Okay I see that the slots are easily switchable from TWRP so that solves that. Do you know if I can adb sideload the ROM instead of flashing through TWRP? I prefer the sideload1) crDroid Home
2) bank apps & Google pay works
3) some devices like Pixel 2XL have two slots, to change active slot you have to use command fastboot --set-active=a or fastboot --set-active=b, ask google for more![]()
