ECUTek stock rom files?
 

I've done searches and old threads indicate stock rom files are downloaded automatically but those are old threads and I don't see any stock roms anywhere on my laptop. Where can I get ZA1JB01C rom files to flash back to stock?

Found them in an different thread. You need to go to Help then do an update and then at the bottom of the screen there is an option to download stock roms.
