0. Install testkit firmware/enable debug settings
1. Open Settings App
2. Scroll down to the ★Debug Settings
3. Click on System
4. On "Region Setting" change it from China to North America
5. Sign into any psn account! it should work now
After the account is linked you can change back to normal firmware if you want. the region check is only when linking accounts
anyone with a real china console wanna try this ? haha
