building AOSP for Intel Platform(NEED HELP) - Android Q&A, Help & Troubleshooting

Actually I have read so many topics about building Android Open Source Project for Intel based platform , they are such Android X86 , OS Remix and AOSP_IA (AOSP for Intel Architecture).
Now I want to build an AOSP for my tablet which is based on Intel Atom ( Z3735F), 10.1 inches display , 2 GB RAM and INSYDE UEFI bios type , device codename :inet_phone_32
My tablet runs Android 5.1.1_r1 (AOSP_AI TYPE) , there is no back up or rooting technique for this tablet ,so I decide to build an AOSP ROM for this tablet ,if the Android OS has a problem , I am able to flash it again and survive it.
I have tried in 3 ways to build an AOSP for my tablet but no one is correct so, I need an android developer or android expert to guide me and modify my mistakes .
According to google source :
these are steps for building AOSP for a device :
1. install , Java 8 ,git, curl , ($ sudo apt-get install "App")
2. Setting up ccache
3. install repo
$ mkdir ~/bin
$ PATH=~/bin:$PATH
$ curl https://storage.googleapis.com/git-repo-downloads/repo > ~/bin/repo
$ chmod a+x ~/bin/repo
4. creating working Directory
$ mkdir WORKING_DIRECTORY
$ cd WORKING_DIRECTORY
5.git configuration (name and email)
$ git config --global user.name "Your Name"
$ git config --global user.email "[email protected]"
6.inititilized repo and download the proper ROM
$ repo init -u https://android.googlesource.com/platform/manifest
$ repo init -u https://android.googlesource.com/platform/manifest -b android-5.1.1_r1
$ repo sync
7.$ . build/envsetup.sh
8. choosing the target
$ lunch inet_phone_32-userdebug
9.$ make(m) -j4-efi
Click to expand...
Click to collapse
unfortunately , it wont flash on my tablet !
According to Android X86 : these are steps for building an AOSP_X86
1. install , Java 8 ,git, curl , ($ sudo apt-get install "App")
2. Setting up ccache
3. install repo
$ mkdir ~/bin
$ PATH=~/bin:$PATH
$ curl https://storage.googleapis.com/git-repo-downloads/repo > ~/bin/repo
$ chmod a+x ~/bin/repo
4. creating working Directory
$ mkdir WORKING_DIRECTORY
$ cd WORKING_DIRECTORY
5.git configuration (name and email)
$ git config --global user.name "Your Name"
$ git config --global user.email "[email protected]"
6.inititilized repo and download the proper ROM
$ repo init -u http://scm.osdn.net/gitroot/android-x86/manifest
$ repo init -u http://scm.osdn.net/gitroot/android-x86/manifest -b lollipop-x86
$ repo sync --no-tags --no-clone-bundle
7.$ . build/envsetup.sh
8. choosing the target
as it was said on Android X86 instruction :
$ lunch android_x86-userdebug
9.$ make(m) -j4-efi

Click to collapse
unfortunately , it also wont flash on my tablet !
According to Android on Intel Platform , these are below steps for building AOSP_IA:
Dependencies:
Follow initial steps from here: https://source.android.com/source/initializing.html
Additional Dependencies:
