    Data recovery with iCloud

    For phones with iCloud backup, you can recover the data from the iCloud.

    Data recovery with software

    For carelessly deleted data of phones in good conditions, you can recover the data with the help of some software.

    Data recovery with hardware

    However, if the two methods don’t work. How to recover data from a dead logic board?

    Step 1. Use screwdrivers nd straight tweezers to detach the dead logic board from the iPhone. And then attach the dead logic board to the PCB holder.

    Step 2. Detach the A8 CPU, EEPROM, and NAND Flash from the dead logic board. Please deal with these chips carefully. Because the three well-performed chips are a must of successful data recovery.

    Step 3. Use the Soldering iron and the razor blade to clean the three detached chips. Rosin, BGA paste flux and PCB cleaner are also needed during the process. Step 4. Complete BGA reballing with the help of the hot air gun rework station, BGA reballing stencil, and straight tweezers.

    Step 5. Detach the A8 CPU, NAND Flash, EEPROM from the new logic board.

    Step 6. Transplant chips detached from the dead logic board to the new logic board.

    Step 7. Get the logic board installed and test whether the data has been recovered successfully.

    Notice:

    1. There are possible risks for the logic board data recovery process.

    2. Skilled repair techs are required for the operation.

    3. The fallen pads are empty pads which do not affect the function.

    4. Apple’s official after-sales support does not accept the phone repaired by third-parties.

    5. The data can not be recovered if one of these three chips (CPU, NAND Flash, EEPROM) is broken.

    6. This cellphone is still calling failed until this step because the whole process is for data recovery only. The phone may be faced up with some other problems. Here is a video guide for your reference:
