Users who have the most recent model of Apple smartphones, iPhone 6 Plus or iPhone 6, can have one of the two types of NAND memory. There is memory based on TLC and MLC. Why would anyone need to know what iPhone NAND flash memory he or she has? According to some users, their Apple handset gets stuck in a boot loop if they have TLC iPhone NAND memory and thus, once you know what type your gadget has, you can be sure that you can be out of trouble or look at one down the road. There is a way how to check iPhone memory type on both iPhone 6 and iPhone 6 Plus. Knowing about possible issues is always better as you can be prepaired and not waste your nerves. One little thing, only jailbroken users can currently check their NAND memory type. Users who are not jailbroken should just know that possible issues can be faced by TLC based NAN memory devices. The issue is mostly faced by 128GB and 64GB iPhone 6 / iPhone 6 Plus versions. If you have a different device, you are lucky. Step 1. This tutorial is created for Mac users.
