I just intalled a custom kitkat rom for locked and unlocked bootloader : http://forum.xda-developers.com/xper...-v4-1-t2618315
My bootloader is locked.
It works great but during each boot, I have a message that says : Update android, launch applications. It lasts 2 or 3 seconds but it's annoying.
I post here because I'm not a developer so I can't post on the rom post.
Sorry for my english, I'm french.
Thanks by advance !
