FP6+ and problem with install e/os - QUSB_BULK_CID

I bought new Fairphone 6+ and i decided to instali /e/os.
I tried to install /e/os using the official installer in a web browser on the e.foundation website. The installation went smoothly: I unlocked the bootloader, flashed the files, and finally saw the message “The installation is complete!”. But the phone didn’t reboot. The screen went black, and now when I connect it to my computer via a USB cable, it’s recognized as QUSB_BULK_CID:0463_SN:(serial number here).

I am sure that online installer downloaded file: IMG-e-4.2-a16-20260815662938-official-FP6.zip (Security patch: 2026-08-05).

What should I do in this situation

When you cant boot into recovery, fastboot or system, only FP can help you.

And just for the records: it seems to be better to not use the web installer to flash e/OS.

I can’t coot into recovery or fastboot. Screen is completely black and no reaction on pushing buttons:/
