Honor 7A DUA-L22
Can I port this os at my device?)
@dimakoloda Info is here https://forums.ubports.com/topic/2068/halium-first-steps As you have not started a port yet I am moving this to Off Topic.
Also, Huawei and Honor devices are generally locked down by Huawei, I doubt you will find ways to root it, and then have all necessary sources. Is there a LineageOS version for your device?
