I'm on LE2123 with OxygenOS 12 C.48 (LE2123_11_C.48) - I Tried everything to get root - nothing worked. I had either "unable to detect target image" or "no connection available".
Then i used another patched Image and everything worked fine. So here is what I did:

3. fastboot mode, "fastboot boot magisk_patched-24300_ZzKbU.img"

5. Power Off, fastboot mode, "fastboot boot magisk_patched-24300_ZzKbU.img"
6. Opened Magisk (still Version 24.3), direct install, reboot, everyting works fine
