1. Can I Unlock Bootloader on Oppo Reno 4 Z 5G?

Bootloader comes with a locked condition on each device and so the Oppo models need to be unlocked first to become able to get into the Android customization world.

It seems that you’re not being able to unlock the bootloader quite easily on your Oppo Reno 4 Z 5G because Oppo has blocked the bootloader unlocking process due to security measurements related to the device system and the user data.

An improper method or incompatible file can seriously damage your handset internally that means leads to bootloop or bricked status. However, if you’re using the Chinese variant then you can unlock the bootloader with Oppo’s official Deep Test apk.


2. Is There Any Rooting Method on Oppo Reno 4 Z 5G?

Again the answer will be NO because without unlocking the bootloader on your Android device, you won’t be able to flash root or gain superuser access whatsoever.

3. Can I Install Custom ROM on Oppo Reno 4 Z 5G?

Unfortunately, as of now, you won’t be able to install any custom or modified firmware on your Oppo Reno 4 Z 5G because you are neither able to unlock the bootloader nor gain root access. In that scenario, it’s impossible to flash a Custom ROM on your Oppo Reno 4 Z 5G until custom firmware developers come up with a compatible build apart from a proper flashing method.

It’s highly recommended to keep checking this article periodically to be updated with this info as whenever there will be a custom firmware or bootloader unlocking or rooting method available, we’ll update here.
