Version 2 OS - still have a question

karmathanever · Post by **karmathanever** » Sat Jul 29, 2017 1:20 pm

I am still not understanding why there are 2 different sets of update files - UPD and PKG.
What is different? What does this relate to?

Also - does anyone believe that there has been any changes to the physical keybeds since it was first released?
E.g. a shorter key-fall on the PA4X-61?

Cheers

Pete

Hello!
Well both pkg and upd contain the same files inside.
Thing is that pkg got opened public and people started modding the os.
Except from the mods that work ok, most of them don't really know what they are doing and as a result they are bricking their systems (causing damage to korg from having to repair keyboards in warranty).
So korg decided after some production runs (when the problem became huge) to change the file to upd and also change the authentication of the file to a custom algorithm so to stop people from modding their machines..
Pkg can be installed on older pa4x while the newer ones doesn't accept it and upd is the only way to update the instrument..!

Hi musiccankill,

I didn't know such a thing existed (older Pa4X and newer Pa4x).
I am really confused.
That's why I didn't yet update to v.2 and am still at version 1.2.4.
Could you please explain what is the difference between both and how can I know if my Pa4X is older or newer?

Thanks

It's exactly as explained by musiccankillbutitdoesnot

, contents are exactly the same but in different packages ,
like for example between Winzip & WinRar !
It has been mentioned many times in the past , UPD format has nothing to do with V1.24 or V.2 , it exists since last year
with older OS , UPD prerequisites have been injected in newer Pa4X Bios and the way to find out what format is required
for your model is explained in Korg website update instructions where you enter in pa4X update mode and read there what
format will be required for updating !
Also the fact that also first production line of Pa4X can accept UDP format , clearly declares the existence of UPD format for
more than 2 years !

Hope this helps

Thanks - I understand the content being the same but...
...do we actually have two "types" of PA4X still or will they all read UPD in the future since V2.

My colleague just bought a brand new PA4X-61 (latest shipment) and it needed UPD files.
Mine uses PKG (older keyboard) so that makes sense now....

@BR
As is said here, there is no difference in the update itself.
If you are in doubt, download all the files (UPD and PKG) and put them all on the USB - your PA4X will only detect what it needs so you will either see the UPD files or PKG files when you are asked to select and install.

Cheers

Pete

Pete I think that I was clear ... this is a hardware change (edited Bios) in newer motherboards , nothing to do with any
OS version and Yes ... in the future all new factory PaSeries will read exclusively UPD files for the reason that was said !

Thanks Antony - sorry - I didn't read your post properly

The Bios update is probably a software one.. altough not a user accessible one.. we have been able to software edit our bios for ages on our PC's.

But its definately there.

We both know what I mean !

Many hardware parts in any electronic device that uses micro controllers require programming that is actually software based ,
but mostly considered as hardware when code injection is not possible from a freely distributed utility (for protection reasons)
or OS update in current case !

In the USA we usually call it firmware. Not to get in an argument, thank you for the information. We appreciate the explanation. But I guessing that the BIOS update is the only change between the old and new motherboards?

The app (OPOS) that is running on ANY pa4x (either pkg or upd) is exactly the same.
What has been changed is the app in a hidden partition of the eMMC disk that is used to load the update packages (either pkg or upd).
There is no bios change or any hardware change.It is just an app (like the windows installer) that now doesn't accept the older pkg format.
That has been made only for security reasons as i stated in my first reply here!
To check which version your 4x is you just have to run the update app by pressing INTRO-1 and powering the 4x on.After the calibration screen , it ll say which version it needs!

Thank you for the clarification.

@ mstodola & musiccankill,
Thanks for the explanation and clarification.

AntonySharmman · Post by **AntonySharmman** » Sun Jul 30, 2017 7:58 pm

Yes it's indeed an app in system files partition , but in newer Pa4X this "app" has been changed by factory default
and doesn't accept PKG files as an update format anymore !

so nothing to do with OS v.2 update itself !
Sorry guys but some things can't be told to end users , so I have to use terms as "bios" as an epidermic explanation
for some functions of sys Kernel that concerns you , that's all ... I hope to get what I mean !

Thank you Anthony for helping us to understand.
