Recovering the data from a dead iPhone is near enough always possible depending on the situation. Of course, if the NAND is corrupt, or the CPU is cracked, then this will not be possible. In most cases though this is never the case and it can be as simple as a new chargeport, screen or battery. Some may require some board level work but that’s definitely something we’re able to do to ressurect your device.
It might even be a common problem on an iPhone called Tristar – this is where the charging IC chip dies from not using MFI certified chargers and thus will not charge your phone anymore from when it has gone flat. We can use the same techniques as we do on a Macbook logic board in-order to replace this little IC to revive your iPhone! Feel free to come to our store, or send your device into us if outside Austin. You’re also welcome to call or email us if you have any questions.
