Hi Onkel,

Ah OK that's what I thought with this firmware (modded firmware by cor35vet) it should work.
So you upgraded to the last one in Chinese and you can not go back?

Hi Porto,

Yes, i Update one to chinese, this cam can Not updated now to other Firmware.

Humm, interesting to know it.
May be this firmware incorporates a security certificate that prevents you from coming back.
Maybe cor35vet can do something for you.
