新入CM-CAS，OS是最新版的3.2，请问该如何降级到3.1刷入ndless，论坛上没有搜索到相关的步骤，置顶帖也是针对其它机型，一头雾水，不敢随便刷，怕砖。

Hi !

Just download CM CAS OS 3.1 and send it to the calculator :

There is no downgrade protection against this in version 3.2.0.
You won't brick the calculator just like this. ;)

I managed downgrading the calculator and installing ndless somehow by googling. Your information is much appreciated however.
Most ndless dependent utilities and games run well except for GBA emulation. I am wondering whether this is related to the RAM size of CM-C CAS.
