Well I just got my Xecuter 2.6 CE installaed on my VS1 xbox. With my bank set to 2 and my write protect off I FTP'D into the box and tried to flash the BIOS x2_5035_vOld_512k.bin After it flashed and restarted it booted right back up to FLASHBIOS...Sooo I tried another bios which was Xecuter2 v1.1 Final (1024Kb).bin. (still with the switch on bank 2)This is when everything went terribly wrong. After the bios was installed the box shut down and when i turned it back on i got the Three flash FRAG thing...?! I was like oh well Ill just switch to Bank 1...well i still get the FRAG...Why in the world did it ruin both bank 1 and 2? and how can i Fix this problem? Thanks in advance! -AIM jpf566

It should have only flashed the 2nd bank.

Were you screwed up is you flashed a 1024k bios instead of 512k.

It could have possibly flashed both banks but I don't think it's supposed to do that.

If you still can't boot the 1st bank you will probably have to hotswap the chip to flash it now or order a programmer to get it working again.

do you think its possible that my bank switch is not functioning?

so with the xecuter 2.6 ce i should be using a 512 bios?

yes
x2 5035 v1.0 to v1.5 xboxs
x2 5035 v16 plus v1.6 to v1.6b xboxs

I see you have a v1.0 BOX with the Xecuter 2.6 in it. First off I was wondering if you have been able to solve your problem yet. Regardless I had a VERY similar (if not the SAME) problem. I too have a v1.0 BOX with the 2.6; and trust me I was a cross between pissed and nervous when my box started FRAG after installing the chip and flashing it (or attempting to). So I will give you *my* exact scenario, and you can run down the list to check it up with the problems you are having.
So I purchase my BOX and my mod chip. I find out it is a v1.0 box (after receiving it) and I had the Xecuter 2.6 CE mod chip. I decide to utilize the existing solder in the LPC that is only found on the 1.0 M/B and do a WIRE install for the modchip. I install the Xecuter 2.6 in my v1.0 BOX (using the wire install instead of putting the pin header on the M/B) and boot her up with the chip first disabled. Everything worked fine. Boot her up with the chip enabled; everything worked fine; it booted to the FlashBIOS as it should. I also flashed my x2 using FTP. Then for an unknown reason to me after I flashed it it started FRAG both banks! So I ran out and bought an external flashing device. Then having the external programmer flashed the thing again & seemed to have went well. Got it installed back in my BOX just to have her FRAG *AGAIN/STILL*!!! To make my long story short; after checking all solder connections with a multi-meter for continuity they all checked out fine; which really threw me for a loop. I found out (since I did the wire install) somehow {playing with it a lot} that somehow one or more of the pins on the end of the wires that go into the chip (where it would sit on the pinheader if you did the pinheader install) must not have been "seated" properly / was lose. After 'shoving' the wires/pins into the modchip PRESTO it started working =D After looking around and looking around and looking around I never really saw anyone make that complaint before (lose wires/pins on a wire install) everyone thought I was a total n00b or something and couldn't solder for crap or whatever.
So I would say before you shell out any dough on an external programmer juss double check everything of the connection nature on the inside. Rip ur BOX back open make sure all contacts have continuity. If you did do the wire install make darn sure *all* the wires are shoved into the chip. I still don't fully realize how my box booted FlashBIOS just fine and appeared to DO the flash just fine, but then couldn't boot the bios I had just flashed. But that seems to have been my case. After all was said and done like I said I am more than happy with the way mine is set up and working now. As I said after I figured everything out I have a nice 1024 (512x2) file that I made for the x 2.6 CE where bank 1 is the 5035 and bank 2 is the FlashBIOS. (PM me if you want that)
either way whether yours is juss the flash or it is a more brain stumbling problem like mine I hope you are on your way to having a fun filled future with your BOX and the X 2.6 CE in her =) once you do get it working you're gonna b in heavin trust me. I love the X 2.6 CE it is an awesome chip. You can catch me on any of the messengers (yahoo, AIM, or MSN/windows messenger) my screen name on ALL of them is BYKELIFE
