Last updated: November 10, 2026. Short answer: Maui META (also called Modem META or SP META) is MediaTek’s Windows tool for repairing the modem calibration (NVRAM) and restoring the original IMEI on MediaTek phones. The newest version is the Modem META v10.2340 line. For older Xiaomi and Redmi phones (Helio X10/X20, P-series, G25/G35) the classic v9.1635 and v10.1816 builds below still work best. Newer Dimensity phones on HyperOS usually block META mode for unauthorized tools.

How to restore the IMEI with Maui META
- Install the MediaTek VCOM and CDC drivers, then install and open Maui META.
- Choose Options → Connect smart phone into META mode and select USB COM as the connection.
- Click Reconnect. Then connect the phone switched off. If it isn’t detected, hold Volume Down (on some models Volume Up) while plugging in the cable.
- When the status turns yellow/green, choose IMEI download from the drop-down list.
- Load the modem database: click Change NVRAM DB and select the
MDDB/BPLGUfile from your phone’s stock firmware (inside the modem image of the Fastboot ROM). Some versions read it from the phone automatically. - Enter the original IMEI 1 and IMEI 2. Depending on the version, type all 15 digits or the first 14 with the check digit calculated automatically. Then click Download to flash.
- Disconnect with Disconnect from target, reboot and check with
*#06#.
Common problems
- Stuck on “Searching for META port”: driver issue. Reinstall the VCOM driver, try another USB 2.0 port, and connect the phone fully off.
- “META connect failed” on new phones: Xiaomi locks META mode on recent MediaTek models. Maui META can’t bypass it.
- IMEI shows “null” after flashing: often fixed by flashing the full stock ROM for your region (it restores
nvdata) before touching Maui META. Get it from our firmware hub. - Snapdragon phone? Maui META doesn’t work on Qualcomm chips. Use QPST instead: backup and restore IMEI with QPST.
FAQ
What is the latest Maui META version?
MediaTek’s tool is now called Modem META. The newest public builds are in the v10.2340 series. For older Xiaomi and Redmi phones, v9.1635 and v10.1816 are the most reliable.
Does Maui META work on Windows 11?
Yes, as long as the MediaTek VCOM driver installs. On Windows 11 you may need to turn off driver signature enforcement once to install the older driver.
Is Maui META safe?
The tool itself is MediaTek’s official engineering software. Writing the wrong NVRAM database or another phone’s IMEI can break the modem, so back up first. Only use it to restore your own phone’s IMEI.
