from there it boots up on the xbox fine but when i try to use the 5032 it boots up, I get a screen that said "Xecuter 2.6 Config Live loading" and nothing happens
Nothing happens because you probably don't have your hard drive setup yet.
Download an auto installer (AID or SLAYERS), burn to disc, then use it to install a new custom dashboard, apps, and whatever else you want.
If it's telling you Config Live is loading... it's searching the hard drive for a custom dashboard (and finding nothing).
If i try to use any Xecuter 49XX bios it FRAGs!
You need to resize that BIOS to 512K or it'll FRAG.
each bank on the X2.6's are 512K.
Stick with X2_5035 BIOS (it was the latest one released for xbox1). It's also 512k in size already so you don't have to do any resizing.
Once you get that working nicely, you can go ahead and do as steveo stated and hotswap your chips & reflash a working BIOS to the other ones you have.
