Sometimes when TI-Connect won't work for me, switching the USB port that my cable is in will fix the problem.

Spoiler For Projects:

My projects haven't been worked on in a while, so they're all on hiatus for the time being. I do hope to eventually return to them in some form or another...

Spoiler For Pokemon TI:
Axe port of Pokemon Red/Blue to the 83+/84+ family. On hold.

Spoiler For Nostalgia:
My big personal project, an original RPG about dimensional travel and a few heroes tasked with saving the world.
Coding-wise, on hold, but I am re-working the story.

Spoiler For Finale's Super Insane Tunnel Pack of Doom:
I will be combining Blur and Collision Course into a single gamepack. On hold.

Spoiler For Nostalgia Origins: Sky's Story:
Prequel to Nostalgia. On hold, especially while the story is re-worked.

I've tryed that for abouth 30 times now. I know TI-connect

EDIT: I can't even downgrade: When I try to send an other OS, My calc says that there was an error, and I should press any key to turn it of. DOES THAT MEAN I CAN'T DOWNLOAD ANYTHING ON MY CALC ANYMORE?

thepenguin77 posted somewhere instructions to fix TI-Connect, trying to find it now...  It helped me a lot.

EDIT:  found two, try first one first.

Quote
-Try new batteries
-Plug in calculator, open device manager, find the calculator, right click>uninstall, replug your calculator into that specific usb port
-Lastly, do step 2 again, but before replugging your calculator, reinstall ti-connect.

If you are going to use TiLP, don't expect to be able to fall back on ti-connect. TiLP makes installing ti-connect twice as hard. Your problem could be related to low batteries, but here's a nearly sure way to get ti-connect working again.

1. Plug in your calculator
2. Go to device explorer and uninstall it
3. Repeat 1 and 2 for any port you think you may have plugged your calc into
4. Uninstall ti-connect
5. Go to your drivers, and delete libusb0
6. Restart computer
7. Reinstall ti-connect
8. Plug calculator in and let it install
9. It should work

It doesn't tell when to unplug the calc, though ???

Also ben_g, if in any case you run into a copy of OS 2.71MP, don't install it. :P

Yunhua98, just be sure to remember that the driver you delete is only for 32 bit operating systems. I don't know which ones you would want to delete on a 64 bit one though because I haven't had trouble yet.

The only way I got TI-connect back to work, was by borrowing a calc from my friend, backup all programs, reset the full memory, and downgrading to 2.40, and TI-connect worked again

@ben_g: Ti connect also has trouble linking to a calc when it's batteries are low. A change of batteries may have fixed things entirely.

yea, but not like this. to me, this always happens:
TI-connect can't find the divice
OR: ti-divice detected, but couldn't get status
But now, it connects as it should, and when I send something to it, it starts the transfer, interrupts the transfer and says 'ti-device detected, but couldn't get status'. I never had this with my previous OS

EDIT: now it says 'transfer failed, a retry may be succesfull', but a retry isn't sucessfull, nor a 10th retry...
I got the same problem can someone help me?

Hopefully, I wrote an awesome tutorial on Ti-Connect, which can be found here.

Yup I followed it and it doesnt work. I was wondering if someone can send me a ti 84 + SE back up file so I can load it onto mine because whenever I turn it on it says Waiting....
Please install operating system now. Then when I press a key it says ERROR! Press any key to turn unit off. Then turn unit back on.

EDIT: It actually loads to 100% on the OS transfer then it gives me an error message.

I got 1.03 :( Yet I still downgraded
Thenyanpeople, you said in another thread that you are running boot code 1.03.  Is this correct? If that is the case, then you need to:

 1) Send OS 2.55MP to your calculator available at http://education.ti.com/calculators/downloads/US/Software/Detail?id=6014&ref=%2fcalculators%2fdownloads%2fUS%2fSoftware%2fSearch%2fResults%3fcp%3d2%23view-1.

 2) Transfer ThePenguin77's program called unsigned available at http://ourl.ca/12713 or BrandonW's program called EpicFail (located on BrandonW's site; not sure if I should post a link...) to your calculator.

 3) Run the program with the Asm( command.

 4) If you are using ThePenguin's utility, select Unsigned OS and input a certificate revision; if you are using EpicFail, select yes both times after waiting for the MD5 hash to validate (note: this program modifies the actual boot code itself, so be warned).

 5) Re-send OS 2.43 (or whatever OS you like) to your calculator.

Hopefully this helps!
Cheers!
I beta test, so...yeah.  PM me if you want me to test anything :D.

Almost only counts in horseshoes and handgrenades.

Cogito ergo sum.

Calcs:
TI-84+, OS 2.43, Boot Code 1.02, 128k RAM
TI-84+SE VSC, OS 2.43, Boot Code 1.00, 128k RAM  (I'm spoiled :P)
TI-81, OS 1.6K (only borrowed)
Casio fx-CG10 (Prizm), OS 01.04.0200
TI-Nspire Clickpad, OS 1.4
TI-Nspire Clickpad, OS 3.1.0.392
TI-Nspire CAS Clickpad, OS 1.6.10110 (!?) now OS 3.1.0.392

Alternatively, BrandonW also created a modified 2.43 .8xu to be accepted by 1.03, which means you don't have to go through the risks of boot-code modding.

A simple workaround for people who have both a Mac and a PC: I could not get Windows TI-CONNECT to talk to my TI-92+, not my Win 8 PC and not my Win 7 laptop.  But the Mac  TI Connect software worked fine with my TI Silverlink USB cable.
