You only said you encountered a problem with the operation, but did not specify the problem you encountered, so , I'm not sure what problem you're having.
If you convert version balance to GTR3pro,
the only problem you're likely to encounter is that the steps circle progress
is black. That's because ZeppOS 1.0 doesn't support alpha
(Transparent) function.
After you convert to GTR3pro, all you need to do is re-create the steps circle progress to be compatible with ZeppOS 1.0. However, for this part, you'll have to do more research by yourself.
And, you need to change the circle progress to image progress because Zeppos1's circle progress can't make a flat end, it can only make a curved end.
I've attached a sample GTR3pro version in this post.
Hope it's useful for you.
