FLASHING

•Ito ay paraan upang ma-laod o mainstall ang isang OS, Custom ROM, modified application, Kernel at ibang system requirements through Recovery (CWM, TWRP) and Flashing tools (eh. ODIN, HEIMDALL, FLASHTOOL).

BOOTLOADER

Ito yung code na nagra-run bago magstart ang OS. Parang sa PC meron din bootloader or startup boot. May mga manufacturer na locked ang bootloader tulad sa HTC merong Hboot.

NOTE:

Pagkakaiba ng unlocking bootloader sa rooting - Ang rooting ay isang proseso upang magbigay ng permiso para i-modify ang system katulad nito ang permiso ng admin sa pc. Ang pag unlock ng bootloader ay pagpasok sa system ng phone, (hindi mismo ang OS). Bali tinatanggal lang natin ang harang na nilagay ng manufacturer para magalaw ang phone sa anumang kaparaanan. Hindi ka makakapag root o makakapag-flash kung hindi pa unlock ang bootloader. Pero ito'y depende kung ang root ay nangagailangan ng pag modify sa kernel, pero kung hindi ay maaari pa ring makapagroot tulad sa Xperia. Ang Samsung ang isa sa mga tanging Android phone na hindi lock ang bootloader.
