Slim RGH Help. No power

[homegrown]

I got a slim the other day that has TX nandx QSB and TX Coolrunner. It had the ecc flashed to it three times and every time the center light turned red on the ROL after 30-40 secs of the coolrunner trying to boot reloaded. He used multibuilder to make ecc.

I removed the rgh and tried to flash original nand back and got some crazy errors in nandpro when writing that I have never seen before and couldn't find a thing about it either. They were errors in different spots everytime I wrote back and said something about .......MSG -116........ and some other stuff i can't remember, there was three lines of errors like this for each block.

I flashed the orig back the forth time and it booted to the logo screen for a sec and then showed E71, flashed it back the fifth time and it booted up into nxe so I shut it off and made a ecc with multibuilder, flashed it and it took about 15 sec for reloaded to show. Anyways got my keys made my freeboot and flashed it using rawflash, went ok.

I powered it up and it booted up, great. I shut it off and got xex menu and the other stuff ready and went to turn on the slim and no power, just sounds when you push the power and eject button. I am stumped now because the nandx will not pick up the nand on the slim, giving me an error "looking for usb interface device"

I went and flashed a falcon the jtag way after trying this and I never had one problem at all. I went and pluged in this slim as soon as I finished the falcon and it still said looking for usb interface device.

i have no idea what to try now, I have spent days in chats, reading fourms and trying alt points, testing resistors, traces, everyone of the connections on the coolrunner, studying the board with a magnifying glass and have not resolved this problem.

I know my pinheaders have a good connection on the board and to the nandx, I have tested every wire. I have tested all traces by using a ohm meter going from the ground and a lot of different places on the board to every connection for the RGH and Nandx points, JUST TO SEE IF I HAD ANY BROKEN TRACES. If I had a broken trace I wouldn't have got a reading on the meter and I know its not how to test. Just an easier way to see if i had any broken traces.

I have read all the different fourms from all the well known sites and tried a lot of the things they said. I know my soldering to good because I HAVE NEVER HAD A PROBLEM WITH IT BEFORE!!!!! I have done 20 or 30 jtags and about 12 RGHs and never had any problems but one on my first jtag I did which was a bad block I had trouble with.

I have been kicked off of IRC #freeboot because those guys can't understand that its not a wiring problem. I sent a picture of my soldering to one of them and he said it was just as good a job as he could have done, so I don't know what to try next.......Any help would be great...

Can you post better quality images? These are all blurred.

You've either blown the resistor on STBY_CLK, damaged the trace or have damaged the 5v standby rail. Check your 5v standby voltages.

The resistor is fine by STBY_CLK reads 33ohms, Tested the trace by testing R3B15 and FT3N2 together, and by the stand by 5v rail do you mean is the coolrunner red light on when console off?

Or I should ask how do I test the standby 5v rail?

If you're getting a light on the CR etc then it should be ok.

You could have corrupted the SMC- you will need to try the NAND badflash method or use a NAND writer to erase the first block. You can erase the whole NAND if you need to.

If you're doing half as many consoles as me, invest in a progskeet with a 360 clip. You can get a NAND erased in a matter of minutes without needing to solder anything new.

Thats like one of those flashers that can flash the nand with the power unpluged from the xbox, right?

I tried the bad nand flash method on a falcon that had no power, I got the power back but still unable to read/write to the nand.

But the only thing I don't understand is why nandpro says looking for usb interface device. Its just like the console isn't pluged in, strange.

Oh yeah, I will try the recover from a bad flash method and see what happens, Thanks for the quick reply.

 

[homegrown]

how do you edit your posts?

 

[Martin C]

A corrupt SMC will stop the southbridge SPI from talking to the NAND. It caches a copy which clears after the console has been unplugged for about 20 secs.

So not only would you not be able to turn it on, but the southbridge wouldn't be able to talk to the NAND.

I know he had a hard time with the ecc, like I said he had to write the ecc three times and still was getting black screen and then red center light on ROL after 20-30 secs and the coolrunner stopped trying to glitch also. I made the ECC with multibuilder as did he but it booted reloaded for me.

Thanks Martin C, I have always read your posts and tried things you suggested, but the funny thing is that I spent 2 days trying to explain to the guys at irc #freeboot I need to do what you just told me, I got banned before I could get an answer, they kept telling its my soldering, I know a lot of people have that problem, but I am a very skilled with soldering. I know a friend of mine that has an old programer for doing the satellites, I think it should work for this.

 

[Martin C]

You can try the badflash method of shorting the I/O pins on the NAND at startup too.

I'm not saying it'll solve the problem but from what you're saying it's more likely to be.

 

[homegrown]

I'll try to find a progskeet and get a 360 clip before I try shorting the I/O pins, good to have anyways just incase I run into problems like this again. What is a good site to order it from?

 

[Martin C]

I got mine from EliteAsia - I bought the original progskeet at first for downgrading PS3s, then bought the ZIF socket for it as well as the clips for NOR and NAND. It's always good as a backup in case someone has hosed the SPI on their southbridge.

 

[homegrown]

Thanks for the tips and I hope it will fix my problem, do you know of any tuts around to help me in making sure I do this the right way, with the progskeet?

 

[Martin C]

Just follow the guides on the progskeet forums. Not a T-X product so can't really help you there.

 

[homegrown]

I found a tut on how to flash the nand on a slim with ProSkeet and posted the link if anyone else might want to try this method, thanks once again Martin C!!!!

[Martin C]

I'm guessing it worked then? So it was the SMC which was corrupt?

 

[homegrown]

Not sure yet, I am going to order a Proskeet and a 360 clip tomorrow. I will let you know what happens when I get my order, Thanks for the Quick reply Martin..

 

[x360ccm]

whats a Proskeet is that a ps3 thing.or am i being a knob.

i had a guy ring today asking about that or something on that name.

 

[homegrown]

Progskeet in another nand flasher that I wish I knew about before I bought a Nand-X. Google it and read what this little puppy can do. Sorry team xecuter for saying that, I love your products. I find the nandx can be a pain to get working sometimes.

Here is some info on it- http://www.modchipcentral.com/store...or-reader-writer-crystal-blue-usa-canada.html

Sorry about my last post, my bad. I have got that working, found out my nand-x is shot. I read in another fourm that when you program alot of coolrunners something happens to the nand-x which I guess stops it from reading and writing but will still work for programming the coolrunner. Thats Martin C for all your help and really understanding what I was talking about right off the start, thank you!
