Restore Stock Firmware

danger

Restoring your calculator to stock firmware WILL LOCK IT and you won't be able to install any Custom OS on it ever again, unless you use a hardware method to unlock it again. We highly advise using the bootloader from any compatible Custom OS and install Epsilon from softloader to still use the latest versions without locking your calculator.

This page will tell you how to go back to a fully stock firmware and therefore locking your calculator.

1. Open NumWorks' restore page.
2. Put your calculator in Recovery Mode holding 6 and pressing "RESET" at the same time.
3. Plug your calculator to your computer.
4. follow the instructions to restore stock firmware.

You now have a fully stock NumWorks calculator.
