Hi
Nice post eFriskey, I was sure I had read something about this problem before, must have been from you. This should now help sort out a few with corruped bootloader / wrong 'blimg' file problems.

Desperete DM 500-s

Hello, I have made JTAG cable, I know I have alps tuner, I now how to "flash" using jtag_windows.exe and JtagDm500.exe, I can flash it, but nothing happens. I tried so hard, I have lost my hope to restore my dreambox (Chinese clone, looks like real DreamBox). So, I have some questions:
1. Is there a posibility to flash with wrong wires and making wrong result in my dreambox?
2. When reading CA (using JtagDm500.exe), what must be the results? (I know that not ff ff ff...) I have misterious 0601832000690000000006ff04 (I Think its wrong).
3. Should I have working switch to turn on and turn off dreambox? (because mine ins't working since manufacturing. I always used remote and just plug off the cable. Is there a workaround? (not buying switch, but making contacts))
4. When it's flashed, I try to use DreamUp (I have Zero Modem Cable, also seccond one RS232) - nothing happens, it doesn't detect my box at all. (So I'm going back to bootloader... because I think there is fault. )
5. I'm using windows Xp SP3.
6. BIOS settings I have changed to EPP + that second one (cant remember).
7. AMD Athlon x2
8. Somewhere I have read about jumper (??? Does I actually need it?)

And excuse me for my language.
Any suggestions?

@eFriskey
switch to dos version body.
in my first experience I've got same problem .tried many different blimag & mac generator from different places .after 10 days the result was nothing. so many times loading blimg to dream without any result.
after that I moved to dos to jtag my dream and it works great.
here is my procedure :
1)Click on 1info.bat to determine 2 thing A) jtag connections B) Tuner type



2)Close dos window and click on 2alps.bat to start loading boot loader. (in my case it was Alps tuner. if you have philips tuner click on 3philips.bat!)



3)after all close dos window , connect your null modem cable and start flashing your dreambox with dreamup.

Hi guys
I am struggling with my original DM500 for some while, it have TE28F640 INTEL flash onbord, and ALPS tuner, I've used windows flash program with 3 different bootloaders, and no results. I have no green led, strange is that when I doing soft download dreamup is showing BOXtype DM56xx??!! I still can download software into box succesfully, but nothing else blank screen. Could somebody show me which BLING file I should to use. It is an original DM500S box bought 3 years ago. Thanks

its just about jtag. one of my costumers got same problem on db 500s.
Regards.

There's now a guide, pictures and all the tools you need to JTAG your DM500.

You will need these tools if your clone has been zapped by the Gemini 4.3.1 image.

Untested by myself, don't use Gemini .

Njoy!
