    Hi everyone!
    I bought my buds z a couple of weeks ago. They came with global firmware (328 version). Everything worked fine. Pop-up notifications, find my device, battery status in notifications and other features were available.

    After I updated them (352 version) I lost all these features. I recently found out this is the chinese firmware. I am not being able to go back to the global firmware version and technical support wasn't able to help.

    Did anyone else have this problem?

    I am having the same problem too after update to the latest Firmware, ever since then there are no further update. It's very very annoying especially when you are listening to your favorite music or in a meeting.

    Apparently another user from the community had this same problem and was able to solve it by contacting technical support. They sent him some files and the instructions to do the update by himself.
    These are the screenshots




    I contacted technical support but they are not willing to provide the files. I really don't get their way of dealing with customers.

    If I get the files I will share them.
    Only thing I have found out until now is that BES upgrade app might be some app from Bestechnic, the producer of BES2300 (the chip inside the buds).
