reverting to stock firmwaew

[samersh72]

Hello,
pls any Help how to revert to stock firmware on my sonoff THR316 origin flashed with Tasmota?
i did not make a backup before flashing
Itead refused to provide me the stock firmware because the device is flashed with 3rd party firmware

thank you in advance
