cannot boot, Issue with Controlx

My calculator claims it is on 4.5.1! I guess I misclicked. Oh well. Too late, right?

BTW my files are all still there, but I don't want to click on ndless as I am apparently now on an unexploitable version of the software

I have still boot2 images on my device per the controlx instructions (tinspirecx_boot2_4.0.2.49.img and tinspirecx_boot2_4.4.0.8.img in a documents folder)

If you did install OS 4.5.1 without checking/fixing what's wrong with nBoot/ControlX, yes it's too late.

Ok. Thanks. Does that mean that I am stuck with reduced memory because the partition is permanently locked off?

Yes, until an Ndless installer gets released for OS 4.5.1 or 4.5.2.

any sense of the likelyhood of that? Thanks for the help btw.

Currently, very low as far as I know.

It may take several months, it might take several years...

For completeness:

Windows will not install the libusb-win32 driver on its own, AFAIK. And the libusb-win32 driver can be made to work without interfering with TI's software (and vice-versa), as long as they are executing in mutual exclusion when the calculator is connected (of course), as described in the README.

I am a grad student and this calculator is essentially my toy (I have the CAS if I need it, and I havent taken a standardized exam that allows graphing calculators in a decade). I can accept some risk of bricking it. With that in mind, is it feasible to reflash boot2 via ttl?

Preliminarily, It looks like you can (I can read it at 115200 baud at least), but that the version check is still done completely within in the OS, so it will refuse an older os anyway?
