The Chip is then cleaned up by re-balling the points on the underside. As with Chip off, FMCT involves fully disassembling the device to locate the flash memory chip on the Printed Circuit Board (PCB) and using heat or more complex methods to remove the chip. We would normally secure test/donor devices and ensure the practice was viable before attempting the process with a live exhibit.įMCT pushes the boundaries of the traditional ‘Chip Off’. It’s a very delicate and labour intensive procedure but has delivered some incredible results. MD5 offer FMCT as a cutting-edge, ‘last chance saloon’ experimental repair option: FMCT involves carefully removing the flash memory chip from the exhibit, removing the flash memory chip from a donor device and transplanting the chip onto the intact, previously working handset. Therefore, any advance repairs will require specific authorisation by the customer prior to any implementation. Device repairs may involve taking the handset components apart meaning the device after may not work correctly after. If a device is not functioning correctly, repairs maybe required before it can be forensically examined. Consequently, we advise this procedure should only be considered when all other forensic extraction options have been exhausted. This is a permanent and destructive processes and consequently renders the device un-useable following the procedure.

Therefore, using specialist hardware and software enables the analyst to acquire a physical image. This procedure involves fully disassembling the device, to remove the flash memory chip on the Printed Circuit Board (PCB). Flash Memory Chip Removal (FMCR)įlash Memory Chip Removal is also known as ‘chip off’. This does not destroy the handset however, it is an extremely delicate procedure and there is a risk that the handset may not function as it originally did following the procedure. This allows the software to exploit the memory chip pins and uses the hardware to acquire a physical image by reading the chip directly. These locations exploit a direct communication with the reflected pins on the memory chip. Therefore, this procedure uses specialist software and hardware. A connection is made to specific locations on a device Printed Circuit Board (PCB) these locations are not part of the device’s PCB’s layout.

ISP is a procedure that requires a full disassembly of the device. ISP (In System Programming) also known as Direct eMMC MD5 offer the following methods which allows our analyst to extract data from handsets unsupported by forensic software, PIN/Pattern/Password protected phones and damaged or otherwise non-working handsets. We apply these procedures when a standard forensic process is ineffective, or if a device requires repair work prior to a forensic examination. MD5 offer Advanced Data Recovery (ADR) procedures.
