Q2: Are there any risks after unlocking the bootloader?

Please be aware that realme cannot guarantee the full functionality, and will not be responsible, for any third-party unsigned custom ROM being flashed onto your device after the bootloader is unlocked. An unsigned third-party custom ROM may not have gone through the thorough tests that we run for each device and software version that we release.

A third-party custom ROM may not work properly on your device, and certain functions and services may cease to work. The performance and device data may also be affected, and may damage the device permanently. In the worst case, unlocking bootloader will cause physical injuries or material damage for ex. due to device overheating.

Q3: Will it affect future OTAs after unlocking?

Secure user data partition may also become inaccessible and you will not be able to get official software upgrades if you unlock the bootloader. Once re-locked the bootloader, users will receive official OTAs again.

Q4: Will it affect warranty?

Warranty will be fully applied to problems caused by realme 5 Pro unlocking or flashing a custom ROM.

Q5: How to flash back the official ROM after installing a custom ROM?

Users need to go to a service center to flash the device FREE of charge. We are developing a tool to flash stock ColorOS – will come in Q2 2019

Q6: When other devices can get bootloader unlock?

Realme 1 will get bootloader unlock in Feb. Other devices are being considered.
