So, I've discussed with some people I know and there is at least the will to try to develop something. @javelinanddart made some nice kernels for my old device and he wants to make a CM ROM for S6 Edge. I know there were other attempts and I know they failed (at least here I couldn't find anything else).
He needs testers...and when I say tester I mean no newbies or users that just want to be cool..real, good testers. Someone who's able to flash and test kernels and ROMs, someone who has some medium to advanced knowledge and of course knows how to flash, take logcats and things like that. So don't jump in if you think you're not qualified. Devs are more than welcome to join this if they want to.
We would like to start a specific Hangouts chat for that to be easier to communicate, there will be NO public releases untill at least a bootable build is made. As with any other development, there is a small risk of bricking the device if something goes wrong but that's a risk we all know and accepted when we start flashing. So once again, THIS IS NOT FOR NEWBIES, please don't even think about asking to be a tester if that's the case.
If there is anyone interested, please let me know by posting here and send your Hangouts contact via PM (I don't want to have a public disclosure of personal info)
Also if there is detailed info about development for this device like kernel sources, device trees, vendor files and so on, please post the GITHUB links, it'll help the development.
