RGH 1st attempt to a corona need some advice

[fokeiro]

yeah i know is better but i suck so much at it lol

 

[fokeiro]

after i flash ecc do i have to remove the bridged resistors or it should ork fine like that ?

Leave them bridged.

getting boot but cr wont glitch no green light, ill remove and resolder everything

Did you power the Xbox on with DVD Eject button (boot Xell) to get your CPU key before building & writing a RGH NAND?

*Don't forget to disconnect the power brick from the console after each NAND write. Leave it unplugged for 30-60 seconds before plugging back in.

resoldered qsb straight to board, cr no green light , stay at red, yeah used eject for xell but cr wont glitch

Read this thread: http://team-xecuter.com/forums/showthread.php?t=93315

Did you write the timing file to the Coolrunner?

Check your soldering, especially CPU_RST.

 

[fokeiro]

yeah i did several and still no debug light i guess ill try diferent size blue cable

 

[fokeiro]

now i got green light i had the wrong cpu rst point, now just need it to boot to get cpu key

If your Xbox uses Winbond 2KB RAM, you need to use another ECC.

i dont see that chip anywhere, where should it be ? also should i try remove the r1r1 resistor ? i cant find it anywhere

Okay, use the normal Corona ECC (you don't have Winbond RAM), and remove R1R1 AFTER you get your CPU key from Xell.

 

[fokeiro]

ok just removed it guess ill bridge it back but didnt make a difference, this is my soldering so far

 

[Beaver_Buffcoat]

Don't bridge R1R1, replace the resistor. You can hold it in place with a pencil eraser while you solder it. Try moving the yellow wire on the post out QSB to 50cm.

 

[fokeiro]

sh*t i think i lost the resistor can i use another from a broken phat ?

 

[Beaver_Buffcoat]

Just leave R1R1 open (unbridged). If your QSB upgrade soldering is good, you now have to play with the post out and cpu_rst wire lengths. Maybe lengthen the blue wire to 20-30cm (wrapping excess wire around x-clamp) and connect the yellow wire to the 5cm pad on the post out QSB. Gradually shorten the blue wire 1cm at a time until boot time improves.

the postfix adaptor only goes connected to in 2 resistors right ?

The post fix adapter provides a signal path (simulating different lengths of wire with traces under the PCB solder mask) to the XCGPU pin where POST codes can be "lifted" by the Coolrunner CPLD.

It is soldered to two capacitors which act as an anchor point and are not a functional part of the QSB itself AFAIK.

 

[fokeiro]

idk if its me but this corona is been a ass to glitch

Double check your soldering, preferably with a multimeter. If all is good, connect your NAND kit to the PC, format the NAND, and write the ECC again. Disconnect power brick from console, wait 30-60 seconds, reconnect power. Boot with DVD eject. If it's still not booting, shorten yellow wire and connect to 5cm on post out QSB, lengthen blue wire and gradually shorten it until bootup time is consistent.
