Tất nhiên là rom stock, còn cái vụ unlock bootloader thì nó hướng dẩn phải làm. Nó hướng dẩn vầy ko biết có đúng ko? To flash a system image:Download the appropriate system image for your device below, then unzip it to a safe directory.Connect your device to your computer over USB.Start the device in fastboot mode with one of the following methods:Using the adb tool: With the device powered on, execute: adb reboot bootloaderUsing a key combo: Turn the device off, then turn it on and immediately hold down the relevant key combination for your device.If necessary, unlock the device's bootloader using one of the following methods:If you are updating a Nexus 5X or Nexus 6P device using the hammerhead or angler builds, update your fastboot tool to the latest available version (>=23.0.1), and then run this command: fastboot flashing unlockIf you are updating an older device, run this command: fastboot oem unlockThe target device will show you a confirmation screen. (This erases all data on the target device.) See Unlocking the bootloader for more detailed instructions.Open a terminal and navigate to the unzipped system image directory.Execute the flash-all script. This script installs the necessary bootloader, baseband firmware(s), and operating system.Once the script finishes, your device reboots. You should now lock the bootloader for security:Start the device in fastboot mode again, as described above.Execute: fastboot flashing lock or, for older devices, run: fastboot oem lockLocking bootloader will wipe the data on some devices. After locking the bootloader, if you want to flash the device again, you must run fastboot oem unlock again, which will wipe the data.
