Anyone come across this problem before?
This is a common effect when the chip is a clone.
Are you sure this a genuine one?Can you post a picture?

I'm having a weird problem with flashing bank 0 of a duo x2 white. I can flash bank 1 fine but bank 0 will not flash. Trying to flash bank 0 via evox fails during the erase step and results in the xbox fragging on bank 1 as well. Only thing I can do is hot swap in order to reflash bank 1.
When I first installed the chip, I did the following:
1. booted to bank 1 to flashbios screen
2. switched to bank 0 and picked a 512 bios
3. during the upload, gave me a weird error. think it was something about a 1024 bios but i don't even have any 1024 bios'!
4. tried to boot bank 1 and the xbox frags
5. had to hotswap to reflash bank 1.
Anyone come across this problem before?
Thanks
Evox flashes these chips fine if they are ok but if you flash a 1mb bios to them ( and i know you said you flashed a 512k bios ) it makes future flashes in evox all weird.
For example i have a blue duox2 clone here that if flashed with a 1 mb bios using flashbios then both banks get destroyed and further flashes through hotswap also dont work as evox now thinks the chip needs a 1mb bios !!!
To repair this kind of damage i reflash the chip using flashbios unauthorised with a 512k bios to each bank seperatly ofcourse or you can also reflash with eurasia.
hippo has bootable xbe's of flashbios unauthoriased on his website that are awesome for reflashing this kind of stuff !
Flick the bank switch back and forth a few times to ensure the bank selector is working and not halfway between both banks !

I'm having this exact same problem. I downloaded M8 1.6 bios from xbins , and used the X2 Bios Manager to resize it to 512k. I then booted up to bank 1 and used the HTTP flash method. It gave some error about not being a 1024k blah blah also which confused me. And then so I had to turn off the system and turn it back on, and frags on both banks. Eject into default mode works fine. So I guess I have to do a hot swap now. Anyone have any advice?
Yes you will have to hotswap to flash now but make sure you dont use Evox or similar. You must use Flashbios or Eurasia to flash and make sure it's a 512k bios !
