Most of the issues seem to be with Hong Kong variants but it's not clear whether just the S8+ or also the S8.
Most people outside China who wish for Snapdragon models (U.S. Verizon, Sprint customers) can easily order off eBay from Hong Kong. And they already have Google Play services. So those models are more desirable for U.S. users, if they need Snapdragon chipset.
But they will need assurance this process will work for Hong Kong variants.
So if someone has Hong Kong and they got it to work or not, please specify your model number and that it is Hong Kong or mainland China variant.
Just saying "it works" or it doesn't work" doesn't give enough information.
