They will not work, and if by chance it does start you may end up with a corrupted backup. I know that it's easy to tell someone to buy an app but in this case I would suggest Titanium Backup. If you have a cloud drive (Microsoft, Google etc) then you can tell Titanium to backup to it and you will at least not lose your data. I chose this method as I am constantly testing roms, quirky software and settings that eventually make it that I have to restore. It's a suggestion and hope it helps!
Thanx! I will git it a try :good:
