I'm trying to compile a kernel for my J7 PERX, trying to get a device tree for a custom LineageOS rom, I'm following the readme samsung provided and when I run "./build_kernel.sh" it says it can't locate "aarch64-linux-android-gcc" I've got if pointed at the cross-compiler location in the makefile. I'm asking for any assistance I can get at this point.

[UTIL] Android Software Detonator - Software to speed up reverse-engineering

I was struggling to create clear folder structure for maintaining reverse-engineering projects. Also doing everything manually took that much time I preferred not to compile app and read .java files of cracked application just to check that I didn't break anything while working with Smali. That's why I created this project. The code is mostly uncommented but I have made it pretty easy to read if you know basics of Ruby though I'm thinking about commenting it soon.
The software is Linux only at this moment since I'm lazy, I don't like Windows and there is no good reason to prefer Windows over Linux while reverse-engineering.

I hope you enjoy, report bugs and contribute. And as always I'm not responsible of your acts and this shall not be used for apps that you don't have permission to reverse-engineer!

kernel development

Xperia M2 D2306
Android: 4.2.2
Bootloader Unlocked: Yes
Development kernel with linux mint & Windows 8.1
I gained some knowledge about android much as modifications and scripts that perform specific actions
Using OS Linux Mint eh I could decompile the boot.img file

I had access to the script can be seen from root explorer in the path: /
But investigating more thoroughly about modifications cpu frequencies are situated on the zImage file
The question is how descompile the zImage?
some tutorial
Now as if there will be an issue that can continue to decompile the kernel when the same can now add the root with its binary respective
thank you for your help
Will you people ever learn about posting in correct threads?
I do not but I need to know the subject well because I can do what I want with my kernel
You cannot decompile zImage. That's why there's GPL to enforce releasing sources.

[Completed] Unlocking the boot loader and building a custom recovery not working Lenovo A7-30F

First when I tried to unlock the bootloader of the a7 it returned "..." when I did fastboot oem unlock. then I tried fastboot oem device-info to try to see what was wrong and it returned "...". After that I tied to make twrp for the device with this guide and successfully installed the omni sorce code but I now have no idea how to get my manufacturer files from. I built CM before but the cm source already had the oneplus manufacturer files.
