What we need:
1. DCU-11 USB data cable (for k700)

2. Fastport for k750 with all pins onboard. I cut my from origonal DCU-60

3. Ordinal RJ45 phone box

4. RJ45 phone cable


So we start
The task divides to 3 parts:
1. To make a box.
2. Make wire for k700 connector.
3. Make wire for k750 fastport.


Open DCU-11 black box (on cable) and remove all wires that comes to phone and leave only USB wires.
Now we need to connect box's wires to chipboard like on the scheme below:

You also can take big picture (2568x1761)
There are 4 wires in RJ45 box
BLACK
RED
GREEN
YELLOW
And you can connect them in free order.
But for convinience i offer you to connect them in this way:
BLACK - GND
RED - +3.3V
GREEN - TxD
YELLOW- RxD
After that you have this:

So, close the box and it's ready to serve



Now we need RJ45 phone cable.
We have to cut it on 2 parts: first is need for k700 and second - for k750.
By default the RJ45 cabels wires have same colors coresponding box's wires.
If not then you have to note wich box's wire comects to wich RJ45 wire. And use this note to know wich wire is wich to connect.
Next we take k700 connector from DCU-11 and remove all wires from it.
Now we take first part of cuted RJ45 cable and prepare the cuted side.
For k700 we need only 3 wires:
BLACK - GND
GREEN - TxD
YELLOW- RxD
We have to connect them in this order:

BLACK - GND ==> PIN # 10 (GND)
GREEN - TxD ==> PIN # 6 (RxD)
YELLOW- RxD ==> PIN # 7 (TxD)
And connect PIN #9 (VPPFLASH) and PIN # 11(DC+) together on k700 connector.
K700 cable is ready to serve



Now we need second part of RJ45 phone cable.
In k750 uses all 4 wires.
Let's connect them in this order:

BLACK - GND ==> PIN # 9 (GND)
RED - +3.3V ==> PIN # 8 (VPPFLASH)
GREEN - TxD ==> PIN # 10 (RxD)
YELLOW- RxD ==> PIN # 11 (TxD)
K750 cable is ready to serve



Now you have 2 in 1 service cable for SE k700 / k750 phones.

Thanks to all ppl who help me with it.
P.S. Easy way to know more is flash EROM with DCU-60

@Darkmen,

Wow, what can i say....thankyou very much, very very good guide with clear instruction. Thread is now pinned!.

Home-made cables much more fun!

I've also made it an announcement (with the help of Darkmen ) for this particular forum as I thought it deserved the right to be on top of the other stickes as it's more of a general kind of help which won't become outdated.

I love this board

absolutely beautiful...

i love this forum more and more for each day..

I know what it's like

@Darkmen

Just thought I'd pop my head round the door and say jolly good show. Top stuff!

wow.
Nice work.

Much better to use SHIELDED cable instead of ordinal phone RJ45.
Because it haven't shield stable speed is only 115200 kbps.
On higher speeds it behaves bad (read\write operation fails).

I have a little problem . I have another DCU-11 cable.

I use original drivers which's come with it.
I've tried to shortcut 9 and 11 pin, but it doesn't work with SEFP but original functions stayed the same.
What should i do?
Does anyone have manual or scheme how to do your own k700i service cable?

And who will perlace RX and TX from Data to Service pins?

which pins are they?
i can't find k700i connector scheme.
Can you little help me please and give me the link to some scheme?

Do you read the topic? I think you don't!

I've read it, but look at my cable.

i'm sorry i've forgotten that there are bottom side of dcu-11, there are also connections to pins.
but i still don't know what to do
maybe http://www.esato.com/archive/t.php/t-17145
is that working?

I've tried it and it's working.

Ho-hum... I am thinking about getting this cable myself and modding it of course
But! If I get the newer model that grawp has I guess I need to unsolder the whole connector and then resolder it using wires in between and assemble it in a new housing, right? And the way I can see it there's nothing that would stop you from actually building both ends(K700 and K750/W800) into the same so that both are connected at the same time, right? Only thing to remember is to only plug ONE phone only at a time

Does the above appear correct? Will this cable let me unlock a phone and access a K700 using your SEFP plugin to remove the annoying Vodafone branded "features"(dungpile of ) and let me flash the firmware using DaVinci?

Can i use this service cable to flash my D750i Brown colour to Red colour without any charges ??

yea

Woooowwwwwwwww ...

Nice work.

Hi

I have problem with my k700 cable modding.

I have cable:




with wires like:


Looking at:


and my last foto i have pin configuration:
1 - empty
2 and 3 - RED
4 - WHITE
5 - BLUE
6 - empty
7 - empty
8 - empty
9 - empty
10 - GREEN
11 - YELLOW

Can you tell my how i can switch wires to get service cable ?
I made some test and i can't get it work correctly.

Thx

Is it a necessity to have the dcu-11 cable?
Isn't it possible to make a service cable for k750 without using a dcu-11?

[quote name='Grawp' date='2006-06-21 20:39' post='54875']
I have a little problem . I have another DCU-11 cable.



Izzit this type of DCU-11 also can used ??
if i replace DCU-60 with normal SE K750i handfree can or not ? Coz is
cheaper compare to DCU-60

thanks

hmm, does anyone know where to get these cables on the internet, or anyone wants to sell one of his?
I smoked my own cable...

Allright, I've now built this marvelous and wonderful cable, but if I try to access my wife's K700i with FAR and the SEFP plugin I will get to the prompt where it says "press power shortly" and when I do that the damn phone starts, every time... So I fired up SeTool from Topsony and when I press power on the phone my computer BSOD's "IRQL_NOT_LESS_OR_EQUAL" and the phone starts up... DOH... any suggestions?

hey all,
I have a wee query, where can i obtain a ordinal rj45 box? cant seem to find one here in UK!!!

maybe at the local phone company?

This is original DATA cable pinouts:

So you need:
1. 4.5 switch to 6.7
2. Cut 11 pin's wire and connect 9+11 tougether
GND on 10 - no changes.

Darkmen!

Have You got some experiences about SE Fast Port communication?
Is it possible to communicate with AT commands? Have You tried it?

catchme

Yes it's possible to use AT commands. Specs are here. 2005 is K750/W800

On some sevrice cables (RTS/DTR driven) - there are no problems at all - just plug it and it will work.
On 4-wires homemaden cables - there is a way too.
You have to:
1. turn off the phone
2. push power button (white screen appears)
3. plug fastport to phone quickly (until vibra acts)

When phone boots completely - you can send AT-commands to it/

P.S. Don't wait so long -plug fastport at the momet you see whitescreen. Phone detects cable on this step

I've tried it too,but SEFP doesn't recognize my phone.I connected pin 4 with pin 6,pin 5 with pin 7,and pin 9 with pin 11.
Can you or anyone else help me?
Does someone else tried to connect k700i to SEFP?

Can i make a service cable 4 K700 using SERIAL T28 Cable(AND NOT the DCU-11)?

Can i make a service cable 4 my K750 , following Darkmen's instructions BUT using the T28 SERIAL Cable instead of DCU-11??

Allright... Today I recieved my cheap china made DCU-11 copy and it modded flawlessly, worth to note here is that the original DCU-11 cable in it's newer revisions will not modify at all, it only crash your computer when you try and access the phone...

If you want an easily modifiable cable, go buy the cable they sell here: http://global.mobileaction.com

isn't phone cable & box are RJ11?
my phone box only comes with red and green, will it work?

I'm afraid yes
RJ45-network konnector

The colors used to recognize wires.
So you just know what wire you have Tx (for exampe) from box.

Thx
It's working gr8 on k700i

got the k700i cable but its a bit different... please tell me where to weld the 4 wires on this scheme...
I attached the scheme of the circuit..

I did'nt change anything on USB connector.

I make some switches on my SE connector:
switch wire from pin 4 to 6
switch wire from pin 5 to 7
connect pin 9 and 11 tougether
don't remove cable from pin 10

Remove all other wires and pin connections.

I mean for a K750i... i connected the 8,9,10,and 11th pins just as the tutorial states, now what do i do with the usb thing or which end do i connect to which.

pin 1 - empty
pin 2 - empty
pin 3 - empty
pin 4 - empty
pin 5 - empty
pin 6 - empty
pin 7 - empty
pin 8 - RED
pin 9 - BLACK
pin 10 - GREEN
pin 11 - YELLOW
pin 12 - empty

now the USB end from the K700i cable has got RED BLUE WHITE and GREEN
What do i do with those?

hello, everyone here. i m understand how to create these 2in1 service cable, but 1 thing i hav no idea about is how to connect these 4 wires to pins of dcu-60? cut it into 2 parts? anyone can detail about 4 me please...

thanks

OK.. let's say that I want to buy a modern DCU-11 cable as Grawp shows in his pictures.

CAN someoane show us how to mood the pins and wires in order to get a service cable?
I want to buy one DCU-11 in ordet to make myself service cable for k750i.

Darkmen... I would apreciate verry much if you can told me (us) how to modify this kind of cable. I want just
a service cable home made... and i think i have at my disposal only DCU-11 cable - modern looks with large SE plug.

Manny kisses in advance.

The cable you show pictures of is not the newest DCU-11 cable and can be modded, I have one of the newer revisions and it just won't be modded into a service cable, the most probable cause is that there is a small chip detecting the phone's "service mode" answer and shuts down communication. I modded my cable, triple checked everything twice and every time I tried to use the cable it would crash my computer. Conclusion: Newest SE DCU-11 is not moddable... Better get one of those cheap china made DCU-11 copies as they will mod very easily. My cable installs as "MAT USB to SERIAL bridge" and simply is a USB-T28 data cable...

Funny part is that i cannot buy from ebay. And I live in Europe - eastern part. So ... I don't know if someoane can deliver here.

I will check to see if someone has an old DCU-11 cable.

DSS-25 cannot be modified to become a service cable?

Hi!!!
Can I use this cable with my w810 and totalmultiserver (buying log)?
Thanks

OK I bought an DCU-11 cable. it looks like this.


Someoane with experience can tell me: 1) can it be mooded to a service cable?
2) How can I do that? (i bet a lot of cables look like this)

I attached pictures of the board. For details PM me.

Yes you can, I've used mine with TM and unlocked a W810i, works perfectly.



This cable should be moddable, look at the post above for correct pins to modify, it has the same chips as mine but not the same design so I guess it's a little older.

I was affraid that i got the new type and cannot be moodable.

seccond.. foxen will you be so nice to tell me what driver do you use? because on the CD i got is only SE software (MMS, SNC, bla bla) but driver is absent.

regarding pin configuration.. if i figur it out how things goes... I will post here.Click to view attachment


FOXEN will you be so nice to post some pictures of your mooded cable. just to have a "start point"Click to view attachment

LE: attached is the Working driver... for the ones who really got this problem. And pictures of my cable.. maybe someoane can tell me What can I do with that blue cable.. and how to make connection.
