[新手求助]CXCAS在3.6下用nsNandMgr干掉了Boot2

zengpinyi

现在一直麻点屏，时钟不转
急救模式重刷过了，无效

另外之前还改了区域，变成了CXC
出现这种情况，是不是必须上TTL了?

恭喜砖了：（

我记得有个砖机修复教程啊

卧槽这奖中得猝不及防
才刚买来不久，这么贵的东西弄砖，估计有麻烦了(尽管它是我的)
听你这么一说，估计只能作死上TTL了(没记错的话接错会真砖)

If you did attempt to flash a Boot2 version incompatible with your hardware revision, it's perfectly normal.
For example, Boot2 3.1 won't work on hardware revisions J+.

All up to date tutorials are warning you against this.


You can fix your calculator by reflashing a compatible Boot2 version with an USB/TTL interface :

Educated, thank you!
It is a machine that has been brushed into the 4.2 D version of the machine, do you have a wish to downgrade 3.1?

If it's hardware revision D, then Boot2 3.1 should have worked.

What's the current problem/state ?

In the event of problems it has been stuck in pitting the screen before the system is ready , and the clock is not spinning cursor . Now it had run out of battery .
I just want to try to run the 3.1 version of the operating system , is this possible?

Ah, that's not a brick, it's a bug.
A bug which can happen on all color TI-Nspire, even without the use of Ndless tools.

Launch the Diags software to fix the problem :
- plug your calculator to an USB power source
- press and hold the reset button
- without releasing it, press and hold Esc+Menu+Minus
- without releasing them, release the reset button (calculator should automatically turn on - if not, press On)
- release all keys

The calculator should automatically start the Diags software, which should report you a GPIO error.
Confirm the fix with the Esc button.

Once you reach the Diags main menu, press 'reset' and your OS should start normally. :)



If your calculator has a hardware revision between A and I, yes OS 3.1 once installed should work perfectly. :)

Thank you very much, although the diagnosis did not report "GPIO errors", but after the reset problem-solving.
Do you have the Ti-nspire CX CAS from OS4.2 to OS3.6 or OS3.1 tutorial?

Thank you, with the help of nsNandMgr, I successfully repaired the machine, and downgraded to OS3.6.

抱歉还有我.
我也是刀掉了boot2,现在一开机就自检
不管选哪个还是自检
