Huh? The only screenshot I see in the tutorial is of WinRAR. Did you use WinRar to send the file?

The TNOC tutorial doesn't deal with Boot2 reflashing.
I've made several tutorials about that.

Check this one for example:

Hi, just got my Nspire touchpad (non-CAS) a few days ago. I connected it and it installed the new OS. I am trying to get ndless but I know I cant without 2.0.1 or 2.1. The reason I am posting this here is because whenever I click on a link to "ti.bank.free.fr" I get this message:

The server understood the request but is refusing to fulfill. An authentication process will not help and the request should not be renewed. If the invoked method is different from HEAD and the server wishes to make public why he refuses treatment, he will do in the entity associated with this response. This status code is often used when the server does not wish to dwell on the reasons for refusing access, or because it's the only answer that works. You are trying to access a resource to you prohibited. It may be that the relevant account is suspended (see Management Console)

I am trying to get TNOC to remove boot2 so I can downgrade to 2.1 so I can get ndless.

Yeah TI-BANK was taken down by their hosting provider for having too many files and using too much server ressources or something like that. Not sure when it will come back.

Critor should probably put TNOC somewhere or update the version on ticalc.org for OS 3.0.1 if not already done.

Welcome on the forums by the way! :)

pillyg: if you have already installed OS 3.0.1.1753 or 3.0.2.1791 without having used TNOC first on the TNO, you cannot downgrade your calculator anymore without special hardware (which enables you to reflash the boot2).
IOW, in the current state of things, it's very likely that you cannot get Ndless.

Indeed, it still won't work until you reflash the boot2 through the serial port, or Ndless 3.x is released.

"No", in that not much will be posted publicly for the reason that TI is still very much trying to fight against the inevitable :)

So, how does an OS know if a supplied boot2 is "older" or newer? after all, they're signed with the same key. perhaps you could package a 1.4 boot2 into the 3.0 OS file. Thoughts?

I guess I should compile TNOC 1.22 for Windows but since it is a way too hard to solve zlib stuff problems under windows I've never done it, even if there are many bug-fix ... =/

Maybe, but then the result could be redistributed only under the form of binary patches, because third parties are not supposed to redistribute TI's binaries :)
That's how tiosmod+amspatch works for those who do not compile and use it themselves: four different formats of binary patches.

sure, but heck, if it meant getting back the boot2 without an rs232 mod, a patch isn't bad at all.
