I got FATAL: kernel too old error on Ace 2, android Jellybean kernel 3.0.31.

I've follow all the instructions to install the busybox, not every command I use is command not found, so, what is the proper way to use it?

I have a LG X Charge with Android 7.0 kernel 3.18.31, security patch Nov 6, 2017
and I get access denied try to cd to the directory. I got busybox not found.
H=$PATH:/data/user/0/exa.free.bbin/files <
H=$PATH:/data/user/0/exa.free.bbin/files <
lv7:/ $ echo $PATH
/vendor/bin:/system/bin:/system/xbin:/data/user/0/exa.free.bbin/files:/data/user/0/exa.free.bbin/files
lv7:/ $ busybox
/system/bin/sh: busybox: not found

/system/bin/sh: cd: /data/user/0/exa.free.bbin/files: Permission denied

The project does not build with gradle 5.4.1 via command line (no Android Studio IDE):

Build file 'C:\Users\fnajmi\github\Busybox-Installer-No-Root\app\build.gradle' line: 1

* What went wrong:
A problem occurred evaluating root project 'app'.
> Plugin with id 'com.android.application' not found.

Its unclear what version of gradle works with teh project.
Need to include gradle warpper with the right version in gradle-wrapper.properties to address this.

TIA for adding gradle-wrapper to project or at least updating REDAME.md to indicate which version of gradle works with project.

@Alsan Here's what I type in the terminal (please do not type the leading $ , it's my shell PS1 prompt) :

$ [ "$HOME" = "/" ] && export busyBoxPATH=/sdcard/Android/data/exa.free.bbin/files || export busyBoxPATH=$HOME/Android/data/exa.free.bbin/files
$ ls $busyBoxPATH/busybox
/sdcard/Android/data/exa.free.bbin/files/busybox
$ export PATH=$PATH:$busyBoxPATH
$ busybox --help

Hey I just did a fresh boot of my firmware on my S10 android 12. No root, no frp, no Samsung or Google accounts but alliance shield is device owner. I'm using com.draco.ladb for adb shell and tried shizuku with inure shell. Anyways, they're not allowing me to cd into /data/data/*******/blah.blah.blah. are there any system apps or anything I can do to get busybox mounted in system or am I still calling google "daddy" and being its bitch? Not enjoying this not being able to root or even become superuser for my device. It's a snapdragon so bootloader is out of the question unless someone else has any ideas... thanks (if anyone even reads this)
