6.1 or not?
 

I am successfully running 3.27 without any issues/bugs. I would kind of like to give 6.1 a try, but when I upgraded to 3.27 I wasn't able to use my backup (SPD) and I had to start all over again, I really don't want to do it AGAIN. So my question is, is it really worth the risk? I could care less about the SMS, I really would like to try it because of the increased speed everyone is reporting. I am also a little leery since I am running 3.27 without any issues whatsoever, I don't want to push my luck.
So has anyone went from 3.27 to 6.1 and used a backup program, and was it worth the trouble?

You can only restore a backup from a device with the same setup. IE, a backup from 2.17 can be restored to a 2.17 rom, a 3x backup to a 3x rom, and a 6.1 backup to a 6.1 rom.

since every rom changes the position of certain files and how things work (different reg entries, etc), flashing a backup from another rom type can cause unpredictable, possibly harmful effects.
That's just how it works.

So, no, unless you made the backup with a titan running the same 6.1 rom, you can't use that restore.

Well that answered my primary question, now is it REALLY worth the hassle of re-installing everything again?

EDIT: BTW thanks for the quick and helpful response.

No........ I tried it and went back to DcDs 2.0(Built off 3.16-WM 6.0).
Less memory usage and the only thing I saw different that I couldn't live without was threaded message and I got that in a app. I also had the PIE problem that a few people have with PIE not connecting.

The main thing for me is that 6.1 runs literally twice as fast for me. the phone feels so much more responsive, everything just runs faster. I would at least give it a try, if you dont like it, go back to the other rom where you can just restore your backup.

Would PIM backup still work to restore contacts?

work as always!

Oh man, I was weary making the switch from DCD's 2.0 which I had just installed and set up but I'm so glad I did. I can't believe how much more responsive the phone is now!

I used sbp backup from 2.17 to 3.x just fine. I backed up everything I could through activesync, contacts through outlook, then used spb pim + mydocs only to get my pics, videos, and txt messages. Worked a treat. Lucky?

Oh, and DCD's roms are always faster than official roms because they are stripped down to the bare minimum, then tweaked to the max. At least, usually, unless there's a full one I'm missing.... [curiously heads over to xda]
