[QUOTE=NekoMichi;43508]Your device storage memory is separated into 2 partitions, the partition where system apps are installed is separate to where your music and App Store apps are kept. RetroArch (and any other app installed through Cydia) are installed to the system app partition, which has a far smaller size.
To fix this, you’ll need to install “Stashing for iOS 9.2 - 9.3.3” from CoolStar’s repo at coolstar.org/publicrepo[/QUOTE]
tnx for helping me.
yeah your right. the other partition is full because i accidentally copied a iso file sized 1.5 to that partition.
but i already deleted it and i installed the tweak but still the other partition is full.
i really dont know whats wrong and i really don’t want to restore my phone.
and i already tried with icleaner to free some spce but no luck on system partition.
UPDATE:finally managed to install it.
the problem was i installed the stash tweak from HYI source.
but i deleted it and installed it from the source you gave me.
all good now.
tnx for your help. <3
