急！求助CXOS3.6如何刷回3.1？

今天手贱，用Nlaunchy想刷个CAS3.6的双系统的，结果发现刷完之后无限菊花，删除系统想要重刷3.1的时候发现已经晚了……现在只能刷了3.6先用着。现求助boot2如何降回去？没有NDLESS实在不爽啊。
虽然我都觉得没啥可能降回去……

由于提升了最小系统安装限制目前已经没办法了
不过你BOOT2还是低版本的么？是的话参考这里

不是的话那么很遗憾无法降级了

杯具了，期待法国人和Ti内鬼多努力吧。

If you've got OS 3.6 with Boot2 3.1, just install Nlaunch and you'll be able to downgrade easily.

If you've got Boot2 3.2.4 on a hardware revision A to I, you'll need an external USB/TTL interface in order to reflash Boot2 3.1 first.

If you've got Boot2 3.2.4 on hardware revision J or above, there is no known way to downgrade yet.

Do you have a tutorial to use a TTL cable to downgrade? It seems that I can't find one in the forum.
