I was trying to update my Volumio which was installed by Allo when I got this player, but after I clicked “Update Now”, it popped up " System Software Integrity check failed, manually edited files were detected. System Software Update is not possible under these circumstances. Please execute a Factory Reset or Delete User Data, then retry."
In fact, I never edited files. I therefore executed a Factory Reset, but still didn’t work. It still popped up the same message. What should I do for the next step?
Volumio Version: 2.853
Hardware: Allo Boss player
DAC: Allo Boss DAC
