8 reported bricked TI-Nspire since the OS 3.0 release up to now...


How many reports untill TI removes OS 3.0 from the servers?

Levak has just discovered that OS 3.0 is overclocking the hardware even further:

Core = 264MHz (240MHz with the 2.1 OS - 180MHz with previous OSes)
CPU = 132MHz (120MHz with the 2.1 OS - 90MHz with previous OSes)
AHB = 33MHz


It might be possible that the overclock does help the boot2 flashing failure to occur...

If TI bricks are calcs with their software can we get replacements for free or would we need to fix it on our own?

If it's still under warranty, they'll repair/replace it for free. If not, I doubt they'll admit it's their fault.

That's why I've asked if someone who "understands" the decrypted OS was seeing any trace/proof of this major bug in the 3.0 OS boot2 update code.

Triple posting, but... it's really really bad!

I'm missing words to describe TI stupidity.

We got another answer on the topic:

The user could boot OS 3.0 one time but not 2 times, which is perfectly normal as the boot2 is only updated after the 1st OS successfull boot.

So something went wrong during the boot2 update and the boot2 was destroyed.

OS 3.0 is destroying calculators because of the new boot2 whose only goal is to prevent you from downgrading and installing Ndless.


Because of previous reports, it seems this boot2 update bug is present since at least OS 2.0.0.

You should not install OS 3.0...
And you MUST NOT install boot2 3.0! Use TNOC to save your calculator from dying!!!...


Does anybody have a clearer idea of what can go wrong during the boot2 update? Golat? Bsl?

The 3.0 OS being just crap wouldn't be a problem if it wasn't installed allmost automatically and if you could uninstall it.


I have no proof, but I really think that there is some random bug in the boot2 update code since the 2.0.0 OS.

Check here -> http://tibank.forumactif.com/t6932-l-hecatombe-des-boot2#109963

3 different persons have reported deleted boot2 since last week (this hadn't been reported for months - we had several similar reports after the 2.0.0 OS release and then nothing else...).


When the boot2 is missing, the calculator stays stucked at the following screen:



Without the boot2, you cannot use the USB plug. You can only repair the calculator using my external RS232 interface.


Has someone any idea of what can trigger this major bug? Does the 3.0 OS really randomly destroy TI-Nspire calculators?

I'd need some proof before newsing...

OS 3.0 == crap

* According to the readme, it does not support TI-Nspire. Does this mean it won't work with the Nspire 84+ keypad?
If it doesn't work, I'd like to know why... The RAM & ROM are here... I thought only applications dealing with the USB port had problems....

It uses undocumented z80 commands that the emulator doesn't support. Also, it modifies flash directly, which isn't allowed by the emulator.

Thanks for the clarification.
I thought Brandon had found a way to unlock the flash with 84+ keypads...
