I found these late "
easter eggs"
DSP Update Onkyo 605DSP Update Onkyo & Integra 705 / 805 / 875 / 905 / 8.8 / 9.8 / 885
------
Main Update Onkyo & Integra 905 / 8.8 ONLY (1.08)Main Update Onkyo & Integra 875 / 9.8 / 885 ONLY (1.07)
Supposed to fix DTS HD-MA "bomb" / digital garbage issue.
Supposed to improve / fix audio switching delay and lipsync issues.
See enclosed
attachments (PDF) below for installation instructions (same as in archives).
Previous "public" releases from joerods distribution:
Main Update Onkyo & Integra 905 / 8.8 ONLY (1.05)Main Update Onkyo & Integra 875 / 9.8 / 885 ONLY (1.05)Main Update Onkyo & Integra 875 / 9.8 / 885 ONLY (1.04)
Please ask joerod, if there are any questions for those.
Note: These are "official" release version files.
These files are been employed by Onkyo service points and handed out elsewhere by Onkyo to customers (free of charge).
They are identical to those versions preinstalled on factory fresh units (look
HERE)
Version numbers are model specific, thus a 1.07 firmware for the 875/9.8/885 is as current as 1.08 for the 905/8.8.
This update will upgrade "Main" and "DSP1" (and DSP2 / DSP3, if not current already).

Some cautious notes (and legal stuff):
Do NOT contact me, if those links don't work (anymore).
I don't take responsibility for them or their contents, I am just a scout

As always:
Read the instructions
FIRST.
Update Path: The recommended upgrade path should be:
905/8.8: if below 1.05 goto 1.05 first, then 1.08.
875/9.8/885: if below 1.04 goto 1.04 first, then 1.07.
The prerequisit is, that the displayed loader version "Main Update" must be at least
Ver.1.01/07615L
If not. I don't know...
Note: Several users have indicated, that a direct update without intermediate steps from i.e. 1.02 to 1.08 did work for them.
Onkyo instructions states, that the upgrade / update needs either 1.05 or 1.04 (model specific) as a starting point.
Check Your
existing firmware version:
=> Turn on Your unit, push & hold "Display" and press "Standby"
Do
NOT install if Your current firmware to start with for 905 / 8.8 is below 1.05 or 875 / 9.8 / 885 is below 1.04, others (805/705) I don't know !!!
If You got an earlier version to start with, there might be additional steps to be taken (DSP:hardware modification + HDMI+NET:additional firmware) !
If this is the case, and You need them, contact Your nearest ONKYO service point for the complete update procedure.
I told You so...
It is suggested, that those updates are universal for the Western hemisphere.
I can't verify this ... anyway, version IDs are identical.
If in doubt, check with Your nearest Onkyo service point.

Note: Just to make sure, "joerod" and numerous others have tested them and they work just fine.
Place a PM to joerod if You want this update sent to You by e-mail instead of downloading it Yourself.
Beware: Anyone with an "
Audyssey Pro" installation: The update routine of the "DSP" firmware is at fault,
deleting all Your (costly) "Audyssey Pro" settings. Be prepared therefore, to call in the Audyssey installer again afterwards !
This holds true for the "normal" Audyssey parameters too.
Your personal settings will be erradicated running the update routine of the "DSP".
... and You will not have the opportunity to save anything.
A
hardware reset is recommended strongly in any case to get the new firmware properly initialized.
Audyssey should also be rerun after the update, because some things might have changed.
Note: Audyssey has stated in the meantime, that nothing has changed in this firmware release with respect to the Audyssey implementation (but one never knows...Onkyo might have done something)

Onkyo / Integra has indicated, that the following method saves settings "permanently" (not on the "DSP" update).
Note: It has been reported, that saving
Your settings,
will not survive the DSP firmware update procedure !
Be prepared to redo everything. So write down Your setting
before updating the unit !
1) TO STORE SETTINGS (must be done first, otherwise the recall will not have anything to recall):
Turn the unit on.
From the front panel- Push and hold "Setup", then Push "Enter".
The unit will display "Setup Store?", push "Enter" again and the unit will display "Setup Storing", then it will display "Complete" and thus the procedure is complete.
2) TO RECALL SETTINGS:
Turn the unit on.
From the front panel- Push and hold "Setup", then Push "Return".
The unit will display "Setup Recall?", push "Return" again and the unit will display "Setup Recalling", then it will display "Complete" and thus the procedure is complete.
Remember: If You are unsure, what all this means or what You are doing ...
Don't do it !
Get professional advice, before You brick Your unit.
No guarantees whatsoever !
I do not suggest or advice anyone, to install or use it.
I am not connected with Onkyo in any way.
Don't hold me (or Onkyo/Integra or anyone else) responsible for anything You are doing.
You are on Your own, as always ...

Take care... and have fun.
