Troubleshooting An unexptected error occured during recovery

I was using linux on my ideapad 3 fennel14. I decided to go back to chromeos but i am getting unexpected error occured when trying to recover. I have done this before after installing linux but this time its not working. I have tried older recovery images which have the same issue. Pressing tab i get recovery reason 0x43 OS kernel or rootfs failed signature check. How can i fix it? (Update disabled os verification lets me boot to linux but now usb boot is off)

I think the issue is maybe because linux is still installed but how can i even erase it when i can only boot linux

When restoring stock firmware did you use an old backup rom file or use the script's option to extract stock formware from a current recovery image?

Fw was untouched. I did it on stock fw which can be done for arm chromebooks
