qsb´s guilty for rrod??

[LopoTRI]

hello,

i want to know if any of the qsb´s (post-qsb, jtag-qsb, nand-qsb-v3) have something to do with the southbridge of xbox.

i bought a falcon with dash 15574, i installed r-jtag with the qsb´s, made a xebuild 16537.
on testing it glitches only with aud_clamp, resistor 470, and dip 3&7, in 8 seconds.
i installed fsd 3, dashlaunch 3.10.....
my first option in fsd3 was to set the fanspeed high. then i made my configs....
i copied a game from dvd to hdd in f3 to test and play it.
when i saw that all works i just want to fine-tune the r-jtag.i test some dip´s again.

then suddenly i become a rrod (3 led´s). i google it, some wrote that is overheating, and on "xboxexperts" it stays that the "southbridge" have a problem.

After the first rrod, i put stock firmware back, but the rrod comes always after 1-5 minutes. and with r-jtag and xebuilded image it won´t glitch anymore and error E79 comes...

So i want to know if any qsb can be the problem for the rrod, or is the xbox dead, then i desolder all qsb´s again....

Tuning r-jtag will often result in rrod until you reach optimal setting at which point it shouldn't rrod anymore

When you boot stock nand, you have to make sure you disable r-jtag.. if you still get rrod with it disabled, then its hardware related and nothing to do with qsbs

E79 means there is an issue with your wiring or qsb

when i try the stock firmaware, i desolder only the 3v (red cable) from the r-jtag. i thought it´s enough or not??
Or have i set the jtag-qsb to "off" too???

 

[chase]

R-jtag uses 5v.. u may also need to switch off jtag qsb

If console boots stock nand and then after 1-5 minutes rrods, then its hardware related.. did u get the secondary error code when booting stock nand

Have you tried the standard cpu_rst point? (D)

 

[LopoTRI]

yes i tried first standard cpu_rst point. after it not glitches, i made the alt_cpu_rst....

my secondary rrod is 0010...

rrod and this error can be common on rjtag installs until you get the optimal settings honed in imho.

0010 usually comes up when xbox shuts down because of wrong R-JTAG settings

ok I got rrod then it stopped because I found correct settings first don't bridge the voltage jumper on r-jtag chip then turn dip 5 4 or 3 and 7 on then one by one turn on dip 1 and test then if still rrod turn dip 1 off then turn on dip 2 and so on. then if all don't work try voltage jumper 1.2 and 1.8 volt and go through all dips again. This happened to me I got mine to go to post 65 and glitch it does not go past this because of bad jtag aud clamp install which I ordered new one. When I did get RROD it took me about 30 seconds to 2 minutes for this to happen. Also when you boot stock nand desolder 3v red cable from coolrunner/jtag chip. also here is alt cpu point when I tried first one I got rrod and no attempted glitch also check post out ribbon cable that also could be. I only know all this because of when I had a problem with my r-jtag allot of people helped me and I then new what was wrong with it originally it wouldn't even a temp to glitch no green light indication that its glitching nothing then if wouldn't boot it would just keep attempting to glitch then I hit a setting where it appeared to give up but in reality it glitched successfully but jtag qsb was bad indicated by the cr3 pro rater also do rater and post them these people will tell you by that most likely

@ teknogod17

i tried it all before i began to post. finaly i flashed stock firmware, desoldered the r-jtag and let the qsb´s. the rrod still comes after 1~5 min. so that was my question if the rrod can come from qsb´s.
i desoldered the jtag-qsb too, let the post-qsb & nand-qsb, but rrod.
so i think it only can be hardware related how "chase" it say.....

RROD after 1-5 minutes on stock nand with 0010 is for sure not jtag or qsb related .. gpu and/or southbridge needs reflow if I remember correctly

yea if you removed everything some things physically broken and by everything off do you mean everything that's white. so ya if I were you get someone to re flow it or sell it as parts and buy a jasper jaspers are nice because they use a much better psu/power supply and don't get hot (unless you bury it is something and block air vents) its also because of the power supply I think there even cooler than slims. one more try find a donor nand somewhere and use your cpu and write the donor nand to your xbox I doubt it but I'm just talking out of my ass it could be a bad nand(a donor nand is a nand backup from other xbox of same type I believe it need to be same mobo but not shure

also it seams unlikely but just you picking up the xbox motherboard might of just warped enough for the solder balls to rip off cpu/gpu. next time ovoid holding bourd on edge always hold with two hands not saying thats the prob just a possibility.

to the op: if your in usa i wouldnt mind checking this out for ya and possibly fixing it.pm me if interested.

update:

today i desoldered all qsb´s too, and now i am playing "crash - mutants" more than 1 hour. i powered off and on 5-6 times too.
i can play without problems, no rrod comes....

and to say i am from germany...

Which means your soldering was at fault.

 

[nofeloniesyet]

Which means your soldering was at fault.

yup,as most issues you will find in rgh/jtag scene will be.if you dont know alot about soldering/have alot of skill,its not hard,to get a couple pads on ur qsb bridged together from underneath the qsb,where its invisible to the naked eye,however,a multimeter wouldnt of lied to ya,you could have checked for bridges in 4 seconds,i kinda assumed you had already tbh,lol.i shouldnt assume though,and i know this already,for example,when i first met oggy,i thought he was a straight,non pedophilific guy,boy was i wrong

Update 2:

Damn what a day....
After i desolderd all and see that the box works with the stock nand, i soldered the r-jtag with the qsb´s again to it.
Looked more times that i make nothing wrong. Then i flashed the xebuild 16537, i see that the r-jtag glitches, but xbox don´t start.
Best results for me come with aud_clamp, 470, dips 3 & 7, 1,2v.
My box boots within 8 seconds.
I began to play my "crash".... after more than 2 hours and many power off/on i see box works well witout rrod, that makes me happy. :biggrin:
Then i began to "finetune" and test the dip´s and the voltage. Suddenly the r-jtag don´t glitches anymore. The rrod comes... :facepalm:
I was frustrated, flashed my stock nand, desoldered the 5v and gnd from r-jtag, but the box won´t boot....
Then i saw something...
When my box boots fine my cpu_rst-cable was....



When the r-jatg don´t glitch, and the rrod comes, my cable looks...




Then i hotglue it to my first position....




And see my box boots to F3 within 8 seconds and i am Happy again...

So my solder from my first post was correct, only my cpu_rst-cable made this... :facepalm::facepalm:

New question:
To finetune my boot-times with the rater, it only works with the J-RProgger? Cause i have only the Nand-X unit.
