This is to inform you that I have successfully installed android pie on my GT-N7000 after following your clear instructions. Yes i installed lanchon partition tool from /tmp and then android rom. I am going to install pico gapps after using the phone for a few cycles. As the battery drained very fast after this installation i am charging it again. Thank you again for allowing the fruits of your labour.
Glad that it works for you.
For GAPPS, the setup wizard will stuck at checking for updates section for a very long time. This is to be expected, leave it as it is. Until it says that it might take longer than usual, then a moment later it should pass.
