Hi guys

my d500 was working fine but i couldn't connect the box with serial cable, so i have flashed the box with ftp and it was working fine .

I ahve flashed the box again with diffrent img with ftp and now the box come on and after displaying bootup picturte tv screen goes black nothing work.

normaly my other box comes back alive with serial cable flash but this one doesnt connect with cable so i can't flash another img.

box comes on but after few second nothing comes on.

So do i need to use Jtag ?

Hi All,
I have probelm with 500c to make Jtag for that,
1. Can someone write a ling to download the files that I need after connect the PC to dreambox as described here.
2. If to make jtag for 500c and 500s are the same?
thanks,
doki

FOR DM500S, if your intel flash is JS28F640, use the dos program. Only for DM500S, sat tuner because the bootloader is for sat tuner. For TE28F640 flash chip, you can only use the jtag window program, load the right bootloader for your tuner, ALPS and Philips is different. Change the 000000000 to something like 00:09:34:??:??:??.

For DM500C, CABLE bootloader is diff from SAT. only 1 file for the tuners.

Trying to Jtag my DM500S with jtagdm500.exe but after flash erase nothing is displaying in the screen (no upload etc.) Any ideas???

After JTAG you must upload an image with DreamUp ...
With JTAG you did just upload the bootloader ... I think ...
.. fighting with some similar problems ...

[mikulas7]

So ... here is my story :

First of all I JTAG-ed it correctly and flashed up with windows progy ... but nothing happend .. so I flashed it a few more times ...

Then I found the DOS progy ... but did not know is it Alps or Philips I have ...
So I flashed with both a few times .... ( I think I have Alps .. after I read a few hundred site's about it .... )

It's flashed now in DOS/Alps ... but still cant reach it with RS-232 DreamUp ...

Any ideas ?

Thanks for the reply bro

Even if i use Jtag, I don't think i will beable to upload the image through Dreamup ? bcz my serial cable connection doesn't work on this box...I use to upload image through FTP.

Is there any way to falsh the image through Jtag?

I went to upgrade mine, time to restart, do not start anymore. By connecting the DM500S at source, the Green LED is lit directly. I tried with the serial cable, but does not connect dreamup. Anyone know how can I solve this?

[mtv1]

try an older version of dreamup the one on my siggy works on the 500s keep trying and good luck
