I have a lumix gx85, the previous firmware version I was using was v1.2 and it worked quite well until I upgraded it to version v1.3, when the camera was not clear it was easily blurry, even though I had Tried turning off the anti-shake feature, manual focus and using a tripod, but the photos taken are not as sharp as before uploading the firmware. Although the camera screen when I focus manually is quite clear, when I click to take a photo, the image is not sharp. a bit blurry again
I don't know if there is any way to downgrade the firmware version of the gx85, thank you
Ps: I tried copying the old firmware version to the SD card according to the instructions when updating version v1.3 but it seems the device does not allow me to downgrade the firmware this way.
 
Yeah the combination works surprisingly well, even wide open at f/2.5

Just to note, the majority of GWC1 11MM converters sold on eBay come without the essential 37mm and 46mm connections which make the GWC1 useless because the adapters are required for a complete unit.

I got mine from eBay at very good price and seller made very clear the GWC1 was complete.

See you have the 35-100 f4.5.6 also. When I went all PL, I sold my f2.8 zooms, but kept the little 35-100. Amazingly sharp lens.
 
I've got a sweet little kit of 14mm, 11mm GWC1, 12-32 and 35-100 for GM1 all in compact case.

My 35-100 also is amazingly sharp also, even wide open.

I also have a GX85. I upgraded the firmware from 1.1 to 1.2 to 1.3. No issues at all. I routinely use the GX85 handheld with Dual O.I.S. with all kinds of lenses with excellent results, and it is also the body I use at home on a tripod with the 12-60 f/3.5-5.6 kit lens for product shots. I use the Custom Settings so I know the camera is set up how I like for stills in a light tent with manual focus and aperture priority and bracketing. It is consistent. I don't even have it set to disable the O.I.S. as this has never caused a problem. I get very, very good results. No loss of sharpness. What I'm really saying is that it's quite likely that the issue you are encountering is not due to any firmware upgrade but merely coincidental, or seemingly so. My suggestion is to explore other possibilities. For example check the state of the sensor. Closely inspect the condition of the rear element of the lens you are using. It only takes a tiny, almost imperceptible to the eye, mask of dust or moisture spray or even a finger or thumbprint (we've all done it and not noticed) to really destroy resolution and sharpness or even introduce odd artefacts. The least likely cause of an unusual issue in a mass produced item with millions of users is a unique firmware problem with your particular camera.

With this problem, I checked the pictures I took before before updating the firmware. I think this problem must be a rare case of my device. The problem is when observing the image and focusing the image. The result on the camera screen is still clear, but after taking a photo and processing it, it becomes soft and the image details are unclear. I had to fix the above situation by removing the lens and reinserting the battery and the results were better. (hence I'm quite skeptical about updating the firmware on my GX85 having problems)
ps: I used the same lens with the same focal length and the environment was bright enough to test
 
It's highly unlikely you can downgrade the firmware. I've never heard of Panasonic offering that option. Have you tried a factory reset since upgrading? That's probably the closest you'll get to replicating the previous firmware performance.
