I bought one 路由狗 H68K aka LinkStar H68K on Taobao last year but I lost its firmware.
They provide download link but I couldn’t download it because it’s Baidu Wangpan 百度网盘.
A guy from VOZ forum helped me download it and now I’m seeding it on torrent. My computer are not online 24/24 so if you want to download it please contact.
