Th pins 18, 19, 20, 21, 22, 23, 24 e 25 of the port LPT must be shunted between themselves, like commercial jtags has. Now, The cience of the thing is doing the connect and turn on the box at the same time. With the tests done I've understood better how it works great: The secret is in 1º do connect to the program and then turn on the clone, but with a certain delay. This delay depends on the speed of your CPU, the faster CPU's, minor the time/delay (between 0 e 1 seconds). Change the priority of the program jtag_windows.exe on the task manager for the real time which must turn more real the delay itself, once the program will give maximum priority of the use of the CPU. About the timming, if it shows you only "ERROR:register test failded" then the jtag is ok, but you have turned on the box sooner then expected, if it shows you the 4 times "ERROR: communication with LPT/JTAG", then you must turn on the box sooner, or the jtag isn't ok. Remmember that you must connect the box always after making connect on the program. After you must warp/straight the pins on the adaptor switch of the box, so it fits faster on the electric switch. By end, you must use an electric switch easy to fit, I have used one triple (from the bad ones), but I had to dismount it and press their electric pins to don't make bad contact. When doing "write" the program sends immediately the boot, that is the file "blimg". The file present in this attachment is the boot of a DM500 and tunner ALPS of CRC-32 9055B110, once again thanks Matrix10, because I've tested a boot that were supposed to be for the DM500 and ALPS and it didn't worked, and this one in the attachment is guaranteed it works. after sending the boot of 128KB by Jtag, you can turn on the box with dreamup and by rs232 send an image

how many posts before i can download?

I managed to JTAG my dreambox with Jtagdm500 (Dostool)
very good!!!
I also can load images with dream upload with succes. The onley problem is that Gemini will not boot nothing happens after I restart the box

Does anyone has experience with this ....or should I JTAG again

thanks in advance

[dr_grebber]

Congratz with this milestone M8, was this problem related to the wrong MAC address? (clone etc)
Speak you later,

I just manage to solve my problem:

I juste restarted the procedure from the beginning (jtag)

At first the program (Dosversion) was not recognizing the flash. But the trick was to powerup the dreambox and after some sec start the alps2.bat

this worked for me!!!!!!

Now my box is genuine ....Ye baby!!!!

Hello i am new here and i would like to thank you in advance for all the good advices...i have a problem with my dm600 and i believe the only solution is jtag...thanks!!!

[permoulos]

Hi champs, I have flashed my DB 500 with image Gemini 4.6, it worked fine for few hours and suddenly said/ "clone Dreambox detected, contact your dealer Adieu" now nothing happens not even the the red diode of power. Some one told me that I have to short circuit some where inside the box all I need is a wire and a soldering iron.
Is this called jtag?
Does some one know how?

[botoseli]

i will tray today, thanks

[lampadinac]
