Hello @isaac, why are you afraid that I might be unfriendly? Treating each other with respect is very important to me. I only become unfriendly if someone has done that before me.
GSI ROM are ingenious on the one hand, but very error-prone on the other. Especially when the source firmware (stock Android 8-Oreo) and the GSI are Android 10 ‘Q’.
On top of that, the A3 2017 ‘a3y17lte’ does not come with Treble Project compatibility from the factory and the device has to be treblezied afterwards with know-how & tricks. This brings some additional error sources into play.
Customized customROMS aren’t only easier to install, but usually also more stable in use. It would be nice if there was a consistently working /e/ OS ‘Pie’ or ‘Q’.
