What a hero! Trying to craft alone a 12 layer PCB without any FP2 documentation available to him. I’m worried that after two months of amazing work and 136 messages in his thread about this very interesting effort, he says he is stuck because he has not been able to contact any Fairphone employee. Is the company reading that thread? Is the company supporting that effort? Is this project OK for the company’s roadmap and marketing? I’d love to know.
(By the way, I should ask this guy to add Galileo support to his board! 
)
You have convinced me however that specially the community but also the company showed more interest than some other companies in extending the lifespan of this device more than the typical 2.5 years (not like in their first try with FP1, when they didn’t own the design). I wish I could know how long they will keep that support. I also wish this hero could had the same support that the company itself had (according to @AnotherElk) when they wanted to develop that Android upgrade!
