Firmware update to 21.1.0.41

[Alessandro]

Hi, i have a little problem, maybe someone can help.

I have bought a yyt-f5003 (https://www.amazon.it/ueberwachungskamera-rilevamento-movimento-telecamera-yyt-f5003/dp/B07D8LMZ8T) and installed on my iphone the Yoosee App.

The app says that there is a new firmware version, 21.1.0.41. The process will start and when arrived to 99% a voice in the cam say something like "upgrading, dont power off or disconnect"; after that, the app on iphone say:

Update failed,errorCode:-5764607523034233982

Every time. Someone has any idea about?

Thank you!

I've got the same problem, only trying to update to from 21.0.0.40 to 21.1.0.91.
There is an option for "backend upgrade" and I suppose it indicates that you can download the firmware and installe via the microSD card. But from where can I download the latest firmware? Anyone?

Choosing a different time to upgrade its firmware. Upgrading failure occurs due to slow download speed.

Thank you for your replies. I've tried downloading firmware almost 100 times, in every hour of the day, without success. Maybe there is a problem on the application, or over the CAM. Waiting for an admin reply for more information. Also i'd like to know where to download the firmware file for trying manual upload with the IPC Debug tool!.

A little specification: the download of the firmware go over 98%,99% or 100% (difference based or various try). The cam start the update with the voice, but after that, applicatoin give the error.
