Yes, I have performed the procedure often, for years, I have not made any errors.
I tried both the recovery menu ("flash recovery image") and the startup method ("e2up").
In both cases by copying the "dual" folder to the root of the USB stick, as always.
After the reboot, however, nothing changes:
- I'm not asked which slot to flash the atv7.3 recovery image into.
- the 4 images remain in their slots.
This is after updating the Android fw with the special1.04 and 1.07 versions.
Now I've gone back to fw 5.0 hoping to solve the problem, but unfortunately I can't anymore, the slots are not reset and the ATV 7.3 recovery image is not processed
Thank you for your interest
