OK, I solved the problem with uv and the broken model. Maybe someone will help. Or I'm the only one who's not paying attention.
Using chromecacheview, copy the files to another folder "file.osgjs.gz", "model_file.bin.gz" and "model_file_wireframe.bin.gz" They will be in txt format. Opening blender click on the window with some code and the keyboard shortcut alt+p (not always pressed the first time) Import the file and save it as blend. Open already in a new blender and export to fbx if needed. Textures can be found in the same chromecacheview or in network. You just need to open them in a new tab and save them.

Thank you so much for that way to rip models. It saved my life
