Hello I try to play on my OnePlus Nord (AC2003) e/os. I followed the installation instructions.
Unlocking Bootloader - Done
Booting a custom recovery - Done (recovery-e-0.22-q-20220228166118-dev-avicii.img)
Sideload copy-partitions-20210323_1922.zip - **Signature verification failed, Install anyway? ** Error 21
If I skip the step, the same message comes when installing the “e-0.22-q-20220228166119-stable-avicii.zip”. **Signature verification failed, Install anyway? ** Error 21
Can anyone help me with my problem. Thank you in advance.

Pre-install instructions
at the end of that paragraph we see
Warning: The Recovery will present a screen that says Signature verification failed, this is expected, please click Continue.
It would be important not to skip that step … but to press cancel. (Signature verification does not happen with an /e/ ROM so you are being nudged to accept or acknowledge that.)
Hello Thank you very much for the quick help. I think the real problem is that I didn’t downgrade Oxygen11 to 10 … and therefore have problems with installation and later in use. I have now played Oxygen11 again. These days I will downgrade and start a new attempt to install eOS. For now, thank you very much.
hi, today the new installation started again. Downgrade from Oxygen11 to 10. The installation ran as described. After installation, I did a reboot. The name has now disappeared from the “Files” folder and some APPs can no longer be installed (PayPal). Deleting files is also no longer possible; the file manager then crashes. Something is wrong… and I have no idea what else I can do. Slowly I lose the desire…
Hello Since the installer is now offered for my Oneplus Nord (AC2003), I have made a new attempt to install it. Unfortunately, this one failed. As I have now discovered, the recovery is not accepted; at least the device keeps booting into the bootloader after flashing. By the way, this is also the case when flashing the TWRP version. I was amazed when I tested the Lineage recovery. Here you also have to flash dtbo and vbmeta. This works right away, even microG variant. Maybe someone has a tip for me. Even though Lineage is running great, I would like to switch to e/S with this device as well.
