Yes, but there hasn't been anything open source since the release of the device in 2016. There were a lot of people starting DIY Pokemon GO plus device, but all of them were stumped by the certification protocol.

Ah, you have found a bug in my code (I made an error in computing the string length, and didn't notice it because it displayed fine on Chrome). I have fixed my code in git and the blog post.

-Wl,-z,norelro

e.g:

gcc -Wl,-z,norelro test.c
