Bb512mb Jasper Jtag Help - Black Screen No Video Options

[Specter]

Hi,

I have the same issue with mine now.. everything was fine, I was playing a games in the morning and I shut off the 360.. a few hour later I try to turn it on and blackscreen with no green/red light.. I thought one of the wire was desoldered but no everything is fine and really solid... my next step is to try flashing to original nand to see if it works.

I'm wonder if this issue is related to the previous news about the Jtag Saver because the jtag point is not supposed to receive the voltage bla bla bla.. I hope my jtag is not dead.

Specter, can you boot into XELL?

In my case, I could not boot into XELL and over the weekend I re-soldered all my JTAG points - my DB1F1 was effie so I soldered to an alternate point (reverse JTAG method)

If you can boot into XELL then that means your JTAG is fine and just need to reflash XBR.

I am having a similar problem on a jasper 512 that used to have xbr3. I messed up a flash and now im trying to get freeboot to work.

Using a VGA cable.

Xellous and Xell I get video signal but not on normal boot, just a solid green light without even the rotating ring of light on boot. This is with both XBR and freeboot now.

Hey Sp00nLude.. for your information I reflashed my Xell.bin and now my xbox boot fines.. the xbox is not mine and I just learn that the last thing that my friend did with it was saving a save game on the MU and it make all sense now cause writing on the MU when using XBR is not recommanded so I will upgrade is XBR to Freeboot and he should be fine.

All my solder were fine so I knew it wasn't that... Thx for the help and hopefully it will help other people.
