Yes I turned on my calc and I was greeted by a install OS now? I try to send one with ti-connect but it cant find my device?
Well TI was no help with their guidebook Ill ask ti-cares
-
You can try TILP but it is sometimes a PITA to get working. Never seen a new calc need an os install, maybe TI decided to save money by only flashing the boot pages.
-
TILP doesnt work for me I dont know how to use DOS very well
-
TilP can handle OSes just fine. I strongly recommend going USB for it, since it's much faster. However, if you have a silverlink it's worth a try since they're a little easier to keep connected.
Was it actually new, or just new to you, and used?
-
New bought from best buy ok not silverlink I will try after testing flash is over
-
Does it stay on there? If you turn it off and turn it back on, is it still there?
Also what does it say? Tho I'm guessing it's the screen from the del+battery trick..

Yes it is

It really doesn't matter. Either way, he'll still need to wait six or more minutes for it to validate.

I am lost :'( I have to give my old 84 SE back to my teacher and this wont work :'(
-
Six minutes? 0.o I've re-sent OSes and it takes about three seconds to validate...
(that with usb btw)
I'm guessing it takes longer when all that exists at the start is the boot, then?
-
Remember, you can only install 2.55MP, because you can't downgrade the boot code until you first install an OS.
-
So boot 1.03 goes through a longer, more complicated (and more secure I guess) process? Fun...
-
I dont know I need someone to phyically install the OS for me (maybe my dad) but I am at my grandmas :banghead:
400th post and I dont care because I want my calc to work
-
Hm..does OS transfer between two calc of different boots work? (Tho the OS would have to be 2.55 x.x)

You missed the news frenzy that resulted when we learned about 1.03? TI switched to 2048-bit RSA. The new signature is tacked onto the end of the 2.55MP image; it's been there this whole time. Also, they actually managed to write an even slower validation routine. They're rolling 1.03 out for the new school year. This move prompted an intense frenzy of research that resulted in us discovering how to reflash the boot code, thus completely negating the change.
400th post and I dont care
Neither do I care about how many posts you have.
-
Well I remember all the stuff happening (84 pocket having it initially, other 84s coming with it, and the resulting unlock exploit) but I just don't remember a good part of the details :P
Anyway @annoyingorange what OS do you have on your older calc? I'm assuming a link cable came with the new one..

oh I dont want to upgrade though because truvid wont work then
EDIT I have OS 2.53 on my other calc
-

That should work.
oh I dont want to upgrade though because truvid wont work then
So install 2.55MP, downgrade the boot code to 1.02, and install 2.43 or whatever you want.

Ok ill do that but how do you dowgrade the boot code?
-
Sorry to double post I upgraded my OS on my other calc then sent it I am ok should I lock the topic?
-
you don't need to. Locking the topic is only necessary to prevent people from posting. There's no reason to if you're just done with it.
-
Ok Ill leave it unlocked I am happy now My calc works :D now to stiff it with programs :D
-
Btw as for boot code downgrading: http://ourl.ca/11891/224479
With this you could downgrade both calcs to your OS of choice :)

Great!
