Well fission is more of a 'theme' of the core OS. It takes away all of the motoblur and motorola bloatware, and tries to give you a vanilla android look. That means, basically a non motorola messed with phone. Using a different launcher with fission is the same as using a different launcher with the stock ROM
Open up the Fission Rom Manager, select the theme you want to try. Then select the other add-ons you want to go along with it. I always select the rom again also, just to be sure. Hit the button down at the bottom (Install?- I forgot.) Then, your install cue comes up with all the selections you just made. You can select to make a backup before adding anything. Next, I always select to wipe cache just to help eliminate any problems. Then hit the Install (I think) button on the bottom one more time, and wait for the magic to happen.
So I've been trying to get a custom ROM onto my girlfriends D2G and from what I've read in the forums Fission is the only ROM that works on the D2G. Everytime I've tried to flash the ROM it loads but I have a few minor probems (by minor I mean major lol.) The first problem is the QWERTY keyboard: When I try using the QWERTY board the normal letters are fine, but when I press the shift button to use the numbers they are all in the wrong places i.e. #4 ends up being #5 and so on and so forth. The second problem is: There is no cell service!! The phone becomes useless cause it can't find the signal! WTF?!
When I reload the backup everything works fine again. I'm getting really frustrated!! I want her to have a custom ROM, but this damn phone sucks!! I've never had any issues with my X, but this Global phone is a f*#@ing nightmare!! Please help!! ANYONE!!!
