Hello,
why would you like to medkit your Turris Omnia?

The router itself should update it to the latest version, but you’re looking for answers, which are in documentation.

my router can’t connect to internet because of non-standard L2TP (dhcp + l2tp) of my ISP

4

also curios what each of those represet
@Pepe got a minute to explain?

medkit/omnia-medkit-latest.tar.gz is the latest medkit built for that release - something to flash via USB
openwrt-mvebu-Turris-Omnia-rootfs.tar.gz is a leftover of some build that wasn’t deleted by accident
nor_fw contains u-boot and rescue system that are in NOR

some “accident”
thx anyways :slight_smile:

so I accidentally wrote to the /dev/mtd0 and /dev/mtd1 partitions. How can I restore the rescue flash layer? I was able to get uboot back by kwboot the uboot-turris-omnia-spl.kwb over serial and the tftp the kernel and used mtd to write the kwb file and got uboot back, but now I can’t use the medkit to start from scratch because I believe it relies on the rescue partition, do I need to flash uboot-turris-omnia-uart-spl.kwb to that partition?

This is where I am at with the medkit file

Ok Looks like I had to flash omnia-initramfs-zimage to the mtd1 and medkit worked just fine then. Thanks for the insights!
