Inside the Zip are two Directorys: META_INF and system.
Inside META_INF there are three files: CERT.RSA, CERT.SF, MANIFEST.MF, plus a Directory: COM and inside this is another Dir. Google, and inside that another Dir. Android, and inside that two files Update-binary, and Updater-script.
inside the System Dir. another folder: App and inside that SystenUI.apk
I’m not likely to let this alien folder sit on my drive, and if necessary I will copy all the other files on that drive and then format the drive itself before coping the good files back again, but this is a bit formidable I’m sure there must be a way to un-protect this file and delete it. I’ll keep trying I don’t easily let things beat me if I can help it.
