Restore access to a unifi controller

When you are unable to login to the unifi controller or forgot admin password, you can restore access using SSH and manipulating mongodb directly.

Warning

Do not uninstall unifi controller - most of the data is not stored in mongodb. In case you thought a mongodb backup would be sufficient, you may have fucked up already, just like me. However I managed to write this "tutorial" for anyone to not run into the same trap.

Apparently this guide no longer works with recent unifi controller versions (starting nov/dec 2022). Since I no longer use unifi hardware in my home system, I can not update the guide myself. In case you've gotten here to recover your data, you're likely doomed. But giving it a try won't hurt anyway, therefore: good luck.

# My usecase was to get the custom virtualenv prompt name from
# python virtualenvs created by poetry and virtualenv package.
# Builtin venv puts the prompt value also into environment variable
# called VIRTUAL_ENV_PROMPT that makes my life much easier.
# Virtualenv guys recommend to use pyvenv.cfg

imx8mn has an extra cortex-m7 core. you have few options for starting it

1. use downstream imx-atf and mainline u-boot bootaux command
2. use upstream atf and poke at the registers manually

For option 1 you can follow the AN5317 app note and things should work out fine

fatload mmc 1:1 0x48000000 hello.bin
cp.b 0x48000000 0x7e0000 $filesize
bootaux 0x7e0000
