so im still on a9lh 11.2. everything still working so im happy with it. my only problem is if pokemon ultra sun and ultra moon will not run on my current firmware i will be forced to update to b9s. so is there any work around on this. and also if i updated to b9s can i stay on my current firmware 11.2 and dont update on latest firmware even if the guide says i have to update. may thanks.
