One good read ever 2 hours

[EiRUZ]

If I plug in my Nand-X I can get one full nand dump every 2 hours. If i turn the unit off and the nand-X off for 1 or 2 hours and let it sit, the very next time I plug in my xbox and nand and dump I can get a full dump. If i try and dump over and over I get 1 good dump, then 90% of a dump with errors, then 50%, then 10 seconds of a dump, then cannot detect flash controller. forever..

if i wait another hour or two and let everything cool off, I can get another full dump.

could this mean my Nand-X is bad and has a hot point somewhere?

When you are dumping yor nand; is you xbox turned on? It needs to be turned off, but plugged in. Orange light on PSU.

Leaving your xbox unplugged would clear SMC memory. Would explain why it works after a few hours. Your Nand-X is probably not the problem.

yes my Xbox is turned off when dumping and when I wait 1 or 2 hours I unplug the xbox completely. How can I clear SMC memory because if what you are saying is true, then I could just clear SMC memory and get a dump every time... I still think its a hot solder point either on the motherboard or a malfunctioning nand-x that heats up or has a bad joint somewhere when I am reading my nand it amplifies the issue.

Can't see why it would be a hot solder point (or why anything would overheat). Never heard about hot solder points either..
Are your dumps good? And did you compare them and see if they match? I bet they dont, since you turned it on and off and such, but still.
SMC memory clears when the xbox is unplugged for a while. If the nand is corrupted, you can reset it by shorting pins 44 to 47. Picture below. Can be done with a screwdriver. Note that the first pin (48) should not be shorted.

I can boot the 360 up and it runs the stock dash fine. Are you saying my nand is corrupted even if it boots? I don't have a good dump considering I have 5 dumps now and they are all a few blocks off of eachother. 3 blocks here 4 blocks there 6 blocks on another.. so I don't want to blow my nand up or make it worse until I "know" that I have the original dump... you know... So what am I doing with the screwdriver and can you explain why I would do this? and when I would do this? like do this while its plugged in but not turned on? or do this while its unplugged completely? or do this while I am trying to dump a Nand? etc... and what does it do? clears my SMC? or does it do something else?

Dont think it can boot if nand is corrupted, so you should be fine without shorting anything.
Could you post pictures of your soldering? And what error do you get, when you can't read your nand?
Btw, please use the thanks button!

I've attached two images of my soldering.. I've actually soldered them more than once considering I kept getting Flash Controller not found errors... eventually I started getting dumps, but like I said, they would degrade and eventually say Flash controller not detected.. then i wait a hour or two and I get another dump... most of the time they are full, the other rest are filled with partial errors but I have managed to get 5 complete dumps.. none of them match..

Hmm, looks okay, but hard to tell as i cant see the motherboard points (and if they are joint). Did you use flux and all? Otherwise im not sure what this is caused by.But generally, the flash controller error is a xbox/soldering problem. Or it could be a loose connection somewhere. Maybe thepins on the nand-X are bent? Maybe the usb cable is weird?

 

[EiRUZ]

I totally hear you on what you are saying... up until this job I thought I was a great solder... I used flux. I cleaned my points.. I didn't over solder.. this is actually my 3rd attempt at each point... they started with the smallest amount of solder possible to what I thought was making a connection... then they went to a little bit more, then I was like, I might as well put a tiny bubble of solder on each one..

and then I'd get random Full reads and random 90% reads but nothing consistant... one time I got 2 full dumps back to back and then Could not detect flash controller... I started to think? Hey do I have a loose wire or bad pin on the nand-x? is the nand-x faulty? it just didn't and still doesn't make sense... I mean I shouldn't get any dumps if its bad solder, so why do i get full dumps randomly... could it be Windows 7??? could it be something else on the board causing issues? could it be the JTAG section of the board? or is that unrelated to reading the nand... Some times I would just move my nand-X and I'd swear I was getting a dump.. I started to question the device, the wires, everything... I really don't wanna remove my QSB and put in pin headers cause I'd hate to do extra work if its the nand-x. and i'd hate to ruin something that was fine before I messed it up only to be a unrelated problem...

any ideas?

The JTAG part is totally unrelated to the nand part. You shouldn't have soldered it on already. Preferably after you dumped the nand.
Less solder is much better than more.

I've got one great idea. Get a multimeter, measure if you've actually got everything soldered correctly. Also, if nothing else works for you, try another computer, and soldering the wires directly. Also, you could press the nand-x reset button (through the tiny hole). I can't see why it would make things better in this case, but it cant make anything wrong.

You could also try desoldering the JTAG part, and maybe connect the rfboard, fan, AV-cable.

Just got another full dump. This one was also not a match to any previous, but it went all the way through ... then immediately after saving it, i tried again, and could not detect flash controller...

 

[EiRUZ]

I have a multimeter but have no idea how to tell if the nand-x is correct when using it... I tried pushing on different points with the multimeter and I get various numbers but don't know exactly what would be correct or what I am looking for. I've tried 2 PCs.. i've never hooked up the AV cables when dumping, only a HDMI cable but never to a PC... maybe that might help? I'll put in the fan shroud dvd drive and etc and see if that helps..

If you boot the console in between reads the nand dumps will be different.

what about if i unplug it from the wall in between reads?

so does that mean if i have 3 dumps and they all are almost identical but there are like 2 or 3 different blocks between them one of those or all 3 of those dumps are good? i have been powering it on and off in between dumps because i can only get 1 dump every 2 hours... did you read my thread? can you give me any more advice cause you are a BIG DOG on these forums so I respect any info you may have to add? is my solder bad if i get a good dump every 2 hours or is it something bigger, like maybe my QSB board is bad?

I also have the JTAG board installed, would that mess a dump up.. I also bridged the resistor point on the back to prevent blown fuses... I don't have any JTAG or xel or xellous or anything running since I am still at the "getting a good dump of your machine part.

I also just played TombRaider on the xbox for 45 minutes to make sure its good, and then immediately tried to dump after i powered it off and got could not detect flash controller. yet if i let the box sit "cool down" for 2 hours and run a dump it kicks in instantly and 95% of the time I can get a full dump... only a few times I don't get the full dump and it goes into Read 0 and wacky errors.. then after that, no more dumps "could not detect flash controller" and then i wait another hour or two and it gives me another dump.

Ok... I got some desoldering braid, took every point off... completely cleaned all the QSB's back to stock... I went to the store and got some different solder.. thinner, newer.. etc.. the other solder I had was like 10 years + old.. neway... after pulling all the old solder off with braid and applying some new flux, solder, everything is great.. I did 15 full dumps in a row. weird though was there was 1 different block from all 15 dumps.. dump 14 and 6 matched. I flashed XEL, got a E79 and flashed dump #6 back and it boots to the blade dash, so I am going to play with it more and redo the JTAG portion solder since it was that same crap solder I used on the other QSB's ! So this post is FIXED Thanks!

So, it was the soldering all along

Anyways, happy Jtagging
