Q:

How to extract data from an NAND chip with an NAND reader from iphone 6?

I am not an electrical engineer and I cannot take phones apart.
I had an iphone 6 that suffered no water damage, no smashed screens, no dust... but suddenly it got an NAND memory issue. The phone boot loops and I cannot get my data out.
I am mostly concerned with the photos. I have already sent it to 2 repair places to see if they can get the phone to turn on (this was before we found out the problem), and 2 data retrieval places, of which the last said it was an NAND memory issue. (first one just said it was a memory chip issue).
I really need the photos back. I read about NAND chip readers - my question is, are they worth it, do they work, and how do I go about getting my data back with an NAND reader when I can't do it myself? (Found readers online but I can't open the case myself, nor are my soldering skills good).
Does anyone have any tips?
(PS I live in Australia and yes I have been to Apple support. They were ironically the least helpful and least nice)

A:

You can't. The data is encrypted with a key which is unique to the individual iPhone SoC on your phone (source). Removing the flash memory from the iPhone motherboard will only guarantee that its contents are unrecoverable.
