I have a Samsung Galaxy Grand Prime (SM-G530T1) and I would like to install a version of LineageOS onto it. This is the first time I have ever attempted something like this. I did manage to install TWRP v. 3.1.1 onto my recovery partition. It is able to "boot" into this, but when I go to install the LineageOS .zip file, TWRP says:
Updating partition details...
...done

Updater process ended with ERROR: 7
Error installing zip file '/external_sd/rr-oreo_j30_20180804_NIGHTLY-gprimelte.zip'

I have tried Googling everything, and everything I see says to install a newer version of TWRP, but there is none released (that I can find). What should I do?
