Flashing A780 using XP

Hi

Can anyone confirm that you don't need to change the
com port settings baud rate ( bits per second ) from 9600 to 115200
if you are using XP and just a null modem cable to flash
the box.

Do you only need to change the settings in device manager
when you are using a USB convertor lead ?

Thanks for any help

the only setting i changed was the com port number on the downloader com 1-4,never used the usb adapter but it may need drivers or the port may be switched off.
 
Thanks, thats what I thought,

You generally need a driver for USB connector setup
and also need to change the baud rate to 115200, no matter what windows package,

Must be something to do with the amount of data
the USB lead can handle.

but used windows 7 and USB adaptor to flash mine
had less luck than Ted !!!!
 
Hi Ted,
My name is jodav and I will try to help you with your Kryptview :)

I could talk ou through using a USB to serial cable with a NULL cable but there are so many differentials with different comps\BIOS\operating systems that it can be hard to communicate effectively in good time, so I will not bother. Take the below advice which fingers crossed should be OK.

My advice is use a computer that has the old NINE pin MALE serial adapter so all you need to use is the Null modem cable, this eliminates the need for a USB to serial cable connected to the NULL modem cable. If you do not have a desktop\laptop with this type of old connector on I suggest find a friend who does (this should be the only hard part with the whole process). The older the comp the more chance it has this connector.

Once an older comp is found, forget about doing anything in device manager etc (no need to set COMM ports, BAUD rate or anything), you will be able to flash your Kryptview as per the tutorial with no problems.

It is MOST important you have the NULL modem cable as opposed to a RS232 cable. They look visually exactly the same but are wired differently inside. So ensure you are positive you are using a NULL modem cable.

Very Important things.

1 Find an old comp with 9pin serial connector.
2 Ensure you are using a NULL modem cable.
3 Serial connection is not hot plugable, so reboot laptop once you have plugged the NULL cable in.
5 Follow this tutorial closely (take your time) and you should have no problem.
4 The box only needs to be flashed once manualy, after that you need to reflash over the Internet with the boxes LAN connection, so you will not need to find an older computer for future flashes. More on that if you need it once you have your manual flash done.

Good Luck Ted,
jodav :)
