you would have to buy a null modem cable and a usb to serial adaptor . the problem is that usb adaptors require a driver (that's a bit of software basicly to help the computer see that a box is connected to it) and the drivers seem to be incompatable with vista and even xp , atleast in my experience and ive been doing this a while . if your box is a dm500s you can use the method I posted above (the root.cramfs method) to flash your box , if its a dm7020 or a dm800 you can flash it via your web browser or you could get the use of an old desktop computer to flash it via null modem cable.

Just bought a null modem cable f/f but my laptop dont have the port...how to connect?

most laptops don't have the 9 pin connection . you have two options
1/ buy a usb to serial adaptor (this connects to the null modem cable )
2/ get the use of an old desktop computer (as this will have the 9 pin connection)

the problem with usb to serial adaptors is that they require a driver to work , a driver basicly is a bit of software that you download or which comes on a disk and when installed helps the computer to see that its got a device connected to it. the problem is that windows vista is largely incompatable with these drivers , ive never gotten a driver to work on a vista laptop and I only had a driver working on an older windows xp laptop , ive never managed to get a driver to work on newer xp laptops , so chances are you will have a serious problem here . this is why I say get the use of a desktop computer , that way you wont need any drivers .

if your box is working and not bricked (stuck on the green light etc) then depending on your box model you could have an alternative way to flash the box . a dm500s can be flashed using dream control center and the root.cramfs method , a dm800 can be flashed via web browser .

Hi all I am getting this msg when I connect to the PC...it says unable to open com port

**piopat** · 28th October, 2013, 04:24 AM

there doesn't seem to be any com port displayed in the picture you posted (where it says serial port ) usually there it says com1 by default , and when you click on the little arrow you can select com2 etc . nothing is displayed in the picture above , so that's why its not opening a com port , but why this error is occurring I don't know . what version of dreambox have you got ? , I know some versions of dreamup say they are universal but they are not . newer boxes like a dm500hd or dm800se would need the latest version of dream up , a dm500s will work with older versions . id try a different version of dreamup and see if the same error occurs. only other thing I can think of is that the com port on your computer is not active .

Hi I tried again and I can select com 1 and com 3 only but which one shld I select? Mine is a 500c

**piopat** · 28th October, 2013, 03:41 PM

usually you would start with com 1 , so try com1 and see if it works , if it doesn't try the other com .

i am stuck at this screen...how to proceed? i cant click on flash..i just cannot proceed on to the next step

what version of dreambox have you got ? dreamup is not really universal to all boxes in my experience so if you have a version that's best suited to your box its better . so if you let us know what version of dreambox you have we can better advise you .

Mine is DM 500C. I have tried dreamup 1.3.2.1 but I am still stuck at the same page...how do I proceed? Is it really frustrating
