I'm using the old version of this (a9lh, need to move to b9s) :
https://gbatemp.net/threads/tutorial-booting-gw-with-b9s-and-some-help.471417/
so no, if I try to boot to GW on 11.4 I just get a black screen
so YWW will get me to 11.2 ? thanks
what do you mean ? of course I need to be in GWsysnand to update to legit 11.2 lol then install b9s.
as I said before, I end up on a black screen on a9lh/b9s 11.3 or 11.4 (ie, it can't even boot GW mode). (don't worry I understood loong ago that If I update on a a9lh system with GW mode on, I will overwrite the a9lh install and probably brick, but this is not at all what I'm trying to do here
)
thanks a lot for pointing me out in the right direction
