CSources2 cydia tweak is a toggle Sources Manager.
Add as many sources as you want.
Disable/Enable or delete them.
Check if Source is active.
I have added a couple backup methods. The main backup will allow iOS updates if you sync’d with iTunes or iCloud. If you change iOS or update/upgrade your device. Reinstall CSources2, and click restore. You can also email yourself or friends a copy of your list after backing up. Just select @ in the info page, select Contact, and change the send to address.
Transition from CSources to CSources2:
If CSources is installed, Backup before installing CSources2, this will allow transition.
If CSources is un-installed, but you previously made a backup, & you wish to transition.
Install CSources2. Before running CSources2 for the first time. Use iFile etc, Rename csources.list.backup to csources.list located in /private/etc/apt/sources.list.d.
Transition, will convert the old csources.list. Unknown data will be added to the notes section of (SomeRepo).
