[Disclaimer: This is for rooted phones with NO system files modified or deleted.]
My L70 is SIM unlocked, rooted and MLT disabled. Did a factory reset last night with no problems at all. SIM unlock, root and MLT setting stay.
Background: I was playing with the app files and folders. I updated the permissions but did not preserve the file ownerships. Everything worked fine till rebooting. I got the UID errors and my apps and home screens were messed up. I manually fixed all the UID errors but still decided to do a factory reset to make the system clean. I did not uninstall any stock apps since it would not free any user space.
