I think the version you speak of is the one that bricked it in the first place!
I have just tried to apply it from ip camera tool and it gets progress bar to about 80% then freezes. Then a warning pops up but there is not message in the box just an OK button.
It has rediscovered the camera so its not bricked but its still showing 0.37.2.47
You are in a real pickle of a situation that most likely can't be resolved without the use of a serial TTY adapter.
The issue is this:
Due to you installing the incorrect firmware for the camera and coincidentally that firmware versions number being higher ("System firmware last two digits") than any versions for the correct firmware for your camera. That incorrect firmware won't let you simply downgrade to a lower firmware version.
This was done to protect camera owners. Because prior to the .59 system firmware versions. Many security vulnerabilities were found and fixed in the .59 systems firmware versions.
So the only way out of this mess. Is to use special firmware recovery software. Which I have, but it requires the use of the methods which I show in this thread which I created as well. Using a serial adapter.
Note: It's never recommended by anyone I am aware of to try this or that firmware before asking many questions first. In places like here. In most cases where that's not done. Results are equal to yours.
Usually someone here just by getting camera label and/or other details about your camera can tell you if it's good or bad idea. On a case by case, camera by camera basis.
There are no other methods to resolve your situation other than using a 3.3V DC TTL Serial Adapter, connected to your camera to install the proper camera recovery firmware. Are you willing and capable to take on a procedure like this, as shown in this Forum thread. At your own risk?
Do you see a FR or a VNT followed by letters/numbers ("The Cameras Wireless MAC Address") on the cameras label, anywhere?
Because the recovery methods and firmware used to recover the camera, are reliant on it being FR or VNT based, as far as wireless daughterboards are concerned.
If you use the wrong recovery firmware and methods. Your camera can become a eternal paperweight.
