Well, unfortunately, the model is not enough, that fresh is still not popular and not from the top shelf ...
But you can see some firmware already found.
Fortunately, I managed to make it usable without loading anything, even without restoring the factory settings.
I just tried to run it in safe mode. When it was turned on, with the message "COTA Data ..." displayed, I kept the power button pressed, after the window appeared with the selection of switching off the phones, or restarting it, I held the "restart" option for a while until the message about starting in emergency mode, which of course I confirmed.
I do not remember whether the phone immediately started up to the system, or if I had to quickly enter the PIN code to run, or repeat the procedure with emergency mode again ... but eventually the normal system turned on without this annoying error. I was able to connect to WiFi and update the software (relevant information showed up), the phone started again and for now it works as nature wanted.
