I just installed this and it worked just fine.
I flashed the twrp from to op, rebooted in the twrp recover, then factory reset, used advance format to clear data, then used adb sideload to install the lineage image and open gapps nano. It took it about 5 minutes to boot the first time.

How much of a process is it to go from building version 16 to lineage 17 for this device? It would be really cool to get android 10 you know.
I am a newbie here as well, tried this thread and made some progress. The tab did boot into the OS the first time, asked me to setup and then I realized I was missing gapps. Now, the tab is stuck in reboot loop... I see the startup screen with the little blue ring moving from right to left and then the tab boots into recovery mode. Cant get past this
