Software/Hardware required:
- Nero Burning Rom (provided with your burner) version 6.x
- The firmware at the version you have decided to install (download it here)
  - file C1A1F2MM.AKI for the PVR-800
  - file D1A1F2MM.AKI for the PVR-820
- 1 recent CDRW not worn (a CDR is recommended)

Description:
Generally speaking, the firmware upgrade allows to increase the capacities of your player to read more audio and video formats, to correct problems of reading or to update the OSD (visual interface of navigation).
The used process is a replacement of the software contained on the flash memory or in certain cases the replacement of a subpart of the existing software even of an update of one or several existing software (called a "patch").
In our case, it is a total replacement of the various integrated software.

Notes:

• do not copy the firmware to the hard disk of the PVR! Even if it is a different way to update the PVR, it is also the best way of missing the update. Thus abstain from copying this file in any folders of the disc.
• Check the list of improvements in the firmware download page
• this update contains all the previous improvements, so you do not need to apply all the updates, only one is enough.
• This guide is based on the use of Nero version 6.x but Nero 5.x, Easy CDCreator, Toast (for Mac) or any other burning software that can burn using the ISO 9660 mode is enough to complete the task.
• Certain persons do not manage to update their firmware, but in the majority of the cases it is because they did not follow literally this kind of guide. I thus ask you to read indeed and to read again all the steps before writing me or posting a message in a forum ;o) There are no reasons to fail the upgrade (except problems with the player)! If you don't understand my english, then come in forum to get more details!!

Guide:

1st step: burning the firmware on a CDRW (based on Nero 6.x)

1. Install "Nero Burning Rom" version 6.x (or any other burning software) if it is not already done

 
2. Download the firmware you want to install
   - if you get it from this site you should obtain a ZIP file format: unzip the content to get the real firmware
   Important notes:
   - the firmware file name MUST BE C1A1F2MM.AKI for PVR-800 or D1A1F2MM.AKI for PVR-820
   - its size MUST BE sharply the same as the one noticed of on the firmware download page
   If these 2 conditions are not gathered, then try again to download it or come to ask us in the discussion forum!

 
3. Launch Nero

 
4. Insert the recent (not damaged) CDRW (or CDR) in your burner

Wait for some seconds to let Nero resumes.
 
5. If you get the "Nero Express" mode, then switch to "Nero" mode clicking on "Nero" button!
    
6. In the "New Compilation" pannel:

- top left part, choose "CD" in the drop-down list
- bottom left part, choose "CD-ROM (ISO)" in the icon list
 
In tabs, choose following options:
"Multisession" tab
- "No Multisession" must be selected
"ISO" tab
- File name length: "Max of 11 = 8 +3 chars (ISO level 1)"
- Format: "Mode 1"
- Character set: "ISO 9660"
- "Joliet": this option should be unchecked (to be safe)
"Burn" tab
- "Write" must be checked
- "Finalize CD" MUST BE checked!!
- Write Speed: "please do not select the maximum speed but rather an other less fast if possible"!
- Write Method: "Disk-at-once"
 
7. Click on button "New"

The project wizard closes and main Nero window appears.
 
8. In the right window, choose the file corresponding to firmware (ex: "C1A1F2MM.AKI") and drag&drop it in the window most to the left.
   Obviously you have to select and open the good directory "to see" the file before drag&drop it.
    
9. Choose the menu "Recorder\Burn Compilation..."

A new window "Burn compilation" opens.
 
Please check again in the "Burn" tab if the following options are checked:
- "Write" must be checked
- "Finalize CD" must be checked!!
 
10. Launch burning using the "Burn" button

The file is going to be burned on support, please wait until the end of the operation and go to next step.
 
11. When the burning is launched you should check the option "Verify written data"

If an error happens during burning or post checking, then throw your support and try again with a new one!

2ns step: upgrade firmware

VERY IMPORTANT :
- do not switch off the player during upgrade process
- do not upgrade by stormy weather or use uninterruptible power supply
- do all the process WITHOUT the remote control: all can and must be done by the buttons on player itself!
- if the upgrade failed you could be forced to return the player to Sigmatek or your retailer, so be careful!
 
1. Switch off the Sigmatek player using button in facade

 
2. Switch it on

 
3. Open the tray using "Open/Close" button

On first try, the tray won't open, it's normal, then pust it a second time.
 
4. Put your CDR/CDRW containing the firmware and close the tray using "Open/Close"

- "LOAD" is displayed on LED pannel
- The upgrade is now launched and you could see on TV screen the following messages: "READING / ERASE / WRITE / BANK3" (several times) and then "DONE"
This process lasts between 30 seconds and 1 minute.
- At the end, the tray automatically opens: DO NOT TOUCH ANYTHING!
- few secondes later the PVR-800/PVR-820 switches to stand-by mode, it's normal!
 
5. IMPORTANT: remove the CD from tray right now!

Then switch your PVR on!
 
6. To be safe, reset all parameters to default values (menu "Setup\Preferences\Defaults"), then set yours.


CONGRATULATIONS, you have probably upgraded your player successfully!

Have a good upgrade
