You need to keep the init file in /etc to reset your MAC address on each restart; the other methods discussed may be more permanent but I've not tested any of the MAC address methods.

Do i need to change the Attributes of the init file? I note on creation that it is 644 but the original init file is 755, i tried to change the attributes in properties but this still does not seem to work on reboot.....A B C guide for me? I did not understand the chinese reply, the english translation was not good.......Wo Ting Bu Dong...?

If you enable vcard in your profile other members can send you email - this may help if you need to speak not in English.

I haven't tested the init file/ MAC address solutions but it should be 755 permissions.

Are you Chinese ?

Are you Chinese ?

No, I'm English living in China. Hense my Chinese is not very good.

Yes i changed the attributes to 775 and now today it seems to work and the MAC address is changed on boot up.

Thanx for your help.

On LPT connector you short connect pins 18 to 25, and there goes wire for ground.
when you click connect on program simultaniously put the power to box.

Thanks all,
I have Question. Is there any way to connect the cable to Dreambox500 without doing solder the cable to the dreambox500 board. I creat the cable with LPT connector but my question for the other end. Imagine I have 100 of dreambox, It will take alot of time to connect them.

Any answer please?

Thanks

Thank you very much for the usefull information in this thread.

Just made a jtag cable as described connected at first time and uploaded the boot image found linked in this thread, all seems ok.

FYI. I did not know that i had a clone, checked all the information from dream multimedia to detect it and seemed genuine. Howerver i noticed one little difference after it died. there is a yellow chip onboard the mcb that is black on the original, thats the only difference i have found.

Hello ,

The only that came up about is to create a jtag with a flat cable connector at the other end ( from a old pc or electronics parts store ) .

Then add the jumper pins into connector holes where they are needed. Now you have to attach it on pcb . You need only a trick to hold the connector stable . A metal plate or clip you will find out .

I hope that helps .

Hello ,
Concerning the time bomb , it trace the hardware via MAC address .
Even if you have an original box with modified MAC , your DMbox is killed
too .

The reason that we create this friendly ( i hope ) guide is to reverse back
this action which destroy our dmboxes no matter what , in purpose .

Target reached i believe !!!

On LPT connector you short connect pins 18 to 25, and there goes wire for ground.
when you click connect on program simultaniously put the power to box.

so you connect 18 and 25 of 18 to 25,,i have seen tutorials where they are all connected but the picture in the post above has just the two connected,i am c
confused
