Well, chalk me up as one for whom it won't work :-(.
I was on TR1.5. Downloaded nROM 1.2, nROM 1.3.1, rebooted, nand backup, flashed 1.2, rebooted and let load then rebooted again, flashed 1.3.1, rebooted and let load then rebooted again, wiped dalvik-cache, rebooted once more. Couldn't access settings, widgets wouldn't work, was very choppy and slow.
So I redownloaded 1.2, redownloaded 1.3.1, restored my nand backup to get back to TR 1.5, and went through the process once more. Same results, no settings, no widgets, slow and glitchy.
So I redownloaded 1.2, 1.3.1 again, and restored my nand, and tried again. This time, after flashing 1.2 and rebooting, it hung on the android startup screen, (the silver "android" that shimmers over and over. Tried rebooting a few times, (by removing the battery to get out of the hung android startup screen), with it hanging at the same screen.
So I restored my TR1.5 nand backup again, redownloaded 1.2, downloaded 1.3.2, (freshly released), and tried once more. Again, after flashing 1.2, it hangs on the android startup screen.
Kind of at a loss now...can still restore my nand backup after pulling the battery, so all is not lost, but I can't for the life of me get your ROM to install nick :-(.
Edit: For fun, I'm doing a full, soup to nuts wipe, data/factory reset, cache, and dalvik-cache, rebooting, and starting over. We'll see if we can't make this puppy sing.
Double Edit: huh, well that got 1.2 booting yay, onward and upward.
