Im so so sorry.
I don't think there is anything to do now.
Well this console probably really died but let me to explain this problem in other hands:
I state that I have a jasper 17919 with CB 6750 and I have done the RGH. I use google translator so sorry for my bad English.
It worked fine until he have had the unfortunate idea to do some experiments to improve the speed of the boot was on the minute and a half, I say was because now dead :°°° .
If we write over the original nand, I turned on with a E79 error. When I write above the nand hack, I just left them black screen;
the CPLD NOT RUNNING.
(and this means for me, that connections are not ok! fcuk! I guess POSTBIT, and I also found out why!)
As suggests, the POSTBIT I went shorted to the GND !!!
I have bricked this jasper more too, fcuk, because in fact the harbinger, was a short circuit the first installation time I reassembled the case, powering and immediate short circuit (RED LED on the power supply)
After few seconds, which was then restored and the console worked but sometimes frezze at botting!
well next, I do testing for more a day I played with FSD many more, downloading covers using ftp and smb share and unlock all the unlockable ever I own but ... sometimes under booting I see, initial swirl logo of 360 freezing or some times I see hdmi output to resize in little resolution mode (I guess 576p or less), and general boot time over a minute. ho fcuk man! a very chain of malfunctions here! days go by... I are able to run games without hangs but this is old story for me man.
NOW:
How to say ,when I redid the RGH for second time on this shitty jasper, and I closed the console, fcuk! you went back a short circuit, so I shot words for all gods on sky, fcuk! ... and checked for connections by CPLD and all wires I marked with the multimeter a continuity between vcc and gnd on the pads of the chip, and I immediately thought the worst, and in fact I had reversed the POSTBIT with the PLL_BYPASS! Next how to do?
Do it this man:
I cleaning it well as my best experience , hahah :| , and tired all the short between vcc and gnd is restored.
Now I find by myself this fuking short circuit between POSTBIT and GND would not know how to solve!The alternative point of POSTBIT under the heatsink marks on multimeter report shorted same as FT6U and GND of course! However, I have a "wide" ohmic value of 6 ohms (console on standby power) fcuk what do you mean? I not found anything on the forums to explain me this.
Now??? I tried to powering on. Well, with turned on green central led of panel is only fuking led i seen ON but now retry to mesaure the resistence. Surprise! the multimeter report OPEN! This is normal for digital circuit? I guess not too normal. but I not know really. and still cpld not running anymore.
Please someone could confirm that value among the GND<>POSTBIT and /or the circuit must be opened? Since I found this on an old zephyr, which is RROD I do not have absolute certainty about what is the truth.
I would be happy if someone had an 'idea of what could be done. I have run out of energy, there are 6 days madness above! many Thank!
Follow some pics of my soldering, They are good at soldering, I modding consoles from 2003.. (ps2 xbox)
