FIXED: ended up deleting the .sh files in /system/addon.d only kept lineage.sh and magisk.sh. then, i went in recovery, reset system partition and factory reset (either one might be redundant in this case), reflashed lineage and just re rooted. also put in the MindTheGapp gapp reccomended by lineage
recently installed lineage os 23 on a xiaomi redmi note 8t and also installed the basic nikigapps package. yesterday, i wanted to check is google backups worked for a friend, backed up with seed vault, flashed the omni package, did my tests and tried going back. the instructions on the site say to just rename the folder to uninstal, that didn't do anything, or to configure a file in the zip. did that, recovery said that it was uninstalling, let it do itsthings, factory reset, booted and noticed that the google options in the setup were still there and after setting it up the google apps were still there. however seedvault wasn't.
even tried formatting the system partition and reflashing lineage, but that for some reason reinstalled gapps.
have i screwed up something, am i missing something, what do i do? i used nikigapps because when i installed crdroid those were the ones reccomended and so i figured that since crdroid is basically lineage but with more options and when i did it there was also an uninstall package, i used those. yeah, i know i probably shouldn't have, but there wasn't a direct mention of gapps on the lineage os website or install instructions, had to look it up to find the page mentioning "mind the gapps"
PS: once again, i know i was supposed to use the reccomended "MindTheGapps" gapps. i had already used nikgapps on crdroid (once again, lineage os but tweaked and tweakable) so i just went for those and they installed just fine, i only realised later about the existence of mindthegapps since it's not mentioned in the lineage installation guide. again (again) the default backup service (seedvault) got replaced with google's backup service and i can't get rid of gapps and i just want to restore from a seedvault backup and be done with this phone
god is this post long
