我的一个Cas也是刷到1.7版本正常,再升级到3.1.0.192后也是无法启动,停止在一半的画面。怎么解决?

咦楼主你删了系统……
这下糟糕了吧、
除非是本来的系统(或者是系统版本更旧的?)


拆开壳子后再数据线上看到了EVT的字样。原来什么版本忘记了,我升级到1.7版本时还是正常的。升级到3.1后启动就如楼主这样的画面停止了。怎么解决呢?

TTL接口位置在哪里?

Apparently, the new 3.1 OS tried to update your Boot2 1.4 to version 3.0.1, an the update did fail. :(

So no valid Boot2 anymore, your calculator is now totally unusable. :(

You need to reflash a valid Boot2 image.
USB isn't functionnal in such an advanced bricking state, so you'll need to connect a TTL interface to the Dock/J01 connector :

If you want, I've uploaded the 1.5.DEVBUILD OS for TI Nspire non-CAS on Ti-Planet.

Now you can, normally, updgrade your Nspire non-CAS with a development OS ;)
