Guide: Flash and Backup an Image via Telnet

[Devilfish]

Telnet Commands

To flash an image using Telnet

This method will only work with a .img image file.
Rename the image file to backup.img
FTP the image file to the /tmp folder on the dreambox
Telnet to your box and paste the following command:

cd /tmp && eraseall /dev/mtd/3 && cp backup.img /dev/mtd/3 && reboot


To telnet, click START > RUN and type Telnet ip.address.of.dreambox
A command window will appear, enter username root and password dreambox.

To backup an image using Telnet

Telnet to the box and paste the following command:

cat /dev/mtd/3 > /tmp/backup.img

FTP to the box and navigate to the /tmp
Here you will find the backup.img file.

[dechef]

i did the following: click START > RUN and type Telnet ip.address.of.dreambox. But nothing happens!!

[mpmaho2]

Wish I checked out this forum sooner. ould have saved myself a lot of frustration

[mpmaho2]

Now I get it.
Put .exe after telnet, eg telnet.exe

[mpmaho2]

Guys, Help.

Just done the following:

Dowloaded the DW 2.0 image
Renamed to backup.img
Placed in tmp folder

Then followed the instructions below.


Telnet to your box and paste the following command:
Code:
cd /tmp && eraseall /dev/mtd/3 && cp backup.img /dev/mtd/3 && reboot




My dreambox has now gone from terminally ill to deceased.

Powered up and nothing, no menu, graphic, not even a flicker. Just a very troubling black screen. I have now lost the connection to my laptop also.

Crap, my mate won't be pleased. Although it's his own fault for randomly pushing buttons after the NTL blackout.

you may have created more problems than solved m8, if its a bad flash you,ll need a null modem cable and dreamup software to rescue the box.

it will flash a new image to the box safely, i always use the null lead to send images to mine, it takes longer but is safer and you can rescue it if it goes tits up.

hopefully you already have a null modem cable at home, if so plug it in your pc and box and use dreamup software to send the image to the box.

for people who are not into telnet and fxp it is the easiest way to go.

start software select com port1 click connect, plug box in(power) then flash image, simple no going wrong but it takes a bit longer than the other ways.

[mpmaho2]

It's not quite a paper weight just yet then?
Better nip out to PC world then. Local PC shop doesn't have the right cable, or informed staff for that matter. They asked "what's a null modem cable?"

[allycoops]

maplins will be cheaper.

wait till one of the guys say this is the correct one before buying

http://www.maplin.co.uk/Module.aspx?ModuleNo=97740&criteria=null%20modem%20cable&doy=9m4

[mpmaho2]

Just checked my pc. I don't have a 9 pin serial port. Will this 25 pin male to 9 pin female do the job?

http://www.maplin.co.uk/Module.aspx?TabID=1&ModuleNo=97737&doy=9m4

[Devilfish]

I'm not 100% sure if that 25 pin - 9pin will work, never tried it before.

You will need to find an old PC or laptop with a com port or you can get a USB to Serial adapter.

Remember that you need to have an established connection between your dreambox and PC before telnet will connect.

You do not need to put .exe at the end. If it doesn't do anything, the connection between the PC and dreambox isn't right, i.e. you're not using a crossover ethernet cable (not the same as a standard ethernet cable) or your IP addresses are not correct.

[mpmaho2]

I bit the bullet yesterday and drove through rush hour to get to Maplins. Worth the trip. A vast array of null modem cables clearly labelled, and just inside the door of the shop. Had been to PC world earlier.....useless.
Anyway flashed the DW 2.0 image with ease at the first attempt. So much easier than the ethernet method. Wish I hopped in the car sooner. All is rosey in the dreambox garden again, not that my mate will even understand the torture I went through to undo his random button bashing.

Now I just need the new keys for Dublin. Will have a look around the forum for updates.

Cheers for your help dude.

[dunryc]

you could always make you own null modem cable or " impovose one " by hacking whatever cables you already have in the house :idea:

http://www.doom9.org/DigiTV/images/dreambox/Null_%20Modem.gif

[fcuk]

Is this the same for the DB 500c?

[dunryc]

@fcuk i flash my db 500 c with my old dbox2 null modem cable so yes mates

[Ciaran500]

Thanks for the guide Kaos. Saved me having to drag out the old PC with a serial port to flash my friends box with some bastardised version of Enigma on it.

[biju007]

can i user it through router

[C64]

can i user it through router


Yes mate, a router will be fine to use.

Telnet Commands

To backup an image using Telnet

Telnet to the box and paste the following command:

cat /dev/mtd/3 > /tmp/backup.img

FTP to the box and navigate to the /tmp
Here you will find the backup.img file.

Hi, I'm planning to backup my patched & working image and found ur post. I read that there is very little free space on a 500c, so I was wondering how could a 5/7mb backup image fit onto the 500c in the /tmp folder?

[Devilfish]

The /tmp folder is a separate memory location that /var.

There are 3 locations...

/var - this is the writeable section.
/tmp - this is a separate memory location.
the rest - this is a read-only section.

[tinbox11]

would there be enough memory to store the backup image?
I checked on the box it suggetsed /var only has 80k left while the rest is 100% full. you can use the command to check how much memory is free; free under the telnet screen.

[tinbox11]

I found using null modem is the sure way to flash image, while ehternet is fast but as the falsh working its way you loose the connectivity, hence not a complete flash. At least I had failed twice using such method and null modem works all the time.

did anyone get null modem flash speed higher than 10kb/s?

[CyberBob]

Do you still need a crossover ethernet cable if you are connecting through a network switch.

[Devilfish]

No. If you're using a switch/hub/router you can use a patch or standard ethernet cable.

Although most modern routers will work with a crossover cable too.

[CyberBob]

To backup an image using Telnet

Telnet to the box and paste the following command:cat /dev/mtd/3 > /tmp/backup.img
FTP to the box and navigate to the /tmp
Here you will find the backup.img file.


I did this and the image is there as promised but when I try to copy the image to my PC my FTP client closes the connection without transfering the file.
I would like to keep a copy of the original image even if I cant identify it.
The telnet says BusyBox v1.01 but since I am using the dreambox manager suite v2 I am not sure if this is my image id or if it is the telnet client id.

[Devilfish]

It could be your ethernet cable that's fault or the ftp program that doesn't like something.

Reboot the PC and the dreambox and try again.

Remember, anything in /tmp is lost when the box is powered off or rebooted so you'll need to paste the backup telnet command again.

I wouldn't bother with any 3rd party dreambox program. Use a proper ftp client and you'll get much better results. I use CuteFTP but FlashFXP is also good. Or use internet explorer. ;)

Put this into your address bar of IE or Firefox...

ftp://192.168.1.101

(replace the ip address with your own dreambox ip address)

Navigate to /tmp and drag the .img file out like any other windows explorer window.

I was using cute FTP and on other operations like copying keylist files or the updated roms it was doing just fine but had no joy copying the image from the dreambox to my pc.

also I tried flashing the dw2image onto my box using telnet but it stopped the process after deleting all the files from the box and could not find the image in the tmp folder as it no longer existed.
now the box is dead and it looks like I am going to have to get a null modem cable and use dreamup as many people recommend.
This is not a complaint just information,and I am still grateful for all the help I have recieved up till now.

[Devilfish]

When you issue a telnet command, there's no error checking, it does what you tell it to do so you need to be careful.

Also make sure the image name, i.e. backup.img, is the same in the command and the actual file.

At the point where it errored that you hadn't copied the file across, you could have still copied it to the box and issued the command again. All it had done was erase the flash, you still had control of the box. Not to worry, dreamup will defo sort it out for you.

DreamUp did sort me out and I have flashed the dw2 image onto my box.I guess losing everything on the box is the cost of using unfamiliar software.
On the up side dreamup was so simple to use that losing the contents of the flash are less of a fear for me now.(confidence is high).Still I obviously have a lot to learn.
Thanks for all your help Kaos.

hi many thanks for the info i will try to understend all of this
bye for now

[uskuz]

How could be made to download image from internet, and restore it with a script?, main problem is to get the image downloaded and know it is 5 - 6 mb image and not not page found, downloaded by wget to /tmp/imageupdate.img for example.

Sometimes i try to get a file with wget i get that it can?t connect to server.

Thanks

[badaas]

excellent stuff, first time for me updating dm500c since buying it, stable system :)

[Ma24]

[alliv]

--------------------------------------------------------------------------------

well i had the 600 working on cli image and wanted to try a different one ,dreamup would not flash. [useing laptop / vista and comport converter ] so i thaught i,d do it as you suggested with telenet. ie
mount -o remount,rw /boot
rm -f /boot/*
reboot
used putty program to do this. i had ip set on the box and i could telenet to the box before this. after putting in the command mount -o remount,rw /boot
rm -f /boot/*
reboot the box went off and came on with red light flashinrg and the odd green flashing light every now and again. now i.m stuck,any idea,s m8? thanks for the reply.also tried restarting the box with power button held down , still no joy.???????

I am doing a friend a favour by trying to get his DBox up and running, and wondering do the telnet commands that are detailed on this thread work on a dbox.
I have been using this method for my 500c and have never had a problem, so I was hoping I could flash a image using this telnet method for the DBox.
Also I know it is doubtful, but is it possible to flash DK1 image on a DBox or is this image specific to dreambox

[bajan2nv]

is it easier to use telnet dcc or dreaup?

[mattwills71187]

just wondering if you backup the image off one dream box is it possible to copy it over to another box so there running on the same flash software

my box won't allow you to click on to flash as it is greyed out.. what am i doing wrong...?

[carlowchris]

followed your instructions to the letter and my box is useless now,i've only a green light on the front,nothing else but a black screen,no menu's or welcome screen,channels or anything,any ideas?????????how can i rescue this now?????????????

[Ginkman]

is there a similar way to use telnet to make a .nfi backup image for a 600....

[dingboy9]

Having problems with Dreambox tools v3
When I run universal dreamup I get an error "there is something alive with IP 192.168.xxx.xxx in your network that is not a dreambox. Dreamup may not work properly"

Any ideas?

[blowfishcable]

hope this above will work for me.

[mpikguru]

thanks !!!!!guys!!very helpful if you dont have dreamup!!!!

[ronlkh]

Hi, Will this command work for image backup from Dreamup?

[godsakes]

oh god...

i renamed the image wrong when i ftped it - i typed in the command and it got as far as erasing but stopped when it couldn't find a matching image file

i then repeated the command and get the error message:

"cp: unable to open '/dev.mt/3': no such file or directory"

what should i do?

edit:

nevermind i restarted my telnet client and redid the commands - which seems to have done the job

I own a DM600.
I downloaded the latest gemini-460-dm600pvr-200812192032.nfi.zip
I unzip it, renamed to backup.img and uploaded in DM600/tmp

I run the command:

root@dm600pvr:/# cd /tmp && eraseall /dev/mtd/3 && cp backup.img /dev/mtd/3 && rebootBut it fails

-sh: eraseall: not found
root@dm600pvr:/tmp#What shall I do?

[halfdene]

Thanks, I used Dream Up last time but next time I will try this.

[zlate]

When I type the command Telnet ip.address.of.dreambox it says telnet not found. What should I do. Do I need some software or???

[Bulld0g]

What OS you using m8. ? Telnet was stopped in Vista. Look in downloads for a prog called putty. you can run tenet on this on vista and windows 7

[Rhinotoby]

Telnet commands seem to be a dangerous way of doing it as i fried a dm 500-c doing that. Much easier to upload dm.img to temp via ftp, rename to root.cramfs and do a manual update.

[astropalmo]

devilfish thanks a million.
i've been trying to sort out my dreambox 500c which i recieved today. it got enigma image and i was unable to get any channel but i just telnet the digital kaos image with your tutorial. your are a star. regards. :congrats:

[zlate]

I don't know the pass for my dreambox is there any way cracking it or reinstaling it without losing the settings or any way to backup or download the bouquets at least

Don't know what's best image so I picked the NabiloBlackHole_DM800_012 image. Q. Will ftp'ing it to /tmp dir and following the same telnet command apply this image to my DM800.
I did all this ages ago on my DM500, does the same process apply with DM 800?
what about cams etc, is there an idoits guide for DM800 on the forum somewhere, Sorry I am abit numpty due to lack of practise playing with Dreambox for more than a year or so....

this telnet dosnt work with the dm800 as the images for this box are E2 images as with the dm500 they are E1 images

the best way to flash it is via webbrowser
have a look in the sticky,s in the dreambox sat section how to :)

[dbdos]

Can flashing via telnet be used to replace an image? I'm attempting to replace an old Gemini image on a dm500c with the latest Pli-Jade3 image. I don't have the null modem cable, thus my reason for exploring this method, as I can't use DreamUp.

[baretto]

For those with Vista/W7 who cannot get Telnet to launch after you have enabled it in your "Programs and Features" you can use an alternative program to Telnet called PuTTy Found here (http://www.chiark.greenend.org.uk/~sgtatham/putty/)

Works a charm. Thanks Devs for this. Saved me from getting a Null Modem Cable ;)

[dbdos]

I'm assuming you flashed a brand new dreambox, as opposed to one with a previous firmware, e.g. gemini.

[caveman_nige]

I own a DM600.


I run the command:

root@dm600pvr:/# cd /tmp && eraseall /dev/mtd/3 && cp backup.img /dev/mtd/3 && rebootBut it fails

Odd, i am getting this as well.. never had it before.. trying to flash a backup of pli iolite image from one dm600 to another dm600.... has anybody else had this, what did they do?

Oh no. I decided to flash my Dbox again but...

I did all this without placing the backup.img file into the tmp folder of the DBox :(

Now my Dreambox is completely dead because i think that command deletes everything. The light is on but theres nothing on screen even the remote does not work

How will I flash my Dbox now? Knowing that I have no idea what the IP is.

HELPPPP! :(

But I did not copy the backup.img to the tmp folder. The commnad prompt showed the erase complete. I am afraid I am left w a paperweight :< unless someone can help.

The box has green pilot on and that's about it. I see nothing on the tv and even when I run dreamup - the connect connect the dreambox.

Any inputs or suggestion to salvage my baby. Can i just copy the backup.img to the proper place?

thanks for your kind patience and understanding w a noobie like me. HELP HELP

Have you tried hooking it up to a RS232 port using a null modem cable, and reflashed it that way?

I've rarely had "black screens", so I've had to use Dreamup to flash the receiver, as opposed to flashing by network

Managed to unbrick it by reflashing - none the usb to serial, x cable, nothing thing worked. thought abt vuying express card but hear win7 is not good. too many ifs and buts conditions, it was quite daunting whether to throw so more good money at ""bad"" technology

last resort was to blow off the dust of an old p3 box which has not been used and sitting in the storeroom. Dont even know why i kept it in the first place???.

Viola - dreamup began talking to the dead dm500. Amazing !! sincerely think dmboxes need to be upgraded in this respect of null modem and serial port connectivity. How many of us actually have a good working p3 or pp4 sets?

Anyway i am happy now. Thx for the input.

hi m8
the port in my laptop is 15pin (blue coulor) and the port in my box is 9pin.i still can use the null modem cable?some one told me this blue port is not for flashing and i can use usb/9pin port cable is that correct?

I think you'll find that the 15pin port is a VGA output mate... Is it a socket? and does it have 3 rows of holes?

[bshaik]

good post i really liked it.

[kiv]

Any expert can guilde me to download the image file? Still searching for the null cable thou, was wondering is there a adapter from 9 pin to usb?
Also, if the card expired, is flashing still useful? Really new and on my learning path, appreciate any help here.

I have the same situation, I used the command

cd /tmp && eraseall /dev/mtd/3 && cp backup.img /dev/mtd/3 && reboot

and my page blank out. I think i need some null cable using a netbook without rs 232 outlet only with USB port.

In SG, any place to buy any kind of cables to connect using usb? Really need help, now my 500c cannot connect via lan cable. Blank, any expert, please advise and help please.

I'm having this error. I have already change the file name to mybackup.img via flashfxp and place the file in the tmp folder. Anyone can help me out here?

[chlim]

Going to try Waqasahmed suggestion using DREAMUP and serial cable to clone one Dreambox500S to another Dreambox500S. Does it mean I have to first connect to one Dreambox(source) to copy its image, disconnect it and then connect the second Dreambox(target) to upload the copied image? Sorry if I am looking for step by step procedures for the sequence of connecting the serial cable as I am a newborn.
Many thanks to the useful posts in this Forum that has increased my understanding of the Dreambox.
Help appreciated.

To backup an image using Telnet


Telnet to the box and paste the following command:



cat /dev/mtd/3 > /tmp/backup.img


FTP to the box and navigate to the /tmp
Here you will find the backup.img file.



I've got a DM800C HD PVR. Trying to backup the image that comes with the box so I can reflash it later if something should go wrong. I've managed to telnet to it and realised that there is no such directory /dev/mtd/3 in it. I can only find /dev/mtd3 in /dev:

root@dm800:~# ls -l /dev/mtd*
crw-rw---- 1 root root 90, 0 Jan 1 08:00 /dev/mtd0
crw-rw---- 1 root root 90, 1 Jan 1 08:00 /dev/mtd0ro
crw-rw---- 1 root root 90, 2 Jan 1 08:00 /dev/mtd1
crw-rw---- 1 root root 90, 3 Jan 1 08:00 /dev/mtd1ro
crw-rw---- 1 root root 90, 4 Jan 1 08:00 /dev/mtd2
crw-rw---- 1 root root 90, 5 Jan 1 08:00 /dev/mtd2ro
crw-rw---- 1 root root 90, 6 Jan 1 08:00 /dev/mtd3
crw-rw---- 1 root root 90, 7 Jan 1 08:00 /dev/mtd3ro
brw-r----- 1 root disk 31, 0 Jan 1 08:00 /dev/mtdblock0
brw-r----- 1 root disk 31, 1 Jan 1 08:00 /dev/mtdblock1
brw-r----- 1 root disk 31, 2 Jan 1 08:00 /dev/mtdblock2
brw-r----- 1 root disk 31, 3 Jan 1 08:00 /dev/mtdblock3

/dev/mtdblock:
lrwxrwxrwx 1 root root 12 Jan 1 08:00 0 -> ../mtdblock0
lrwxrwxrwx 1 root root 12 Jan 1 08:00 1 -> ../mtdblock1
lrwxrwxrwx 1 root root 12 Jan 1 08:00 2 -> ../mtdblock2
lrwxrwxrwx 1 root root 12 Jan 1 08:00 3 -> ../mtdblock3
So, how should I backup this box's image?

cat /dev/mtd3 > /tmp/backup.nfiWill the above command work?

Thanks

[Devilfish]

This method won't work with a DM800, I've been out the came for a ages now so can't help you further, sorry.

[smirnoff_rules]

u have to flash from the boxes webpage m8 , power up box with your finger on the power button . u will see message stop and remove finger and u will see an ip address , but that in your browser and u have an option to flash an image , search for it and flash

[Bulld0g]

As above, flashing this way takes about two minutes. When you add your bouquets etc and set the box up the way you want it, go to MENU...SETUP....SOFTWARE MANAGEMENT....BACKUP SYSTEM SETTINGS.

Next time you flash another image you can add these settings, as above but using RESTORE SYSTEM SETTINGS. no need to make a back up of your image when you can save your settings and just restore them to a new image. Takes about 2-3 minutes in total.

Hi, I'm using DM500(Sliver), currently only can watch normal channel.
I wanted to refresh but keep having invalid login.
I tried the username and password given (root / dreambox) but still fail.
Is there any other username and password can be use?
Thanks

[gringo 85]

Lol. If you're looking at a network cable, do not go to Maplins. You're going to get ripped off. If it's quality you want, then go on eBay and type in cat5e 350MHz and find some cable from there, but otherwise I'd not bother with Maplins at all

Hi,

Will the back up cmd work for mac OS?

[waqasahmed]

Hi,

Will the back up cmd work for mac OS?

Yes. The commands are for the linux receiver. You are only using telnet to send commands to the receiver, hence it doesn't matter what OS you are using to initiate the commands - All you need is a telnet client
