It is a bad idea. I know, I've done that. The C.60 indian bulid have a lot of bugs even if you're not crossflashed it. The safetynet is not fixable after the cross-flash, so Google Pay and some other apps just not working. [edit: I've menaged to fix it, with magiskhide propsconfig + universal safetynet fix magisk modules installed] I hope that the EU version full zip from C.62 is coming soon, and maybe it will fix these things, so I dont have to reset the device. But maybe even with that I will reset it.
