Can iPhone 6 upgrade its memory?

IPhone6 mobile phone memory upgrade is feasible in theory, and it is troublesome and risky to operate. Individuals are advised not to try.

Specific steps:

1, all we have to do is test the mobile phone to make sure that all the functions are normal, then brush the phone and reactivate it to see if it can succeed, which is also part of the test. Because many mobile phones will report errors when they are refreshed, and there are steps to refresh the mobile phone after replacing the chip. If the phone itself can't be refreshed, there is a great risk in modification. Fortunately, there is nothing wrong with this iPhone 6 in our hands.

This is the 128GB Sandisk memory chip that we will use to upgrade. Before replacement, there is a very important step, which is to write the serial number mentioned above, just like an identification code. Only by writing the serial number of the original 16GB mobile phone into this new "hard disk" can it be replaced, and the matching identification and activation can be guaranteed. It should be noted that the serial number mentioned here is mobile phone settings → general → about the serial number in this machine, that is, the SN code of the mobile phone is composed of a string of uppercase letters+numbers, not IMEI codes. Don't write it wrong, even if it is letters or numbers.

2. The next disassembly is different from the usual disassembly. The expansion of iPhone 6 only needs to disassemble the motherboard, without disassembling the battery or the camera, and there is no need to worry about the problem of battery deformation or camera gray. It is also the simplest step in the whole modification and upgrade. If you are skilled, it will be done in 3 minutes. Fix the motherboard, and the silver-gray chip in the picture is the "hard disk". At this time, you need to heat it with an air gun and take it out. This operation requires high technology. The PCB of iPhone 6 is relatively thin. In the process of operation, it is necessary to master the temperature of the air gun well. Judging by experience. How high the temperature is, what the distance and angle are, and when the chip can be taken down, we must accurately judge. A little carelessness may cause damage to the motherboard or related chips.

3. Before installation, solder balls should be implanted in the 128GB chip, which requires special tools and corresponding processes, and then the position of CPU on the motherboard needs to be cleaned to ensure the smooth installation of the new "hard disk". Of course, in this process, it is necessary to glue the chip to ensure that it can be more stable and avoid soldering problems as much as possible. In fact, this process is more difficult than the previous chip disassembly, and it requires higher technology and experience. To put it bluntly, good welding is a key step for successful modification, because rework after failure means starting all over again.

4. After the chip is finished, it can be installed and tested. At this time, you only need to connect the motherboard with related components and cables, so you don't need to install the screws first, because you can start the test. As mentioned earlier, due to the replacement of "hard disk", the corresponding underlying data has changed. At this time, it is necessary to refresh the machine before starting the machine, and it is also necessary to ensure that the certification can be successfully activated. This is why you should brush the machine from the beginning, so that you can have an estimate of the success rate of the last brush. To tell the truth, koalas are most nervous at this time. Although the previous operations were risky, even more risky than brushing the computer, they were often really competitive, tense and expected in the end. It was not until I saw the word Hello and finally activated it successfully that my heart was practical, followed by excitement, because for a player, this time is the coolest and happiest, just like tossing a computer and jailbreaking.

5. Finally, the mobile phone has been successfully upgraded to 128GB. Comparing the screen before modification, we can find that the serial number and IMEI part are the same, including MEID, which proves that the serial number has been successfully written into the "hard disk".

6. The success of this modification test proves that iPhone 6 and iPhone 6 Plus can indeed expand their storage space by replacing the "hard disk".
