[Huawei Watch 2] mcdull:
Some of you may experience "bluetooth" not able to start after upgrading to oero (8.0) like me. It was because, your device was bricked and recovered. Bricking and restore erase your BT MAC address and Oero enforced address checking of bluetooth. And resulting errors. An wearos watch without bluetooth is essential useless, and you are not given choices to upgrade or not.

If any one has any information to fix this address, please share with us. And you are more than welcome to share your efs partition with me, I need a bluetooth version efs partition.
