Hi
Is there any offical safe method or guide to downgrade the iPhone 6s Plus to OS10.3?
I am using cross platform tools (NOT xCode) to develop Apple apps. I try to debug the apps through Mac Mini and iPhone 6s Plus. The development enviroment has OS10.3 stable version supported.
I want to downgrade to OS10.3 to debug. Is there any 'Safe & Detail' steps or offical guide to follow?
Thank you for your assistance.
