Hello,
While updating from 24.10.5 to 25.12.0 on my OpenWrt One device I made a series of bad choices that ended up me having a device I can no longer connect to via ethernet, not via ssh or webgui.
I believe I must revert it back to how I got it out of the box and then work from there (and start reading into how it all works for once). The version that came with it was 24.10.0 iirc.
If anyone would help me explain what to do, or point me in the right direction, I would be thankful.
See
If the generic OpenWrt recovery options linked above do not work, you still have device specific options.
Actually, OpenWrt One should be unbrickable.
Doesn't it have its own recovery more behind a physical switch?
(Using both nor / nand flash)
Hope you haven’t used the NOR switch at any stage of your attempt. First step would be to try to boot into initramfs by power off and hold the front panel button depressed while you apply power. Release the button once all 3 leds have cycled.
You pointed me in the right direction, thank you.
Factory reset was in the end not needed.
I connected a usb-c cable from OpenWrt One to my PC and ran on said PC:
sudo picocom -b 115200 /dev/ttyACM0
Screen did not work, but picocom did.
This allowed me to gain access to my router again like it would with ssh (since ssh wasn't working.
OpenWrt 25.12.0 was still there (to my surprise), but not configured.
Connecting my router to my modem and running...
apk add kmod-usb-storage kmod-fs-vfat block-mount
...gave me all the packages I need to start the backup.
I formatted an usb with fat32 partition and uploaded my backup onto it.
Then I plugged it in into my router usb-port.
I ran:
mkdir -p /mnt/backup
mount -t vfat /dev/sda /mnt/backup
ls /mnt/backup
sysupgrade -r /mnt/backup/backup-OpenWrt-2026-03-05.tar.gz
reboot
This reverted everything to everything like it was before.
Now the only issue why I did all this was to fix both my ssid's showing up but not giving wifi connection.
I will read some more on this forum or elsewhere on how to fix this issue.
If I do not find it anywhere, I will make another different topic.
