iPhone X is “the future of the smartphone” according to Apple. There is no doubt that iPhone X brings many new experiences to users once again. However, users still can not avoid data loss in the process of using iPhone X. Of course, you can choose to restore from iTunes/iCloud backup to regain the lost data. Or you buy a data recovery software to regain. The premise of using these methods is your iPhone X can turn on normal. Many users usually ask that my iPhone fell in water and won’t turn on, can I get the data from a dead iPhone? So how to recover data when your iPhone won’t turn on?
As we all know, it is very difficult for repair technicians to extract data from a logic board that cannot be powered up, which requires precise operation with circumspection. And that’s what our iPhone X data recovery case is about today. The iPhone X won’t turn on after water damage. And the problem remains the same after several times of logic board repair. Well, let’s see what REWA can do…
Connect the battery connector on the upper layer with the Power Supplier and press power button to power on. Current reading on the ammeter is abnormal, so the PCB board might have been damaged.
To recover data, we need to transplant CPU, Baseband CPU, EEPROM, NAND and baseband EEPROM on the original motherboard onto a new motherboard that can turn on the phone normally. Attach the upper layer to the PCB Holder, Heat with the 858D Hot Air Gun to remove black adhesive around the NAND flash chip. Continue to heat and pry up the NAND flash chip with a specialized knife.
Next, let’s detach CPU, EEPROM, Baseband CPU and Baseband EEPROM from the board with the same steps.
Now, we need to reball these detached components
Apply tins to the tip of the Soldering Iron, then clean tins and black adhesive on the NAND flash chip and clean with PCB Cleaner afterwards. Get the BGA Reballing Stencil in position, then Smear Solder Paste evenly on the stencil with BGA Scraper and heat evenly with the 858D Hot Air Gun. So that all solder balls can solidify completely. Once completed, wait for 1 minute. Then separate the NAND flash chip from the stencil.
Continue to reball the baseband CPU, CPU, EEPROM and baseband EEPROM with the same steps. Please be noted that the WiFi module is bound up with WiFi address stored in the NAND flash chip. So our next move is to unbind WiFi. Connect the PCIE NAND Flash Chip Programmer with computer and have the WiFi unbound. We have talked about iPhone keeps searching for signal and iPhone no service with hardware fix solution.
Now, we need to solder these detached components of the original motherboard to the new motherboard
Apply some BGA Paste Flux to the bonding pad of the NAND flash chip, get the reball finished NAND flash chip in position, solder with the 858D Hot Air Gun.
Continue to solder CPU, EEPROM, baseband CPU and the baseband EEPROM with the same steps. Once done, clean with PCB Cleaner.
Next thing we do is to solder the two layers together, we need to test the two layers before soldering. Attach the upper layer and the lower layer to the Holder. Connect the upper layer and the lower layer with the display assembly. Connect the battery connector with DC Power Supply to power on. Current reading on the ammeter is normal this time, the phone can get access to the home screen normally.
Then, we need to reball the lower layer, once completed, wait for 1 minute. Then apply some BGA Paste Flux to cylinders around the edge. Attach the reball finished lower layer to the heating platform and get the upper layer in position.
Set operating temperature of the platform, with the upper layer sinking and Paste Flux flowing, continue heating for 1 minute. Then detach the motherboard from the platform after cool down.
Now we can assemble the phone and test. Get the logic board and display assembly installed, connect the battery and press power button, the phone turns on normally. iPhone X data recovery completed successfully.
Warm tips: get the phone full assembled after confirmation of fault clearance
Our REWA offers the iPhone data recovery service, but the CPU, NAND flash and Baseband CPU mustn’t be damaged. Details please check REWA iPhone Data Recovery Service. Now, let’s watch the video for more details of iPhone X data recovery from motherboard.
