Nspire CX - cannot launch NsPartManagic

[the2048]

Hello! I have recently pulled my Nspire CX out of storage only to find that I have seemingly... broken the bootloader somehow. Here's the breakdown:

- ControlX and Linux were installed, however are seemingly gone now.
- Upon powering on the calculator, it boots into a monochrome "TI-nspire" boot screen, and boots normally to the CX OS.
- Ndless for OS 4.5.4 installs fine, most apps run fine, as long as they expect less than 32 MB of RAM.
- However, upon running nsPartManagic, the calculator freezes up and I have to reset it to continue.
- nsNandMgr and BtMg do not launch with the error of "Not enough memory."
nsNandMgr requests 64.8 MB and manages to allocate 0 MB, BtMg requests 32.4 MB and also manages to allocate 0 MB. Downgrading is seemingly not possible, because I cannot install any bootloader software to lower the minimum version.
I have tried to restore the diags partition (and additionally boot2) over RS232, but to no avail, this did not work.
Is my only option to either attempt to restore the partitions again, or send the calculator in?

Thanks in advance.

Hello.

Thank you for your comprehensive post.

In your case, it seems a huge Boot2/Diags partition is making BtMg/nsNandMgr abort, and making nsPartManagic crash.
I need to check the nsPartManagic source code.
