What I noticed within these few days is that XiaoMi release a latest IP camera firmware 18.104.22.168B_201603181307 to anyone who connect to XiaoMi Server to view their IP camera.
I had a close friend that bought the same camera at China, he updated to latest firmware. It works OK at the first place because he was connecting the IP camera at China (Because currently he is working at ShenZhen). But nightmare starts when he went back to Malaysia for short vacation, and the IP camera no longer working.
A uncommon voice message prompt and said “you can only use this camera within China”.
I took some risk too and update my XiaoMi IP camera to that problematic version, and hit the wall for the whole night. I was trying to rollback the firmware to older version, but it never work.
I am quite confident that I am not the only person that face this issue, there are a couple of MIUI forumer hit with the same issue too. But some of them successfully rollback the firmware version.
