What is firmware? Firmware is a specific class of Linux computer software
Oppo Firmware is a special class of computer software that has a role to control the hardware of the Oppo smartphone, so if one part of the firmware has a problem, it will greatly affect your performance Oppo and even your cellphone may experience Softbrick “The application always stops suddenly, Can’t boot to the home screen, recovery, just stuck on logo or Blinking red light” or Hardbrick “EMMC is weak, Problematic hardware”.
What is Stock rom? This is the official or original factory-installed firmware which hasn’t been modified at all by third party users. But not infrequently there are developers outside the official company who dare to modify it by making a custom rom in order to be modify the UI “user interface”, Alternative to Bypass / unlock FRP or a more user experience such as LineagoOS, MokeeOS, CyanogenMOD, AOSP, Flyme OS, Havoc OS, Resurrection RemiX, MIUI rom, Android ONE rom, or just Porting rom “EUI, GIS android open Source, EUI, TouchWIZ, Color OS, One UI, Android ONE” from other devices with same chipset. Keep in mind that if you want to flash a custom rom, then the first thing you need to do is unlocking bootloader, Rooting, Installing TWRP recovery. Until there you can flash a custom rom, Xposed Installer and other.
What is Flash ROM? Flash rom is a universal flash programming utility that is used to detect, verify, delete, read or write firmware partition. There are two types, namely R850 OTA Update or R850 ROW firmware
- OTA Updates (Recovery, SDcard, USB upgrade) usually in the .zip archive from official update to fix some problem , all of upgrading such us from Android 9.0 Pie to Android 10 Q OS version, there are the following files
- stock /System/… or system.dat
