Is it possible to roll back a .kicad_pcb file?

Hi, in a bit of a pickle and wondering if anyone can help?

Basically, I have a .kicad_pcb file that I made the mistake of opening in 8.0.9 and saving, as I result I updated it and now can’t open it in 7.0.11 anymore.

Know that would normally not be a huge deal, but in my case, I’m using other software that really doesn’t like V8.

Anything I can do to roll it back?

I don’t know if this will work but, you can try it…

Open the PCB file in a Text-Editor and change the Version to the same text as for a Good v7 file shows. It’s listed at the top line of the file.

Can also (using v8) export Gerber’s and open them in v7. When in the v7 Gerber-Viewer, File>Export_to_PCB_Editor; it becomes a Project (in v7)

Exporting Gerbers is an option, but it’s far from perfect. You can get all the copper and the PCB outline, but Footprints are not even defined in the Gerber files, pads will just be copper features.

The best option is to look into the kicad_backup directory. It likely has a bunch of zipped backups from previous versions.

And for the rest. Learn to make your own backups. Shit happens, so prepare yourself.

Did you check the backup folder? I usually turn off automatic backups but if you do not, you might have an older file in that zip?
