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

Edit: WOOT! 1337 posts! 

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.

-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

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.

@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.

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!

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.

Where can I download it?, Because I'm looking for

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.
