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 ges 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.
Q: Is it safe to update Epsilon while having Phi installed ?
A: At the moment, Numworks’ installer doesn’t check for modded bootloaders, neither does
Epsilon, so yes.
To update Epsilon after installing the Phi bootloader, you can just hold 4 while pressing reset to access the
softloader and go on Numworks’ website. From there, just update Epsilon normally.
