gets to dfu before you put the new sdram. This is a common fault on the 7 series after a drop the sdram gets shorted. Nice video btw.

  19. We will arrive to the point in the future when repairs cannot be don like this becase the whole motherboard will be a big black square and it will only have a few connectors on it.
    Apple is really going that way cramming the cpu and ram together.
