Did you try to just start from step 4 again? You can also open a command window and start flash_fp4_factory.bat from there (after changing into the correct directory). In case of an error the window will then not close.

Next trial. And the final step 6 was successful. With the little help of OBS I was able to record the last lines before the window was closed: [image] But the FP4 is in a “boot loop”, it reboots and reboots. I have no chance. :frowning: :frowning:

I always have started the batch file within the command window and not by double-clicking. But it closes anyway. In the meantime I tried it again - see my updates. But I can’t boot into recovery mode; neither by the menu, nor by fastboot reboot recovery, only into the The FP4 boots always with th…
