better to ask here:Okay, then it will be rather difficult for me to start PE13 installation with Stock Android 10 being installed.
So, your second suggestion now is valid, i.e., trying the same that I did earlier and described above but with the vndklite variant?!

(@PedroJvan tested PE 13 GSI on Huawei hi3660 running EMUI 9)
So I'm wrong, no stock A10 is required, sorry, I'm old and tired man
