 So, are you using a Hello Watch 3 and you trusted that the manufacturers will continue to provide updates and make it stable? But you were disappointed like the rest of the Hello Watch 3 owners! But in this post, I am going to bring your Hello Watch 3 back to life! In this process, we will be updating the Hello Watch 3 to the latest watchOS 10 update which is v4. Normally all Hello Watch 3's are running v1.00.56 right now, and in this video we will update it to v4.00.11 which was released earlier in the December.
