E79 after Jtag - Can boot into Xell

witnessmenow

Howdy folks,

I jtagged a Jasper at the weekend there and the thing is getting an e79 error on startup after i tried to flash an image generated by bestpig(using full nand dump from xell http).

As i say in the title, it still boots into xell ok.

I did the boxdr wiring method, so i'd be surprised if i messed it up, seemed ok anyways.

Any suggestions?

Try a manual build with fbbuild, & flash with xell? No errors reported by BP or anything no?

my than likely you have bad blocks,
It happened to me when jtagging a falcon a while back.
Open the nand up in degraded to find out where the bad blocks are if you have any and your going to have to manually remap them with nand pro.

Either that or you have a hardware problem,
Flash it back to stock before you do anything else to rule out faulty hardware.

You can try what jimbobjoeyman says and search for bad blocks. There's nothing wrong with your wiring or else the Xell booting wouldn't work but there may well be something wrong with the GPU - Xell runs on the CPU only, but freeBOOT enables the GPU.

I've had two consoles that worked fine with stock firmware, worked fine for Xell but neither of which would boot into XBReboot or freeBOOT. One of them had a GPU transplant done on it by some other guy and I'm told it worked fine after that.

Now that you guys mention it I did have some bad blocks while doing a manual dump, I wasnt too worried as i got all matching dumps.

I still have my cmd window open so here is the output.

NandPro v2.0b by Tiros

The console booted ok before i jtagged it, or it least got a MS splash screen on bootup (the VGA cable in my garage is dodge city so I wasnt very patient :P )

Is there any guides for remapping the bad blocks or is this also contained in the mega thread?

It's in the Mega-thread. To be honest those blocks are outside the 0x000->0x1FF range that freeBOOT overwrites, they look to be in actual MemUnit territory.

Ok so im back to trying to sort this today.

A couple of questions, so my nand dump seems to have bad blocks and it does seem to be in valid locations to cause problems:



Also can i flash back to stock using xell (for speed more than anything)?

TouchingVirus

Flashing back to stock with Xell is possible, yes.

Bad blocks should not be moved to 1FF or 1FE ..bad blocks on 16MB are moved to 3FF and 3FE. 1FF and 1FE is not the bad-block reserved area of the nand
