Step-by-step instructions to build a smartphone that is open-source, upgradeable, repairable, and Big Tech free

The project is really cool! It is definitely a proof of concept and the next step with computing module 4 must be much slimmer and easier to assemble

Amazing contribution to open hardware

Why the down votes on this? I had a quick look at the github repo and it looks pretty neat to me. I must be missing something...

Anyone care to enlighten me?

There’s a long history of people saying you can never have an open source phone because GSM radios and baseband stack or whatever need costly FCC approval. I also thought it was in the GSM spec that carriers had to be able to update some part of the baseband OS spontaneously. So I wonder how they got around that.
