DOWNLOAD IMAGES FROM: https://developers.google.com/android/images

1. Installing dependencies​

sudo apt-get update
sudo apt-get install p7zip-full p7zip-rar
sudo apt-get install simg2img
sudo apt-get install git

2. Extract factory image and get system.img, place on any folder and run:​

simg2img system.img system.img.raw

mkdir ~/AndroidWorkspace
cd ~/AndroidWorkspace
git clone https://github.com/erfanoabdi/Capire-Le-Treble.git
git clone https://github.com/erfanoabdi/P_semiGSI.git
git clone https://github.com/erfanoabdi/ROM_resigner.git
git clone https://github.com/LineageOS/android_build.git -b lineage-16.0

mkdir system
cd system

To mount the image, go to system.img.raw image folder

sudo mount -o,noatime system.img.raw ~/AndroidWorkspace/system

3A. Build for A-Only​

cd ~/AndroidWorkspace/Capire-Le-Treble/Extra
sudo ./sGSI-ify.sh ~/AndroidWorkspace/system/system 2147483648 ~/AndroidWorkspace/sGSI_A.img

Wait until you see: “Press any key to continue”

Open new tab, then:

cd ~/AndroidWorkspace/ROM_resigner
sudo python resign.py ~/AndroidWorkspace/Capire-Le-Treble/Extra/tmp/system ~/AndroidWorkspace/android_build/target/product/security
cd ~/AndroidWorkspace/P_semiGSI/systemimgmaker
sudo ./make.sh ~/AndroidWorkspace/Capire-Le-Treble/Extra/tmp/system

Back to older and Press any key to exit

3B. Build for A-Only​

cd ~/AndroidWorkspace/Capire-Le-Treble/Extra
sudo ./sGSI-ify_ab.sh ~/AndroidWorkspace/system 2147483648 ~/AndroidWorkspace/sGSI_AB.img

Wait until you see: “Press any key to continue”

Open new tab, then:

cd ~/AndroidWorkspace/ROM_resigner
sudo python resign.py ~/AndroidWorkspace/Capire-Le-Treble/Extra/tmp/system/system ~/AndroidWorkspace/android_build/target/product/security
cd ~/AndroidWorkspace/P_semiGSI/systemimgmaker
sudo ./makeab.sh ~/AndroidWorkspace/Capire-Le-Treble/Extra/tmp/system

Back to older and Press any key to exit

Fixes​

SELinux folder (by GabrielHoward)​

  • Downlaod
  • Path: ~/AndroidWorkspace/capire-le-treble/extra/tmp/system/etc

Remove selinux folder and replace with the new one

Give permission to tmp folder:

sudo chmod -R 777 tmp

Error unexpected (in building..):​

go to: ~/AndroidWorkspace/psemigsi/systemimgmaker/in.sh

put a ! in front of # (should be like this: #!/bin/bash)
