I thought it would be useful to have another source for the latest firmware files and DSP updates for the Onkyo receivers other than the AVSForum so here they are.

Onkyo DSP Update Instructions

DSP update for Onkyo TX-SR605

DSP Update for Onkyo TX-SR705/805/875 and TX-NR905

Supposed to fix DTS HD-MA "bomb" / digital garbage issue

Onkyo TX-SR875 Main Firmware Update Instructions

Onkyo TX-SR875 Main Firmware Update Version 1.07

Supposed to improve / fix audio switching delay and lipsync issues.

Onkyo TX-NR905 Main Firmware Update Instructions

Onkyo TX-NR905 Main Firmware Update Version 1.08

Supposed to improve / fix audio switching delay and lipsync issues.

Some cautious notes (and legal stuff):

As always: Read the instructions FIRST.

Update Path: The recommended upgrade path for the "Main" firmware should be:

TX-NR905: if below 1.05 goto 1.05 first, then 1.08.
TX-SR875: if below 1.04 goto 1.04 first, then 1.07.

Note: There is evidence, that some older 875 units with firmware <= 1.01 can't be updated this way. So BEWARE ! The prerequisit is, that the displayed loader version "Main Update" must be at least Ver.1.01/07615L.

Onkyo instructions state, that the upgrade / update needs either 1.05 or 1.04 (model specific) as a starting point. If in doubt, check with your nearest Onkyo dealer.

Check Your existing firmware version:

=> Turn on Your unit, push & hold "Display", press "Standby". Do NOT install if Your current firmware to start with for 905 is below 1.05 or 875 is below 1.04, others (805/705) I 'm not sure. 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 dealer who may be able to help carry out the complete update procedure.

Installation procedures:

The update consists of
...a) DSP Firmware Update
...b) Main Firmware Update

There are two update paths for these updates:

- DSP firmware update: The firmware resides inside a .WAV file (!), which needs to be burned onto an audio CD and played back through a CD/DVD-player connected by an optical link (TOSLINK) to Opt1. There must be a one-to-one copy of the file and it must be transfered unmodified. Most older CD/DVD player will work just fine.

- Main firmware update: The update routine uses a RS232 connection to the rear of the unit. The RS232 cable must be of type straight through (no crossover) with a male and female connector at the end. You need a PC with a COM1 port (default) or a USB => RS232 converter for this, as described elsewhere. The update procedure is been initiated through a supplied setup software, which handles everything.

Hardware Reset:

The AV receiver contains a microcomputer for signal processing
and control functions. In very rare situations, severe interference, noise from an external source, or static electricity may cause it to lockup. In the unlikely
event that this happens, unplug the power cord from the wall outlet, wait at least 5 seconds, and then plug it back in again.

Initialisation ("Clear"):

To reset the AV receiver to its factory defaults, turn it on and, while holding down the [VCR/DVR] button, press the [Standby/On] button. “Clear” will
appear on the display and the AV receiver will enter Standby mode.

Onkyo 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):

1) Turn the unit on.
2) From the front panel- Push and hold "Setup", then Push "Enter".
3) 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:

1) Turn the unit on.
2) From the front panel- Push and hold "Setup", then Push "Return".
3) 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 risk damaging your unit. The update routines are reasonable "fault tolerant". You may revert to an older firmware anytime, if needed, in any case.

The use of these files to carry out any updates is done so entirely at your own risk and responsibility. Should you fail to carry out these updates correctly or successfully and the result is a unit that does not function correctly then you will be charged by your dealer and/or Onkyo for labour and parts required to rectify the problem. If you are in any doubt about carrying out these procedures yourself then contact you local dealer who will be able to assist you in this matter.

Hi crustyloafer,

I haven't got the cable or rs232/ usb adapter yet but I have been reading up about the updates for my Onkyo 905. I believe mine is on 1.05 but will have to check.

My issue is where it states

"Update Path: The recommended upgrade path for the "Main" firmware should be:
TX-NR905: if below 1.05 goto 1.05 first, then 1.08."

and

"Check Your existing firmware version:

=> Turn on Your unit, push & hold "Display", press "Standby". Do NOT install if Your current firmware to start with for 905 is below 1.05 or 875 is below 1.04, others (805/705) I 'm not sure. 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 dealer who may be able to help carry out the complete update procedure."


Then on the main FIRMWARE UPDATE-1 it says

"3. Make sure that the following message appears on Front Panel.
If the version is not “1.01/07615L,” DO NOT carry out upgrade with this tool.
The upgrade will cause the unit to no longer operate properly until FW is correctly reloaded."

This seems to be a contradiction as one statement says do not carry out update if the version is not Ver.1.01/07615L and another says it needs to be at least 1.05

I would appreciate it if you would clear this up,

thanks,

Graham

When it says a CD player connected by optical, can I use my PS3 for this?? I only ask as it is the only thing I have which plays CDs and connects via optical!

Will do this before I plumb in the Onk 705 to its home in my wall!!

This first step is to check exactly what version of the main software is running on the unit already. It needs to be 1.05 or newer to be able to apply this latest 1.08 update to the 905.

This step which is part of the actual upgrade instructions is actually chacking something slightly different to previously. This is making sure that the firmware upgrade utility within the receiver is version '1.01/07615L'. The firmware upgrade utility is a different piece of software to the actual main firmware in the machine.

To sum it up, the main firmware needs to be 1.05 or newer on a TX-NR905 and 1.04 or newer on a TX-SR875 in order to be able to apply this latest update. In addition to this, the firmware update utility software within the unit must be version '1.01/07615L' in order for it to function correctly.

I have successfully applied these DSP and firmware update to my demonstration TX-SR605 and TX-SR875 with no issues whatsoever. I will apply them to my new TX-NR905 when it arrives if it does not already have them installed.

I have not tried it with a PS3 but can't see any reason why it wouldn't work. I used a Marantz CD6002 to apply the DSP update to my demonstration TX-SR605 and TX-SR785 this afternoon.

yes you can reportedly use a PS3

2) Sound settings -> Digital optical out: 44.1kHz & 48kHz (i know someone earlier had posted to tick 44.1 only but both my 44.1kHz and 48kHz were greyed out and could not be unticked for some reason)

Thanks for this thread, but where to find the main 1.05 firmware for the TX-SR705 ?
Links given there are only for the DSP if I understand clearly.
Mine says V1,01, so I can't try DSP update. I'm interested in the main 1.05 to correct the HDMI handshake problem.

Firstly, the unit does not require to be at firmware version 1.05 in order to be able to apply the DSP update. It is only a requiremement to already be at firmware version 1.04 or 1.05 on the 875 and 905 in order to be able to upgrade to the newer 1.07 and 1.08 updates available for those machines.

I do not currrently have a copy of the main firmware version 1.05 for the 705 at the moment. I will PM you with details of where you can request a copy. Once you get it if you could forward a copy of it to me I will host it and it it to this thread for others.

The 'Target Unit' is the unit you are appying the update to, ie your 875. The enter button is underneath the flip down front panel to the left of the Setup mic socket, it is the one markeed' Enter'

Could you please forward me a copy of that file so that I can host it and add to to the list of available downloads in this thread. You can send it to (crustyloafer@hotmail.com)

[sunnyhd]

Hi guys

I downloaded the firmware but I can’t seem to make it work. i had this problem while ago with bd30 firmwere as well, is anyone out there would be kind enough to send me the disk with 1.05 and 1.08 as I haven’t done anything to my 905 since I brought it last year. I am not even sure what kind of firmware it has and needs. I defiantly need to fix dts mt hd bomb. Which I experienced last night while watching AVP.R….Man! that was scary I thought I had blown my pb13.
I would love to fix the delay from sky as well which is really annoying. so please help


Thanks in advance for anyone willing to help
James

That should do the job nicely.

thanks for quick reply . also is it worth doing that dsp update as it is only for ps3 timebomb

[DJ Ovengloves]

It's actually for the DTS-HD MA sound bomb when you bitstream DTS-HD MA to the amp.

Since the noise the bomb makes could potentially cause damage to your equipment I would most certainly do this update.

[Crustyloafer]

It is worht doing anyway for peace of mind. It does not happen when using a PS3 at all, only when sending a raw bitstream of a DTS-MA soundtrack for the receiver to decode. As the PS3 does all the decoding internally before outputting the audio to the receiver it is not affcted by this bug.

ah right so it will happen when i get the Panasonic DMP-BD30 so better do it then. i emailed onkyo yesterday about the dsp update and still got no email dam stupid that due to the fact that time bomb does sound bad from what posts i have seen

[namuk]

also were is the Tone “ +“ button ? when i do the dsp update? and i take it Optical Input 1 is the game input on back of amp? also does it matter which i do first firmware then dsp or other way about?

i checked me dsp 1-3 and too the pdf posted it seems on my 875 the dsp1 only needs updating and i have the hdmi 1.1 version also do i still need to update dsp?

dsp1 is 07601a

[Crustyloafer]

The Tone + button is the one directly below the Tone button.

Yes, that is correct, that is why it is also labelled as 'IN 1' meaning it is Optical Input 1.

I don't believe it matters.

I would still advise applying the update to make sure that all the DSPs are up to date.

On another subject Neil, you sent me a PM earlier and I tried to reply but your account is not setup to receive PMs. Don't you think it would be a good idea to make sure you can receive replies before sending PMs to other people. I was most annoyed at having spent the time to reply to your message only to have the system tell me that I could not send it to you.

thanks for that . the pm should be setup ??? i will sort this out it says it is on try it now mate

Any chance someone has the firmware files to take my 705 from 1.04 to 1.06 ??

[Taomyn]

Managed to do the Main firmware update on my 875 from 1.04 to 1.07 without a hitch. Used a WinXP laptop connected via my trusty USB-to-COM lead straight into the back of the 875 (no extra lead required). For those needing to use a USB cable in my experience those based on the Prolific chipset are the most stable and compatible. Did my Samsung F71 LCD with the same one.

However, the DSP upgrade isn't going so well. I've tried using my Samsung DVD-HD860, my Xbox 360 and an old Philips DVD-R player all with optical and the unit simply sits at the "S/PDIFUpdate..." point and that's it. I switch off, it clears and I'm back to factory defaults.

I've confirmed that the 875 is receiving audio from the correct optical-in by playing an audio CD, tried 2 different optical cables and burnt the audio CD 3 times. I'm out of ideas.

Tomorrow I will ask friends if they have an old CD with optical I can borrow - this is a crazy way to update. Why didn't they use the RS-232 like with the Main firmware.

In the meantime, I'm open to any suggestions,

TIA.

on the
DVD-HD860 did you set it to pcm out at 44 khz i.e cd format?

I changed all the Bitstream to PCM but didn't see a setting for 44khz. I'll take a look again in the morning in case I missed it and post back.

it is above bitstream . pcm output . set it to lowest

Nope, all I have is:

Digital Out: PCM
MPEG-2 Digital Out: PCM
DTS: Off
Dynamic Compression: Off
PCM Down Sampling: Off

I've tried various combinations of the last 3 with no success
