Can i install new android without unlocking bootloader

The eternal quest for a clean slate!

In most cases, installing a new Android version without unlocking the bootloader is not possible. Here's why:

  1. Bootloader lock: The bootloader is a secure mechanism that controls the boot process of your device. When you lock the bootloader, it prevents unauthorized modifications to the device's software. Unlocking the bootloader allows you to install custom ROMs, but it also voids your device's warranty.
  2. OTA updates: Android devices typically receive over-the-air (OTA) updates, which are delivered through the bootloader. If the bootloader is locked, the device won't receive these updates, and you won't be able to install a new Android version.
  3. Custom recovery: To install a new Android version, you usually need to install a custom recovery like TWRP (Team Win Recovery Project) or CWM (ClockworkMod). However, these recoveries require an unlocked bootloader to function.

That being said, there are a few exceptions and workarounds:

  1. Carrier-locked devices: Some carrier-locked devices might allow you to install a new Android version without unlocking the bootloader. This is because the carrier may have a custom ROM or update mechanism in place. However, this is not a general solution and may not work for all devices.
  2. Samsung devices: Samsung devices, such as the Galaxy series, have a feature called "OTA update without bootloader unlock." This allows you to receive OTA updates without unlocking the bootloader. However, this feature is only available on specific Samsung devices and may not work on all models.
  3. Google Pixel devices: Google Pixel devices, such as the Pixel 3 and later, have a feature called "OTA update without bootloader unlock" similar to Samsung devices. This allows you to receive OTA updates without unlocking the bootloader.

If you're looking to install a new Android version on your device, I recommend exploring the following options:

  1. Check for official updates: Check with your device manufacturer or carrier to see if an official update is available for your device.
  2. Root and install a custom ROM: If you're comfortable with rooting your device, you can install a custom ROM like LineageOS or AOSP. This will give you more control over your device's software, but it may void your warranty.
  3. Use a custom recovery: If you're not comfortable with rooting, you can try installing a custom recovery like TWRP or CWM. This will allow you to install a custom ROM or update your device's software.

Remember to always follow proper procedures and take necessary precautions when modifying your device's software.
