Some versions of Windows do not support case sensitive so you need to install Windows Subsystem for Linux(WSL). This can be done from CRB.

Setup
1. Install CRB onto the C: drive.
2. Go to Windows Settings and make the CRB folder an exception for virus protection.

3. Run CRB as Administrator.
4. Import Distro
5. Test Distro
6. Install WSL
7. Reboot Windows
8. Look at videos in help folder

Run CRB as Administrator.

Create new project
Extract ROM (auto)
or Extract ROM (selective)
extract apxxxxxxxxxmd5

Make any changes to the system folder found in the ROM folder
- edit build.prop to change ROM name
- add apps to system/priv-app

Build image
choose system
then choose vendor

The zip creator is not complete but you can still flash the ROM onto your phone

The 3 files you need are
build/system.img
build/vendor.img
source/boot.img

Take these files to your phone
and either flash them individually from TWRP
or
rename system.img to system_new.img
and rename vendor.img to vendor_new.img

insert them into my CRB-installer.zip
