Try firehouse loader from signed firmwareWhen flashing Meizu 16x (M1872) to remove the phone code, I get this error:

!!! WARNING !!!

- To avoid any toubles, please always use official firmware !!!

Reset Flyme Account Lock was released for old models, it will not work for new model.
- Authorization should only be used for normal flashing with official firmware that match to your model
- Special Tasks are bonus feature, if it fails you can not claim a refund
Any Special Tasks in MediaTek platform require write access and will not work for this model due to secure boot.
- Service cost for [Meizu] M1872:

You have used 1 available MEIZU_FL slot for this phone, you have 2 FREE slot left to try again in case this task fails.
You may retry the task for more times without further authorization as long as you don't unplug the USB cable.
I tried it several times, please return the spent 5 credits. Thanks.
