Only Raspbian Stretch is compatible with the 3B+ model. If you have the older Wheezy or Jessie version then you need to start over with the latest Stretch version (Wheezy and Jessie are no longer supported).
If you have an early version of Raspbian Stretch (prior to March 2018), then all you need to do is update it with the following command.
Code: Select all
sudo apt update && sudo apt full-upgrade -y
The update can be done in your old Pi1 model (any model of Pi that boots the card can be used to update).
Note: If it's the Pi 3B (not +) then Jessie will work with an update (but Jessie is still end of life and should be replaced with Stretch).
My mind is like a browser. 27 tabs are open, 9 aren't responding,
lots of pop-ups...and where is that annoying music coming from?
