Hi,
Today, my friend robbed my CX CAS and opened 'nsNandMgr' , which i used to downgrade to OS 3.6, however, when my calculator come back to my hand, it stuck at diagnosis mode. So i pressed reset, and it rebooted to Diagnosis Mode, i know he must 'switch BOOT2 AND DIAG' in the BootD AREA. So in the diagnosis mode, i pressed '0' '1' which is 'Switch to OS Mode' ,and i pressed reset again , it started booting.
Then the booting UI turned into this (showed in picture)
What i had tried are :reinstalled the OS , Clear boot2 and flash boot2 again. These are all useless.

So how to change the LAUNCHING ANIMATION back to it used to be？
Thank you.

我也见过这个现象。我有个同学的Nspire的开机页面也是这样的，同求原因。

我估计是manuf区块被破坏了。这个分区被破坏了之后不好还原的
KARMTI就是因为没有完整的manuf区块所以开机界面也是这个鬼样子

这是我从自己的L版Nspire CX CAS dump出来的manuf区块数据，不确定能否用nsNandMgr刷入其它Nspire CX (CAS)
（注：刷完之后可能会变成CX-C CAS，模拟器测试结果）

Manuf blocks haven't been destroyed.
It's just that nsNandMgr has an option to clean Boot graphics.

You just need to download a manuf image including the Boot graphics you'd like to have :

Send it to the calculator in the "/ndless/" directory, rename it to "manuf.img" and reflash it in the "4) Manuf area" menu.

BTW, is there any tutorial or instruction of mySpire to create the manuf with my pictures? :P

You cannot inject your own pictures, unfortunately, because of the data block signature.

You can just move/resize/distort pictures already present in the TI manuf images data block.

How to open img?

You need to dump the Manuf area using nsNandMgr.
This is going to create a /documents/ndless/manuf.img file.

Just open that file with mySpire.
You'll be able to customize the boot graphics elements options and preview the resulting screen.

Again, no.
The Boot1 and Boot2 are never going to accept this, because of the manuf.img data block signature we are unable to calculate properly (2048-bits encrypted... ).
