These keys are DER-encoded, which is as simple as base64 encoding them and adding start and end of RSA key headers to the base64. Then, at 0x0126 until 0x0233, the second public RSA key is found. The more recent 4.5.5 version isnt supported so far, neither by Ndless, nor by nLoader. 4.5.4 is the highest version supported by both nLoader and Ndless. If not, you just have to update nLoader first. It is preceded and followed by four bytes, which are 02 AE 01 0E. If nLoader is up to date (2021 April for the last build), you may update your calculator up to version 4.5.4. In manifest.cer at 0x14 until 0x0121, the first public RSA key is found. Not sure if this adds anything to your findings, but I thought I'd share it anyway. I found two public keys in manifest.cer (which, by the way, remains the exact same between 5.3.0.564 and 5.4.0.259, perhaps even before then), which are: Public Key 1 Public Key 2 I also included other things about the key, if it helps any. ![]() This makes sense as when I open it is 7-zip some of the files are missing and the other ones show that they have been edited (although I think I have figured out the crc records) and like LambdaLaboratories said distruibution TI software (without permition and we all though thats not happening) is illegal so if you want more "Information" I will post it on the chat room on my website (It does not liik the best but I can promise the security is pretty good (it has had some "real world" testing but thats another story) anyway im rambling, but I will post some things on there (room name: ndless) showing what I have done so maby some other poeple could look at what I have done and contruibute to this.Ĭould you elaborate how you got the keys from the file? i had no succes opening it in any way The software still accepts (or thinks) thats its the newest version but stops and says the file is corrupt. The most recent thing I have done with it is replace the OS and certifactes entirely only editing the os version info from the manifest.txt file. If you are currently running 4.5.1 or 4.5.2, you need to upgrade to that version of 4.5.3.Sorry, I have not made much progress lately I have a large project in school this month so will likely not make much more progress until december. To avoid this needless formatting, you can download just the plain OS from a mirror on : CX and CX CAS.

While the biggest change is obviously the support for the CX II models and operating systems, users of later CX calculators (HW revision W and up) can now enjoy a better LCD compatibility mode, with much better application support and performance. ![]() The common filenames for the programs installer are IconE8EDF6091.exe, TI-Diagnostic.exe or TI-NspireCAS.exe etc. We cannot confirm if there is a free download of this software available. AK and later.įor completeness, this is the changelog for r2015: TI-Nspire CAS Student Software 3.9.0.463 was available to download from the developers website when we last checked. It introduces compatibility with the "capTIvate" touchpads found on CX II models with HW rev.
