First, i have pushed public update for 3.5 kernel.
* Merged linux code update from 3.18.137 to 3.18.140.
* Merged mega patch for F2FS file system driver.
works great for me LOOOONG time with 0 issues. so why not to share
Now about moving to oreo, forget it, it's pointless. OP3 is best with Nougat, it's just works, why bother with more pain in *****
I have seen OP7Pro and it's looks great, i am already locked on it, with the 8GB or 12GB ram... the price is high right now, so i will wait for few months before buying it.
About kernel for it, i hope i can move some of the things i like to OP7, all i know it's way far away from 3.18.x, it's will be challenging
My free time is not what used to be, i cant promise much, and i am sure there are many "young/Pro" awesome kernel devs that are doing great job with there builds.
I will be around, on lookout for new patches in main line for this kernel, till switching to new phone in future.
