Lineage or ipod?

I’m starting the withdrawal from google as best I can. Already switched my number to a burner and am currently using a Galaxy S5 for signal and any other “smart” things wifi only. I’d like to load lineage, but when I did the CID check, I think mine was 11, which seemed to mean my bootloader was not unlockable. I’ve also got an S3 I could use, but I can’t seem to get TWRP to replace the recovery mode. And when I try to flash the Lineage image with standard one it fails on checksum or signature or something like that. Both are Verizon if that makes a difference. The page for the s3 seems to have gone offline in the last week or so, and it looks like it may not be supported anymore.

Which way to go? Or should I just pick up an Ipod touch and be done with it. Dont really care too much if I have gps… got old school garmin and tom tom if i need it.
