**Professional NAND/eMMC Chip Reader/Writer with Windows Software—Hardware Tool for Repairing Mobile Phones and In-Vehicle Infotainment Systems**

> The compressed file contains two main programs:
> 
> 1.  `EasyJtag_Release_v3.7.0.20.exe`: EasyJtag main program
> 2.  `easyjtag_emmc_plus_1.6.4.0.exe`: EMMC Plus module program `latest_shell.exe` is the shell launcher

## ✅ Core用途 (Automotive repair scenarios, compatible with MIB/MHI in-dash units)

1.  **Reading and writing to eMMC / NAND flash chips** Remove the eMMC storage chip from the in-vehicle infotainment system’s motherboard to read a complete image dump, back up firmware, erase the chip, and write a new system image. Frequently used for repairing Volkswagen and Audi MIB, MHI, and MOI3 infotainment systems.
2.  **Unlocking and Repairing In-Car Infotainment Systems** Bricked system recovery, removing device locks, repairing damaged partitions, flashing custom firmware, and reading internal EEPROM data from the infotainment system.
3.  Smartphone Repair: Reading and writing character sets on Android phones, brick recovery, and account lock removal (one of the most essential tools for smartphone repair)
4.  Supported chips: eMMC, NAND, UFS (select versions); supports BGA-packaged font chips

## Hardware Compatibility Notes

**The software cannot be used on its own; it must be used in conjunction with the EasyJtag Plus hardware programmer**, connecting to BGA character set chips via a probe socket, soldered chip socket, or jumper wires.

-   Workflow: Remove the chip → Place it in the programmer socket → Open the EasyJtag software on the computer → Read and write the character library image.

## Differences from the automotive repair tools mentioned earlier

-   BAVCalc: Software-only solution for calculating passwords and anti-theft codes
-   EasyJtag: **Software that works with hardware to directly read and write the original firmware image from the memory chip**. It is used to dump the in-car infotainment system’s character set; once the .bin file is obtained, tools such as BAVCalc or DaVinci can be used to process the data within it.
