Hello! I recently bought a used TI-Nspire, and it came with OS 3.9. It is hardware revision A, so I believe it should be able to run lower OSes. So is there anyway I can downgrade? Thanks!

You can install Ndless and use nsNandMgr to remove the downgrade protection, then install OS 3.6. You can also use nBoot+ControlX or nLaunchy which can automatically install Ndless for you.
