OK, I have rooted my phone have a few ROMS I want to try. But I tried to use Boot Manager and it won't work on the r910. I tried talking to the developers and I got this answer:

Does anyone know of an alternative I can use for multiple ROMS?

 

Having problems with the metropcs USB drivers. It keeps truing to install Unibrain 1394 drivers and win7-64 doesn't have a 1394 port so it dumps the drivers. and won't load anything.

Suggestions?

 

I have Basix, CM7 bootsound files, LCARSboot, ufpboot. Mostly for just theming and skinning. That's what started me on this project. But now I want to see how much I can do with this phone and push its limits.

Still looking for more.

edit:
I'm also having problems with cwm. I'm trying to back up my original ROM and I keep getting this error when I boot into cwm recovery:

Code (Text):

1.  
2. E:Failed to verify whole-file signature
3. E:signature verification failed
4. Installation aborted
5.  

So how would I back up my ROM?

 

I went back to stock with Odin and then retried flashing it and now I have Basix and Electric sheep installed. It's much better for me than the stock rom and kernel. Even with the few minor glitches I get.
