MediaTek firmware dumper for Linux

Currently only for MT6260/MT6261 chipset. You can edit the code to work with other MediaTek chipsets.

  • THE SOFTWARE IS PROVIDED "AS IS", WITHOUT WARRANTY OF ANY KIND, USE AT YOUR OWN RISK!

Instructions

  1. Initialize the USB serial driver:
$ sudo modprobe ftdi_sio
$ echo 0e8d 0003 | sudo tee /sys/bus/usb-serial/drivers/generic/new_id
  1. Run this command and connect your device to USB:
$ sudo ./mtk_dump connect  show_flash 1  read32 0 0x400000 dump.bin
  • Where 0x400000 (4MB) is the expected length of flash in bytes (may be more or less).
  • An example payload is here (you can read the BROM with it).

Using the tool without sudo

If you create /etc/udev/rules.d/80-spd-mtk.rules with these lines:

# Spreadtrum
SUBSYSTEMS=="usb", ATTRS{idVendor}=="1782", ATTRS{idProduct}=="4d00", MODE="0666", TAG+="uaccess"
# MediaTek
SUBSYSTEMS=="usb", ATTRS{idVendor}=="0e8d", ATTRS{idProduct}=="0003", MODE="0666", TAG+="uaccess"

...then you can run mtk_dump without root privileges.

  • As you can see this file for both Spreadtrum and MediaTek chipsets.

Using libusb to connect

You can build the tool with libusb method: make LIBUSB=1

For Linux users, this method doesn't require the ftdi_sio kernel module, but libusb/libusb-dev packages must be installed.

For Windows users, this method is the only one available, should also require drivers (the same as needed for flashing tools).
