Troubleshooting Reinstall via CommandLine
Troubleshooting Reinstall via Command Line
Requirements: Linux or macOS, basic command-line knowledge
For a factory reset under Windows, see Troubleshooting Reinstall via LiveSuit. (applies only to older MOD Duo units with nand flash)
To begin:
- Make a backup of your MOD Duo
- Click and hold down the FEL button on the back of the MOD Duo (in tiny hole), while you power it on.
- Hold it for 2 seconds, then release (The screens will freeze with the MOD logo and name)
- Connect the MOD Duo to your computer via USB cable
- Download this file: https://download.moddevices.com/releases/modduo/tools/duo-nand-mainline-factory-reset-v2.tar.gz and extract it
- Open a terminal and 'cd' to the directory where duo-nand-mainline-factory-reset-v2.tar.gz was extracted, ie:
cd ~/Downloads/duo-nand-mainline-factory-reset-v2
Now simply run:
./boot-fel-factory-reset.sh
(sudo will likely be needed here)
If the above command fails with "USB FEL device not found", try a different usb port of the computer. It might not work with usb hubs or usb-type-c/thunderbolt adapters, so connecting directly to a USB port is preferred..
For non-64bit Linux systems, use the sunxi-fel binary from your distribution.
Continuing:
- After the script finishes, wait for around 1 minute and the MOD Duo will boot into recovery mode. (confirmed by LEDs turning blue. note that sometimes the display does not change)
- Install a MOD OS factory reset image.
- Wait for the installation to complete (the unit will restart automatically).
Note: You can find MOD factory reset images in the Factory Reset Images section.
