EMMC CID Patcher Tool 2024 || Latest Update
Hey friends welcome to Tech GSM Software. The EMMC CID Patcher Tool is a Windows-based software tool developed by Knotthailand. Its primary purpose is to calculate the CRC-7 value for eMMC JEDEC CID. This process is essential for making changes to the eMMC chip's CID (Card Identification), which includes modifying the serial number. In this guide, we will discuss the steps involved in the EMMC CID patching process using this tool, covering topics such as copying the original CID, calculating the CRC-7, patching the CID, and using software like Easy JTAG and Medusa PRO.
Understanding EMMC CID:
Before diving into the patching process, it's important to understand what EMMC CID is. CID stands for Card Identification and is a unique code stored on the eMMC (Embedded MultiMediaCard) chip inside devices such as smartphones, tablets, and other electronics. This code contains important information about the card, such as the manufacturer ID, product name, and serial number.
Copy the Original CID from the EMMC Chip:
The first step in the EMMC CID patching process is to extract the original CID from the eMMC chip. This is typically done using an ISP (In-System Programming) tool. The ISP tool is connected to the eMMC chip, allowing direct communication with the chip’s firmware. A popular tool used for this purpose is the ISPT001.
Steps to copy the original CID:
- Connect the ISP tool (such as ISPT001) to the device’s eMMC chip.
- Use the ISP tool’s software to read the CID from the eMMC chip.
- Save or copy the original CID code for future reference.
This step is crucial as the original CID will be used to create a new CID, and any mistake in this process could lead to problems during the patching phase.
Enter a New Serial Number (SN):
Once you have the original CID, the next step is to modify the Serial Number (SN) within the CID. The Serial Number is a numeric value that is part of the CID code. When changing the SN, it is recommended to use only numeric values ranging from 0 to 9.
Steps to change the SN:
- Open the EMMC CID Patcher Tool.
- Enter the new SN value in the designated field.
- Make sure the SN is numeric and within the recommended range (0-9).
Changing the SN is usually done to resolve issues related to faulty or corrupt serial numbers in the device. The new SN will be used in the next step to create a new CID code.
Calculate CRC-7 with the Change SN CID - CRC7 Calculator:
After entering the new SN, the next step is to calculate the CRC-7 value for the new CID. CRC-7 (Cyclic Redundancy Check) is a form of error-checking used to ensure data integrity. It helps to verify that the changes made to the CID are valid and won't cause data corruption or hardware malfunctions.
Steps to calculate the CRC-7:
- In the EMMC CID Patcher Tool, navigate to the CRC-7 calculator section.
- Enter the original CID, the new SN, and other necessary information.
- The tool will generate the CRC-7 value based on the new CID.
This step is important because the CRC-7 value guarantees that the new CID will work properly with the eMMC firmware, preventing any issues related to incorrect data.
Copy the New CID:
Once the CRC-7 calculation is complete, the EMMC CID Patcher Tool will generate a new CID with the updated SN and the correct CRC-7 value. This new CID must be copied for the next stage in the patching process.
Steps to copy the new CID:
- Review the new CID generated by the tool.
- Copy the complete CID, ensuring that no errors are made.
- Store the new CID in a safe location for easy access.
The new CID will now be used in the final patching process with tools like UFI Box or Easy JTAG Plus.
Patch the CID with Easy JTAG Plus:
Now that you have the new CID, it is time to patch it onto the eMMC chip’s firmware. This can be done using software like Easy JTAG Plus, which is commonly used for flashing and repairing eMMC chips.
Steps to patch the CID using Easy JTAG Plus:
- Connect the device’s eMMC chip to the Easy JTAG Plus software.
- Load the new CID into the software.
- Use the software to write the new CID to the eMMC chip.
It is essential to ensure that the firmware is compatible with the new CID before proceeding. If the firmware does not match, it could lead to device malfunctions or a bricked device.
Patch the CID with Medusa eMMC Firmware:
The Medusa software offers another method for patching the CID onto the eMMC chip. This process is similar to Easy JTAG but involves using the Medusa firmware tools.
Steps to patch the CID using Medusa:
- Create the new CID using the same process as described earlier.
- Connect the eMMC chip to the Medusa software.
- Load and write the new CID onto the chip using the Medusa tool.
The Medusa software provides another way to flash the CID if Easy JTAG is not available or preferred.
