Hi,
Thanks for your answer.
The M11Pro did reboot after several tries.
But it seems it is not usable anymore.
1°) As I said, the oogle Play Store does not work and I had to install it with APK Pure ;
2°) Google Play Store fails tioo update Fiio Music ;
3°) Fiio Music installed from the Fiio Applications does not work properly with DLNA : playback stops after 3 seconds ; it works if I unsintall the update ;
4°) mConnect reports "File format not supported" as soon as I play something else than 16/44 files... From the same source, mConnect can play files flawlessly if installed on another device. Those files are played correctly when using UAPP and Bubble but UAPP can't really be used because it does not allow to sort files...
So either there is a huge problem in one of the latest upgrades ; either my device has a hardware error. In both cases, I can't really use it
