I bought a set of AIO-5LITE on Dabao.com and asked the merchant to activate the international version and send it to Taiwan. At first, carlink was usable. On the morning of October 29, it was still working normally. In the afternoon, when I turned on AIO-5LITE, it showed that it is not supported area 
My version number is 2.9.2 (24129/20021)
I tried to use the firmware from the forum to refresh the version to 2.9.8 (0914_170026) and 3.0.5 (beta version), but carlink cannot be used.
Is there any firmware that can be used in Taiwan?
