Thanks for all your hard work!
I completed the process and successfully installed the missing BP function!
The long route is quite easy and i had only to put the watch in airplane mode with only wifi connected because on my LTE watch with eSIM installed there was no way to connect the device...
The version. from Xioami Store is only in chinese and i see only screen asking for my phone number. You can select English after that step or you need an English version app? In this case you have a link?
I have a PACEfied Chinese Amazfit and an Amazfit US version with original firmware,
You can also load custom watchfaces on Amazfit US version with stock firmware.
You just need to create into the internal storage a folder named (exactly!) WatchFace copying then all yours watchfaces inside it...
If i can suggest something for future version...
I always use the two levels of pie and, as the internal pie is smaller; would be great to be able to select different icons sizes: smaller for internal pie and bigger for external!
