Do I want KhiCAS and how do I install it (and other external applications)? | Omega Community | Page 1

zealous orbit Sep 15, 2022, 1:57 AM

#

Title says it all, my calculator no longer connects to the website, but appears to be running on Omega?

#

Epsilon 15.5.0 - Omega 2.0.2

#

This is what the page looks like

#

I originally put "Morata" in the username slot and it appeared to work?

#

I'm just trying to figure out how I get the dark modes, KhiCAS which I think is what I'm looking for, etc.

#

zealous orbit Sep 15, 2022, 4:47 AM

#

So yeah, I opened up the dualbooter and my original firmware is gone.

#

The OOTB firmware was 15.X.X so this sucks, I don't know if I'll be able to restore that or not

fervent phoenix Sep 15, 2022, 5:13 AM

#

You have 2 tabs using the calculator. Close the one you don't need

zealous orbit Sep 15, 2022, 5:15 AM

#

Yeah, I got KhiCAS installed, but I had no idea what I was doing or pressing, fucked it up, and I'm currently trying to just do a fresh reinstall, but I can't seem to figure that out now

#

Problem is that my original firmware is gone, and I cannot figure out how to reinstall Omega 2.0.2 (currently installed firmware)

#

Never did figure out the themes either 😕

Recovery

zealous orbit Sep 15, 2022, 4:23 PM

#

Calculator doesn’t show up

#

In either mode either

twin berry Sep 15, 2022, 4:24 PM

#

Try to reinstall the driver

#

(https://cdn.numworks.com/81cc6426/numworks-driver-win64.msi)

zealous orbit Sep 15, 2022, 4:25 PM

#

Uninstall it from Device Manager manually first?

twin berry Sep 15, 2022, 4:27 PM

#

Not specifically needed, but I use Arch, so I don't know

zealous orbit Sep 15, 2022, 4:27 PM

#

Ah, gotcha

#

I’ll see what I can figure out and report back when I’m done

twin berry Sep 15, 2022, 4:28 PM

#

I know that Windows update break the driver sometimes…

zealous orbit Sep 15, 2022, 4:47 PM

#

Maybe I should try on my Mac?

zealous orbit Sep 15, 2022, 7:09 PM

#

Unfortunately, this is all I'm getting:

#

I'm honestly not sure how or what I should do

fervent phoenix Sep 15, 2022, 7:10 PM

#

Install

zealous orbit Sep 15, 2022, 7:10 PM

#

Mate, it's already installed

#

Let me screenshot what happens if I click it though

#

#

Instantly, this is what happens.

fervent phoenix Sep 15, 2022, 7:11 PM

#

F12

#

Then console pls

#

Show errors

#

Which version of what?

zealous orbit Sep 15, 2022, 7:12 PM

#

fervent phoenix Sep 15, 2022, 7:13 PM

#

If you doubt, just press reset + 6 and then go to install on omega website but instead of installing, click on recovery

#

Will start recovery procedure and then you should be able to install omega

zealous orbit Sep 15, 2022, 7:13 PM

#

Do I do the reset + 6 while plugged in, or?

fervent phoenix Sep 15, 2022, 7:13 PM

#

Plugged in or not

zealous orbit Sep 15, 2022, 7:13 PM

#

Well, I have omega installed, I'm just trying to reset it

#

And I'm also trying to get an authentic firmware for the dual boot

#

Since my original was corrupted I guess?

#

Just shows as invalid on the dual-booter now

fervent phoenix Sep 15, 2022, 7:14 PM

#

How did you installed the bootloader ?

zealous orbit Sep 15, 2022, 7:14 PM

#

OOTB, it was on 15.X.X

fervent phoenix Sep 15, 2022, 7:14 PM

#

Which version of epsilon ?

#

Whats ootb ?

zealous orbit Sep 15, 2022, 7:14 PM

#

I just used the automatic installer on the site

#

Out of the box

#

I opened it up and it was running 15

#

Which as far as I know, was good (unlocked OOTB)

fervent phoenix Sep 15, 2022, 7:15 PM

#

With omega installes from the website ?

#

What does rest+4 shows you ?

zealous orbit Sep 15, 2022, 7:15 PM

#

So when I originally tried

#

It brought me to the dual boot screen

#

And I had both slots invalid

#

I thought I bricked it

#

Panicked a bit, before trying again and finally, Omega was installed!

#

But my original firmware is gone, and I don't know if I can ever recover that or if I even want to do so necessarily

fervent phoenix Sep 15, 2022, 7:18 PM

#

Try to reinstall following the recovery procedure i explained earlier

zealous orbit Sep 15, 2022, 7:18 PM

#

Does what I put in the username slot matter at all?

fervent phoenix Sep 15, 2022, 7:18 PM

#

Then install omega

fervent phoenix Sep 15, 2022, 7:18 PM

#

zealous orbit Does what I put in the username slot matter at all?

No

zealous orbit Sep 15, 2022, 7:18 PM

#

Gotcha, I've got it in recovery mode

#

I'll keep you posted

#

Working so far 👍

#

If you have a good guide or some resource that can help me understand KhiCAS, that would be great, English or French, but preferably in English. I was having quite the difficult time trying to figure out what I was doing, although it could be a number of reasons. I'm not a programmer, nor have I ever used a CAS system before.

#

I do appreciate the help though

fervent phoenix Sep 15, 2022, 7:21 PM

#

I think there is documentation over xcas which is nearly the same as khicas

zealous orbit Sep 15, 2022, 7:21 PM

#

I saw xCas on the KhiCAS menu, so yeah, that would probably help

#

Is it normal for the bottom bar to be off the screen though? (in KhiCAS on Numworks)

#

Hmm, so on the calculator, it installed, and then gave the connected popup, KhiCAS is still installed, but on my end, the installer bar is fully filled in, but didn't refresh

#

And I'm getting this again

#

Should I reinstall standard firmware, perhaps upgrade to 18.2.0 if I can find it?

#

I feel like such an idiot lol

fervent phoenix Sep 15, 2022, 7:27 PM

#

fervent phoenix What does rest+4 shows you ?

.

zealous orbit Sep 15, 2022, 7:30 PM

#

Let me grab a photo on mobile

#

fervent phoenix Sep 15, 2022, 7:31 PM

#

Does slot 1 works ?

#

If yes, just download the file in pinned messages in #help-en , then unpack it using unpack.py script and then flash external.bin using ti planet webdfu

zealous orbit Sep 15, 2022, 7:33 PM

#

Yes, yes, Omega is installed, I was just trying to A. reset it to default, and B. get my dual boot function back

fervent phoenix Sep 15, 2022, 7:34 PM

zealous orbit Sep 15, 2022, 7:34 PM

Thank you, I was about to ask 😅

fervent phoenix Sep 15, 2022, 7:35 PM

#

fervent phoenix If yes, just download the file in pinned messages in <#663420992009535498> , the...

That's how to get your dual boot back

#

What is reseting to default ?

zealous orbit Sep 15, 2022, 7:36 PM

#

Factory settings, fresh installation

#

The Omega firmware

#

Removing KhiCAS and everything as if I just installed Omega

fervent phoenix Sep 15, 2022, 7:37 PM

#

Just reset at the back of the calculator is a fresh installation

#

Hope i helped you

#

Can't help more

zealous orbit Sep 15, 2022, 7:38 PM

#

Thanks, working on getting the dual boot back

zealous orbit Sep 15, 2022, 7:44 PM

fervent phoenix The script:https://guide.getomega.dev/images/unpack.py

Nvm, we're good. File didn't download correctly originally.

zealous orbit Sep 15, 2022, 8:03 PM

#

WebDFU is taking forever, but we're making progress, data is being written 👍

zealous orbit Sep 15, 2022, 9:37 PM

#

After many failed attempts

#

I've done it

#

Epsilon and Omega dual-boot!

#

Thank you for all the help @fervent phoenix

#

Wouldn't have been possible without you

fervent phoenix Sep 16, 2022, 4:58 AM

#

You're welcome !

zealous orbit Sep 16, 2022, 5:08 AM

#

fervent phoenix You're welcome !

Hey, just a small question, how do I get the themes 😅

#

And also, why is Numworks and/or TI so intensely followed by French folks?

vernal otter Sep 16, 2022, 9:10 PM

#

zealous orbit And also, why is Numworks and/or TI so intensely followed by French folks?

Numworks is originally a French company. They even received an inventiveness award from the French state when they started. And I think that even today, the majority of their market is in France.
For TI, I'm not sure, but maybe it's due to some community sites that bring people together, like TI-planet.

zealous orbit Sep 16, 2022, 9:27 PM

#

Now that makes sense

halcyon hill Sep 16, 2022, 9:30 PM

#

I've actually been having the same issue, although my calculator doesn't seem to want to connect to anything. I also only have the one omega boot slot, and it works fine, but I would love to get khiCAS and dual boot working.

halcyon hill Sep 16, 2022, 9:47 PM

#

ok so i tried the recovery on the numworks website, but now the screen just flashes on and off regardless of power state

#

it still boots into the bootloader and shows both slots on epsilon 19.5.0

#

not sure where to go from here

zealous orbit Sep 17, 2022, 12:38 AM

#

@halcyon hill 19.5, sounds like you need to downgrade and unlock your bootloader with Pi or whatever it is called

halcyon hill Sep 17, 2022, 12:52 AM

#

Calc doesnt want to connect to anything, just disconnects when i try

zealous orbit Sep 17, 2022, 12:53 AM

#

I suggest making your own, and being patient for better assistance

#

I'm just a fellow user, so I can't do much for you

#

It was a chore getting mine to where it is

halcyon hill Sep 17, 2022, 12:53 AM

#

understandable, i prolly just bricked it :)

zealous orbit Sep 17, 2022, 12:53 AM

#

But in the end, it is a treat to be able to finally have it

zealous orbit Sep 17, 2022, 12:54 AM

#

halcyon hill understandable, i prolly just bricked it :)

Press reset + 6 and see if you can get in recovery mode, and then try to rescue it on the official site

halcyon hill Sep 17, 2022, 12:54 AM

#

thats what originally caused the problem

#

screen just flickers when not in the bootloader

halcyon hill Sep 17, 2022, 12:56 AM

#

zealous orbit I suggest making your own, and being patient for better assistance

what should I make?

zealous orbit Sep 17, 2022, 12:56 AM

#

halcyon hill what should I make?

A "forum post" or whatever it's called in #1019641616652304384

halcyon hill Sep 17, 2022, 12:56 AM

#

ohhh

#

yea

#

thank you

#

so fun fact i had the wrong driver installed and got it into recovery to reinstall omega

#

that seems like a really good workaround for people that have epsilon 19
