Also I have been trying to use the most recent boot2 file however most things I find say to use 1.4?Yup. 1.4.1571 works just fine. Newer 3.x versions do not bring any user-level feature, but bring a massive anti-feature: enforcing the silly anti-downgrade protection, while it can be easily defeated in boot2 1.4.1571 :)
Where can I find 1.4?It's embedded in OS 1.7.2741, for instance, and you can retrieve it with pretty much any program able to decompress ZIP files: Nspire OS updates are just ZIP files with an extra header ignored by most tools :)
Right I get all that. The issue is I acted as your standard consumer and installed the update from TI without thinking about it and now my calculator is bricked. I am trying to recover it. It is to late to run anything through TNOC.QuoteAlso I have been trying to use the most recent boot2 file however most things I find say to use 1.4?Yup. 1.4.1571 works just fine.

Users aiming at keeping control of their calculators (rather than letting TI do it, which they have no business of doing) should never transfer unmodified 3.x OS upgrades; TNOC should be used before transfer, so as to remove those silly boot2 3.x images (and thereby save more than 1 MB of usable space on your calculator).
Yep that part I did figure out just did not know where to find 1.4 The download links on this website seem to be no longer active...QuoteWhere can I find 1.4?It's embedded in OS 1.7.2741, for instance, and you can retrieve it with pretty much any program able to decompress ZIP files: Nspire OS updates are just ZIP files with an extra header ignored by most tools :)
Boot2 1.4 can be downloaded here:

You then need to send it to your TI-Nspire using a software supporting the Xmodem protocol.
Ancient Windows versions used to come with HyperTerminal (removed in Windows 7 - don't know about Vista).
