* I am not responsible for bricked devices, dead SD cards,
* thermonuclear war, or you getting fired because the alarm app failed. Please
* do some research if you have any concerns about features included in this ROM
* before flashing it! YOU are choosing to make these modifications, and if
* you point the finger at me for messing up your device, I will laugh at you.
*/

Gaaps are not included, open_gapps-arm64-7.1-pico works fine.

The ROM supports signature spoofing, so you can use microG as a "replacement" for gaaps.

@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

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

    I have other real "life bugs" to solve, and that doesn't leave me any space for this any more.
    Im still using the Redmi2 daily with this caf rom, but im using it just as a smartphone, not a test device, i haven't even rebooted the phone for months :)
    Its been a fun journey coming from kitkat, making roms and kernels without official kernel sources at all, and everything worked(more or less) at the end.
    BIG thanks to all of the XDA members that supported my work and the development of Redmi 2 in general, and GIGANTIC thanks to balika011, the guy who put everything together to make the FIRST public kernel sources that worked for Redmi2, and everything after that was easy.
    There were other big contributors to the development too, but i wanted to mention the one that everyone forgot about, and probably 80-90% of the redmi2 users don't know that HE was the one who made it possible, not some low lives like me, or some self proclaimed "developers".
    Redmi 2 has proven to be a very potent device, very convenient for development, and i will buy Xiaomi phones because of that experience.

    Thanks again, pirej.
