Almost all the OTA's that I provide will be Delta OTA's meaning that they will only contain the updated files and folders. You can download and directly flash the OTA's !

Never mirror or share any of my OTA's without my permission ! I will quit providing OTA's and updates if I find out that any of my OTA's and updates are being mirrored/kanged or stolen without my permission. In fact I do not give any permission to any of the users to mirror any of my OTA's, if you have ported the ROM and shared with your users then just explain it to them that they can directly download and install the OTA's from Settings>Configurations>Updates
