Had some slow internet this morning and I decided to reboot. Now I am boot looping. I am on 5.0 and not installed any addons or anything crazy. Not even any apps in the past few days. I have cleared the caches and even tried to install over top of the slot. I have let the boot animation sit for 20 minutes and still nothing. Any ideas?
I think this was caused by a data writeback tweak I have in place, it uses the tunefs binary to turn off data writeback off on /system, /data and /cache. Sometimes on an unexpected shutdown some system files can get damaged, did you reboot via the Power Menu or a widget/app?
