Thank you @Manoj
dtbo.img is indeed the same I used: md5sum is 3bc7b2a307137a9148821236d04ae6c0. But vendor_boot.img is missing on resource you provided. And they removed 20221227 folder from LOS resource already 
I’ve backed up files I used on my Google Drive, so you can get vendor_boot.img there.
I think it’d be great to clarify in the documentation what are these files for and how one can get them directly to not depend on LOS resources and be more flexible with choice of /e/ version. It they are vendor specific proprietary images, it’d be good to add steps described here but with lemonadep specifics and explaination why does one need to replace existing partition images with specific ones (from specific version of vendor ROM?). If the files are modified somehow to match custom recovery, I guess the community needs to learn how to make those modifications and document it as well. I’d be happy to help, but I’m not even close to an Android developer
