Hello guys, I broke my Boot2 trying to downgrade the OS 3.6 to OS 3.2 CAS...So I tried to connect my Ti by TTL but the hyperterminal don't works, don't connect. I have a conversor with PL2303HX chip, this:

Q1) So, is because of this chip PL2303HX I can't connect or other thing?
Q2) I need to buy a specific conversor with FTDI chip to connect my Ti and recovering my boot2?
Q3) Can I put the Boot2 v1.4?

How? What did you do?

Try to connect only the RX and GND pins first.
With 115200 Baud you should get at least some traffic from boot1.
Q3) Can I put the Boot2 v1.4?
No, won't work. v1.4 is for touch and clickpad only.

First, thanks for your Help!
How? What did you do?
I tryied this: http://www.omnimaga.org/general-calculator-help/installing-cas-on-ti-nspire-cx-non-cas/msg383792/#msg383792 (http://www.omnimaga.org/general-calculator-help/installing-cas-on-ti-nspire-cx-non-cas/msg383792/#msg383792)
and don't change de hole name, the extesion .tcc to .tns, just de first name.
Try to connect only the RX and GND pins first.With 115200 Baud you should get at least some traffic from boot1.
Didn't connect, neither in RX or TX!
My conversor can be broke? when I connect TxD, RxD and GND don't light the yellow light, just de Blue and Red, the yellow becomes weak!
No, won't work. v1.4 is for touch and clickpad only.
What I do?

It was rejected, I assume. Did you do anything with nsNandMgr?

What do you mean by "didn't connect"? After you open the serial port nothing happens?
Try to connect GND and RX only.
No, won't work. v1.4 is for touch and clickpad only.
What I do?
After you got your calc in a usable state, do a normal installation of the 3.6 CX OS.

No, I just did the Tuto.

When I try to connect with the hyperterminal show me that i'm connected but don't show me nothing in the screen, like this:

And I already tryied to connect with RX and GND, nothing happens.
After you got your calc in a usable state, do a normal installation of the 3.6 CX OS.
So I can't put OS's with CAS anyway?
One more doubt, my Ti has the number 1 in the right side, it's normal or I need to invert my connections?
Thanks man!

Yeah, either you're using the wrong pins or your adapter is fried.

No, your calc doesn't support nlaunch.

Well, Pin 1 is Pin 1. The serial pins are on the left side if the calculator is facing downwards and the port points to you.

I'm think the adapter isn't working, because I tryied in 3, 4 and 5 conectors in left and right side.
No, your calc doesn't support nlaunch.
So I need put de Boot2 V3.1 to the calculator work again?
Well, Pin 1 is Pin 1. The serial pins are on the left side if the calculator is facing downwards and the port points to you.
Look my calculator:

What do you think?
thanks again! so much!

Yes, you need to.

Connect GND to the longer pin on the left side and RX of your adapter to the left pin next to it.
-
Yes, you need to.
Ok. thanks for that part.

Still didn't happened nothing on hyperterminal, is the conversor. I already asked other for the seller. When arrive the new I try again.
Q) When I put the Boot2 V3.1 I need reinstal the OS? Or I just Turn on the calculator?
-
You need to reinstall the OS, I think. But you can just turn the calc on and see what happens; if you need to reinstall the OS, the calc will probably warn you
or explode

solved , I put Boot2 v3.2.4.7 and returned to run OS 3.6.0.550 . thanks to those who helped .
