Jhuan Reategui Solis

I design and build software, and in my spare time I bring old phones back to life: CyanogenMod ports, recoveries, kernels and bootloader reverse engineering.

GitHub Android projects

Android ports

Phones nobody updates anymore, running again: ROMs, recoveries and kernels built from source.

Tools

What I needed along the way to test, document and publish that work better.

Hardware and research

Bootloaders, device recovery and hardware fixes, always tested on the real device.

Software development

Mobile and web applications, plus plugins for the community.

Experience and education

Over eight years building software for companies, banks and startups, and teaching it; before and alongside the Android ports.

About

I work as a software architect, I teach and I serve as a catechist. I like to explain what I build: every port I publish states its real status, the tests done and what still does not work.
