@Naphtha normal flyme MX4’s can’t do this…
Before you can even flash you need to push an authentication file, it doesn’t care if its official or not.

Custom kernels for the MX4?

@anwar yeah same problem!

Volume down + volume up and ask for auth file?

@Naphtha Before to hold buttons we must click to Download after hold volume up + down connect device to PC. waiting 2-3 seconds and Error (5000).

try “format whole except bootloader”

We’ve already been through the whole preloader not working issue when the phone was first released, its fully locked down on normal MX4 which is why people are not able to unbrick their devices

Custom kernels for the MX4?

On top of providing the Download-Agent file, from what I can tell within the logs, you also need to provide an auth file that is

  1. an actual auth file
  2. valid.
    (FlashToolLib/sv5/common/interface/src/brom.cpp:726)
    12/25/15 21:26:30.553 BROM_DLL[34312][34316]: (5000) S_AUTH_HANDLE_IS_NOT_READY
    (FlashToolLib/sv5/common/interface/src/brom.cpp:729)
    12/25/15 21:26:30.553 BROM_DLL[34312][34316]: (5001) S_INVALID_AUTH_FILE

The software that we have access to doesn’t even have the possibility to load any sort of authentication file before downloading anything to the phone…

I just ship my phone to meizu HK repair center, because i did the same mistake.
I am not sure we can do anything with sp flash tool as the bootloader is locked.
He will always ask the Auth File
