Troubleshooting Reinstall Duo
Troubleshooting section dedicated to the MOD Duo.
MOD Duo Factory Reset
For a factory reset using Windows, see Troubleshooting Reinstall via LiveSuit. (applies only to older MOD Duo units with nand flash)
For a factory reset using Linux or macOS see Troubleshooting Reinstall via CommandLine.
A note on different models and old kernel
Please note that there are 2 different kinds of MOD Duo units - older ones with nand flash and newer ones with eMMC.
The new unit models have their name (like "MOD Duo") written and engraved above the right display.
Since version 1.10, we changed the kernel used by the Duo, but this update only automatically applies to new unit models.
For the older models, we need to either do a special update step, or a full factory reset.
In both cases the disk contents (user data) is completely wiped out.
You can check which kernel version you are running by looking at the "System information" in the advanced settings.
Kernel release 5.4.38-rt21-modduo is the newer one, while 3.4.104-rt139-modduo is the older one.
The new kernel offers better performance and reliability, so you are still using the old one please update!
Special update for nand units
NOTE: Only for older MOD Duo units with nand flash. MOD also recommends doing a MOD Duo Factory Reset instead of this special update.
In order to make older MOD Duo units switch to the new kernel we can use a special update file.
This was created mainly for those users who are using Windows or are not comfortable with the command-line.
Please do not power off your unit once the procedure has started!
To begin:
- Put the unit into recovery mode. See Releases if you need help on that.
- Download this special update file modduo-convert-nand_20201028.tar
- Install the tar file in the previous step, and wait until the unit boots itself again in restore mode (this might take a few minutes)
- Install a MOD factory reset image from the Factory Reset Images section.
- Wait until the MOD sets leds green and reboots itself
