@arunkumar413 First have a look here https://forums.ubports.com/topic/2068/halium-first-steps/1 for some basic info. After that if your device is suitable we can provide plenty of help and advice to help you complete your port.
We also have a telegram porting group (will find the link later) for more help and advice. The first step is for you to check the compatibility of your device.
@Nic264 Hi,
no problem. If you got any meaningful changes or improvements in the code, consider forking the repos and pushing your changes into those new repos.
