I have an Apple Watch Series 3 on version 4.3.2 and an iPhone on 12.1.2. My Strava app will not run on the clock crash as soon as it is open. I have read that installing the latest clock OS 5.2 corrects the problem, but to update the clock, I must be at least iOS 12.2. I want to avoid this because my phone is jailbroken and if I update, I will lose the jailbreak.
I am looking for an alternative way to update the clock OS. I have been told that whatever is needed to connect the clock to the iPhone, both must be on the latest firmware (5.2 and 12.3.1). Is it true? I was thinking of pairing my watch with someone else's iPhone, updating the clock, and connecting it back to my iPhone. Wouldn't this work?
