EMMC Card ID Update Tool

The eMMC CID Patcher Tool is a Windows-based software developed by Knotthailand. It is used to modify the CID (Card Identification) of an eMMC chip by recalculating the CRC-7, which ensures the integrity of data.

This tool allows users to change the serial number of the chip, update the CID, and apply the changes using specialized software like Easy JTAG Plus or Medusa PRO. The process involves copying the original CID, creating a new one, and then patching it onto the chip to ensure smooth functionality.

EMMC CID Patcher Tool Process:

The eMMC CID Patcher is a Windows tool by Knotthailand. It helps calculate the CRC-7 value for an eMMC chip's JEDEC CID. Here's how to use it:

Get the Original CID: Copy the original CID from the eMMC chip using an ISP (In-System Programming) tool like ISPT001.

Enter a New Serial Number (SN): Enter a new serial number (just numbers 0-9 as suggested).

Calculate CRC-7: Use the tool to calculate the CRC-7 value for the new CID. This value is important because it ensures data integrity.

Copy the New CID: After generating the new CID, copy it to your UFI Box.

Patch the CID: Use Easy JTAG Plus software to patch the new CID to the eMMC firmware. This involves writing the new CID and making sure the firmware works with it.

Use Medusa eMMC Firmware: Similar to Easy JTAG, use Medusa software to patch the CID. First, create the new CID with another tool.

Write the CID with Medusa PRO: Finally, use the Medusa PRO tool to write the new CID to the eMMC.
