Here's a way to reflash the 360 after a bad flash without having to use an extra 5/3.3V power supply. Make sure you leave the power supply unplugged and don't connect the 5V line on the 360 MB at all. Never plug in the power supply while it's wired up like this! You can fry the chip and/or MB that way!
This does NOT fix the doubled byte error while flashing, just the "unable to detect flash type" after a bad flash.

hi ppl, im nu' to this forum.

i had a bad flash and i cant get AD73 type of flash to re-flash my NAND, ive dumped correctly the 2858 kernel, untouched.

if i understood correctly, i must solder the 5v points together, and then solder the 3.3v of infectus to 3.3v of da 360MB

isnt it? i dont wanna fry my whitebox :S


thx alot ppl!!

infectus is a great work!

[Arakon]

yes, exactly. and leave the 360 power supply unplugged!

[kikofras]

i cant find the 3.3v point, can you explain where's this point at the MB?

many thx

[Arakon]

directly next to the hynix tsop flash. in the picture above the hynix chip is removed, it just makes it easier to see the point. it's on the top side of the board.

i saw it after made da post, ahaha xD

thx alot!!

I tried this after a bad write f*cked up my NAND. It doesn't work.... I get an A822 now... what does this mean?

EDIT: Now I get an A000 if I try the usual way and an A872 if I add the V line to the usual way.... EDIT again: Sorry, forgot to connect the PSU.... With PSU it's A822 always...

...Never plug in the power supply while it's wired up like this! You can fry the chip and/or MB that way!...

[Chan163]

As I stated, I tried it THE USUAL WAY when the PSU was connected, not the recovery method. I NEVER connected the PSU when I tried the recovery.

I can confirm this method working. Certainly handy being to power the NAND from the Infectus chip; saved me dusting off the benchtop PSU.

I'm still not sure how I did it, but I managed to screw up flashing it the last time I used it before putting it away for a week or so, so I was a bit concerned when it didn't work when I went to turn it on. Figured out it must be a bad flash, tried to get advice on several irc chans (noone could/would/did help), and came to find this guide.

NAND was picked up right away, so I flashed it with an old 2255 dump, and read it back to confirm. md5 matched. Still haven't powered on the box yet (no reason to yet), but 99.99% certain its ok.

Thank you Infectus for such an awesome device, and Arakon for this guide. Quite plainly, I'd be screwed without it.

[laemmchen]

this method is working, but Arakon, the voltage regulator on the infectus is not to play with...
it was meant for the fpga and SST, now you're also feeding the nand flash and this is not good...
(I noticed my infectus getting very warm)

[Arakon]

it's not meant to (and not required to) power the NAND constantly, only to fix a bad flash. afterwards it can be flashed normally again.

Thanks Arakon, this worked great for me. It detected my xbox 360 nand instantly!

My turn to have a bad flash..=(

The infectus is soldered like the 1.4 diagram
(http://www.infectus.biz/diagrams/Xbox360_1b.JPG)

I made some dumps of 5759, (they where all the same checked with
md5 and they where working in robinsods dump tool), then i
upgraded to 5787 and dumped som more, they where also all the same.

So i thought why not downgrade(to 5759) to see if it would work.
I used the 3.6 beta 1, but i instantly got a write error(all
zeros i think it was, not sure) and now it doesnt recognize
the flash anymore.

Then i tried the way stated in this thread but all i get in the
infectus program is either AAAA or FFFF, i have tried diffrent
versions to( 3.5beta 2, 3.4d and the new 0.0 or what its called.)
I never had the power supply pluged in while the "bad flash fix"
was soldered.
i have also resoldered the infectus but it didnt help. =(

maybe i've made som other mistake and fried my nand or maybe
destroyed some solderpoints, i dont know.. what do you all think
about this??



I was thinking about getting someone to hook up the alternative
solder points me.. maybe that can help?
