How to Find Suitable Flash Memory for MTK SoC

How to Find Suitable Flash Memory for MTK SoC

For your MediaTek (MTK) System-on-Chip (SoC) to function properly, selecting the right kind of flash memory is necessary. Finding the Product Name (CID) is one of the most important steps in choosing compatible flash memory. We'll walk you through each stage of the procedure below.

Understanding Product Name (CID)

• LUN0 and LUN1 (Bootloader Partitions)

• Same Preloader Requirement

• LUN0 and LUN1 Preloader File Type

These components ensure the device can boot properly and communicate effectively with the flash storage.

How to Find the Product Name (CID)

You can use a number of tools and methods to properly identify the flash memory's product name. Some of the best methods are listed below:

1. Using CM2 MTK Helper or Preloader Parser

• CM2 MTK Helper is a tool that allows users to extract preloader details from a MediaTek device.

• Preloader Parser can also be used to analyze and determine the flash memory specifications.

2. Using a Hex Editor

• A Hex Editor can be used to manually inspect the preloader file and locate the necessary CID information.

• By examining specific memory addresses, you can extract the product name and other relevant data.

Changing MTK Flash Memory Without CPU

The CPU does not need to be replaced in order to replace the MTK flash memory. For an operation to be successful, though, you need to make sure:

1. Product Name Compatibility – The new flash memory should have the same CID as the original.

2. Des (Description) – Understanding the specifications of the flash memory.

3. Att (Attributes) – Checking the key attributes of the flash memory, such as read/write speed and compatibility.

4. Dumping Data – Creating a full dump of the original flash before making any modifications.

Easy Fixes & Precautions

• Backup NV Data: Always ensure you back up the NV (Non-Volatile) data before making any changes. Losing NV data can lead to issues like IMEI loss, network problems, or device bricking.

• Use Compatible Flash Memory: Avoid using non-compatible flash memory, as it may result in boot failures or system instability.

• Verify Preloader Matching: Always ensure the preloader matches the new flash memory to avoid issues during the boot process.

By following these steps, you can successfully identify and replace MTK flash memory while ensuring device stability and performance. Happy flashing!
