[Galaxy Tab S2 Q&A, Help & Troubleshooting] zed011:
I am using lineage 17 to be more specific, using lineage-17.1-20210718-UNOFFICIAL-gts28wifi.zip

Tried again on another computer, I managed to push but everytime after reboot, wifi refuses to turn on. I did reflash of lineage to restore wifi and tried again same thing. This is my terminal. How many files should be there before and after push?
