FHP20Tool allows you to rebrand these models to other regional brandings.
FHP20SingleToDual allows you to rebrand a single-sim phone to a dual-sim one.
Warning: You can use this tool to rebrand CLT-L04 or EML-L04 models, but due to hardware differences it is not possible to enable dual sim on those models. Single sim to dual sim is only for CLT-L09 or EML-L09.
Warning: You will need to unlock your bootloader for this tool to work.
Warning: If you are rebranding Chinese to non-Chinese (AL00 to L29 for example) and your phone has a recent firmware installed, you should downgrade to a lower version before trying this. There is danger with recent firmware versions, going from Chinese to international. Contact us for details. If you proceed and render your phone inoperable without regarding this, it is your responsibility and we cannot refund your payment. Be careful!
Warning: Make sure we have available firmware for the model you are rebranding to before using.
