To prevent damage during transportation or mishandling due to lack of experience, each purchase of the product will include 2 pcs of flexible circuit boards (FPCs). You will need to use a hot air station to remove the controller (FPGA) from the Flash Extractor Reader and then install the FPC patch. Once the FPC patch is in place, the controller should be carefully placed back on top of the FPC patch and firmly soldered. Next, a small amount of solder should be applied to connect the FPC patch to both sides of the Reader's capacitors. The patch will be powered by the Reader itself. Please note that the installation process of the FPC patch requires a certain level of soldering expertise. Before making the purchase, please evaluate whether your professional skills are adequate for this modification.

The principle behind this patch is to modify the perception capability of the Reader unit towards low voltage signals, rather than relying on an external level-shifting chip. About six months ago, I attempted to address reading VCCQ 1.8-1.2 Low VCCQ NAND Flash by creating additional adapters. However, on certain chips, this approach significantly reduced the reading quality. I cannot tolerate such results, so despite producing dozens of these adapters in small batches, they are all sitting unused in a corner now. The current solution I have developed is the best one I have tried so far. With the modified Reader, certain chips like 45 3C 98 B3 achieve a more stable dump quality compared to the original Reader.
