I had problems with BB5 unlock with DKU-5 cable, so i found this com cable and made it...and it works 100%

best of all...no drivers needed, just a PC/Laptop with a COM port!! (and some soldering skills)

p.s. i recommend using a DIL chip holder for the MAX232 chip to prevent damage to it!
Note: double check the orientation of the Capacitors and make sure they are rated at 16V or higher.

Hello bro,
Any chance of getting a PCB version of this circuit? Thanks.

well i just made the strip board version, sorry aint got time to deign a PCB version, i got 7 exams to revise for atm!

lol - Good luck with your exams! I've got an FBUS cable but for some reason it is not working with N70, but works with 7250 lol

***put two diods zener 2,7v from gnd to both rx and tx and ur cable will be ok

thanks for the strip board version man

one question... i have a CA-53 here, but i don't wanna cut it for the connector, can i use a USB female as output of the circuit and use ca-53 without cutting down it? it seems be pin-to-pin cable.

Thanks

first: DON'T cut up you CA-53 cable!!! that's not gonna help you!!!

For the pop port side of the cable, i actually took it from a basic serial cable ( just has wires, no circuit) which i has bought years back, and de-soldered the connectors from that...they are on ebay for a few quid, i'd just recommend getting one one of them, and building from that.

NOTE: you will still have to buy the D-Sub 9 connector cus usually the connector on the cheap cables off ebay only have 3 wires with molded plastic around the connector, so u can't really use that!

Good luck

There are 2 kinds of dku5 cable in the market.
1 with complete pins the others seems like 5/6 only.
the first 1 works and tested it by myself.
we all use it on all of our 5 shops.

yes just make make necessary connections rx tx and gnd. if not work just reverse rx and tx connections... and that will do...

Look for this post it is more easier to make com port with USB cable :

My cable only has 3 wires... I hope this one can still be used or will I have to reverse the Tx and Rx connectors? Also, is there any need to modify from the COM port end?

I have the same cable but it's not working for me :confused:

Ok, thanks for replies...

one question, why you cut the center lead of the transistor?

I made it this afternoon, but it don´t work, tomorrow i will test it again. What programa did you use to make the schematics?

Thanks!

ok, i fixed it, i forget make the bridges between capacitors and leads 16 and 15.

Works like charm! much better than the ca42 cable

thans!

i did it manually!!

the first circuit schematic is just a re-edit of the original (which didn't look as nice and less clear in my view!)

the strip board scematics, i originally made another circuit about a year ago in a desktop publishing program called pageplus (VERY VERY GOOD PROG!) and just edited it for this circuit! took about 1.5-2 hours though :S

good to hear ;)

hi guys
it's normal siemens data cabel. cut normal any nokia and siemens data cabel and connetc dku-2 pin out. voila
good luck toall

I got phone 6131.Can't connect one in any way (DCU-5,DirectCom,e.t.)After conecting to UFS phone become in local mode and after thet i got connection for reading info by DCU-5 for Dejan unlocker.

hi guys
it's normal siemens data cabel. cut normal any nokia and siemens data cabel and connetc dku-2 pin out. voila
good luck toall

can i use a siemens cable?
serial or usb?
thanks

serial only.......................................

serial only.......................................
any serial siemens?
or particular models for particular siemens phones?
how can i know which wires connect to dku-2 cable and how?
do you have a schematic or something like that?
serial cables for siemens from mobileaction.com are ok?
thank you very much

c55 and c45 cabel for com port
good luck

c55 and c45 cabel for com port
good luck
hi,
i buy c55 cable, i modified to work with nokia, but i can't read nokia e60 info(only read), than i make the dku-5 fbus with max232.
both cables read nokia 6020,6070 info but not nokia e60?
what's the cable that i need?
tnx

I have tested this schematic with 6630.
Yes this works 100%:)
I didn't use 7805 voltage regulator and 2 IN4148 diodes.
Instead of used 5V from the power supply of the PC.
Short circuited 4-6 pins together and 7-8 pins together of the D-sub socket.
MAX232ACPE IC was used.
Thanx LAD.

Yes, I always use this "pure" TTL-serial connection without drivers

Perfect with a power supply and 78L05 regulator.

Thank you so much great work keep it up

I tried to use this circuit to unlock nokia 6085 and it doesn't work at all. I have data cable CA-53 and the pinout is the same to dku-2 (http://pinouts.ru/CellularPhonesCables/nokia_dku2_cable_pinout.shtml). Is there the possibility that the cellphone 6085 don't have FBUS support?? (http://pinouts.ru/CellularPhones-Nokia/nokia_pop_pinout.shtml)

Anyone, please, give me some clue to unlock nokia 6085.

thanks in advance.

hello, any one can post the schematic !!! i can't see it .

thank for all.
