I'm running CM9, before that CM7, and before that I had a problem with my 3-button recovery I believe I was on stock 2.2 I had used a fix somewhere in the forum for the 3 button fix and it worked. But now for example if I flash a different modem and or Google apps it does flash but then I get Power Reset or Unknown Upload Mode error screen. I have to pull the battery out and it will reboot. I think this may have something to due to the boot loaders? Any help would be helpful thanks.

I think it's a product of that 3 bottom fix, which you should never flash again. To be sure, you should probably just get on gingerbread bootloaders

Reminder, probably can't flash bootloaders while on cm/ics. I think the framework difference in that and Samsung causes problems. Also, try reformatting your internal memory sd card, just back everything you want to keep up first.

Lookup any Heimdall one click GB ROMs and enable bootloaders update. Apex ROM one of them.

You technically can, but you won't be able to boot without flashing to stock from there. So don't do it

You can root from corn. It's really easy

To clarify, are you only seeing the white AT&T World Phone screen?
