#Can't boot userland B on n0120

I have a NumWorks n0120 calculator(epsilon 23). Trying to build and flash a custom userland (B), using this command:
make clean
if [ "$(python3 build/device/dfu.py -l | grep '0x90000000')" ]; then make userland.A.dfu; python3 build/device/dfu.py -s 0x90010000:leave -D output/release/device/n0110/userland/userland.A.dfu; else make userland.B.dfu; python3 build/device/dfu.py -s 0x90410000:leave -D output/release/device/n0110/userland/userland.B.dfu; fi;

But the userland B doesn't ever boot up, nor do I have external .nwa apps working. Any help?

Try this command instead : if [ "$(python3 build/device/dfu.py -l | grep '0x90000000')" ]; then make MODEL=n0120 userland.A.dfu; python3 build/device/dfu.py -s 0x90010000:leave -D output/release/device/n0120/userland/userland.A.dfu; else make MODEL=n0120 userland.B.dfu; python3 build/device/dfu.py -s 0x90410000:leave -D output/release/device/n0120/userland/userland.B.dfu; fi;

(you are flashing an N0110 binary on your N0120)

Still nothing

should I do this with the calculator booted up or from a recovery?

I had the same problem and just solved it. These are the steps I followed:

  1. Install the official software
  2. Open the terminal, navigate to your epsilon folder and type the command used by Yaya.Cout. (Simply connect the calculator to the computer, as if you were transferring a python script)
    3.The calculator will restart in the slot where the custom userland was installed.
