The 4.01 version is a non-official, non-public one, so it's a qustion how your phone can have installed it. Unfotunately you can update that version only manually. Both the manual OTA update and the flash tool ROM provided here should work but I recommend to flash with SP Flash Tool.
Checked and it still works properly. Maybe your country has issues to access mediafire servers. Try to use a download manager like Free Download Manager.
Apperently Priestfield is not the only person with Rom version 4.01
Look at the screenshot..... my phone is shipped 3 weeks ago by gearbest and I'm also running 4.01
This android 6 rom also the alarm clock failed two times.
The rom is running great but is an update to android 7 better or stay tuned for perfection?
With Android 6.0 (UMIDIGI Z Pro.V3.01_20170408) I had occasional problems with the alarm clock.
He did react at the right time, but was silent.
With Android 7.1.1 (V7.01_20170605 & V7.01_20170710) I had no problems so far.
Until now, everything is going well.
As soon as I find any bugs, I'll let you know.
Problems I encountered:
- battery consumption;
- Bluetooth turns itself off, and never stays on after a reboot;
- The hotspot does not switch itself off when there are no connections.
