The storage space of a iPhone 6 or 6 iPhone Plus expandable from 16 GB to 128 GB at the moment thanks to a procedure that is not approved by the company Apple Lossless Audio CODEC (ALAC),, offers the possibility to benefit from more space for saving data.
In China, certain mobile phone services have the ability to replace the NAND flash storage medium of the iPhone 6 or iPhone 6 Plus, essentially offering the option of upgrade from 16 GB storage space to 128 GB storage space for the two terminals.
The procedure involves opening the terminals, removing the NAND flash chip from the motherboard and replacing it with a service one, the whole procedure being dangerous, with the potential to destroy that chip of the terminal, the data in it being of course lost.
How you can increase the storage space of the iPhone 6 from 16 GB to 128 GB
In the images in this article you can see the procedure that must be followed to do it upgrade the storage space in iPhone 6 or iPhone 6 Plus, but this is only half of it, because there is also the software part that must be taken into account.
The Apple company has security measures implemented in its chips, so that once you have activated an iPhone, the identification serial numbers of the NAND flash chip that does the storage are also recorded, all of which must be cloned into the replacement chip.
However, Chinese services found a way to circumvent Apple's security measures thanks to some vulnerabilities in the chip firmware and in iOS, so changing NAND flash storage media is done very quickly, even if there are dangers.
The Chinese are asking $92 for a 128GB NAND flash storage medium and $71 for a 64GB NAND flash storage medium, the price being very good for the latter type of chip, and similar to Apple's for the former.
This is the first time that the possibility of changing the NAND flash storage media of the iPhone terminals is publicly promoted, and for now everything is only possible on the iPhone 6 or iPhone 6 Plus because only these terminals have the vulnerabilities.
I could not tell you if a procedure of this kind would be possible in Romania, but I am sure that many people would be interested in it, the warranty being invalidated only if the terminal is opened after the takeover by Apple.
