Trying to undo a fubar chip

I have only installed a couple X3's and they have always went flawless. A friend of mine sent me his machine as he was having difficulty getting it flashed.

It seems he has really messed up the flashing too. The only thing I can to work is booting the chip up into backup (256k) mode and of course it boots up fine with the long press, right to MS Dash.

The install seems fine since I can actually get the backup mode to boot. I tried flashing a regular 256k bios to it like the regular M8 or X2 4983.06 but of course I get "not recognized" then halt. (no, flash protect is not on)

I thought if I could at least get a 256k bios on there and load up evox I could try to somehow clear the banks, which I don't know how to do yet. I read a few posts about X3_erase or something like that, but have no idea where to find as of yet.

Any ideas (besides putting a different chip on..lol) would be greatly appreciated. I can't believe this chip as good as it is doesn't have a "noob nuked it" switch in order to run a recovery cd like the Xenium Ice has.

I have personally tried booting this chip up in every switch configuration imaginable, so he has really put the screws to the chip. Luckily, I can still get to backup so maybe there is hope for this chip after all.

Thanks in advance for any info thrown my way.

I do see the X3_erase .xbe now...didnt even really take a look at that till now.

So, now all I need to do is figure out how to get this file ran. If I cannot boot up to Evox by getting a bios on this chip then I dont see how to accomplish the task.

Well, I actually got X2 4983 bios flashed to a 256k bank.

Installed EvoX and some other apps to the stock HD. FTP'd X3_erase xbe file to HD and ran it...

Put the switch in a 1mb setting and booted backup rom. Did the HTTP flash of the 1959 bios (box is a version 1.0) and it ran the whole way through and shut down...joy you think...nope.

Now when I boot the Xbox to this bank, the X is blue but I have no video no audio...just a blank screen.

This has got to be the freakiest chip known to man. I can still boot X2 4983 bios from the other bank...so...not sure what gives.

Gonna put a SmartXX in it...

if you can see the x2 bio's and not the x3 1959 the recheck pins 13 and 14 on the pin header.
