I am currently running Calyxos on a pixel 6a. because there are no more updates for that (currently) I want to install e /os/.
Only I can’t find what the Security Patch Level is of e/os/ for my device so that I can judge if I don’t Brickk my device.
roll it back to stock Pixel 6a ROM then go to eOS problem solved:
Please first read Factory Images for Nexus and Pixel Devices | Google Play services | Google for Developers
Warning: The May 2025 update for Pixel 6 (6, 6 Pro, 6a) and Pixel 8 (8, 8 Pro, 8a) devices contains a bootloader update that increments the anti-roll back version for the bootloader. This prevents the device from rolling back to previous vulnerable versions of the bootloader. After flashing the May 2025 update on these devices you won’t be able to flash and boot older Android 15 builds.
This warning keeps changing … now there is further information on this link.
