Pre-Installation FAQ

Q: Will this guide void my warranty ?

A: No, at least not in europe. This is a software modification, if Numworks refuses you a legitimate warranty claim after that, sue the fuck out of them.

Q: How risky is jailbreaking my Numworks?

A: Full on hardware bricks are quasi-impossible. The worst you can get is a calculator with write protection enabled with an empty flash, which can always be solved with a hardware mod, but the chance of having that kind of issue is very very unlikely.

Q: Can I do this without a computer (e.g. an Android phone)?

A: All you need is a device capable of running a web browser supporting WebUSB. Android phones can be used with an USB OTG cable.

Post-Installation FAQ

Q: Is it safe to update Epsilon while having a Custom OS installed ?

A: At the moment, Numworks' installer doesn't check for modded bootloaders, neither does Epsilon, so yes (unless you don't have a bootloader which is probably not the case).
