alguien sabe como regresar de 5.0 a 4.4… me urge no le dura nada la bateria y no me deja mucho espacio en la memoria…
Por la memoria, no hay solucion con este ROM ni con 4.4 (por eso voy a probar lo que puedo hacer con "AOSP V3").
Pero, por la batteria hay que rootear tu dispositivo e instalar "DisableServe" (lo puedes encontrar en Google Play). En este app ir al pestaña de sistema y busca "Security Locker". Entra alli y deseleccionar "LockerService2". Tu batteria durara como un campeon despues de esto.
I flashed this ROM last month and everything seem to be fine.
Here's what I did after flashing:
1- I rooted with KingoRoot (I understand that means that I have let the Kingo group hack my phone).
2- I installed "DisableService" from google play and disabled Security locker (thank you all for pointing out it's drain on battery). I didn't feel comfortable with completly removing it.
3- I Installed Nokia's "Here" app for GPS navigation, and it seems to get a lock just as it slowly as it did before this update (but not slower).
My only gripe is that the partition sizing still sucks, so I'll be flashing AOSP V3 and the repartitioning script next. Pray for me!
