Oops... Some help unbricking my e250 please!

Oops. I forgot to rename my compiled RB bootloader from .bin to .rom...
Could I please have some help unbricking it?
It doesn't seem to want to enter manufacturer mode; It looks just like it does when in manufacturer mode, but doesn't appear like Vista is recognising it.
I had no problem fixing the broken BL a couple days ago, but am having a little trouble fixing the i2c ROM...
Maybe I could have more luck on my OS X machine, but libusb got a compile error. could someone provide a libusb precompiled build for OS X? I got compile errors, and the version I found on the 'net is the v0.1, and i think e200tool needs 1.x
If it isn't actually in manufacturer mode, are there some contacts i could short on the circut board to make it enter recovery mode or something?

Can you be more specific? What were you doing and why did you need to rename it?

I think thats normal. manufacturer mode requires e200tool, and that doesn't work with Windows. See this page for more info about that mode:

...but i got e200tool to work on windows to reflash the bootloader, following instructions on an old revision in the RB twiki. I think it was the old e200r install page.
Oh, and since I have a corrupted i2c ROM, its in pre-boot mode, right?

We read today from the holy wiki, chapter SansaE200Unbrick, verse Pre-boot Mode:
--- Quote ---If the Sansa is booted and discovers a corrupted i2c rom or if there is no working bootloader at all, it will enter manufacturing mode automatically. During this mode, the Sansa appears as a "PortalPlayer USB Device."

Said bolded words of scripture appear to be the way to diagnose if you are in pre-boot mode.
Not saying you don't have a corrupted i2c ROM, but why do you believe you do?
Please read the whole page (quote is a link), and pay particular note to what I bolded. Even if you are in pre-boot mode it does not necessarily mean you have a corrupted i2c ROM.

"e200tool" for Windows on http://www.rockbox.org/twiki/bin/view/Main/SansaE200RInstallation ?
I don't think so. Are you sure that is the name of the tool you used? Are you sure that is the page you're talking about? You're in this position due to failure to be precise in your actions. Let's be precise in our words.

Because I copied a .bin file to the recovery mode partition. I forgot to rename it BL_SD_boardSupportSD.rom, and instead copied it as bootloader.bin
.bin files get written to the i2c rom.
PS: why was this moved to instalation/removal? I just want to fix the i2c rom, RB is allready installed, and i want to keep it that way, as putting RB on it was the purpose I had for it when I got it; the OF is a disaster.
PPS: Oh, and the computer doesn't recognise it as anything apon plugging it in.
oh, and i needed to rename it because I was building my own bootloader.
