Wiped EMMC, forgot do write new image, won't recognize EMMC

[zeno]

Hello everyone,

I wanted to install another distro to my Pinebook and wiped the EMMC, created a new partition and wrote the rootfs on it. After that I took a short break and when I came back, rebooted, totally forgetting, that I did not write the new uboot files.
When I tried to boot, it did not turn on, not even the LED. So I disabled the EMMC module with the hardware switch and booted to a manjaro image on the SD-card. I tried to enable it again after I booted to the SD-card and tried the commands on the wiki to detect the change (https://wiki.pine64.org/index.php/Pinebo...nformation).

Instead of working it gave me an error: "bash: echo: write error: No such device"

How can I get my Pinebook Pro to recognize my EMMC module again?

Thank you in advance.

EDIT:
Got it to recognize the the EMMC module, by enabling the hardware switch right after powering it on. Tho I can't mount or format it. It just loads and loads and nothing happens.
