I already had problem where my phone was turning on for a while, showing 'apps are optimizing' and 'no storage left'. I had fixed it previously using recovery mode and wiped cache partition. Everything worked perfectly straight away.
However this time I tried already wiping cache partition in the same way about 10 times already and I also tried to manually delete all content of /cache using adb and su, with no success.
Is there anything I could do to fix it?
If this can help, my phone is Nexus 4, running rooted 5.1.1 lollipop.
