i cant compile on this pc
Has anyone compiled it for the I9195?
if so can i have a copy please as i cant get to my own pc until the weekend.

 

[sasank360]

i think we have to compile it ourselves.

 

[LaShto34]

Having in mind the fact that 99% of us won't even dare to think about installing a kernel compiled by ourselves, is there a chance for someone more experimented to compile this kernel for all 3 versions?
I personally only need the lte version, but...
Thank you in advance.

Can not compile (newbie)

I would love to test this kernel and give feedback but I have no knowledge on how to compile. What's the chances on someone doing this with experience? I'm after the LTE version myself, I'm excited for a new kernel to play with. Or maybe someone can send meva walk through guide on his to compile.

Thanks in advance

 

[savvy1968]

Has anyone tried it yet?

Any luck yet bud?

 

[haloass65]

I wanna test the Gaming performance and compare the results with the lombartz kernel

 

[Kelvin BR]

improves battery?

 

[savvy1968]

Well i think thats the end of that.

Kernel is not stable, so we must wait. Patience, patience and one more time patience

Could you update the OP so we all know what we are waiting for, change (stable) to its current title etc etc, all I'm seeing is disinterest in this thread. Maybe release a pre-release version so someone else can help you, there is no point to compile this myself or I might as well start my own thread.

Looking forward to your clarification and thanks in advance.
