Recently we received a case, and our engineers successfully handled it. The memory card belonged to a professional photographer. Unfortunately, data became inaccessible due to a problematic micro-controller.
If we cannot access data through the traditional interface, we use other techniques. In this case, we directly accessed its memory chips and got a physical image of data using the chip-off data recovery method.
When using this method, memory chips must be in excellent physical condition. Upon completion, a physical image needs to be converted to a logical one.
This method has been successfully applied, and we could access data and extract valuable photos.
