The most critical patch. The patched version allows reading and writing of eMMC chips up to 128GB and beyond. This means you can now create a full-disk image of a 64GB Android TV box without splitting files.

Even with the patch, users encounter problems. Here is a quick troubleshooting guide.

Problem: "Device not found" in software, but box lights up. Solution: Reinstall the custom MK_MMC_Driver included in the patched ZIP. Disable driver signature enforcement in Windows.

Problem: Write operation freezes at 99%. Solution: This is a known v31 bug regarding the partition's G.P.T. (GUID Partition Table). Use a hex editor to zero out the last 512 bytes of your dump file and rewrite.

Problem: The box works for 10 minutes, then disconnects. Solution: The patched firmware sometimes bypasses the thermal regulator. Your box is overheating. Attach a heatsink to the main IC on the MK box.

Problem: "CRC Error" when verifying. Solution: Lower the clock speed from 80MHz to 40MHz in the advanced settings. Your ISP wires are too long or have poor signal integrity.


The MK eMMC Plus is not a standalone device; it relies on a Windows-based GUI (Graphical User Interface) to execute commands like "Read," "Write," "Erase," and "User Area Partitioning." The version number "v31" typically refers to the firmware version of the box or the accompanying software version. This software is often locked to prevent unauthorized use or to restrict capabilities based on licensing.


Low-cost Android TV boxes use cheap eMMC chips prone to corruption. The patched version is highly sought after because these chips often lack proper manufacturer IDs. The v31 Patched ignores the whitelist, allowing users to flash generic fastboot images.

Given the popularity of this tool, malware-laced fake versions circulate on forums. A genuine MK eMMC Plus V31 Patched release has these characteristics:

Warning: Download only from trusted sources. Avoid "crack sites" offering the patched tool bundled with keygens, keyloggers, or miners.


Stock V31 only accepts a whitelist of USB VID/PID pairs. The patched version removes these checks, allowing the tool to work with generic USB-to-SD adapters, eMMC adapters (like the FMC-MSD-808), and even direct SD card reader connections (with proper wiring).
