Yes, I did.

I'm sorry, I'm quite busy this week-end and cannot investigate this for the moment.

Just flashed, still on a CR4+/W+ CX CAS.
Didn't have to patch the images for BtMg this time, thank you.

Yes, I'm getting a little more 'progressive' progress bar, and it still works and auto-installs Ndless.
Note the lock icon isn't shown anymore.

If you want, I can help you to try your program. I have too Nspire CX CAS, but no HW-W+ Nspire.
Sorry :?

No problem, we need tests on real hardware for revisions A-V too.

  • you need to have Boot1.5 4.4 as the 1st image in your Boot2 partition - usually the case if you've updated to 4.4/4.5 - check with BtMg
  • then with BtMg, flash either the nanoloaderCAS_OS.img.tns or nanoloaderNONCAS_OS.img.tns available at https://github.com/parrotgeek1/TI-Nspir ... boot15_exp as 2nd image in your Boot2 partition

I'd advise you to extend your Diags partition with nsPartManagik before, and put a valid Boot2 image as the 1st image in your Diags partition.
To still be able to boot if something goes wrong.

Note that this *must not* be performed over an nBoot installation.
Some things may interfere - not checked for now.

@parrotgeek1
Here's a new unlisted video.

It's better, but the progress bar still seems to jump directly from 25% to 50%.
Are you sure you specified the right values ?

For reference, in the read_nand/Boot1/Boot2 context : 0%=0, 25%=50, 50%=100, 100%=200.
