How to make a machine from a few years ago look like the latest model. This is an iPhone XR sent in by brother for repair. He asked us to change it to a 13 Pro Max look and also to replace the battery and expand the memory. You can see this is a 64 gigabytes XR. Now let’s look at the battery. The battery only has 81% efficiency left. Generally it is recommended to replace the battery if it is below 85%. This is the latest model 6.7 inch 13 Pro Max modification case. The frame is also made of stainless steel. Super new, super shiny. Enough talk, let’s get straight to it. First remove the tail plug screws. Open the screen, then protect the face ID. Then unscrew all the screws on the shield. Remove the metal plate. First expand the motherboard. Expanding is actually easy to understand. It’s like changing the memory card in the past, only now the memory card is embedded on the motherboard. You need to access the motherboard to replace it. Use a pry bar to pry off all the external cables attached to the motherboard. After removing the motherboard, put it on the operating table. First seal the gun at 280 degrees. Clean the black glue around the hard drive. Directly pry off the hard drive with a cyclone at 380 degrees. After prying off the hard drive, scrape off the remaining black glue on the motherboard. Removing glue is a real Test of a master’s craftsmanship. If you’re not careful, it’s easy to accidentally remove the nearby capacitors and resistors. That might cause the device not to turn on or to reboot. After removing the glue, take a suction strip, then wipe the hard drive again. Clean it. Put the old hard drive into AP13 and connect it to a computer. Read all the underlying data from the hard drive. Then get a new hard drive and connect it to the computer. Write the data just entered into the computer onto the new hard drive. Hard drives below iPhone 12 are encrypted. You need to write the underlying data to the new hard drive directly. Then evenly heat with a hot air gun at 380 degrees. Gently prod with tweezers. A rebound action means it has been properly installed. Okay, after completion. Now let’s replace the battery with a new cell. Changing the battery cell is easy to understand. Just move this encrypted flex cable to the new battery cell. Then use a professional machine to change its efficiency to 100. Place it on the spot welding machine. Gently press down with tweezers to prevent gaps that are too big during spot welding, which could lead to poor welding. Bring in the new battery cell. Reserve the proper position. Spot welded with a spot welding pen. We use ultra soft battery cells. Normally it’s two thousand nine hundred and forty two million amp hours, but ours is more than 3,500 milliamp Hours. It lasts several hours longer than the original. No problem at all. Cut off the excess part, then clip it around. Then bring in the Protection clip and clip it on. Stick on the beauty sticker. Moving the battery cell is now complete. While expanding and moving the battery cell, we have already modified the case. Now we just need to flash it with a new system. This flashing, isn’t it very techy? Doesn’t it feel a bit like a hacker? Ha ha ha. All steps are now complete. Install the new screen. Okay. The phone is now completely finished. The original Material Display function is also there. IPhone XR 256 gigabytes of memory. Now let’s look at the battery. Now the battery efficiency is also 100%. The phone case can also directly use the 13 Pro Max case. Do you like this modification?
