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!

@easton
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 ??

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?:cat_face_with_tears_of_joy:

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.
