System error on every boot, reformatting not helping

→ **MyCalcs** profile · by **felipe oliveira** » 11 Nov 2014, 15:59

When I put the v.3.2 boot2 I have to turn the calculator on and uninstall the OS without it start ? or I can simply let it start it will turn normal?

Could you post the link of boot2 v3.2? because I have not found.

Thanks again...

If you already destroyed your calculator's boot2 by going through a dangerous tutorial on another site (is that what you really did ? Do you see the system error message now ?), then you do indeed need to reflash boot2 3.2.4.7. Only that version will work for your calculator.

What are you trying to do ?

In which state is your calculator currently ?

I did this tuto but I didn't change the whole name:
http://www.omnimaga.org/general-calcula ... #msg383792

So I think that I brick the boot2 and now I have "system error" in my screen.

Could you please explain step-by-step what I need to do?

Ok - so it's not your fault, but the Omnimaga tuto is outdated and wrong, and made you destroy your calculator.

There is no software way to repair it.

You need to buy an USB/TTL interface, to connect it to the Dock/J01 connector like below, to hold

while pressing and releasing the reset button, and to send the Boot2 3.2.4.7 image file with an RS232 compatible terminal software like hyperterm for Windows :

After Boot2 3.2.4.7 has been sent successfully, the calculator is just going to reboot into the OS.
There is nothing special to do after this.

Yup, turn on the calculator, and if needed, reinstall a suitable OS, either 3.6.0.546/550 if you still can, or 3.9.0.461/463 (if that's what you had before).
TNOC does not work on those OS versions, TI did something to break TNOC.
