I failed to install latest eRecovery versions recovery-e-0.23-q-20220513185542-dev-davinci + recovery-e-1.3-q-20220825213388-dev-davinci.

The terminal entry does not show an error.
Reboot to Recovery does not enter eRecovery, but Fastboot-Mode. The system does not boot to Stock Android 10 after the installation, only the FASTBOOT mode still works.
Alternatively, unofficial TWRP Recovery version twrp-3.4.0-10-davinci-mauronofrio.img was now installed. There Reboot to Recovery takes place again into the TWRP menu. Immediately by adb sideload e-1.3-q-20220825213388-dev-davinci.zip was installed. The reboot into the system works, /e/OS-Q can be submitted normally.
Now I installed recovery-e-1.3-q-20220825213388-dev-davinci via TWRP “Install”. After reboot my Mi 9T screen stays black again. Neither eRecovery nor /e/OS start. My Mi 9T appears to be dead. Only the FASTBOOT mode still works.
/e/OS-Q eRecovery not only installs on my Mi 9T, but also blocks a system boot into stock Android or /eOS-Q. Only with Mauronofrio’s TWRP did I manage to install /e/OS-Q. The TWRP also works as it should.
