You might study the published stable versions for this device /e/OS stable herolte download.
I am not aware that OTA Android version upgrade to Android 12 (S) was released. @Manoj please could you help, I do not see this OTA Upgrade in the development-updates.
Edit My mistake an OTA Android version upgrade to Android 12 (S) has been released quite recently. So connection to the testing channel is unlikely to be relevant.
@hougo had you connected with the testing channel?
If you are in difficulties I think you should start a new thread (but perhaps you are ok) but in this thread it is hard to follow.
So that would be associated with Android 10 (Q) e-1.17.1-q-20240208379201-stable-herolte.zip … then previous line
… so is this an Android version jump from Android 10 (Q) to Android 12 (S)?
On the face of it this thread looks similar Need help - S7 freezes all the time… in the jump from 1.17-q to 2.2-s (if I read the situations correctly).
