NAND replacement is a common repair procedure in iPhone repair, whether for storage upgrade or fixing issues like not turning on caused by a damaged NAND. For NAND replacement, a NAND programmer is needed to read and write the NAND data.<\/p>\n\n\n\n

Today we will repair an iPhone with the latest NAND programmer P12<\/span><\/a>, Compared to other NAND programmers on the market, P12 supports a wide array of models, which includes NAND read & write and WiFi unbinding for iPhone 6-iPhone 11 Pro Max and some iPad models. What’s more, P12 can work without an internet connection and is free for use permanently.<\/p>\n\n\n\n

Then we use P12 to fix an iPhone XS that won’t turn on. The iPhone XS is unable to boot up.<\/p>\n\n\n\n

\"Fix<\/figure>\n\n\n\n

Then we disassemble the phone for further testing. Connect the motherboard with Power Cable<\/a><\/span>. The boot current only has 75 mA. It can be preliminarily judged that the system is faulty.<\/p>\n\n\n\n

\"Fix<\/figure>\n\n\n\n

Next, connect the phone with the computer. The phone is in DFU mode automatically. The flashing gets stuck at 19%. We can confirm now that the not turning issue is induced by faulty circuits related to the NAND.<\/p>\n\n\n\n

The next step is to replace the NAND with a new one. Remove the display and detach the motherboard. Apply high-temperature tape around the motherboard. First of all, remove black adhesive around the NAND with Hot Air Gun at 280 \u00b0C.<\/p>\n\n\n\n

\"Fix<\/figure>\n\n\n\n

Pry up the NAND with Hot Air Gun at 400 \u00b0C.<\/p>\n\n\n\n

\"Fix<\/figure>\n\n\n\n

Attach the NAND to P12. Please pay attention to aligning the NAND with the A1 pin. Click “Syscfg Backup”. Then save the data.<\/p>\n\n\n\n

\"Fix<\/figure>\n\n\n\n
\"Fix<\/figure>\n\n\n\n
\"Fix<\/figure>\n\n\n\n

Remove the NAND. Attach the new NAND to P12. Select “User Backup”. Tap “Program”.<\/p>\n\n\n\n

\"Fix<\/figure>\n\n\n\n
\"Fix<\/figure>\n\n\n\n

Next, we reball the NAND with the written data. Place the reballing stencil in position. Apply a layer of middle-temperature Solder Paste evenly. Heat with Hot Air Gun at 340 \u00b0C.<\/p>\n\n\n\n

Before NAND soldering, we need to remove tin on the bonding pads. Apply some middle-temperature Solder Paste with Soldering Iron. Clean the bonding pads with Soldering Iron and Solder Wick.<\/p>\n\n\n\n

\"Fix<\/figure>\n\n\n\n

Remove black adhesive on the bonding pads with Sculpture Knife. Then clean the bonding pads with PCB Cleaner. After cleaning, apply some Paste Flux<\/p>\n\n\n\n

Align the new NAND. Heat with Hot Air Gun at 380 \u00b0C to solder.<\/p>\n\n\n\n

\"Fix<\/figure>\n\n\n\n
\"Fix<\/figure>\n\n\n\n

Then we install the motherboard. Connect the phone with the computer to flash. The flashing has been successful.<\/p>\n\n\n\n

\"Fix<\/figure>\n\n\n\n

The phone turns on normally. After activation, the phone also functions well.<\/p>\n\n\n\n
