Which parts do i need for the JTAG-hack?
« on: October 18, 2009, 09:26:05 AM »
Hey guys,

I am reading the JTAG-hack guide on free60.org, but a couple of things are not so clear for me atm.

I am not so sure about the following parts:

Soldering iron and tin - got the iron (a Weller SP25, 25 Watt, that should be fine, right?), but i don't actually know what tin to order.

BAT41 diode - my parts shop (http://www1.conrad.nl/fas6/fh.php?fh_host=http://www1.conrad.nl&fh_session=/scripts/wgate/zcop_nl3/~flN0YXRlPTQyNTczMDYzNA==?&fh_pic_url=//media.conrad.com&fh_params=fh_location%3D%2F%2Fb2cconrad_nl_b2c%2Fnl_NL%26fh_search%3DBAT41&layout=b2c) has two of them, which one is the right one?

5x 100 120 Ohm resistor - don't really know which one to order (http://componentenfinder.conrad.nl/cpfinder.php?host=www1.conrad.nl&id=/scripts/wgate/zcop_nl3/~flN0YXRlPTE2OTA4MzY5NjQ=&attr_id=att_prodspec_1677&attr_value=120+%26amp%3BOmega%3B), how much Watt should it be???

Circuit indicator - i have a voltmeter, but what is this exactly?

3x 330 Ohm resistor - same as the 120, i don't know which one to choose (http://componentenfinder.conrad.nl/cpfinder.php?host=www1.conrad.nl&id=/scripts/wgate/zcop_nl3/~flN0YXRlPTE2OTA4MzY5NjQ=&attr_id=att_prodspec_1677&attr_value=330+%26amp%3BOmega%3B).

Thanks for helping!

koolfilmweerstand 0.25W is prima (maakt eigenlijk niet uit, hoe meer Watt hoe groter ze zijn)

Siliciumdiode 1N4148 100V 100mA will work : heb ik zelf bij conrad weg .. or that schotky diode will work

Gaan we in het Nederlands verder :)?

Ik hoorde dat die BAT41 zeer populair was, ik zie dat jij die 100V 0,1A versie hebt, die komt overeen, dus die zou goed moeten zijn denk ik dan.

Maar uit die weerstanden kom ik nog niet echt. Bedoel je op beide weerstanden dat ik 0,25W moet nemen?

maak in principe niet uit hoeveel watt je weerstand is, 0.25W is goed..

btw non-technical  :-X read link in my signature

Oeps, zit ik in het verkeerde forum, of bedoelde je dat niet???

Er staat in die guide 100-120 Ohm, is een grotere weerstand minder kans op schade, of waarom zou ik een van deze 2 nemen???

guys.. english. Other people may want to read this info too.
I do NOT give support by email, PM, ICQ or whatever. Anyone annoying me that way will have his balls removed. With a rusty butterknife. Slowly. And I'll enjoy doing it.

Wat voor soldeertin moet ik nemen?

Ik zit toch nog niet aan 20,- en de verzendkosten wil ik liever zo goed mogelijk gebruiken. Bovendien heb ik nu loodgieterstin (had me vader een keer gekocht), en dat lijkt me niet de bedoeling.

Since you chose to ignore the warning, I am locking the thread.
l-tyrosin: I don't. and even if I did, it wouldn't matter. the point is that this is a public forum for information sharing with everyone, not a personal chat.

edit: opened again. Stick to english.

Thanks for re-opening.

Mij last question was: I don't think I have the correct tin a.t.m., who can tell me what kind I need from this pages: http://www1.conrad.nl/scripts/wgate/zcop_nl3/~flN0YXRlPTI0NTgyNzY3MDM=?~template=pcat_area&p_selected_area=SHOP_AREA_17587&p_load_area=SHOP_AREA_17587 ?

Loodvrij soldeerdraad = lead free solderwire
Soldeerdraad = solderwire

--- Got it ---

Looks like you can solder lead-free. But I did understand that a 60/40 proportion is recommended?

I read that soldering lead-free wil require more heat, sow i'l skip that I think.

it doesn't matter which kind of solder you pick. lead free solder is generally more healthy, at the cost of not having a shiny finishing

Alright, everything is ordered.

100x 330 Ohm (only 1,80)
100x 120 Ohm (only 1,80)
2x BAT41 diode (in case I mess up one, or one is DOA, or something like that)
Weller 20 Watt small soldering-iron (my current one is a bit huge in my oppinion)
FLUITIN 0,7 mm with flux-core
A soldering-iron holder (my current one is a bit cheap)

That should do it i guess. We'll see!

Thx for helping everyone! I'l keep you posted!

330ohm resistors are out of the question.
the new jtag points for Xenon do not require the use of 330ohm resistors anymore:

you'd been better off ordering 100 switching diodes :)

Mmm... I still don't know what digram I have to use. Everywhere I find Xenon diagram's, but my Xbox 360 is a Falcon. So for sure I just bought it like this (without having to order another 3 times or something).

About the resistors: I don't care about that 1,80. Buying that much switching diodes wasn't an option; they are 0,37 p/s. Buying that one a 100 times would have costed me 37,- :o.

Can you collect the right diagram's for me???

It is already bookmarked for over an week :P.

But I still don't fully understand it. Do I have to ignore the Xenon diagram's completely?

Could yo give the links to all the pictures I need, I did some research, but it's not fully clear which ones i need to use (I understand I need multiple).

apparantly you need Falcon diagram, coz you have Falcon (solder 3 wires, two with diode)

then you solder the LPT cable to your 360 motherboard, points are all the same on different motherboards:

some people require a diode on J1D2.4.. but i don't

To complete the whole picture:

I need to solder the LPT1 cable like said in the Xenon diagrams (http://img200.imageshack.us/img200/3346/xenondiag.jpg is the best one i found yet, i think).
And the hack itself using http://i.imgur.com/Fdjmi.png?

But it generates some more questions for me:

What about the resistors of 330 Ohm that were not required anymore (you said), but are still in the Xenon diagram's? Should I just ignore them? Or should i solder them following the Xenon's insctructions.
And what's up with this picture: http://pictures.xbox-scene.com/xbox360/free60/diagram.jpg?

Sorry for keep shooting questions on you, I just want to know for sure.

Seems like you're almost on the right track. You do solder the LPT cable up as it is in the first Xenon diagram. The second one that shows the diodes by Gouki replaces what's done with 330ohm resistors. So instead of using the resistors, you use diodes and solder it all up according to Gouki's diagram. The third picture is an extra step needed by boards that aren't Xenon, like Falcon and Zephyr. You need to do this extra step otherwise your project will fail.

In this order..

1: Make the LPT port per the first diagram you have in your previous post.
2: Instead of using 330ohm resistors, use the second diagram by Gouki. This is a more efficient setup and electrically safer compared to using the resistors.
3: You then wire up the steps shown in the final diagram in your previous post. After that, you're good to dump and flash.

It seems like brain surgery, but it's really just as easy as popping a pill. If you screw something up, you may as well never pick up a soldering iron again till you've got some major practice.
