[Solved] Downgrade CX CAS from 4.3 to 4.2

[hoemknoebi]

Hello

I unfortunately upgreaded my calculator to the os 4.3 and i first realised that ndless isn't compatible with this os as i already done it. so my question is there anyway to downgread to the system 4.2.

Hi.

If you didn't install nBoot before upgrading to 4.3, then there is currently no way for you to downgrade back to 4.2.

Hi,

Any news on downgrade from 4.3 to lower SO version?
Or ndless suitable for 4.3?

Thanks,

Actually, there is a way to downgrade it to 4.2.
You need to be careful though so don't fu it up !
1. Pick a hammer
2. Hit the area behind your calc where the battery is.
3. Then hit really hard on button +.
4. Hit the usb connector.
5. Simply transfer your old firmware to your calc and it will work !

Not as far as I know...

I also accidentally upgraded to 4.3 while reinstalling my OS...
Is there an estimated time as to when ndless 4.3 will come out? Or can I downgrade?
I'm on Revision X by the way.
So sad.
Thanks

It's already written in this thread: no.
And no news about a potential Ndless 4.3 either.

[klamarlit420]

Hmm so is there a higher chance of an ndless 4.3 coming out or no?

[critor]

Impossible to say.

No significant progress on this as far as I know.
So not soon, but it doesn't mean never. It can take weeks, months, years...
