Hi, I know about dsu-tool in Android 10 (and upper). I flowed instructions on developer.android.com, DSU says dynamic system is prepared, after reboot, the official firmware is loaded, instead of the dynamic one. I don’t know what I do wrong. Please, help me. P.S. Sorry for my bad English, I am from Russia
Hello art930,
As far as I know, Dynamic System Updates DSU is not introduced in Samsung devices.
This happened to me and I was really confused. In the end I realised it was something really stupid. I had to restart the device FROM THE NOTIFICATION, not just do a normal restart from the power menu. So tap the little down arrow on the right of the notification and you will see actions “Discard” and “Restart” - tap “Restart”. I can confirm that the DSU worked fine with my Samsung Galaxy Tab Active 3 (SM-T575).
