On the Internet there is a video link to video how to flash a similar phone using flashtool. But I do not have the firmware itself. Help, give a link to the firmware. Perhaps someone used this method for this device.
Also, there is a way to upgrade using UpgradeDownload. And I even found the firmware. But something doesn’t work out for me. Since it was precisely FF246 that no one was also flashing with this program, perhaps this method has no right to life. If anyone has experience, please unsubscribe. Maybe I'm doing something wrong.
