So, in the last 48 hours, after reading page after page, I decided to root my D2G.
Rooting was a pain in the rear. Z4 doesn't work, and S1C doesn't want to (hangs at Waiting for device). After reading several pages of the S1C support thread, I noticed someone with an HTC Eris or some other HTC phone said they had to boot the phone while S1C was "waiting for device." This worked for me. Root achieved.
Next, I installed the D2G Bootstrapper. From my experiences with flashing PSP firmwares, I know firsthand that a bootstrap recovery can be all the difference in the world between an expensive paperweight and a programmable piece of electronic hardware. Bootstrapper was easy to install, and I immediately made a backup of my phone and copied it to my computer for safe keeping. Bootstrap failsafe achieved.
I hesitated at this point because I wasn't sure whether Fission was for me. I thought, well, I can always go back. So after another several hours of research, I decided to take the plunge. What the hell, Bootstrap will save me. I launched FRM, got the Fission ROM, set it into queue, made a new backup, wiped data, and off we go. Surprisingly quick once the backup was done. Booted up immediately, and into the Android FTU stuff. ROM achieved.
Now it's a day later, and as I'm discovering exactly how much of my phone personalization is gone, the awesomeness of Fission wears off pretty fast. All of my stored text threads are gone. Progress on games (I realize this is a bit childish) is gone. Battery manager settings gone. Granted, the phone is running better than it ever has and everything works. But there are a lot of things that are different from BlurFroyo that I'm used to that are gone in Fission. Text Messaging being it's own app (Fission just has Messaging; Froyo has Messaging and Texting seperate for whatever reason); 7 Homescreens; Contacts in the Launcher; Docking Apps (Car and Multimedia); et cetera. Now I've rolled back to just before I installed Fission.
I'm back in Froyo with MotoBlur, using BloatFreezer to keep my phone running the way I want to. I just prefer Froyo over Fission. That's all.
I guess the moral of the story is this: All of this stuff was easily done at virtually no cost (I did pay like $2 or something for BloatFreezer, but who really cares about $2?) and virtually no risk. I still have root access on my phone, still have it running faster than it was before; not as fast as Fission, but faster than factory, and I still have everything I had before I went to Fission: Contacts, Progress, Settings... A journey to the center of the Droid and back.
