I mean brick it with the OS

first time that i hear about tnoc, could be possible that with the os 3.0 installed, can i downgrade my os to 2.1 versión???

Welcome on the forums. Sadly if you installed OS 3.0 before modifying its content with TNOC, it's too late. You would have to use this.

i have a question about de .TNC format of the OS files, it can be opened and extracted by 7-zip, it means like a compresed file, 7-zip recognize this files like one of its suported formats of compresion, i mean, ¿which is the compresión format of the .TNC files? i tested TNOC and this program can operate into this compresión format deleting archives, i think that if a .TNC file is modified replacing its boot2.img file with the boot2.img file of an older versión and be instaled in the handheld, it will modify the boot2 sector of the handheld to this older versión, if somebody knows the compresión format please answer my question, is a theory but i would like to try it.

goodbye and thank you for help

We've allready tried last year.

You cannot downgrade the boot2 by using a TNC/TNO file, as the OS will only rewrite the boot2 area if the included boot2.img file has a higher version number.

Is it possible to change the version number, or do we need the RSA keys in order to do that?

We need the RSA keys.
It would have been too easy...

I'm pissed at 2.0 right now because it crashes all my ARM executables on launch like gbc4nspire and NESpire.

Complaining about an OS update that no one forced you to install dosen't help anyone.
That said, can't you just recompile them with the ndless 2 source? It works fine for me.

BrownyTCat, change your attitude please. You are being rude to those who devoted lots of time and effort on Ndless. You should be lucky Ndless even exists. Telling developers you're pissed at their new version because it doesn't work for you and yelling at nDoom developers because it doesn't run on 1.7 is certainly not going to gain you a lot of respect in this community. These people deserve more respect from you for even allowing these tools to exist.

Also, these people have a life, so it's inevitable that it will take a long while before every bug are fixed. In fact, I think nDoom project is dead due to lack of time. On a side note, it's remarks like yours that can kill these projects or slow them down in development, in some cases.

I have rated down your post, and I think you should change your manners towards us. Have respect for those who devote time and energy to develop programs for you out of their limited free time.
