E79 - During failed update, any way to recover?

[Dark Neo]

I had a dumb moment and attempted to run a recovery from my HDD

As a result, the box now boots to an error screen showing E79 .

I have tried many different recovery isos, and all of them do the same thing, i no longer receive the E79 error, it will just sit there on a black screen.

The box is a HDMI model (Demo Kit)

I also have an infectus 2, and have make a NAND Dump (66MB).

I am wondering if anyone has any suggestions on how i could get this box back to life, before i bite the bullet and purchase another?

Thanks for reading

EDIT:

Here it´s the NAND Dump in Hex Editor:

Don't bite the bullet just yet mate...

Video
1. Have you lost analog video, HDMI or both?

NAND
2. Do you have your CPU key?
3. Is your Infectus software devkit compatible? Some tools detect the devkit NAND chip, but make empty dumps.... (there should be a MS copyright notice in the beginning of your dump, so you might have an empty dump)

That NAND Dump looks empty, I remember hearing that Infectus doesn't work with devs or something to that effect. I think a similar situation to this has happened to gamerfreak, your probably going to need a way to program the NAND chip with a functional dump.

Yea you basically need a working Nand to get your kit back to working.

Also Gamerfreak was in the middle of recovery then his power when out but resulted in the same effect.

But fixing this error is a hit or miss.

I haven´t a working NAND Dump , only this one.:-(

Do you have your CPU key? And did you double check that both HDMI and analog video signal are gone?

How? The Kit is 10min. old and i have only this Dump, nothing other.

I was just hoping you had a backup of your key, since that pairs the NAND and the CPU. Since your backup dump is empty, converting another dump could have been an option.

What about video? It is quite common to lose analog video, but that HDMI is still working, on some of these units....

Do not try to restore or erase the NAND in the faulty unit, before you have a proper dump of it. Maybe the keyvault can be saved....

oh lawl

Wow,you must have a very good friend with very good contacts.
Nicely done:thumbsup:

Id love to be able to return mine for a new one lol

He meant dvd key...
That one is regenerated with certain recoveries.

[schwatter]

Yes and i think only with DVD-Recovery. Not over remote.

I also heard its random.

I would suspect if you had a side car or an infectus chip you might be able to fix it. In a flash you are usually doing two parts one upating the boot memory and then the flash drive with a new dash and boot files. I know if it was just the flash drive you would get a e79 but if you put in the disc again it would go through it. Sometimes it can take a couple of times. The other part you are updating memory and were it points to. So if it is bad you need to be able to step thorugh it to see were it is off.

what would a sidecar do to this matter?
infectus is not needed... just pop in the recovery disc and use a WIRED controller

Interesting - that implies that the KV on dev boxes has to get regenerated (unlike retail boxes). I can dump the KV before and after a dev update and check...

I my opinion an Infectus is very handy. Remember that it is easy to lose video and network support on those early Zephyrs. I have not gotten a recovery disc to fix those problems - have you?
