Sooo, I decided to give it one last try and found the older firmware -
Onyx/Go7/Go7:11/2025-05-27_22-22_4.0-rel_05273_effe2ed7e/3390:user/release-keys (

I flashed your metadata and manmod, removed misc parition and tried autoupdate.
Unfortunately its stuck on 12% without any errors.
I wonder if I need to flash product, system etc for super partition using older firmware images as well. I suppose it must have different offsets, but which one?
Could you please suggest?
