I'm lost about this.
When I plugged my phone in RSD, it shows a R01 Vivo rom. So, I didn't try to install another rom over the Vivo rom.
But, in fact, appears that are two retail roms. And, one of them is R01 and the another one isn't. Look to the names:
This is the R01 one
And this is the another one
So, the question is, none of this roms can be installed over the Vivo/Claro/Personal rom?
Another thing. The Vivo rom cannot be rooted because the Vivo carrier solved some security issues in the rom, and with this fixes, the root cannot be made. Then, this R01 retail rom is just a retail rom with the security issues fixed? Or a Vivo (security fixed) without the Vivo stuff (I know, is the same thing)?
I'm gonna ask something. I don't know about exchange roms in Milestone 2/Droid 2, so I was wondering, there is somebody in the forum with more experience about this to try and tell us if works?
I'm afraid of switch the roms and my phone does not work again. That is the reason that I didn't yet.
And in "if works" I mean, if it is possible to put one of this retail roms over the Vivo rom and make root on it?
And going further, if this is possible, is also possible put a non-official rom, like CM7/CM9 or Miui?
