DM600 problems restoring dm600pvr with backup.img

[loncell]

im trying to restore my dm600pvr using a working backup image i made a few weeks ago.i've been trying to follow a tutorial by using telnet to communicate to the box :-
"dm600pvr login: root"
(i then leave the password blank)

this is the only tutorial i could find for a 7000 and a 500:-

Telnet into the Dreambox as described above.
Type in the following 2 lines:
cd /var/tmp [enter]
eraseall /dev/mtd/3 && cp backup.img /dev/mtd/3 [enter] (where backup.img is the name of your image file)
Wait for erase to complete and the prompt to return (be patient), then type:
reboot [enter]

the problem is

cd /var/tmp

as a command is fine but

eraseall /dev/mtd/3 && cp backup.img /dev/mtd/3

doesnt work i get

-sh: eraseall: not found

like i said i only want to restore from backup.img but im finding it difficult for a dm600pvr.can anyone help me with the cmd command lines while in telnet ?.

that is squashfs method,,,,, your 600 will be using a jffs2 image,
images are not .img but .nfi!
use a backup plugin to get your backup.
( or at least take a look at the backup plugin and how the script works! )

ummm funny that cause pil-jade saves the backup as .img.im searching for backup plugin but cant seem to find any sorry for pestering but do you have a link.
also , after flashing the BER is 100% which is weird.thanks for the help.

ummm im a little confused now.if Pli-jade doesnt use .img and only uses .nfi then why when i made a backup image , why is it a ".img" extension ?.
if Pli-jade makes a backup.img the surely it must be able to restore the dm600pvr using a .img.
reason i say this is , making a backup is not what i want to do as i have reflashed my box with Pli-jade already , i want to restore the original image Pli-jade made 2 weeks ago.
thanks,.

Lol I had the same problem last week...ended up just putting the jade image back on instead of the back up image, there seems to be a flaw in the dm600 that doesn't allow it to except the "img" image that it created for some reason.

cheers

cheers for that , now another problem has now reared its ugly head.i didnt wanna open thread after thread so i here i go ;-
basically i just flashed the box back to how Pli-jade and start from scratch.i added the cable.xml and tried to bruteforce the box.
basically the problem now is when i try to transponder scan the "AGC" remains on 100% and never moves it remains permernatly on 100%.
the BER is more nr 1654560 rather than "0" and the SNR bounces between 65% to 80%.
when it does eventually find a transponder (this is after about 8-10 minutes of searching) the LOCK never actually gets a tick locked in box ,the "LOCK" box just flickers a tick on/off while the SYNC gets a tick and the scan box appears anyway.
i then scan with only the SYNC ticked and it finds 1 station and thats it and thats all broken.i've opened it up and re-seated the tuner but no joy.
has anyone else had anything like this ?.

Could be a corrupt image. The telnet method you used is for a dm500 so you could have corrupted your box. Try flashing the image again but using a null modem cable.

[loncell]

tried that with 2 diff versions of dreamup and same thing happens with the "AGC" lost now so any help would be greatly appreciated.
im not that clued with 600's , is there another image i can try apart from the the Pli-jade ?.

[caveman_nige]

Have you tried the image before jade, the PLi Iolite..

[loncell]

just tried it and same thing.this is looking more and more like the tuner or mobo got a problem.now its time to see what the sellers gotta say !.thanks for the help.

[loncell]

just as i was taking the HD out to send back i noticed this on the ASIX under the hd.now at first glance it looks like major bridging but on closer inspection it might be 3 legs purpously fused together.could someone do me a big big favor and whip the lid of there dm600 and look at the chip under the hd and see if its meant to be bridged.

[loncell]

sorry to pester guys but can anyone confirm by looking at the the picture above and comparing with their 600pvr that all 3 legs on the ASIX chip are fused together purposly.

[haider200]
