I have a bad boot file that was corupted trying to loat the 4.06 nano upgrade and need to update thru the RS 232 port. I have the 7.08 LDR file and a null modem cable hooked to the computer and the reciever. What do i do now? When I hard boot the reciever nothing happens. How do I get the file loaded onto the reciever?

Thanks for your help

Boot loader with RS232

* If “100” displays on the front panel, boot loader with RS232 is feasible. “100” may not come on at first time, try a couple of times. If not, need to send your box for repair.*

1. Turn the box off from the back.
2. Connect your box and computer with RS232.
A. Null Modem Cable is Required for ALL CNX Products.
3. Go to your computer.
4. Close all the applications completely or restart the computer.
5. Open loader file.
6. Click Connection and select Connect.
7. Select your port according to your computer and click Ok
A. Check COM# open ok on the bottom.
8. Click Set-top Box and select Firmware Upgrade.
9. Click Select and look for “.ldr”.
A. If you don’t see it, type in “*” in the file name and press (only) Enter on key board.
10. Double click on “.ldr” file.
11. Click Upgrade
12. Turn your box back ON. “100” should be display on front panel and should see Debug Print loading “ex_send”.
A. If you don’t see “100” on front pane, turn your box off and on till you see it.
13. Wait 5 minutes.
14. “ex_send” should’ve been stop.
A. Indication of finish loading: widen the loader window box and should see “Branding to loaded code image’s entry”
15. Click Close to close the loader window box.
16. Close Mvision window box.
A. Before you reboot you box, Mvision window box MUST be closed.
17. Turn your box off and on from the back.
18. Now you have TV again. |(^O^)/

If you have XP and are not sure which serial port your PC is using, download and install this little utility:

Well thanks for the help, it looks like this one will be going back for repair. The front panel stays on 0 and a red light.

See if you can load the factory file on the unit, BEFORE you send it anywhere.

I've tried every thing I can think of and can't get to a place where it can be loaded

Note that you cannot load an upgrade file using the recovery procedure. You cannot even load a factory file. The file must have the .ldr extension to load via the loader.
