Adria T. has joined this session.
from Adria T. to All Participants:
Thank you Gareth for contacting TI Cares Support, my name is Adria. How can I help you?
from Hayden G. to All Participants:
So I have a TI-84 Plus CE
from Hayden G. to All Participants:
And I downgraded from OS 5.6
from Hayden G. to All Participants:
I installed OS 5.4.0
from Hayden G. to All Participants:
Is 5.4.0 a stable OS?
from Adria T. to All Participants:
I understand you need assistance with the OS on your graphing calculator. I would be happy to assist you.
from Hayden G. to All Participants:
So OS 5.6 discontunes native code and prevents downgrades, right?
from Adria T. to All Participants:
Gareth, once your calculator has a newer version of the OS, you should not be able to downgrade the OS. Did you use a third party app to do this?
from Hayden G. to All Participants:
No
from Hayden G. to All Participants:
I used Cabri Junior from your website
from Adria T. to All Participants:
The current configuration does not allow for downgrading with our tools. If a calculator was successfully downgraded, we cannot guarantee its functionality.
from Hayden G. to All Participants:
It was downgraded by a bug in the software.
from Adria T. to All Participants:
Cabri Jr will not downgrade the OS. Is this the app version?
from Hayden G. to All Participants:
Yess
from Hayden G. to All Participants:
5.6
from Adria T. to All Participants:
The current version of Cabri Jr is 5.0
from Hayden G. to All Participants:
Oh
from Hayden G. to All Participants:
https://education.ti.com/en/software/de ... bri-jr-appfrom Hayden G. to All Participants:
This exploits a bug that enables native code, which allows the OS to be downgraded
from Hayden G. to All Participants:
By changing the certificate min OS version
from Adria T. to All Participants:
One moment while I review this information.
from Hayden G. to All Participants:
Sure thing
from Hayden G. to All Participants:
Hopefully this is fixed
from Hayden G. to All Participants:
You disallowed assembly for a good reason, arTIfiCE.8xv makes it so you can downgrade and run assembly programs
from Hayden G. to All Participants:
Here is more information about this:
https://www.cemetech.net/news/2020/9/95 ... de-for-nowfrom Adria T. to All Participants:
Gareth, I thank you for this information. I am going to pass this information on to my development team.
from Hayden G. to All Participants:
You're welcome, did you look at the Cemetech page?
from Adria T. to All Participants:
If you install the OS/app bundle from our website that will put the current version of everything on the calculator.
from Hayden G. to All Participants:
Ok. Will do.
from Adria T. to All Participants:
I am going to pass the Cemetech page on to my development team.
from Hayden G. to All Participants:
Is this llegal for people to find these kind of bugs?
from Adria T. to All Participants:
arTIfiCE.8xv is not ours.
from Hayden G. to All Participants:
Of course it's not
from Hayden G. to All Participants:
It's a custom made shell that runs all assembly programs
from Adria T. to All Participants:
Again, I am passing along your information to our development team.
from Adria T. to All Participants:
Is there anything else that I can help you with today?
from Hayden G. to All Participants:
Nothing else, just reporting this so people will stop doing this crap to break the rules
from Adria T. to All Participants:
I understand and appreciate your assistance in this matter.
from Hayden G. to All Participants:
Thank you for understanding, will you email me what the dev team thinks about this info to me please? I'd appreciate it so I can inform others on Cemetech that so TI knows about this
from Adria T. to All Participants:
Our development team does not directly inform individuals of what determinations are made because a variety of factors go into their decisions. I will not be informed of decisions they make regarding the information you have provided.
from Hayden G. to All Participants:
I understand
from Hayden G. to All Participants:
Thank you for your time
from Hayden G. to All Participants:
Goodbye for now.
