X2.6CE Died after hot swap

[nickb834]

Guys I need some expert opinion on what I have done. Basically whilst trying to resurrect a bad flashed modchip (Used Euarasia Pro Flash Disc which happily erased but refused to program) I have killed my 2.6CE.

I booted succesfully using my 2.6CE, swapped it out for the faulty chip, flashed and then turned Xbox off.

I re-installed my 2.6CE and got fragging.

I checked the Pin header and.........

The chip was mis aligned.

So, Pin 1 on the X2 was connected to pin 3 of the LPC etc etc - so the ground pins got 3.3v instead of 0, 5v got 3.3 and LCLOCK[GULP] got 3.3v instead of 0.2v.

Now I'm hoping that all I have done is erased / corrupted the flash and that I can re-flash this to recover?

I am worried by giving the LCLOCK 3.3v, although seeing as I raised the grounds to 3.3v also that this shouldn't matter - seeing as the potential difference between the two is 0.0v?

The chip is I am fairly sure the problem as this chip installed in another Xbox produces the same symptoms so I am fairly sure my Xbox's LPC is fine on the one I used to hot swap.

I checked the voltages on the LPC using my fluke multimeter and they all appear to fall within 0.05v of what is generally accepted (All 16 pins 3.3v except 1, 2, 6, 12 which are 0.2v, 0.0v, 5.0v, and 0.0v respectively).

The chip when installed is enabled as the Blue D0 Led is lit, basically the symptoms I get are exactly what you would expect for a bad flash.

Also I checked the resistors and diodes on the X2 and they are all fine which leaves me with these questions:

Have I erased / corrupted the flash on the X2?
Have I fried the flash?

What do you guys think?

Thanks

Nick

My apologies for the incredibly low post count, but in the three years of modchipping (Admittedly only 8 Xboxes) I have never had a problem I couldn't fix on my own.

Kinda ironic isn't it that the chip I was trying to repair was a cheapo Duo X2 - that'll serve me right! Although in atonement I have bought an X2.6CE and an X3CE this week.

sorry to hear that m8.... thats the sort of luck i usualy have(try to help a m8 and kill my own gear..grrrrr)

that was one of the reasons the the 5 volt pin header was removed in the mod as people were loosing tracks on the chip board,try a reflash (looks like a swap method yet again)

does your xbox boot from the msdash? if not you may have cooked a track on the rear of your mobo, remember the 5 volts if it was connected to the seperate jumper on the board would have shot down the next pin to it .

so 5 volts would have gone down pin 8 and ground would have gone down pin 14 thats if the 2.6ce had been fitted (looking from the front of your xbox) 1 space offset towards the front of the xbox front,as i cant see it being fitted 1 space offset away from the front of the xbox due to the pin header having a pin stopper at pin 16.

let us know if your box boots without the mod chip if it doesnt i would check under the main board for burnt tracks.....baz

Woops, Kinda forgot to mention if my Xbox was fine....

But yeah it is - it boots the MS Dash fine and using an X3 it boots my XBMC (Use it as dash) so I'm 99.999% Sure my xbox is fine.

I'm about to hot swap with an X3 and see what happens......

well dont get caught out again m8 watch those pins on the header,lets know if it works m8.... baz

check the switch bank if it doesnt incase a switch has went open circuit (best of luck)

Ok I think this 2.6 is dead.

I have booted of an X3 ok, and then swapped out the X3 for the faulty X2.6. But when I try to launch FlashX the Xbox hangs. If I try to launch FlashX with the X3 in (To make sure FlashX is actually installed ok) it comes up correctly but says that either no Xecuter 2.x chip or write protected.

If I try to use Slayers 2.6 to flash the X2.6 it comes up with Unknown device found manufacturer=0x09 device=0x00

Now if I remember rightly this means that it thinks the chip is write protected (Even though it definately isn't)

Eurasia Pro Flash disc gives the same but tbh I don't think raincoat likes it if you remove a chip from the LPC and then hot swap another in it's place.

I'll try flashing flashbios 3.0.3 back to the X3 and hotswap with that and see what it makes of it.

BTW With my X2.6 I can definately only offset it towards the rear NOT the front (I am sure I have it the right way round as it did work and it does say "This side to edge of case") so in my case it was X2.6's pin 4 got the 5v blast.

Also I have been doing all of this with the switch banks removed to ensure that the chips default to exactly what I want / need.

NP nick atleast you can rule out that you havnt damaged the switch bank (but dont you need the switch connected?) as pin 3 and 4 need to be shorted to enable write to the flash and pin 5 and 6 need to be shorted to make the chip spring to life(blue led comes on).

also pin 2 and 4 enable /disable the mod chip
i would keep the switch connected and try booting on both banks if no joy try a reflash

with the switch disconnected your defaulting to bank2,chip write disabled and no power to the chip too

heres a link to the switch info

Don't forget the chip itself has a Flash enable disable switch, and that the switch atually opens the D0 contact when you close it.

With the switches disconnected the D0 is grounded by default (Thus enabling the chip). This is by design as some people dont want to use the external switches.

Thanks for the diagram which is great but you are mis informed about the switch bank.

Trust me, with the switch disconnected the chip defaults to always enabled, and relies on the built in switch for flash protect unprotect.

Check this pic, I know it's for the X3 but it is the same idea:

Besides which, another working 2.6 on the same xbox minus it's switches works just fine - why dont you try it and see what happens, remove the cable from the back of the switches (So you don't even have to open the Xbox) and I think you'll be in for a nice little surprise
