Nope, I tired replacing the kernel and ramdisk in boot.img and it instantly reboots, I tried replacing the dtb file in vendor_boot, also instantly reboots

Zekiu_[m]: I've just read the SHIFTphone 8 wiki page and it says to erase init_boot, vendor_boot and dtbo. Maybe you can try that?

I think in that case you should use header version 2 like on the lenovo-p11-pro-plus page

SHIFTphone 8 also uses header version 2
