  1. Apply appropriate heat to remove the shield and the chip underneath. There will be epoxy on the chip so take your time, use adequate heat and gently remove the chip from the board. From personal experience, the 9900 has the highest failure rate for chip-off due to this epoxy ruining traces at the edges/corners of the chip when removing from the board, or during clean up.

  1. The chip is now ready to be read. The chip in our test phone is a SanDisk SDIN5C2-8G. It was read using a Sireda 12x16_0.5 adapter. The resulting .dd was parsed in UFED Physical Analyzer.
