The device is an iPhone 4, iOS 7.1 beta 1, jailbroken with cydia updated. When I tried to add a source, I closed cydia, and it corrupted the sources file. It says there is a malformation in line 5. Therefore I want to open this file from the computer, since I did not install iFile, and I also do not have SSH installed on it. How can I do this? I'm on a mac. I tried with iFunbx, but it won't show the root folders, only the media one. Is there something else I can do to access the root ones with my mac? Thank you!
