Hello.
I am trying to install LineageOS for Microg - lineage-19.1-20220611-microG-lemonadep.zip
I followed the instructions from LineageOS (main) https://wiki.lineageos.org/devices/lemonadep/install
but, of course, using the LineageOS for Microg recovery lineage-19.1-20220607-microG-lemonadep-recovery.img and zip.

I installed the dtbo.img and vendor_boot.img from the latest LineageOS repo - https://mirror.math.princeton.edu/pub/lineageos/full/lemonadep/20220628/

All good - until I flash the zip in recovery.
The I get:
E: Current SPL: 2022-06-05 Target SPL: 2022-05-05 this is considered a downgrade
E: Denying OTA because it's a SPL downgrade

How can I remedy the SPL error and flash successfully LineageOS for Microg - lineage-19.1-20220611-microG-lemonadep.zip?

There's your issue, you are using a different vendor_boot and dtbo version. Notice how you downloaded the 20220628 files instead of the 20220611 ones, and also your recovery version is not matching either. Unfortunately, it seems you can't find files that exactly match your build, but I will do my best to point you in the right direction.

Try using https://mirror.math.princeton.edu/pub/lineageos/full/lemonadep/20220607/ first. If that doesn't work, try https://mirror.math.princeton.edu/pub/lineageos/full/lemonadep/20220614/. Those builds are closer in date that the latest one, so this might remedy your issue.

Thanks for your reply! Yes, I suspected that! I tried 20220503 - as it was the earliest! It then failed to boot to recovery, so I restored the latest - but also had to flash boot.img.
Why do you recommend 0607? Hmm, are the earlier ones for LOS18 perhaps??
I will try in the morning!
Thanks!

I recommend 0607 only because the build date is closer to the LOS+microG version you are trying to flash.

I also double checked and the two builds I mentioned are indeed the earliest versions of LOS 19.1 for the OnePlus 9 Pro.

Having the same issue here, and the link :https://mirror.math.princeton.edu/pub/lineageos/full/lemonadep/20220607/ is no longer available, tried looking for it in the WayBackMachine but they only stored the page not the file itself, guess because of its size, can't find it anywhere else, can anyone who downloaded it re-upload it again to solve the same issue @anarchotaoist ?

Waited for the MicroG team to update their builds, but they still did not.

You should use dtbo, vendor_boot and boot images latest from may
or you can dump the rom's payload.bin and use those already included in the rom

you can try crDrod or stagOs (they both suport sign-spoofing) with spare microG
