MX4 installation failed

[easton]

Ubports shows that the installation is successful, but after restarting, it will stay in the loading interface for a long time, always like this!

What happens when you press Volume Up or Down ?!

I always press it during the update process to see what is going on so maybe it works there too ??

• It stay in that loading interface
• Pass other button do not respond except the power key

Yes,I see it and try to do with SP Flash Tools, but i naver have auth file.I find some that named *.auth file ,so what you guess?

My MX4 is 2+32G and before on the device installed Flyme 6.3.0.2A.
Steps are as follows

Downgrade and unlock BootLoader

• Downgrade to 4.5.7A
• And downgrade to 4.2.8.2A
• root with kingoroot
• unlock BL with unlock_tools.apk

Install Recovery and Formatte

• I find a recovery tools box that can flash rec
• Then i try to do with SP flash tools ,but it can't use
• I used the adb tool to adjust the size of the 14 15 16 partition and renamed
• After all is completed, formatted into ext4 in rec

Ubports Installer

• It stay in that loading interface
• Pass other button do not respond except the power key
• Use Ubports to re-flash into a new system is still like this

When ubports pushes the system to the device, it is this interface, and the progress bar has never moved

@easton Well done, please mark as solved https://forums.ubports.com/topic/6311/how-to-ask-a-question-and-then-mark-it-as-solved If you use windows again try 15 sec adb from xda developers install system wide and remove any other adb tools first. ADB has a habit of getting lost on windows.
