I need help with this.
I installed /e/ with the Easy Installer, thus /e/ should be on both slots, is that correct? I did not lock the bootloader because I want to install TWRP and Magisk.
Now I installed TWRP, then Magisk, everything works fine. The phone is still in the slot which is active after installing /e/, in this case it is slot B. If I reboot the phone I get a splash screen saying that the bootloader is unlocked, after a pause the phone boots normally into system mode.
I think now I have to change the active slot to install TWRP and Magisk also to slot A. But if I change the active slot to A and reboot the phone I get a different splash screen as described above. It demands to lock the bootloader and eventually ends up in recovery mode. I cannot boot into /e/ in slot A.
What must I do to have /e/, TWRP and Magisk in both slots and to be able to boot into both slots?
Edit: Maybe it is not an issue with unlocked bootloader, TWRP and Magisk but an issue right after installing /e/ :
