How to expand iPhone 15 Plus from 128G to 512G?
Recently, Apple released the latest iPhone 15 series, of which the iPhone 15 Plus is the flagship model, which has attracted the attention of many fruit fans. It uses the same CPU as the iPhone 14 Pro series, with strong performance, and the back cover is made with a matte feel, which is very advanced. However, for some users who like to take pictures, play games, and watch **, 128G of memory may still not be enough, and what should you do if you want to expand to a larger capacity, such as 512G, or even 1TB?
Today, I'm going to bring you good news, that is, the iPhone 15 Plus can be expanded! Although it can't be expanded to 1TB because it can't fit such a large hard drive on the motherboard, it can be expanded to 512G, which should meet the needs of most users. So, how do you scale up? What tools do you need? What are the risks? Don't worry, next, I will give you a detailed introduction to the whole process of how to expand iPhone 15 Plus from 128G to 512G, so that you can also become a master of expansion!
First of all, we need to prepare some necessary tools, such as heat guns, dismantling plates, screwdrivers, welding machines, casting and welding machines, pressure holding tools, etc. Also prepare a brand new 512G hard disk, note that this hard disk must be a new underlying hard disk that has been formatted, otherwise the flashing machine will report an error. In addition, you need to prepare a computer to flash and activate your phone. Of course, the most important thing is an iPhone 15 Plus, here I use a pink National Bank iPhone 15 Plus, the memory is 128G, which has been activated.
Once we have the tools and phone ready, we can start scaling. The first step in expansion is to remove the back cover. Since the iPhone 15 Plus and iPhone 15 as well as the iPhone 14 Plus and iPhone 14 are all removed from the back cover, we need to heat the back cover, then use the disassembly piece to pull a notch, and then slide along the perimeter of the back cover to remove the back cover. After removing the back cover, we can see the internal structure of the phone, the most conspicuous thing is the huge battery, which occupies a large part of the space, which is also one of the advantages of the iPhone 15 Plus, that is, the battery life is strong. In addition to the battery, we can also see the rear camera, motherboard, speakers, vibrator, charging port, card slot, and much more. In order to protect the screen, we first put a protective film on the screen and then proceed to disassemble the device.
The key to expansion is to replace the hard disk, and the hard disk is connected to the motherboard, so we have to remove the motherboard before we can remove the hard disk. Before disassembling the motherboard, we need to disconnect all the cables connected to the motherboard, such as the cables of the front camera and face assembly, the cable of the rear camera, the cable of the card slot, the lower antenna and the tail cable, etc. Also lay a few screws to secure the motherboard, as well as the earpiece and WiFi GPS antenna. Then, we can remove the front camera, face assembly, earpiece, etc., and set them aside to be carefully protected. Finally, we were able to take the motherboard out of the case. However, it should be noted that we can only flip the motherboard to one side, because there are also display touch cables and sensor cables on it, these two cables are connected to the screen, and we have to disconnect them before we can completely remove the motherboard.
After removing the motherboard, we can see the hard drive, which is on the side of the motherboard, and it is a small silver-white thing. Since the stickers of the iPhone 15 series are not yet in stock, we have to carefully heat them up and slowly tear them off. Then tear off the small foam on the motherboard, so that you can see the full picture of the hard drive. From here, we can see that the iPhone 15 Plus cannot be expanded to 1TB because its motherboard position cannot fit such a large hard drive. As we all know, the 1TB hard drive of the iPhone 14 15 series is larger than the 256G and 512G hard drives, while the motherboard space of the iPhone 15 Plus is limited, so it can only be expanded to 512G, which is also its maximum capacity. However, the capacity of 512G is not bad, four times more than 128G, which should be able to store a lot of things.
Since we are going to replace the hard drive, then we need to remove the original 128g hard drive first, and then install the new 512g hard drive. When disassembling the hard disk, we need to preheat the motherboard first, because the weather is cold, the glue of the hard disk will be relatively hard and not easy to pry open. After the warm-up is completed, we need to zoom around the hard disk to prevent the capacitor resistance from being removed when the hard drive is removed. Then, we can use the welding machine to remove the 128G hard disk of the original machine. After removing the hard drive, we need to drive the pads into the soldering machine, drag the tin again, and then smooth the solder joints, so that the new hard drive can be soldered later. Finally, we need to clean the pads, and we can see that the iPhone 14 15 series has very little pad glue, so it is relatively easy to clean.
After removing the old drive, we need to install the new drive. Here we are using a new 512G hard drive, which is common to the iPhone 14 series hard drive, but it must be a new underlying hard drive that has been formatted, otherwise the flashing machine will report an error. We implant a new serial number into the new hard drive, then inject flux into the pads of the motherboard, and install the new hard drive in the original corner orientation. Heat until we touch the hard drive, it has a rebound effect, indicating that the drive is installed in place. Since the solder joints of the iPhone 15 series are very dense, we need to touch them lightly so as not to damage other components. Finally, we're going to clean the motherboard, then put vinyl around the hard drive and cure it. In this way, we have completed the replacement of the hard drive.
After replacing the hard drive, it's time to put the motherboard back into the case. The first step is to install the display touch cable and the sensor cable first, these two cables are connected to the screen, we need to carefully fasten them, and then put the motherboard back in place, and buckle all the cables, and put a few screws to fix the motherboard. Then, we are going to put back the handset and the wifi GPS antennas, which all have interfaces that lead to the case, and we are going to attach them to the case with screws. Next, we're going to put back the front camera and the face component, which are responsible for taking pictures and unlocking them, and we're going to clean them up, then put them back in place and buckle the cables. Finally, we need to clean the dust inside the case, then clean the residual glue around the back cover, and then apply new waterproof glue to the back of the back cover. Then, we need to clean the back cover, install the back cover back, and fasten the only cable on the back cover. The last step is to buckle the battery cable, then clean up the dust again, remove the protective sticker of the waterproof glue, and close the back cover. In this way, we have completed the assembly of the phone.
After assembling the phone, we also have to flash and activate it, because we replaced the hard disk of the phone, and the phone cannot be turned on at this time, because there is no system inside the phone. So, we need to connect the phone to the computer and use iTunes to flash the phone, that is, install the latest system. It should be noted here that after the recent iTunes upgrade, the order of flashing has been adjusted. For example, the earliest and last brush baseband, now it has become the early brush baseband and NFC and so on. And what about writing the serial number, it is placed at the back. After the phone is successfully flashed, the reboot will bring to the activation interface. We use the one-click activation skip of AISI assistant so that the phone can successfully come to the desktop. Let's click on Settings General About This Mac, take a look, and successfully expand an iPhone 15 Plus 128G to 512G! Its maximum capacity can only be expanded to 512G, and like the iPhone 14 Plus, the motherboard cannot be placed in the position of a 1TB hard drive. Finally, we have to test all the functions, such as taking pictures, playing **, surfing the Internet, charging, etc., to ensure that there are no problems with the phone.
In this way, we have completed the expansion of the iPhone 15 Plus, from 128G to 512G, with only a few tools and a new hard drive, you can greatly increase the capacity of your phone, and no longer have to worry about running out of storage space. Of course, there is also a certain risk of expanding the phone, and if it is not done properly, it may damage other parts of the phone, or cause the phone to not turn on. Therefore, if you are not very experienced, it is recommended that you find a professional to help you expand the capacity, or buy a large-capacity mobile phone directly, which is safer.
