Fase 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.
Passo 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.
Fase 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. Passo 4. Complete BGA reballing with the help of the hot air gun rework station, BGA reballing stencil, and straight tweezers.
Passo 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.
Passo 7. Get the logic board installed and test whether the data has been recovered successfully.
Avviso:
1. There are possible risks for the logic board data recovery process.
