Good job. Probably we may borrow both the GPS/camera Hal's and vendor from R3 and try

 

[pirej]

Probably(hopefully) yes, but we will see.

 

[s.sawrav]

Woohoo

Yay 64 in the House :laugh:

@pirej can you share your kernel source here again? Also, how which tool you used to unpack-repack the boot.img? can you tell me the process? I'm having issues only with this in here

 

[Mr Smith1]

wow,I am waiting it becomes stable

 

[pirej]

As i told you, Im not repacking anything, its all build from source.
But when i need pac/repack.. i use this on linux or this on windows.

Hey, why do you ask same question again? He's building from source, not packing, unpacking boot.img. Go and get sources link from previous post and there are tons of methods in xda on unpacking boot.img.

Look, I asked him again becouse I tried using a lot of methods for making the boot.img, BUT it dosn't work, when I compile the kernel all I get is the kernel.gz and the dt.img, I need the ramdisk for caf that is on the boot.img, I can unpack-it, but I can't repack-it, it will give me an error saying that it can't find mkbootfs and mkbootimg, even that they are on the location indicated Mkboot , that's why I'm asking for help

 

[youngAvJ]

awesome work bro.

 

[LuanHalaiko]

@pirej , my device model is wrong, it's showing the 2014811 model, but my model is 2014819, any way to fix it? but I don't think this is too much important

 

[valenrock]

Not boot here. Clean flashed install..

 

[Saurabh_Umadikar]

Booted successfully on my HM 2014818 (Indian Variant).

It just misses out on Camera , Non remappable H/W keys and GPS which will be fixed by pirej ? soon™.

It takes an atypical amount of time for the first boot to happen. Be patient.
